Organization, Consolidation and Presentation of Financial Statements [Abstract]
General	GENERAL General and basis of presentation —“Delphi,” the “Company,” “we,” “us” and “our” refer to Delphi Automotive PLC, a public limited company which was formed under the laws of Jersey on May 19, 2011 , together with its subsidiaries, including Delphi Automotive LLP, a limited liability partnership incorporated under the laws of England and Wales which was formed on August 19, 2009 for the purpose of acquiring certain assets of the former Delphi Corporation (the "Acquisition"), and became a subsidiary of Delphi Automotive PLC in connection with the completion of the Company’s initial public offering on November 22, 2011 . The consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”). All adjustments, consisting of only normal recurring items, which are necessary for a fair presentation, have been included. The consolidated financial statements and notes thereto included in this report should be read in conjunction with Delphi's 2016 Annual Report on Form 10-K. Nature of operations —Delphi is a leading global technology company serving the automotive sector. Delphi designs and manufactures vehicle components and provides electrical and electronic, powertrain and safety technology solutions to the global automotive and commercial vehicle markets. Delphi operates manufacturing facilities and technical centers utilizing a regional service model that enables the Company to efficiently and effectively serve its global customers from best cost countries. In line with the long term growth in emerging markets, Delphi has been increasing its focus on these markets, particularly in China, where the Company has a major manufacturing base and strong customer relationships. Powertrain Spin-Off and Renaming of Remaining Company— On May 3, 2017 , the Company announced its intention to pursue a separation of its Powertrain Systems segment into a new, independent publicly traded company, through a transaction expected to be treated as a tax-free spin-off to its shareholders (the "Separation"). The new publicly traded Powertrain spin-off company will be named Delphi Technologies PLC, and will trade on the New York Stock Exchange ("NYSE") under the symbol "DLPH" following the distribution date. Upon completion of the Separation, the remaining company will change its name to Aptiv PLC, pending shareholder approval. Following the distribution date, Aptiv PLC will trade on the NYSE under the ticker symbol "APTV". Refer to Note 22. Separation of Powertrain Systems for additional detail.

Accounting Policies [Abstract]
Significant Accounting Policies	SIGNIFICANT ACCOUNTING POLICIES Consolidation —The consolidated financial statements include the accounts of Delphi and U.S. and non-U.S. subsidiaries in which Delphi holds a controlling financial or management interest and variable interest entities of which Delphi has determined that it is the primary beneficiary. Delphi’s share of the earnings or losses of non-controlled affiliates over which Delphi exercises significant influence (generally a 20% to 50% ownership interest) is included in the consolidated operating results using the equity method of accounting. When Delphi does not have the ability to exercise significant influence (generally when ownership interest is less than 20%), investments in non-consolidated affiliates are accounted for using the cost method. All significant intercompany transactions and balances between consolidated Delphi businesses have been eliminated. The Company monitors its investments in affiliates for indicators of other-than-temporary declines in value on an ongoing basis. If the Company determines that such a decline has occurred, an impairment loss is recorded, which is measured as the difference between carrying value and estimated fair value. Estimated fair value is generally determined using an income approach based on discounted cash flows or negotiated transaction values. During the three and nine months ended September 30, 2017 , Delphi received a dividend of $7 million from one of its equity method investments. During the three and nine months ended September 30, 2016 , Delphi received dividends of $4 million and $8 million , respectively, from one of its equity method investments. The dividends were recognized as a reduction to the investment and represented a return on investment included in cash flows from operating activities. Investments in affiliates accounted for under the cost method totaled $77 million and $26 million as of September 30, 2017 and December 31, 2016 , respectively, and are classified within other long-term assets in the consolidated balance sheet. Use of estimates —Preparation of consolidated financial statements in conformity with U.S. GAAP requires the use of estimates and assumptions that affect amounts reported therein. Generally, matters subject to estimation and judgment include amounts related to accounts receivable realization, inventory obsolescence, asset impairments, useful lives of intangible and fixed assets, deferred tax asset valuation allowances, income taxes, pension benefit plan assumptions, accruals related to litigation, warranty costs, environmental remediation costs, contingent consideration arrangements, worker’s compensation accruals and healthcare accruals. Due to the inherent uncertainty involved in making estimates, actual results reported in future periods may be based upon amounts that differ from those estimates. Net income per share —Basic net income per share is computed by dividing net income attributable to Delphi by the weighted average number of ordinary shares outstanding during the period. Diluted net income per share reflects the weighted average dilutive impact of all potentially dilutive securities from the date of issuance and is computed using the treasury stock method by dividing net income attributable to Delphi by the diluted weighted average number of ordinary shares outstanding. See Note 12. Shareholders’ Equity and Net Income Per Share for additional information including the calculation of basic and diluted net income per share. Cash and cash equivalents —Cash and cash equivalents are defined as short-term, highly liquid investments with original maturities of three months or less. Cash in escrow related to Powertrain Spin-off debt —As of September 30, 2017 , the Company deposited into escrow $796 million of net proceeds from the issuance of $800 million principal amount of unsecured senior notes by Delphi Technologies PLC, a wholly owned subsidiary of the Company formed in connection with the planned spin-off of the Company's Powertrain Systems segment, which prior to October 10, 2017 was named Delphi Jersey Holdings plc. These proceeds will be released to Delphi Technologies PLC upon satisfaction of certain conditions, including completion of the Separation. At December 31, 2016 , there was no cash in escrow for this purpose. Refer to Note 8. Debt for further description of this senior notes offering. Accounts receivable —Delphi enters into agreements to sell certain of its accounts receivable, primarily in North America and Europe. Sales of receivables are accounted for in accordance with FASB Topic ASC 860, Transfers and Servicing ("ASC 860"). Agreements which result in true sales of the transferred receivables, as defined in ASC 860, which occur when receivables are transferred without recourse to the Company, are excluded from amounts reported in the consolidated balance sheets. Cash proceeds received from such sales are included in operating cash flows. Agreements that allow Delphi to maintain effective control over the transferred receivables and which do not qualify as a sale, as defined in ASC 860, are accounted for as secured borrowings and recorded in the consolidated balance sheets within accounts receivable, net and short-term debt. The expenses associated with receivables factoring are recorded in the consolidated statements of operations within interest expense. Intangible assets —Intangible assets were $1,213 million and $1,240 million as of September 30, 2017 and December 31, 2016 , respectively. Delphi amortizes definite-lived intangible assets over their estimated useful lives. Delphi has definite-lived intangible assets related to patents and developed technology, customer relationships and trade names. Indefinite-lived in-process research and development intangible assets are not amortized, but are tested for impairment annually, or more frequently when indicators of potential impairment exist, until the completion or abandonment of the associated research and development efforts. The Company also has intangible assets related to acquired trade names that are classified as indefinite-lived when there are no foreseeable limits on the periods of time over which they are expected to contribute cash flows. These indefinite-lived trade name assets are tested for impairment annually, or more frequently when indicators of potential impairment exist. Costs to renew or extend the term of acquired intangible assets are recognized as expense as incurred. Amortization expense was $34 million and $100 million for the three and nine months ended September 30, 2017 and $34 million and $101 million for the three and nine months ended September 30, 2016 , respectively. Goodwill —Goodwill is the excess of the purchase price over the estimated fair value of identifiable net assets acquired in business combinations. The Company tests goodwill for impairment annually in the fourth quarter, or more frequently when indications of potential impairment exist. The Company monitors the existence of potential impairment indicators throughout the fiscal year. The Company tests for goodwill impairment at the reporting unit level. Our reporting units are the components of operating segments which constitute businesses for which discrete financial information is available and is regularly reviewed by segment management. The impairment test involves first qualitatively assessing goodwill for impairment. If the qualitative assessment is not met the Company then performs a quantitative assessment by first comparing the estimated fair value of each reporting unit to its carrying value, including goodwill. Fair value reflects the price a market participant would be willing to pay in a potential sale of the reporting unit. If the estimated fair value exceeds carrying value, then we conclude that no goodwill impairment has occurred. If the carrying value of the reporting unit exceeds its estimated fair value, a second step is required to measure possible goodwill impairment loss. The second step includes hypothetically valuing the tangible and intangible assets and liabilities of the reporting unit as if the reporting unit had been acquired in a business combination. Then, the implied fair value of the reporting unit's goodwill is compared to the carrying value of that goodwill. If the carrying value of the reporting unit's goodwill exceeds the implied fair value of the goodwill, the Company recognizes an impairment loss in an amount equal to the excess, not to exceed the carrying value. There were no indicators of potential goodwill impairment during the nine months ended September 30, 2017 . Goodwill was $1,670 million and $1,508 million as of September 30, 2017 and December 31, 2016 , respectively. Warranty and product recalls —Expected warranty costs for products sold are recognized at the time of sale of the product based on an estimate of the amount that eventually will be required to settle such obligations. These accruals are based on factors such as past experience, production changes, industry developments and various other considerations. Costs of product recalls, which may include the cost of the product being replaced as well as the customer’s cost of the recall, including labor to remove and replace the recalled part, are accrued as part of our warranty accrual at the time an obligation becomes probable and can be reasonably estimated. These estimates are adjusted from time to time based on facts and circumstances that impact the status of existing claims. Refer to Note 6. Warranty Obligations for additional information. Discontinued operations —The Company reports financial results for discontinued operations separately from continuing operations to distinguish the financial impact of disposal transactions from ongoing operations. Discontinued operations reporting occurs only when the disposal of a component or a group of components of the Company represents a strategic shift that will have a major effect on the Company's operations and financial results. During the year ended December 31, 2015, Delphi completed the divestitures of the Company's wholly owned Thermal Systems business and the Company's interest in its KDAC joint venture. During the nine months ended September 30, 2016 , Delphi completed the divestiture of its interest in its Shanghai Delphi Automotive Air Conditioning ("SDAAC") joint venture. Delphi's interests in the KDAC and SDAAC joint ventures were previously reported within the Thermal Systems segment. Accordingly, the assets and liabilities, operating results and operating and investing cash flows for the previously reported Thermal Systems segment are presented as discontinued operations separate from the Company’s continuing operations and segment results for all periods presented in these consolidated financial statements and the notes to the consolidated financial statements, unless otherwise noted. Refer to Note 21. Discontinued Operations for further information regarding the Company's discontinued operations. Income taxes —Deferred tax assets and liabilities reflect temporary differences between the amount of assets and liabilities for financial and tax reporting purposes. Such amounts are adjusted, as appropriate, to reflect changes in tax rates expected to be in effect when the temporary differences reverse. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in earnings in the period that includes the enactment date. A valuation allowance is recorded to reduce deferred tax assets to the amount that is more likely than not to be realized. In the event the Company determines it is more likely than not that the deferred tax assets will not be realized in the future, the valuation allowance adjustment to the deferred tax assets will be charged to earnings in the period in which the Company makes such a determination. In determining the provision for income taxes for financial statement purposes, the Company makes certain estimates and judgments which affect its evaluation of the carrying value of its deferred tax assets, as well as its calculation of certain tax liabilities. Refer to Note 11. Income Taxes for additional information. Restructuring —Delphi continually evaluates alternatives to align the business with the changing needs of its customers and to lower operating costs. This includes the realignment of its existing manufacturing capacity, facility closures, or similar actions, either in the normal course of business or pursuant to significant restructuring programs. These actions may result in employees receiving voluntary or involuntary employee termination benefits, which are mainly pursuant to union or other contractual agreements. Voluntary termination benefits are accrued when an employee accepts the related offer. Involuntary termination benefits are accrued upon the commitment to a termination plan and when the benefit arrangement is communicated to affected employees, or when liabilities are determined to be probable and estimable, depending on the existence of a substantive plan for severance or termination. Contract termination costs are recorded when contracts are terminated or when Delphi ceases to use the leased facility and no longer derives economic benefit from the contract. All other exit costs are expensed as incurred. Refer to Note 7. Restructuring for additional information. Customer concentrations —As reflected in the table below, combined net sales from continuing operations to General Motors Company ("GM") and Volkswagen Group ("VW"), Delphi's two largest customers, totaled approximately 19% and 21% of our total net sales for the three and nine months ended September 30, 2017 , respectively, and 23% and 22% for the three and nine months ended September 30, 2016 respectively. Percentage of Total Net Sales Accounts and Other Receivables Three Months Ended September 30, Nine Months Ended September 30, September 30, December 31, 2017 2016 2017 2016 (in millions) GM 11 % 15 % 13 % 14 % $ 291 $ 370 VW 8 % 8 % 8 % 8 % 205 150 Retrospective changes —Prior period information has been reclassified as a result of the Company's adoption of Accounting Standards Update ("ASU") 2017-07, as defined and further described below, on a retrospective basis in 2017. In accordance with the adoption of this guidance, prior year amounts related to the components of net periodic pension and postretirement benefit cost other than service costs have been reclassified from cost of goods sold and selling, general and administrative expense to other expense within the consolidated statement of operations for all periods presented. Recently adopted accounting pronouncements —Delphi adopted ASU 2015-11, Inventory (Topic 330): Simplifying the Measurement of Inventory , in the first quarter of 2017 on a prospective basis. This guidance requires an entity to measure inventory at the lower of cost and net realizable value, rather than at the lower of cost or market. The adoption of this guidance did not have a significant impact on Delphi's financial statements. Delphi adopted ASU 2016-05, Derivatives and Hedging (Topic 815): Effect of Derivative Contract Novations on Existing Hedge Accounting Relationships and ASU 2016-06, Derivatives and Hedging (Topic 815): Contingent Put and Call Options in Debt Instruments in the first quarter of 2017 on a prospective basis. ASU 2016-05 clarifies that a change in the counterparty to a derivative instrument that has been designated as a hedging instrument does not, in and of itself, require dedesignation of that hedging relationship provided that all other hedge accounting criteria continue to be met. ASU 2016-06 also clarifies the steps required to determine bifurcation of an embedded derivative. The adoption of this guidance did not have a significant impact on Delphi's financial statements. Delphi adopted ASU 2016-09, Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting ("ASU 2016-09") in the first quarter of 2017. This guidance contains multiple updates related to the accounting and financial statement presentation of share-based payment transactions. The provisions of ASU 2016-09 related to the timing of when excess tax benefits are recognized were adopted using a modified retrospective transition method by means of an immaterial cumulative-effect adjustment to equity as of January 1, 2017. On a prospective basis, excess tax benefits are recognized within income tax expense in the period in which the awards vest, as opposed to being recognized in additional paid-in capital when the deduction reduced taxes payable. Such excess tax benefits are classified as an operating activity within the consolidated statement of cash flows prospectively, as opposed to a financing activity. There was no change to the Company's historical presentation of minimum statutory withholdings as a financing activity within the consolidated statement of cash flows. The Company’s share-based compensation expense continues to reflect estimated forfeitures. The adoption of ASU 2016-09 did not materially impact the Company’s financial position, results of operations, equity or cash flows. Delphi adopted ASU 2017-07, Compensation—Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost ("ASU 2017-07") in the first quarter of 2017. ASU 2017-07 changes the presentation of net periodic pension and postretirement benefit cost in the income statement. Under the new guidance, employers present the service cost component of the net periodic benefit cost in the same income statement line items as other employee compensation costs for services rendered during the period. In addition, only the service cost component is eligible for capitalization as an asset. Employers present the other components of net periodic benefit cost separately from the income statement line items that include the service cost component, outside of operating income. The new guidance is effective for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. Early adoption is permitted as of the beginning of an annual period. The new guidance related to the presentation of the components of net periodic benefit cost within the income statement is to be applied retrospectively. The new guidance limiting the capitalization of net periodic benefit cost in assets to the service cost component will be applied prospectively. As permitted, the Company elected to early adopt this guidance effective January 1, 2017, and has classified the components of net periodic pension and postretirement benefit cost other than service costs from cost of goods sold and selling, general and administrative expense to other expense within the consolidated statement of operations for all periods presented. The adoption of this guidance resulted in the reclassification of $3 million and $9 million of net periodic benefit cost components other than service cost from operating expense to other expense for the three and nine months ended September 30, 2016 , respectively, and had no impact on net income attributable to Delphi. Approximately $9 million and $25 million of net periodic benefit cost components other than service cost are included within other expense for the three and nine months ended September 30, 2017 , respectively. Refer to Note. 9. Pension Benefits for further detail of the components of net periodic benefit costs. Recently issued accounting pronouncements not yet adopted —In May 2014, the Financial Accounting Standards Board ("FASB") issued ASU 2014-09, Revenue from Contracts with Customers . This ASU supersedes most of the existing guidance on revenue recognition in Accounting Standards Codification ("ASC") Topic 605, Revenue Recognition and establishes a broad principle that would require an entity to recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. To achieve this principle, an entity identifies the contract with a customer, identifies the separate performance obligations in the contract, determines the transaction price, allocates the transaction price to the separate performance obligations and recognizes revenue when each separate performance obligation is satisfied. The FASB has subsequently issued additional ASUs to clarify certain elements of the new revenue recognition guidance. The guidance is effective for fiscal years beginning after December 15, 2017 and is to be applied retrospectively using one of two transition methods at the entity's election. The full retrospective method requires companies to recast each prior reporting period presented as if the new guidance had always existed. Under the modified retrospective method, companies would recognize the cumulative effect of initially applying the standard as an adjustment to opening retained earnings at the date of initial application. The Company has continued to monitor FASB activity related to the new standard, and has worked with various non-authoritative industry groups to assess certain interpretative issues and the associated implementation of the new standard. The Company has drafted its accounting policy for the new standard based on a detailed review of its business and contracts. While the Company continues to assess all potential impacts of the new standard, we do not currently expect that the adoption of the new revenue standard will have a material impact on our revenues, results of operations or financial position. As a result of the adoption of this standard, the Company expects to make additional disclosures related to the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers as required by the new standard. The Company plans to adopt the new revenue standard effective January 1, 2018. The Company currently intends to adopt the new standard using the modified retrospective method, and continues to evaluate the effect of the standard on our ongoing financial reporting. In January 2016, the FASB issued ASU 2016-01, Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities. This guidance makes targeted improvements to existing U.S. GAAP for financial instruments, including requiring equity investments (except those accounted for under the equity method of accounting, or those that result in consolidation of the investee) to be measured at fair value with changes in fair value recognized in net income as opposed to other comprehensive income; requiring entities to use the exit price notion when measuring the fair value of financial instruments for disclosure purposes; requiring separate presentation of financial assets and financial liabilities by measurement category and form of financial asset; and requiring entities to present separately in other comprehensive income the portion of the total change in the fair value of a liability resulting from a change in the instrument-specific credit risk (also referred to as “own credit”) when the organization has elected to measure the liability at fair value in accordance with the fair value option. The new guidance is effective for public companies for fiscal years beginning after December 15, 2017 by means of a cumulative-effect adjustment to the balance sheet as of the beginning of the fiscal year of adoption. Early adoption of the own credit provision is permitted. The Company is currently evaluating the impact that the adoption of this guidance will have on its consolidated financial statements; however, based on the nature of financial instruments held by Delphi as of September 30, 2017 , the Company does not currently expect that the adoption of ASU 2016-01 will have a material impact on its financial position, results of operations or cash flows. The Company will continue to evaluate any changes in its investments or market conditions, and the related potential impacts of the adoption of ASU 2016-01. In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842) . Under this guidance, lessees will be required to recognize on the balance sheet a lease liability and a right-of-use asset for all leases, with the exception of short-term leases. The lease liability represents the lessee's obligation to make lease payments arising from a lease, and will be measured as the present value of the lease payments. The right-of-use asset represents the lessee’s right to use a specified asset for the lease term, and will be measured at the lease liability amount, adjusted for lease prepayment, lease incentives received and the lessee’s initial direct costs. The standard also requires a lessee to recognize a single lease cost allocated over the lease term, generally on a straight-line basis. The new guidance is effective for fiscal years beginning after December 15, 2018. ASU 2016-02 is required to be applied using the modified retrospective approach for all leases existing as of the effective date and provides for certain practical expedients. Early adoption is permitted. The Company is currently evaluating the effects that the adoption of ASU 2016-02 will have on the Company’s consolidated financial statements, and anticipates the new guidance will significantly impact its consolidated financial statements as the Company has a significant number of leases. In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments . This guidance requires the measurement of all expected credit losses for financial assets held at the reporting date based on historical experience, current conditions and reasonable and supportable forecasts. This guidance also requires enhanced disclosures regarding significant estimates and judgments used in estimating credit losses. The new guidance is effective for fiscal years beginning after December 15, 2019. Early adoption is permitted for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018. The Company is currently evaluating the impact that the adoption of this guidance will have on its consolidated financial statements. In September 2016, the FASB issued ASU 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments . This guidance clarifies the presentation requirements of eight specific issues within the statement of cash flows. The new guidance is effective for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. Early adoption is permitted. The adoption of this guidance is not expected to have a significant impact on Delphi's financial statements, as Delphi's treatment of the relevant affected items within its consolidated statement of cash flows is consistent with the requirements of this guidance. In October 2016, the FASB issued ASU No. 2016-16, Accounting for Income Taxes: Intra-Entity Asset Transfers of Assets Other than Inventory . This guidance requires that the tax effects of all intra-entity sales of assets other than inventory be recognized in the period in which the transaction occurs. The new guidance is effective for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. Early adoption as of the beginning of an annual reporting period is permitted. The guidance is to be applied on a modified retrospective basis through a cumulative-effect adjustment to retained earnings as of the beginning of the period of adoption. The Company is currently evaluating the impact that the adoption of this guidance will have on its consolidated financial statements. In November 2016, the FASB issued ASU 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash . This guidance requires that a statement of cash flows explain the change during the period in the total of cash, cash equivalents, and restricted cash. As a result, restricted cash will be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. The new guidance is effective for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. Early adoption is permitted, and the new guidance is to be applied retrospectively. The adoption of this guidance is not expected to have a significant impact on Delphi's financial statements, other than the classification of restricted cash within the beginning-of-period and end-of-period totals on the consolidated statement of cash flows, as opposed to being excluded from these totals. In January 2017, the FASB issued ASU 2017-04, Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment . This guidance simplifies how an entity is required to test goodwill for impairment by eliminating step two from the goodwill impairment test, which measures a goodwill impairment loss by comparing the implied fair value of a reporting unit’s goodwill with the carrying amount. Under the new guidance, if a reporting unit’s carrying amount exceeds its fair value, an entity will record an impairment charge based on that difference. The impairment charge will be limited to the amount of goodwill allocated to that reporting unit. The standard will be applied prospectively and is effective for annual and interim impairment tests performed in periods beginning after December 15, 2019. Early adoption is permitted. The Company is currently evaluating the impact of adopting this standard on its financial statements, but does not anticipate a material impact. As this standard is prospective in nature, the impact to Delphi's financial statements of not performing a step two in order to measure the amount of any potential goodwill impairment will depend on various factors associated with the Company's assessment of goodwill for impairment in those future periods. In August 2017, the FASB issued ASU 2017-12, Derivatives and Hedging - Targeted Improvements to Accounting for Hedging Activities , which expands and refines the application of hedge accounting for both non-financial and financial risk components and aligns the recognition and presentation of the effects of the hedging instrument and the hedged item in the financial statements. The standard is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early adoption is permitted. The Company is currently evaluating the impact that the adoption of this guidance will have on its consolidated financial statements.

Warranty Obligations

Product Warranties Disclosures [Abstract]
Warranty Obligations	WARRANTY OBLIGATIONS Expected warranty costs for products sold are recognized principally at the time of sale of the product based on an estimate of the amount that eventually will be required to settle such obligations. These accruals are based on factors such as past experience, production changes, industry developments and various other considerations. The estimated costs related to product recalls based on a formal campaign soliciting return of that product are accrued at the time an obligation becomes probable and can be reasonably estimated. These estimates are adjusted from time to time based on facts and circumstances that impact the status of existing claims. Delphi has recognized its best estimate for its total aggregate warranty reserves, including product recall costs, across all of its operating segments as of September 30, 2017 . The Company estimates the reasonably possible amount to ultimately resolve all matters in excess of the recorded reserves as of September 30, 2017 to be zero to $30 million . The table below summarizes the activity in the product warranty liability for the nine months ended September 30, 2017 : Warranty Obligations (in millions) Accrual balance at beginning of period $ 161 Provision for estimated warranties incurred during the period 64 Changes in estimate for pre-existing warranties 48 Settlements made during the period (in cash or in kind) (117 ) Foreign currency translation and other 9 Accrual balance at end of period $ 165 In September 2016, one of the Company's OEM customers initiated a recall to enhance airbag deployment systems in certain vehicles. Delphi's Electronics and Safety segment had supplied sensors and related control modules for the airbags in the affected vehicles. During the first quarter of 2017, Delphi reached an agreement with its customer related to this matter. In addition to the Company's previously recorded reserve estimate, Delphi recognized an incremental $43 million of warranty expense within cost of sales during the nine months ended September 30, 2017 related to this matter.

Restructuring

Restructuring and Related Activities [Abstract]
Restructuring	RESTRUCTURING Delphi’s restructuring activities are undertaken as necessary to implement management’s strategy, streamline operations, take advantage of available capacity and resources, and ultimately achieve net cost reductions. These activities generally relate to the realignment of existing manufacturing capacity and closure of facilities and other exit or disposal activities, as they relate to executing Delphi’s strategy, either in the normal course of business or pursuant to significant restructuring programs. As part of Delphi's continued efforts to optimize its cost structure, it has undertaken several restructuring programs which include workforce reductions as well as plant closures. These programs are primarily focused on the continued rotation of our manufacturing footprint to best cost locations in Europe and on reducing global overhead costs, including programs implemented to realign the Company's organizational structure due to changes in roles and workforce as a result of the planned spin-off of the Powertrain Systems segment. The Company recorded employee-related and other restructuring charges related to these programs totaling approximately $21 million and $180 million during the three and nine months ended September 30, 2017 , respectively. Restructuring costs recorded during the three months ended September 30, 2017 included $9 million for programs focused on the continued rotation of our manufacturing footprint to best cost locations in Europe, as well as $6 million for programs implemented to reduce global overhead costs. The charges recorded during the nine months ended September 30, 2017 included the recognition of approximately $54 million of employee-related and other costs related to the initiation of the closure of a Western European manufacturing site within the Powertrain Systems segment pursuant to the Company's on-going European footprint rotation strategy. Cash payments for this restructuring action are expected to be principally completed by 2020 . The charges recorded during the nine months ended September 30, 2017 also included $36 million of costs related to the closure of an Electronics and Safety Western European manufacturing site. Restructuring costs of approximately $63 million and $252 million were recorded during the three and nine months ended September 30, 2016 , respectively. These charges included $50 million recorded during the three months ended September 30, 2016 for programs implemented to reduce global overhead costs, as well as $152 million recorded during the nine months ended September 30, 2016 for programs focused on the continued rotation of our manufacturing footprint to low cost locations in Europe, $90 million of which related to the initiation of the closure of a European manufacturing site within the Powertrain Systems segment. Cash payments for this restructuring action are expected to be principally completed in 2017 . Additionally, Delphi recognized non-cash asset impairment charges of $19 million during the nine months ended September 30, 2016 related to this plant closure, which were recorded within cost of sales. Restructuring charges for employee separation and termination benefits are paid either over the severance period or in a lump sum in accordance with either statutory requirements or individual agreements. Delphi incurred cash expenditures related to its restructuring programs of approximately $162 million and $179 million in the nine months ended September 30, 2017 and 2016 , respectively. The following table summarizes the restructuring charges recorded for the three and nine months ended September 30, 2017 and 2016 by operating segment: Three Months Ended September 30, Nine Months Ended September 30, 2017 2016 2017 2016 (in millions) Electrical/Electronic Architecture $ 17 $ 30 $ 43 $ 65 Powertrain Systems 4 22 81 157 Electronics and Safety — 11 56 30 Total $ 21 $ 63 $ 180 $ 252 The table below summarizes the activity in the restructuring liability for the nine months ended September 30, 2017 : Employee Termination Benefits Liability Other Exit Costs Liability Total (in millions) Accrual balance at January 1, 2017 $ 193 $ 5 $ 198 Provision for estimated expenses incurred during the period 180 — 180 Payments made during the period (159 ) (3 ) (162 ) Foreign currency and other 22 (1 ) 21 Accrual balance at September 30, 2017 $ 236 $ 1 $ 237

The Credit Agreement was entered into in March 2011 and has been subsequently amended and restated on several occasions, most recently on August 17, 2016. The 2016 amendment extended the maturity of the Revolving Credit Facility and the Tranche A Term Loan from 2018 to 2021, increased the capacity of the Revolving Credit Facility from $1.5 billion to $2.0 billion and permitted Delphi Automotive PLC to act as a borrower on the Revolving Credit Facility. A loss on debt extinguishment of $3 million was recorded within other income (expense), net in the consolidated statement of operations during the third quarter of 2016 in conjunction with the 2016 amendment. The Tranche A Term Loan and the Revolving Credit Facility mature on August 17, 2021. Delphi is obligated to make quarterly principal payments, beginning December 31, 2017, throughout the term of the Tranche A Term Loan according to the amortization schedule in the Credit Agreement. The Credit Agreement also contains an accordion feature that permits Delphi to increase, from time to time, the aggregate borrowing capacity under the Credit Agreement by up to an additional $1 billion (or a greater amount based upon a formula set forth in the Credit Agreement) upon Delphi's request, the agreement of the lenders participating in the increase, and the approval of the Administrative Agent and existing lenders. As of September 30, 2017 , there were no amounts drawn on the Revolving Credit Facility and approximately $7 million in letters of credit issued under the Credit Agreement. Letters of credit issued under the Credit Agreement reduce availability under the Revolving Credit Facility. Loans under the Credit Agreement bear interest, at Delphi's option, at either (a) the Administrative Agent’s Alternate Base Rate (“ABR” as defined in the Credit Agreement) or (b) the London Interbank Offered Rate (the “Adjusted LIBO Rate” as defined in the Credit Agreement) (“LIBOR”) plus in either case a percentage per annum as set forth in the table below (the “Applicable Rate”). The Applicable Rates under the Credit Agreement on the specified dates are set forth below: September 30, 2017 December 31, 2016 LIBOR plus ABR plus LIBOR plus ABR plus Revolving Credit Facility 1.10 % 0.10 % 1.10 % 0.10 % Tranche A Term Loan 1.25 % 0.25 % 1.25 % 0.25 % The Applicable Rate under the Credit Agreement may increase or decrease from time to time based on changes in the Company's credit ratings. Accordingly, the interest rate will fluctuate during the term of the Credit Agreement based on changes in the ABR, LIBOR or future changes in the Company's corporate credit ratings. The Credit Agreement also requires that Delphi pay certain facility fees on the Revolving Credit Facility and certain letter of credit issuance and fronting fees. The interest rate period with respect to LIBOR interest rate options can be set at one-, two-, three-, or six-months as selected by Delphi in accordance with the terms of the Credit Agreement (or other period as may be agreed by the applicable lenders). Delphi may elect to change the selected interest rate option in accordance with the provisions of the Credit Agreement. As of September 30, 2017 , Delphi selected the one-month LIBOR interest rate option on the Tranche A Term Loan, and the rate effective as of September 30, 2017 , as detailed in the table below, was based on the Company's current credit rating and the Applicable Rate for the Credit Agreement: Borrowings as of September 30, 2017 Rate effective as of Applicable Rate (in millions) September 30, 2017 Tranche A Term Loan LIBOR plus 1.25% $ 400 2.50 % Borrowings under the Credit Agreement are prepayable at Delphi's option without premium or penalty. The Credit Agreement contains certain covenants that limit, among other things, the Company’s (and the Company’s subsidiaries’) ability to incur certain additional indebtedness or liens or to dispose of substantially all of its assets. In addition, the Credit Agreement requires that the Company maintain a consolidated leverage ratio (the ratio of Consolidated Total Indebtedness to Consolidated EBITDA, each as defined in the Credit Agreement) of less than 3.50 to 1.0 . The Credit Agreement also contains events of default customary for financings of this type. The Company was in compliance with the Credit Agreement covenants as of September 30, 2017 . As of September 30, 2017 , all obligations under the Credit Agreement were borrowed by Delphi Corporation and jointly and severally guaranteed by its direct and indirect parent companies, subject to certain exceptions set forth in the Credit Agreement. Refer to Note 19. Supplemental Guarantor and Non-Guarantor Condensed Consolidating Financial Statements for additional information. Senior Unsecured Notes On February 14, 2013, Delphi Corporation issued $800 million of 5.00% senior unsecured notes due 2023 (the “2013 Senior Notes”) in a transaction registered under Rule 144A and Regulation S of the Securities Act of 1933 (the “Securities Act”). The proceeds were primarily utilized to prepay our term loan indebtedness under the Credit Agreement. Delphi paid approximately $12 million of issuance costs in connection with the 2013 Senior Notes. Interest was payable semi-annually on February 15 and August 15 of each year to holders of record at the close of business on February 1 or August 1 immediately preceding the interest payment date. In September 2016, Delphi redeemed for cash the entire $800 million aggregate principal amount outstanding of the 2013 Senior Notes, primarily financed by the proceeds from the issuance of the 2016 Euro-denominated Senior Notes and the 2016 Senior Notes, each as defined below. As a result of the redemption of the 2013 Senior Notes, Delphi recognized a loss on debt extinguishment of approximately $70 million during the third quarter of 2016 within other income (expense), net in the consolidated statement of operations. On March 3, 2014, Delphi Corporation issued $700 million in aggregate principal amount of 4.15% senior unsecured notes due 2024 (the “2014 Senior Notes”) in a transaction registered under the Securities Act. The 2014 Senior Notes were priced at 99.649% of par, resulting in a yield to maturity of 4.193% . The proceeds were primarily utilized to redeem $500 million of 5.875% senior unsecured notes due 2019 and to repay a portion of the Tranche A Term Loan. Delphi paid approximately $6 million of issuance costs in connection with the 2014 Senior Notes. Interest is payable semi-annually on March 15 and September 15 of each year to holders of record at the close of business on March 1 or September 1 immediately preceding the interest payment date. On March 10, 2015, Delphi Automotive PLC issued €700 million in aggregate principal amount of 1.50% Euro-denominated senior unsecured notes due 2025 (the “2015 Euro-denominated Senior Notes”) in a transaction registered under the Securities Act. The 2015 Euro-denominated Senior Notes were priced at 99.54% of par, resulting in a yield to maturity of 1.55% . The proceeds were primarily utilized to redeem $500 million of 6.125% senior unsecured notes due 2021 , and to fund growth initiatives, such as acquisitions, and share repurchases. Delphi incurred approximately $5 million of issuance costs in connection with the 2015 Euro-denominated Senior Notes. Interest is payable annually on March 10. The Company has designated the 2015 Euro-denominated Senior Notes as a net investment hedge of the foreign currency exposure of its investments in certain Euro-denominated wholly-owned subsidiaries. Refer to Note. 14. Derivatives and Hedging Activities for further information. On November 19, 2015, Delphi Automotive PLC issued $1.3 billion in aggregate principal amount of senior unsecured notes in a transaction registered under the Securities Act, comprised of $650 million of 3.15% senior unsecured notes due 2020 (the "3.15% Senior Notes") and $650 million of 4.25% senior unsecured notes due 2026 (the "4.25% Senior Notes") (collectively, the "2015 Senior Notes"). The 3.15% Senior Notes were priced at 99.784% of par, resulting in a yield to maturity of 3.197% , and the 4.25% Senior Notes were priced at 99.942% of par, resulting in a yield to maturity of 4.256% . The proceeds were primarily utilized to fund a portion of the cash consideration for the acquisition of HellermannTyton, as further described in Note. 17. Acquisitions and Divestitures, and for general corporate purposes, including the payment of fees and expenses associated with the HellermannTyton acquisition and the related financing transaction. Delphi incurred approximately $8 million of issuance costs in connection with the 2015 Senior Notes. Interest on the 3.15% Senior Notes is payable semi-annually on May 19 and November 19 of each year to holders of record at the close of business on May 4 or November 4 immediately preceding the interest payment date. Interest on the 4.25% Senior Notes is payable semi-annually on January 15 and July 15 of each year to holders of record at the close of business on January 1 or July 1 immediately preceding the interest payment date. On September 15, 2016, Delphi Automotive PLC issued €500 million in aggregate principal amount of 1.60% Euro-denominated senior unsecured notes due 2028 (the “2016 Euro-denominated Senior Notes”) in a transaction registered under the Securities Act. The 2016 Euro-denominated Senior Notes were priced at 99.881% of par, resulting in a yield to maturity of 1.611% . The proceeds, together with proceeds from the 2016 Senior Notes described below, were utilized to redeem the 2013 Senior Notes. Delphi incurred approximately $4 million of issuance costs in connection with the 2016 Euro-denominated Senior Notes. Interest is payable annually on September 15. The Company has designated the 2016 Euro-denominated Senior Notes as a net investment hedge of the foreign currency exposure of its investments in certain Euro-denominated wholly-owned subsidiaries. Refer to Note. 14. Derivatives and Hedging Activities for further information. On September 20, 2016, Delphi Automotive PLC issued $300 million in aggregate principal amount of 4.40% senior unsecured notes due 2046 (the “2016 Senior Notes”) in a transaction registered under the Securities Act. The 2016 Senior Notes were priced at 99.454% of par, resulting in a yield to maturity of 4.433% . The proceeds, together with proceeds from the 2016 Euro-denominated Senior Notes, were utilized to redeem the 2013 Senior Notes. Delphi incurred approximately $3 million of issuance costs in connection with the 2016 Senior Notes. Interest is payable semi-annually on April 1 and October 1 of each year to holders of record at the close of business on March 15 or September 15 immediately preceding the interest payment date. Although the specific terms of each indenture governing each series of senior notes vary, the indentures contain certain restrictive covenants, including with respect to Delphi's (and Delphi's subsidiaries) ability to incur liens, enter into sale and leaseback transactions and merge with or into other entities. As of September 30, 2017 , the Company was in compliance with the provisions of all series of the outstanding senior notes. The 2013 Senior Notes and the 2014 Senior Notes were issued by Delphi Corporation. The 2014 Senior Notes are, and prior to their redemption, the 2013 Senior Notes were, fully and unconditionally guaranteed, jointly and severally, by Delphi Automotive PLC and by certain of Delphi Automotive PLC's direct and indirect subsidiaries which are directly or indirectly 100% owned by Delphi Automotive PLC, subject to customary release provisions (other than in the case of Delphi Automotive PLC). The 2015 Euro-denominated Senior Notes, 2015 Senior Notes, 2016 Euro-denominated Senior Notes and 2016 Senior Notes issued by Delphi Automotive PLC are fully and unconditionally guaranteed, jointly and severally, by certain of Delphi Automotive PLC's direct and indirect subsidiaries (including Delphi Corporation), which are directly or indirectly 100% owned by Delphi Automotive PLC, subject to customary release provisions. Refer to Note 19. Supplemental Guarantor and Non-Guarantor Condensed Consolidating Financial Statements for additional information. Spin-off Financing Delphi Technologies PLC ("Delphi Technologies"), a wholly owned subsidiary of the Company, was formed in connection with the Separation as a holding company to directly or indirectly own substantially all of the operating subsidiaries of the spin-off, to issue debt and to perform treasury operations of the spin-off, which prior to October 10, 2017 was named Delphi Jersey Holdings plc. Delphi Powertrain Corporation ("DPC"), a wholly owned U.S. subsidiary of the Company that will become a wholly owned subsidiary of Delphi Technologies PLC upon completion of the Separation, was also formed for the same purposes. Spin-off Credit Agreement On September 7, 2017, Delphi Technologies PLC and DPC entered into a credit agreement (the "Spin-Off Credit Agreement") with JPMorgan Chase Bank, N.A., as administrative agent, with respect to $1.25 billion in senior secured credit facilities. The Credit Agreement consists of a senior secured five-year $750 million term loan facility (the “Spin-Off Term Loan A Facility”) and a $500 million five-year senior secured revolving credit facility (the “ Spin-Off Revolving Credit Facility”) (collectively, the “Spin-Off Credit Facilities”) with the lenders party thereto and JPMorgan Chase Bank, N.A. The Spin-Off Credit Facilities are expected to become available to Delphi Technologies PLC no later than the date of the Separation, subject to the satisfaction of certain conditions customary for financings of this type, including the spin-off. Accordingly, no amounts were drawn or available to be drawn under the Spin-Off Credit Facilities as of September 30, 2017 . Prior to the date of the Separation, Delphi Technologies PLC is required to pay a 0.30% per annum commitment fee on the committed loans under the Spin-Off Credit Facilities. The Company incurred approximately $9 million of debt issuance costs in connection with the Spin-Off Credit Agreement. The borrowers under the Spin-Off Credit Agreement will comprise Delphi Technologies PLC and DPC. Additional subsidiaries of Delphi Technologies PLC may be added as co-borrowers or guarantors under the Spin-Off Credit Agreement from time to time on the terms and conditions set forth in the Spin-Off Credit Agreement. The obligations of each borrower under the Spin-Off Credit Agreement will be jointly and severally guaranteed by each other borrower and by certain of Delphi Technologies PLC's existing and future direct and indirect subsidiaries, subject to certain exceptions customary for financings of this type. All obligations of the borrowers and the guarantors will be secured by certain assets of such borrowers and guarantors, including a perfected first-priority pledge of all of the capital stock in DPC. Spin-Off Senior Notes On September 28, 2017, Delphi Technologies PLC issued $800 million in aggregate principal amount of 5.00% senior unsecured notes due 2025 in a transaction exempt from registration under the Securities Act (the "Spin-Off Senior Notes"). The Spin-Off Senior Notes were priced at 99.50% of par, resulting in a yield to maturity of 5.077% . Approximately $14 million of issuance costs were incurred in connection with the Spin-Off Senior Notes offering. Interest is payable semi-annually on April 1 and October 1 of each year to holders of record at the close of business on March 15 or September 15 immediately preceding the interest payment date. The proceeds received from the Spin-Off Senior Notes offering were deposited into escrow for release to Delphi Technologies PLC upon satisfaction of certain conditions, including completion of the Separation. If the conditions for the release of the proceeds of this offering from escrow are not satisfied by June 30, 2018, the Spin-Off Senior Notes will be subject to mandatory redemption. The Spin-Off Senior Notes have not been, and are not expected to be, guaranteed by the Company or any of its subsidiaries that will not be subsidiaries of Delphi Technologies PLC following the spin-off. Upon completion of the Separation, Delphi Technologies PLC will use the proceeds from the Spin-Off Senior Notes together with the proceeds from the Spin-Off Term Loan A Facility to fund a dividend to the Company, fund operating cash and pay taxes and related fees and expenses. Other Financing Receivable factoring —Delphi maintains a €400 million European accounts receivable factoring facility which is available on a non-committed basis. This facility is accounted for as short-term debt and borrowings are subject to the availability of eligible accounts receivable. Collateral is not required related to these trade accounts receivable. This program automatically renews on a non-committed, indefinite basis unless terminated by either party. Borrowings bear interest at LIBOR plus 1.05% for borrowings denominated in pounds sterling and Euro Interbank Offered Rate ("EURIBOR") plus 0.80% for borrowings denominated in Euros. No amounts were outstanding on the European accounts receivable factoring facility as of September 30, 2017 or December 31, 2016 . The Company has entered into arrangements with various financial institutions to sell eligible trade receivables from certain aftermarket customers in North America. These arrangements can be terminated at any time subject to prior written notice. The receivables under these arrangements are sold without recourse to the Company and are therefore accounted for as true sales. During the three and nine months ended September 30, 2017 , $25 million and $63 million of receivables were sold under these arrangements, and expenses of $1 million and $2 million , respectively, were recognized within interest expense. During the three and nine months ended September 30, 2016 , $19 million and $94 million of receivables were sold under these arrangements, and expenses of less than $1 million and $2 million , respectively, were recognized within interest expense. Capital leases and other —As of September 30, 2017 and December 31, 2016 , approximately $38 million and $42 million , respectively, of other debt issued by certain non-U.S. subsidiaries and capital lease obligations was outstanding. Interest —Cash paid for interest related to debt outstanding totaled $109 million and $131 million for the nine months ended September 30, 2017 and 2016 , respectively.

Pension Benefits

Retirement Benefits [Abstract]
Pension Benefits	PENSION BENEFITS Certain of Delphi’s non-U.S. subsidiaries sponsor defined benefit pension plans, which generally provide benefits based on negotiated amounts for each year of service. Delphi’s primary non-U.S. plans are located in France, Germany, Mexico, Portugal and the United Kingdom (“U.K.”). The U.K. and certain Mexican plans are funded. In addition, Delphi has defined benefit plans in South Korea, Turkey and Italy for which amounts are payable to employees immediately upon separation. The obligations for these plans are recorded over the requisite service period. Delphi sponsors a Supplemental Executive Retirement Program (“SERP”) for those employees who were U.S. executives of the former Delphi Corporation (now known as DPH Holdings Corp. (“DPHH”)) prior to September 30, 2008 and were still U.S. executives of Delphi on October 7, 2009, the effective date of the program. This program is unfunded. Executives receive benefits over 5 years after an involuntary or voluntary separation from Delphi. The SERP is closed to new members. The amounts shown below reflect the defined benefit pension expense for the three and nine months ended September 30, 2017 and 2016 : Non-U.S. Plans U.S. Plans Three Months Ended September 30, 2017 2016 2017 2016 (in millions) Service cost $ 13 $ 12 $ — $ — Interest cost 16 17 — — Expected return on plan assets (19 ) (18 ) — — Curtailment loss 1 — — — Amortization of actuarial losses 11 4 — — Net periodic benefit cost $ 22 $ 15 $ — $ — Non-U.S. Plans U.S. Plans Nine Months Ended September 30, 2017 2016 2017 2016 (in millions) Service cost $ 40 $ 37 $ — $ — Interest cost 45 51 1 1 Expected return on plan assets (54 ) (54 ) — — Curtailment loss 4 — — — Amortization of actuarial losses 29 11 — — Net periodic benefit cost $ 64 $ 45 $ 1 $ 1 As described in Note 2. Significant Accounting Policies, during the first quarter of 2017, the Company elected to early adopt ASU 2017-07. As a result, service costs are classified as employee compensation costs within cost of sales and selling, general and administrative expense within the consolidated statement of operations. All other components of net periodic benefit cost are classified within other expense for all periods presented. Other postretirement benefit obligations were approximately $5 million and $5 million at September 30, 2017 and December 31, 2016 , respectively.

Commitments And Contingencies

Commitments and Contingencies Disclosure [Abstract]
Commitments And Contingencies	COMMITMENTS AND CONTINGENCIES Ordinary Business Litigation Delphi is from time to time subject to various legal actions and claims incidental to its business, including those arising out of alleged defects, alleged breaches of contracts, product warranties, intellectual property matters, and employment-related matters. It is the opinion of Delphi that the outcome of such matters will not have a material adverse impact on the consolidated financial position, results of operations, or cash flows of Delphi. With respect to warranty matters, although Delphi cannot ensure that the future costs of warranty claims by customers will not be material, Delphi believes its established reserves are adequate to cover potential warranty settlements. Unsecured Creditors Litigation Delphi has been subject to ongoing litigation related to general unsecured claims against the former Delphi Corporation, now known as DPHH, resulting from that entity's 2005 bankruptcy filing. The Fourth Amended and Restated Limited Liability Partnership Agreement of Delphi Automotive LLP (the “Fourth LLP Agreement”) was entered into on July 12, 2011 by the members of Delphi Automotive LLP in order to position the Company for its initial public offering. Under the terms of the Fourth LLP Agreement, if cumulative distributions to the members of Delphi Automotive LLP under certain provisions of the Fourth LLP Agreement exceed $7.2 billion , Delphi, as disbursing agent on behalf of DPHH, is required to pay to the holders of allowed general unsecured claims against DPHH $32.50 for every $67.50 in excess of $7.2 billion distributed to the members, up to a maximum amount of $300 million . In December 2014, a complaint was filed in the United States Bankruptcy Court for the Southern District of New York (the "Bankruptcy Court") alleging that the 2011 redemption by Delphi Automotive LLP of the membership interests of GM and the Pension Benefit Guaranty Corporation (the "PBGC") totaling $4.4 billion, and the subsequent repurchase of shares and payment of dividends by Delphi Automotive PLC, constituted distributions under the terms of the Fourth LLP Agreement approximating $7.2 billion , triggering the maximum $300 million distribution to the holders of general unsecured claims. In May 2016, the Bankruptcy Court initially denied both parties' motions for summary judgment, requiring further submissions to the Bankruptcy Court regarding the parties' intent with respect to the redemptions of the GM and PBGC membership interests. On January 12, 2017, the Bankruptcy Court granted summary judgment in favor of the plaintiffs, ruling that the membership interest redemption payments qualified as distributions, which, along with share repurchases and dividend payments made by Delphi, count toward the $7.2 billion threshold, and thus the $300 million maximum distribution for general unsecured claims has been triggered. In connection with the January 2017 ruling, the Company recorded a reserve of $300 million in the fourth quarter of 2016. The reserve was recorded to other expense in the consolidated statement of operations, and resulted in a corresponding reduction in earnings per diluted share of approximately $1.10 for the year ended December 31, 2016. In March 2017, the Bankruptcy Court issued a ruling on the application of pre-judgment interest owed on the amount of the distribution to be made to the holders of general unsecured claims. Pursuant to this ruling, Delphi recorded an additional reserve of $27 million during the three months ended March 31, 2017. During the three months ended June 30, 2017, Delphi and the plaintiffs reached an agreement to settle this matter for $310 million , which was subsequently approved by the Bankruptcy Court. In accordance with the terms of the settlement agreement, the Company recorded a net incremental charge of $10 million to other expense during the nine months ended September 30, 2017 . In July 2017, the Company paid the $310 million settlement pursuant to the terms of the settlement agreement. Brazil Matters Delphi conducts business operations in Brazil that are subject to the Brazilian federal labor, social security, environmental, tax and customs laws, as well as a variety of state and local laws. While Delphi believes it complies with such laws, they are complex, subject to varying interpretations, and the Company is often engaged in litigation with government agencies regarding the application of these laws to particular circumstances. As of September 30, 2017 , the majority of claims asserted against Delphi in Brazil relate to such litigation. The remaining claims in Brazil relate to commercial and labor litigation with private parties. As of September 30, 2017 , claims totaling approximately $215 million (using September 30, 2017 foreign currency rates) have been asserted against Delphi in Brazil. As of September 30, 2017 , the Company maintains accruals for these asserted claims of $30 million (using September 30, 2017 foreign currency rates). The amounts accrued represent claims that are deemed probable of loss and are reasonably estimable based on the Company’s analyses and assessment of the asserted claims and prior experience with similar matters. While the Company believes its accruals are adequate, the final amounts required to resolve these matters could differ materially from the Company’s recorded estimates and Delphi’s results of operations could be materially affected. The Company estimates the reasonably possible loss in excess of the amounts accrued related to these claims to be zero to $185 million . Environmental Matters Delphi is subject to the requirements of U.S. federal, state, local and non-U.S. environmental and safety and health laws and regulations. As of September 30, 2017 and December 31, 2016 , the undiscounted reserve for environmental investigation and remediation was approximately $7 million (of which $2 million was recorded in accrued liabilities and $5 million was recorded in other long-term liabilities) and $6 million (of which $1 million was recorded in accrued liabilities and $5 million was recorded in other long-term liabilities), respectively. Delphi cannot ensure that environmental requirements will not change or become more stringent over time or that its eventual environmental remediation costs and liabilities will not exceed the amount of its current reserves. In the event that such liabilities were to significantly exceed the amounts recorded, Delphi’s results of operations could be materially affected. At September 30, 2017 , the difference between the recorded liabilities and the reasonably possible range of potential loss was not material.

Income Taxes

Income Tax Disclosure [Abstract]
Income Taxes	INCOME TAXES At the end of each interim period, the Company makes its best estimate of the annual expected effective income tax rate and applies that rate to its ordinary year-to-date earnings or loss. The income tax provision or benefit related to unusual or infrequent items, if applicable, that will be separately reported or reported net of their related tax effects are individually computed and recognized in the interim period in which those items occur. In addition, the effect of changes in enacted tax laws or rates, tax status, judgment on the realizability of a beginning-of-the-year deferred tax asset in future years or income tax contingencies is recognized in the interim period in which the change occurs. The computation of the annual expected effective income tax rate at each interim period requires certain estimates and assumptions including, but not limited to, the expected pre-tax income (or loss) for the year, projections of the proportion of income (and/or loss) earned and taxed in respective jurisdictions, permanent and temporary differences, and the likelihood of the realizability of deferred tax assets generated in the current year. Jurisdictions with a projected loss for the year or a year-to-date loss for which no tax benefit or expense can be recognized due to a valuation allowance are excluded from the estimated annual effective tax rate. The impact of such an exclusion could result in a higher or lower effective tax rate during a particular quarter, based upon the composition and timing of actual earnings compared to annual projections. The estimates used to compute the provision or benefit for income taxes may change as new events occur, additional information is obtained or as our tax environment changes. To the extent that the expected annual effective income tax rate changes, the effect of the change on prior interim periods is included in the income tax provision in the period in which the change in estimate occurs. The Company's income tax expense and effective tax rate for the three and nine months ended September 30, 2017 and 2016 were as follows: Three Months Ended September 30, Nine Months Ended September 30, 2017 2016 2017 2016 (dollars in millions) Income tax expense $ 60 $ 57 $ 183 $ 216 Effective tax rate 13 % 16 % 14 % 20 % The Company’s tax rate is affected by the fact that its parent entity is a U.K. resident taxpayer, the tax rates in the U.K. and other jurisdictions in which the Company operates, the relative amount of income earned by jurisdiction and the relative amount of losses or income for which no tax benefit or expense was recognized due to a valuation allowance. The Company’s effective tax rate was impacted by favorable changes in geographic income mix in 2017 as compared to 2016 primarily due to changes in the underlying business operations, the receipt of certain tax incentives and holidays that reduced the effective tax rate for certain subsidiaries below the statutory rate and the impact of losses recorded during the nine months ended September 30, 2016 in foreign jurisdictions for which no tax benefit was recognized due to a valuation allowance. The Company’s effective tax rate for the three months ended September 30, 2017 also includes net discrete tax benefits of $11 million primarily related to changes in reserves and provision to return adjustments. The Company’s effective tax rate for the nine months ended September 30, 2017 includes net discrete tax benefits of $22 million primarily related to provision to return adjustments, net of related changes in valuation allowances and reserves. The effective tax rate for the three and nine months ended September 30, 2016 includes net discrete tax benefits of $4 million and $3 million , respectively, primarily related to provision to return adjustments. Delphi Automotive PLC is a U.K. resident taxpayer and not a domestic corporation for U.S. federal income tax purposes, and as such is not subject to U.S. tax, and generally not subject to U.K. tax on remitted foreign earnings. Cash paid or withheld for income taxes was $199 million and $233 million for the nine months ended September 30, 2017 and 2016 respectively.

Shareholders' Equity and Net Income Per Share Note [Abstract]
Shareholders' Equity And Net Income Per Share	SHAREHOLDERS’ EQUITY AND NET INCOME PER SHARE Net Income Per Share Basic net income per share is computed by dividing net income attributable to Delphi by the weighted average number of ordinary shares outstanding during the period. Diluted net income per share reflects the weighted average dilutive impact of all potentially dilutive securities from the date of issuance and is computed using the treasury stock method by dividing net income attributable to Delphi by the diluted weighted average number of ordinary shares outstanding. For all periods presented, the calculation of diluted net income per share contemplates the dilutive impacts, if any, of the Company’s share-based compensation plans. Refer to Note 18. Share-Based Compensation for additional information. Weighted Average Shares The following table illustrates net income per share attributable to Delphi and the weighted average shares outstanding used in calculating basic and diluted income per share: Three Months Ended September 30, Nine Months Ended September 30, 2017 2016 2017 2016 (in millions, except per share data) Numerator: Income from continuing operations $ 395 $ 293 $ 1,099 $ 871 Income from discontinued operations — — — 105 Net income attributable to Delphi $ 395 $ 293 $ 1,099 $ 976 Denominator: Weighted average ordinary shares outstanding, basic 266.24 272.19 267.60 273.91 Dilutive shares related to restricted stock units ("RSUs") 0.92 0.58 0.63 0.48 Weighted average ordinary shares outstanding, including dilutive shares 267.16 272.77 268.23 274.39 Basic net income per share: Continuing operations $ 1.48 $ 1.08 $ 4.11 $ 3.18 Discontinued operations — — — 0.38 Basic net income per share attributable to Delphi $ 1.48 $ 1.08 $ 4.11 $ 3.56 Diluted net income per share: Continuing operations $ 1.48 $ 1.07 $ 4.10 $ 3.18 Discontinued operations — — — 0.38 Diluted net income per share attributable to Delphi $ 1.48 $ 1.07 $ 4.10 $ 3.56 Anti-dilutive securities share impact — — — — Share Repurchase Program In April 2016, the Board of Directors authorized a share repurchase program of up to $1.5 billion of ordinary shares, which commenced in September 2016 following the completion of the Company's $1.5 billion January 2015 share repurchase program. This share repurchase program provides for share purchases in the open market or in privately negotiated transactions, depending on share price, market conditions and other factors, as determined by the Company. A summary of the ordinary shares repurchased during the three and nine months ended September 30, 2017 and 2016 is as follows: Three Months Ended September 30, Nine Months Ended September 30, 2017 2016 2017 2016 Total number of shares repurchased 1,018,930 1,487,900 4,667,193 7,980,325 Average price paid per share $ 92.99 $ 67.24 $ 82.00 $ 67.00 Total (in millions) $ 95 $ 100 $ 383 $ 535 As of September 30, 2017 , approximately $989 million of share repurchases remained available under the April 2016 share repurchase program. All repurchased shares were retired, and are reflected as a reduction of ordinary share capital for the par value of the shares, with the excess applied as reductions to additional paid-in-capital and retained earnings. Dividends The Company has declared and paid cash dividends per ordinary share during the periods presented as follows: Dividend Amount Per Share (in millions) 2017: Third quarter $ 0.29 $ 77 Second quarter 0.29 78 First quarter 0.29 78 Total $ 0.87 $ 233 2016: Fourth quarter $ 0.29 $ 79 Third quarter 0.29 79 Second quarter 0.29 79 First quarter 0.29 80 Total $ 1.16 $ 317 In addition, in October 2017, the Board of Directors declared a regular quarterly cash dividend of $0.29 per ordinary share, payable November 22, 2017 to shareholders of record at the close of business on November 8, 2017. Other Prior to the completion of the initial public offering on November 22, 2011 , net income and other changes to membership interests were allocated to the respective outstanding classes based on the cumulative distribution provisions of the Fourth LLP Agreement. Under the terms of the Fourth LLP Agreement, if cumulative distributions to the members of Delphi Automotive LLP under certain provisions of the Fourth LLP Agreement exceed $7.2 billion , Delphi, as disbursing agent on behalf of DPHH, is required to pay to the holders of allowed general unsecured claims against DPHH $32.50 for every $67.50 in excess of $7.2 billion distributed to the members, up to a maximum amount of $300 million . As described in Note 10. Commitments and Contingencies, Delphi settled the litigation related to this matter during the nine months ended September 30, 2017.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Instruments and Hedging Activities	DERIVATIVES AND HEDGING ACTIVITIES Cash Flow Hedges Delphi is exposed to market risk, such as fluctuations in foreign currency exchange rates, commodity prices and changes in interest rates, which may result in cash flow risks. To manage the volatility relating to these exposures, Delphi aggregates the exposures on a consolidated basis to take advantage of natural offsets. For exposures that are not offset within its operations, Delphi enters into various derivative transactions pursuant to its risk management policies, which prohibit holding or issuing derivative financial instruments for speculative purposes, and designation of derivative instruments is performed on a transaction basis to support hedge accounting. The changes in fair value of these hedging instruments are offset in part or in whole by corresponding changes in the fair value or cash flows of the underlying exposures being hedged. Delphi assesses the initial and ongoing effectiveness of its hedging relationships in accordance with its documented policy. As of September 30, 2017 , the Company had the following outstanding notional amounts related to commodity and foreign currency forward and option contracts designated as cash flow hedges that were entered into to hedge forecasted exposures: Commodity Quantity Hedged Unit of Measure Notional Amount (in thousands) (in millions) Copper 57,124 pounds $ 170 Foreign Currency Quantity Hedged Unit of Measure Notional Amount (Approximate USD Equivalent) (in millions) Mexican Peso 16,872 MXN $ 925 Chinese Yuan Renminbi 2,410 RMB 365 Polish Zloty 344 PLN 95 New Turkish Lira 185 TRY 50 Hungarian Forint 4,025 HUF 15 The Company had additional foreign currency forward contracts designated as cash flow hedges with notional amounts that individually amounted to less than $10 million . As of September 30, 2017 , Delphi has entered into derivative instruments to hedge cash flows extending out to September 2019. Gains and losses on derivatives qualifying as cash flow hedges are recorded in accumulated other comprehensive income ("OCI"), to the extent that hedges are effective, until the underlying transactions are recognized in earnings. Unrealized amounts in accumulated OCI will fluctuate based on changes in the fair value of hedge derivative contracts at each reporting period. Net gains on cash flow hedges included in accumulated OCI as of September 30, 2017 were approximately $34 million (approximately $31 million , net of tax). Of this total, approximately $28 million are expected to be included in cost of sales within the next 12 months and $6 million are expected to be included in cost of sales in subsequent periods. Cash flow hedges are discontinued when Delphi determines it is no longer probable that the originally forecasted transactions will occur. The amount included in cost of sales related to cash flow hedge ineffectiveness was insignificant for the three and nine months ended September 30, 2017 and 2016 . Cash flows from derivatives used to manage commodity and foreign exchange risks are classified as operating activities within the consolidated statement of cash flows. Net Investment Hedges The Company is also exposed to the risk that adverse changes in foreign currency exchange rates could impact its net investment in non-U.S. subsidiaries. To manage this risk, the Company designates certain qualifying derivative and non-derivative instruments, including foreign currency forward contracts and foreign currency-denominated debt, as net investment hedges of certain non-U.S. subsidiaries. The effective portion of the gains or losses on instruments designated as net investment hedges are recognized within OCI to offset changes in the value of the net investment in these foreign currency-denominated operations. Any ineffective portion of gains or losses on net investment hedges are reclassified to other income (expense), net within the consolidated statement of operations. Gains and losses reported in accumulated other comprehensive income (loss) are reclassified to earnings only when the related currency translation adjustments are required to be reclassified, usually upon sale or liquidation of the investment. Cash flows from derivatives designated as net investment hedges are classified as investing activities within the consolidated statement of cash flows. During 2016 and 2017, the Company entered into a series of forward contracts, each of which were designated as net investment hedges of the foreign currency exposure of the Company's investments in certain Chinese Yuan Renminbi ("RMB")-denominated subsidiaries. During the first quarter of 2016, the Company entered into a forward contract with a notional amount of 2.4 billion RMB (approximately $370 million , using March 31, 2016 foreign currency rates), which matured in May 2016 , and the Company paid $1 million at settlement. In December 2016, the Company entered into a forward contract with a notional amount of 1.8 billion RMB (approximately $265 million , using December 31, 2016 foreign currency rates), which matured in June 2017 , and the Company paid $12 million at settlement. In June 2017, the Company entered into a forward contract with a notional amount of 2.4 billion RMB (approximately $345 million , using June 30, 2017 foreign currency rates), which matures in December 2017 . Refer to the tables below for details of the fair value recorded in the consolidated balance sheet and the effects recorded in the consolidated statement of operations and consolidated statement of comprehensive income related to these derivative instruments. The Company has designated the €700 million 2015 Euro-denominated Senior Notes and the €500 million 2016 Euro-denominated Senior Notes, as more fully described in Note 8. Debt, as net investment hedges of the foreign currency exposure of its investments in certain Euro-denominated subsidiaries. Due to changes in the value of the Euro-denominated debt instruments designated as net investment hedges, during the three and nine months ended September 30, 2017 , $44 million and $147 million , respectively, of losses were recognized within the cumulative translation adjustment component of OCI. During the three and nine months ended September 30, 2016 , $10 million and $19 million , respectively, of losses were recognized within the cumulative translation adjustment component of OCI. Cumulative (losses) gains included in accumulated OCI on these net investment hedges were $(87) million as of September 30, 2017 and $60 million as of December 31, 2016 . There were no amounts reclassified or recognized for ineffectiveness during the three and nine months ended September 30, 2017 or 2016 . Derivatives Not Designated as Hedges In certain occasions the Company enters into certain foreign currency and commodity contracts that are not designated as hedges. When hedge accounting is not applied to derivative contracts, gains and losses are recorded to other income (expense), net and cost of sales in the consolidated statement of operations. As more fully disclosed in Note 17. Acquisitions and Divestitures, on July 30, 2015, Delphi made a recommended offer to acquire HellermannTyton. In conjunction with the acquisition, in August 2015, the Company entered into option contracts with notional amounts totaling £917 million to hedge portions of the currency risk associated with the cash payment for the acquisition at a cost of $15 million . Subsequently, in conjunction with the closing of the acquisition, Delphi entered into offsetting option contracts. Pursuant to the requirements of ASC 815, Derivatives and Hedging , the options did not qualify as hedges for accounting purposes. The Company paid $15 million to settle these options during the nine months ended September 30, 2016 , which is reflected within investing activities in the consolidated statement of cash flows. Fair Value of Derivative Instruments in the Balance Sheet The fair value of derivative financial instruments recorded in the consolidated balance sheets as of September 30, 2017 and December 31, 2016 are as follows: Asset Derivatives Liability Derivatives Net Amounts of Assets and (Liabilities) Presented in the Balance Sheet Balance Sheet Location September 30, Balance Sheet Location September 30, September 30, (in millions) Derivatives designated as cash flow hedges: Commodity derivatives Other current assets $ 20 Accrued liabilities $ — Foreign currency derivatives* Other current assets 23 Other current assets 7 $ 16 Foreign currency derivatives* Accrued liabilities 2 Accrued liabilities 6 (4 ) Commodity derivatives Other long-term assets 5 Other long-term liabilities — Foreign currency derivatives* Other long-term assets 8 Other long-term assets 1 7 Foreign currency derivatives* Other long-term liabilities — Other long-term liabilities 3 (3 ) Derivatives designated as net investment hedges: Foreign currency derivatives Other current assets $ — Accrued liabilities $ 12 Total derivatives designated as hedges $ 58 $ 29 Asset Derivatives Liability Derivatives Net Amounts of Assets and (Liabilities) Presented in the Balance Sheet Balance Sheet Location December 31, Balance Sheet Location December 31, December 31, (in millions) Derivatives designated as cash flow hedges: Commodity derivatives Other current assets $ 7 Accrued liabilities $ — Foreign currency derivatives* Other current assets 6 Other current assets 3 $ 3 Foreign currency derivatives* Accrued liabilities 9 Accrued liabilities 55 (46 ) Commodity derivatives Other long-term assets 4 Other long-term liabilities — Foreign currency derivatives* Other long-term assets 8 Other long-term assets 4 4 Foreign currency derivatives* Other long-term liabilities — Other long-term liabilities 11 (11 ) Derivatives designated as net investment hedges: Foreign currency derivatives Other current assets $ 2 Accrued liabilities $ — Total derivatives designated as hedges $ 36 $ 73 Derivatives not designated: Foreign currency derivatives* Other current assets $ — Other current assets $ 1 (1 ) Foreign currency derivatives* Accrued liabilities 2 Accrued liabilities 1 1 Total derivatives not designated as hedges $ 2 $ 2 * Derivative instruments within this category are subject to master netting arrangements and are presented on a net basis in the consolidated balance sheets in accordance with accounting guidance related to the offsetting of amounts related to certain contracts. The fair value of Delphi’s derivative financial instruments was in a net asset position as of September 30, 2017 and a net liability position as of December 31, 2016 . Effect of Derivatives on the Statement of Operations and Statement of Comprehensive Income The pre-tax effect of derivative financial instruments in the consolidated statement of operations and consolidated statement of comprehensive income for the three months ended September 30, 2017 is as follows: Three Months Ended September 30, 2017 Gain (loss) Recognized in OCI (Effective Portion) Gain Reclassified from OCI into Income (Effective Portion) Gain Recognized in Income (Ineffective Portion Excluded from Effectiveness Testing) (in millions) Derivatives designated as cash flow hedges: Commodity derivatives $ 15 $ 5 $ — Foreign currency derivatives (13 ) 1 — Derivatives designated as net investment hedges: Foreign currency derivatives (10 ) — — Total $ (8 ) $ 6 $ — Gain Recognized in Income (in millions) Derivatives not designated: Commodity derivatives $ — Foreign currency derivatives — Total $ — The pre-tax effect of derivative financial instruments in the consolidated statement of operations and consolidated statement of comprehensive income for the three months ended September 30, 2016 is as follows: Three Months Ended September 30, 2016 Gain (loss) Recognized in OCI (Effective Portion) Loss Reclassified from OCI into Income (Effective Portion) Gain Recognized in Income (Ineffective Portion Excluded from Effectiveness Testing) (in millions) Derivatives designated as cash flow hedges: Commodity derivatives $ 1 $ (10 ) $ — Foreign currency derivatives (26 ) (20 ) — Derivatives designated as net investment hedges: Foreign currency derivatives (1 ) — — Total $ (26 ) $ (30 ) $ — Gain Recognized in Income (in millions) Derivatives not designated: Foreign currency derivatives $ 1 Total $ 1 The pre-tax effect of derivative financial instruments in the consolidated statement of operations and consolidated statement of comprehensive income for the nine months ended September 30, 2017 is as follows: Nine Months Ended September 30, 2017 Gain (loss) Recognized in OCI (Effective Portion) Gain (loss) Reclassified from OCI into Income (Effective Portion) Gain Recognized in Income (Ineffective Portion Excluded from Effectiveness Testing) (in millions) Derivatives designated as cash flow hedges: Commodity derivatives $ 26 $ 8 $ — Foreign currency derivatives 41 (26 ) — Derivatives designated as net investment hedges: Foreign currency derivatives (26 ) — — Total $ 41 $ (18 ) $ — Loss Recognized in Income (in millions) Derivatives not designated: Foreign currency derivatives $ (5 ) Total $ (5 ) The pre-tax effect of derivative financial instruments in the consolidated statement of operations and consolidated statement of comprehensive income for the nine months ended September 30, 2016 is as follows: Nine Months Ended September 30, 2016 Gain (loss) Recognized in OCI (Effective Portion) Loss Reclassified from OCI into Income (Effective Portion) Gain Recognized in Income (Ineffective Portion Excluded from Effectiveness Testing) (in millions) Derivatives designated as cash flow hedges: Commodity derivatives $ 5 $ (35 ) $ — Foreign currency derivatives (46 ) (65 ) — Derivatives designated as net investment hedges: Foreign currency derivatives 3 — — Total $ (38 ) $ (100 ) $ — Loss Recognized in Income (in millions) Derivatives not designated: Foreign currency derivatives $ (1 ) Total $ (1 ) The gain or loss reclassified from OCI into income for the effective portion of designated derivative instruments and the gain or loss recognized in income for the ineffective portion of designated derivative instruments excluded from effectiveness testing were recorded to other income, net and cost of sales in the consolidated statements of operations for the three and nine months ended September 30, 2017 and 2016 . The gain or loss recognized in income for non-designated derivative instruments was recorded in other income (expense), net and cost of sales for the three and nine months ended September 30, 2017 and 2016 .

Fair Value Of Financial Instrum

Fair Value Of Financial Instruments	9 Months Ended

Fair Value Disclosures [Abstract]
Fair Value of Financial Instruments	FAIR VALUE OF FINANCIAL INSTRUMENTS Fair Value Measurements on a Recurring Basis Derivative instruments —All derivative instruments are required to be reported on the balance sheet at fair value unless the transactions qualify and are designated as normal purchases or sales. Changes in fair value are reported currently through earnings unless they meet hedge accounting criteria. Delphi’s derivative exposures are with counterparties with long-term investment grade credit ratings. Delphi estimates the fair value of its derivative contracts using an income approach based on valuation techniques to convert future amounts to a single, discounted amount. Estimates of the fair value of foreign currency and commodity derivative instruments are determined using exchange traded prices and rates. Delphi also considers the risk of non-performance in the estimation of fair value, and includes an adjustment for non-performance risk in the measure of fair value of derivative instruments. The non-performance risk adjustment reflects the credit default spread (“CDS”) applied to the net commodity by counterparty and foreign currency exposures by counterparty. When Delphi is in a net derivative asset position, the counterparty CDS rates are applied to the net derivative asset position. When Delphi is in a net derivative liability position, estimates of peer companies’ CDS rates are applied to the net derivative liability position. In certain instances where market data is not available, Delphi uses management judgment to develop assumptions that are used to determine fair value. This could include situations of market illiquidity for a particular currency or commodity or where observable market data may be limited. In those situations, Delphi generally surveys investment banks and/or brokers and utilizes the surveyed prices and rates in estimating fair value. As of September 30, 2017 and December 31, 2016 , Delphi was in a net derivative asset (liability) position of $29 million and $(37) million , respectively, and no significant adjustments were recorded for nonperformance risk based on the application of peer companies’ CDS rates, evaluation of our own nonperformance risk and because Delphi’s exposures were to counterparties with investment grade credit ratings. Refer to Note 14. Derivatives and Hedging Activities for further information regarding derivatives. Contingent consideration —As described in Note 17. Acquisitions and Divestitures, as of September 30, 2017 , additional contingent consideration may be earned as a result of Delphi's acquisition agreements for Movimento Group ("Movimento"), Control-Tec LLC ("Control-Tec"), Ottomatika, Inc. ("Ottomatika") and Antaya Technologies Corporation ("Antaya"). The liability for contingent consideration is estimated as of the date of the acquisition and is recorded as part of the purchase price, and is subsequently re-measured to fair value at each reporting date, based on a probability-weighted discounted cash flow analysis using a rate that reflects the uncertainty surrounding the expected outcomes, which the Company believes is appropriate and representative of market participant assumptions. The measurement of the liability for contingent consideration is based on significant inputs that are not observable in the market, and is therefore classified as a Level 3 measurement in accordance with ASU Topic 820-10-35. Examples of utilized unobservable inputs are estimated future earnings of the acquired businesses and applicable discount rates. The estimate of the liability may fluctuate if there are changes in the forecast of the acquired businesses' future earnings, as a result of actual earnings levels achieved or in the discount rates used to determine the present value of contingent future cash flows. As of September 30, 2017 , the range of periods in which the earn-out provisions may be achieved is from 2017 to 2018 . The Company regularly reviews these assumptions and makes adjustments to the fair value measurements as required by facts and circumstances. As of September 30, 2017 and December 31, 2016 , the liability for contingent consideration was $22 million (of which $2 million was classified within other current liabilities and $20 million was classified within other long-term liabilities) and $35 million (of which was $22 million classified within other current liabilities and $13 million was classified within other long-term liabilities). Adjustments to this liability for interest accretion are recognized in interest expense, and any other changes in the fair value of this liability are recognized within other income (expense), net in the consolidated statement of operations. The changes in the contingent consideration liability classified as a Level 3 measurement for the nine months ended September 30, 2017 were as follows: Contingent Consideration Liability (in millions) Fair value at beginning of period $ 35 Additions 8 Payments (22 ) Interest accretion 1 Fair value at end of period $ 22 During the nine months ended September 30, 2017 , Delphi recorded a liability of $8 million for the estimated fair value of the contingent consideration for the acquisition of Movimento, as further described in Note 17. Acquisitions and Divestitures. Also during the nine months ended September 30, 2017 , Delphi paid $20 million of contingent consideration related to its 2015 acquisition of Control-Tec and $2 million of contingent consideration related to its 2015 acquisition of Ottomatika. As of September 30, 2017 and December 31, 2016 , Delphi had the following assets measured at fair value on a recurring basis: Total Quoted Prices in Active Markets Significant Other Observable Inputs Significant Unobservable Inputs (in millions) As of September 30, 2017 Commodity derivatives $ 25 $ — $ 25 $ — Foreign currency derivatives 23 — 23 — Total $ 48 $ — $ 48 $ — As of December 31, 2016: Commodity derivatives $ 11 $ — $ 11 $ — Foreign currency derivatives 8 — 8 — Total $ 19 $ — $ 19 $ — As of September 30, 2017 and December 31, 2016 , Delphi had the following liabilities measured at fair value on a recurring basis: Total Quoted Prices in Active Markets Significant Other Observable Inputs Significant Unobservable Inputs (in millions) As of September 30, 2017 Commodity derivatives $ — $ — $ — $ — Foreign currency derivatives 19 — 19 — Contingent consideration 22 — — 22 Total $ 41 $ — $ 19 $ 22 As of December 31, 2016: Foreign currency derivatives $ 56 $ — $ 56 $ — Contingent consideration 35 — — 35 Total $ 91 $ — $ 56 $ 35 Non-derivative financial instruments —Delphi’s non-derivative financial instruments include cash and cash equivalents, accounts and notes receivable, accounts payable, as well as debt, which consists of its accounts receivable factoring arrangements, capital leases and other debt issued by Delphi’s non-U.S. subsidiaries, the Revolving Credit Facility, the Tranche A Term Loan and all series of outstanding senior notes. The fair value of debt is based on quoted market prices for instruments with public market data or significant other observable inputs for instruments without a quoted public market price (Level 2). As of September 30, 2017 and December 31, 2016 , total debt was recorded at $4,899 million and $3,971 million , respectively, and had estimated fair values of $5,002 million and $4,007 million , respectively. For all other financial instruments recorded at September 30, 2017 and December 31, 2016 , fair value approximates book value. Fair Value Measurements on a Nonrecurring Basis In addition to items that are measured at fair value on a recurring basis, Delphi also has items in its balance sheet that are measured at fair value on a nonrecurring basis. As these items are not measured at fair value on a recurring basis, they are not included in the tables above. Nonfinancial assets and liabilities that are measured at fair value on a nonrecurring basis include certain long-lived assets, equity and cost method investments, intangible assets, asset retirement obligations, share-based compensation and liabilities for exit or disposal activities measured at fair value upon initial recognition. During the three and nine months ended September 30, 2017 , Delphi recorded non-cash asset impairment charges totaling $1 million and $10 million , respectively, within cost of sales related to declines in the fair values of certain fixed assets. During the three and nine months ended September 30, 2016 , Delphi recorded non-cash asset impairment charges totaling $1 million and $23 million , respectively, within cost of sales related to declines in the fair values of certain fixed assets, $19 million of which related to the initiation of a plant closure of a European manufacturing site within the Powertrain Systems segment in the second quarter of 2016, as further described in Note 7. Restructuring. Fair value of long-lived assets is determined primarily using the anticipated cash flows discounted at a rate commensurate with the risk involved and a review of appraisals. As such, Delphi has determined that the fair value measurements of long-lived assets fall in Level 3 of the fair value hierarchy.

Acquisitions and Divestitures	ACQUISITIONS AND DIVESTITURES Acquisition of nuTonomy On October 20, 2017, Delphi agreed to acquire nuTonomy, Inc. ("nuTonomy"), a leading provider of autonomous driving software and technology, for total consideration of up to $454 million . Of the total consideration, $290 million of purchase price is payable at closing, subject to certain post-closing adjustments, and approximately $110 million will vest to certain selling shareholders in annual installments over 3 years from the acquisition date, subject to those selling shareholders' compliance with certain service conditions. Of the $ 110 million , approximately $8 million is payable after one year and approximately $51 million is payable after each of the second and third years following the acquisition date. These remaining installments will be recorded as a component of Selling, general and administrative expense ratably over the respective installment period. Additionally, the total consideration includes a cash payment of up to $54 million contingent upon the achievement of certain performance metrics over a future 3 -year period. The acquisition is subject to the satisfaction of customary closing conditions and the receipt of regulatory and other approvals, and is expected to close in the fourth quarter of 2017. The Company intends to acquire nuTonomy utilizing cash on hand. Upon completion, nuTonomy will become part of Delphi’s Electronics and Safety segment. Acquisition of Movimento Group On January 3, 2017 , Delphi acquired 100% of the equity interests of Movimento Group ("Movimento"), a leading provider of Over-the-Air software and data management for the automotive sector, for a purchase price of $40 million at closing and an additional cash payment of up to $10 million contingent upon the achievement of certain performance metrics over a future 2 -year period.

The preliminary purchase price and related allocation to the acquired net assets of Movimento based on their estimated fair values is shown below (in millions): Assets acquired and liabilities assumed Purchase price, cash consideration, net of cash acquired $ 40 Purchase price, fair value of contingent consideration 8 Total purchase price, net of cash acquired $ 48 Intangible assets $ 22 Other assets, net 4 Identifiable net assets acquired 26 Goodwill resulting from purchase 22 Total purchase price allocation $ 48 Intangible assets include $8 million recognized for the fair value of the acquired trade name, which has an estimated useful life of approximately 25 years, $4 million of customer-based and technology-related assets with estimated useful lives of approximately 7 years, and $10 million of in-process research and development, which will not be amortized, but tested for impairment until the completion or abandonment of the associated research and development efforts. The estimated fair value of these assets was based on third-party valuations and management's estimates, generally utilizing income and market approaches. The purchase price and related allocation are preliminary and could be revised as a result of adjustments made to the purchase price, additional information obtained regarding liabilities assumed, including, but not limited to, contingent liabilities, revisions of provisional estimates of fair values, including, but not limited to, the completion of independent appraisals and valuations related to property, plant and equipment and intangible assets, and certain tax attributes. The pro forma effects of this acquisition would not materially impact the Company's reported results for any period presented, and as a result no pro forma financial statements were presented. Acquisition of PureDepth, Inc. On March 23, 2016 , Delphi acquired 100% of the equity interests of PureDepth, Inc. ("PureDepth"), a leading provider of 3D display technology, for approximately $15 million . The results of operations of PureDepth are reported within the Electronics and Safety segment from the date of acquisition. The acquisition was accounted for as a business combination, with the total purchase price allocated on a preliminary basis using information available, in the first quarter of 2016. The purchase price and related allocation were finalized in the first quarter of 2017, and resulted in no adjustments from the amounts previously disclosed. The purchase price and related allocation to the acquired net assets of PureDepth based on their estimated fair values is shown below (in millions): Assets acquired and liabilities assumed Purchase price, cash consideration $ 15 Intangible assets $ 10 Goodwill resulting from purchase 5 Total purchase price allocation $ 15 Intangible assets include amounts recognized for the fair value of in-process research and development, which will not be amortized, but tested for impairment until the completion or abandonment of the associated research and development efforts. The fair value of these assets was based on third-party valuations and management's estimates, generally utilizing income and market approaches. The pro forma effects of this acquisition would not materially impact the Company's reported results for any period presented, and as a result no pro forma financial statements were presented. Acquisition of HellermannTyton Group PLC On December 18, 2015 , pursuant to the terms of a recommended offer made on July 30, 2015 , Delphi completed the acquisition of 100% of the issued ordinary share capital of HellermannTyton Group PLC ("HellermannTyton"), a public limited company based in the United Kingdom, and a leading global manufacturer of high-performance and innovative cable management solutions. Delphi paid 480 pence per HellermannTyton share, totaling approximately $1.5 billion in aggregate, net of cash acquired. Approximately $242 million of HellermannTyton outstanding debt to third-party creditors was assumed and subsequently paid off. HellermannTyton had 2014 sales of approximately €600 million (approximately 6% of which were to Delphi and will be eliminated on a consolidated basis). Upon completing the acquisition, Delphi incurred transaction related expenses totaling approximately $23 million , which were recorded within other income (expense), net in the statement of operations in the fourth quarter of 2015. The acquisition was accounted for as a business combination, with the total purchase price allocated on a preliminary basis using information available, in the fourth quarter of 2015. The purchase price and related allocation were finalized in the fourth quarter of 2016. As a result of additional information obtained, changes to the preliminary fair values of certain property, plant and equipment, and other assets purchased and liabilities assumed, including contingent tax liabilities, from the amounts disclosed as of December 31, 2015 were recorded during the year ended December 31, 2016, which resulted in a net adjustment to goodwill of $10 million . These adjustments did not result in significant effects to the consolidated statement of operations for the year ended December 31, 2016. The purchase price and related allocation to the acquired net assets of HellermannTyton based on their estimated fair values is shown below (in millions): Assets acquired and liabilities assumed Purchase price, cash consideration, net of cash acquired $ 1,534 Debt and pension liabilities assumed 258 Total consideration, net of cash acquired $ 1,792 Property, plant and equipment $ 326 Indefinite-lived intangible assets 128 Definite-lived intangible assets 554 Other liabilities, net (82 ) Identifiable net assets acquired 926 Goodwill resulting from purchase 866 Total purchase price allocation $ 1,792 Goodwill recognized in this transaction is primarily attributable to synergies expected to arise after the acquisition and the assembled workforce of HellermannTyton, and is not deductible for tax purposes. Intangible assets primarily include $128 million recognized for the fair value of the acquired trade name, which has an indefinite useful life, $451 million of customer-based assets with approximate useful lives of 13 years and $103 million of technology-related assets with approximate useful lives of 13 years. The valuation of the intangible assets acquired was based on third-party valuations, management's estimates, available information and reasonable and supportable assumptions. The fair value of the acquired trade name and the technology-related assets was generally estimated utilizing the relief from royalty method under the income approach, and the fair value of customer-based assets was generally estimated utilizing the multi-period excess earnings method. The results of operations of HellermannTyton are reported within the Electrical/Electronic Architecture segment from the date of acquisition. The pro forma effects of this acquisition would not materially impact the Company's reported results for any period presented, and as a result no pro forma financial statements were presented. Acquisition financing Delphi financed the cash payment required to close the acquisition of HellermannTyton primarily with the net proceeds received from the offering of $1.3 billion of 2015 Senior Notes, as further described in Note 8. Debt, with the remainder of the purchase price funded with cash on hand that was received from the sale of the Company's Thermal Systems business, as further described below. Prior to the transaction closing, in connection with the offer to acquire HellermannTyton in July 2015, £540 million ( $844 million using July 30, 2015 foreign currency rates) was placed on deposit for purposes of satisfying a portion of the consideration required to effect the acquisition. Sale of Mechatronics Business On December 30, 2016, Delphi completed the sale of its Mechatronics business, which was previously reported within the Electronics and Safety segment, for net cash proceeds of approximately $197 million . The net sales of this business in 2016 prior to the divestiture were approximately $290 million . Delphi recognized a pre-tax gain on the divestiture of $141 million , net of $29 million of accumulated currency translation losses transferred from accumulated other comprehensive income, which is included in cost of sales in the consolidated statement of operations. The gain on the divestiture, net of tax, was $124 million , resulting in an increase in earnings per diluted share of approximately $0.45 for the year ended December 31, 2016. The results of operations of this business were not significant to the consolidated financial statements for any period presented, and the divestiture did not meet the discontinued operations criteria. Sale of Thermal Systems Business On June 30, 2015, Delphi completed the sale of the Company's wholly owned Thermal Systems business. On September 24, 2015, Delphi completed the sale of its interest in its KDAC joint venture, and on March 31, 2016, Delphi completed the sale of its interest in its SDAAC joint venture. Delphi's interests in the SDAAC and KDAC joint ventures were previously reported within the Thermal Systems segment. Accordingly, the results of the Thermal Systems business are classified as discontinued operations for all periods presented. Refer to Note 21. Discontinued Operations for further disclosure related to the Company's discontinued operations, including details of the divestiture transactions. Technology Investments The Company has made technology investments in certain non-consolidated affiliates for ownership interests of less than 20%, which are accounted for under the cost method.

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
Share-Based Compensation	SHARE-BASED COMPENSATION Long Term Incentive Plan The Delphi Automotive PLC Long-Term Incentive Plan, as amended and restated effective April 23, 2015 (the “PLC LTIP”), allows for the grant of awards of up to 22,977,116 ordinary shares for long-term compensation. The PLC LTIP is designed to align the interests of management and shareholders. The awards can be in the form of shares, options, stock appreciation rights, restricted stock, restricted stock units ("RSUs"), performance awards, and other share-based awards to the employees, directors, consultants and advisors of the Company. The Company has awarded annual long-term grants of RSUs under the PLC LTIP in each year from 2012 to 2017 in order to align management compensation with Delphi's overall business strategy. The Company has competitive and market-appropriate ownership requirements. All of the RSUs granted under the PLC LTIP are eligible to receive dividend equivalents for any dividend paid from the grant date through the vesting date. Dividend equivalents are generally paid out in ordinary shares upon vesting of the underlying RSUs. Historical amounts disclosed within this note include amounts attributable to the Company's discontinued operations, unless otherwise noted. Board of Director Awards On April 23, 2015, Delphi granted 20,347 RSUs to the Board of Directors at a grant date fair value of approximately $2 million . The grant date fair value was determined based on the closing price of the Company's ordinary shares on April 23, 2015. The RSUs vested on April 27, 2016, and 24,542 ordinary shares, which included shares issued in connection with dividend equivalents, were issued to members of the Board of Directors at a fair value of approximately $2 million . 1,843 ordinary shares were withheld to cover the minimum U.K. withholding taxes. On April 28, 2016, Delphi granted 27,238 RSUs to the Board of Directors at a grant date fair value of approximately $2 million . The grant date fair value was determined based on the closing price of the Company's ordinary shares on April 28, 2016. The RSUs vested on April 26, 2017, and 26,580 ordinary shares, which included shares issued in connection with dividend equivalents, were issued to members of the Board of Directors at a fair value of approximately $2 million . 3,472 ordinary shares were withheld to cover the minimum U.K. withholding taxes. On April 27, 2017, Delphi granted 26,782 RSUs to the Board of Directors at a grant date fair value of approximately $2 million . The grant date fair value was determined based on the closing price of the Company's ordinary shares on April 27, 2017. The RSUs will vest on April 25, 2018, the day before the 2018 annual meeting of shareholders. Executive Awards Delphi has made annual grants of RSUs to its executives in February of each year beginning in 2012. These awards include a time-based vesting portion and a performance-based vesting portion, as well as continuity awards in certain years. The time-based RSUs, which make up 25% of the awards for Delphi’s officers and 50% for Delphi’s other executives, vest ratably over three years beginning on the first anniversary of the grant date. The performance-based RSUs, which make up 75% of the awards for Delphi’s officers and 50% for Delphi’s other executives, vest at the completion of a three-year performance period if certain targets are met. Each executive will receive between 0% and 200% of his or her target performance-based award based on the Company’s performance against established company-wide performance metrics, which are: Metric 2016 - 2017 Grants 2013 - 2015 Grants Average return on net assets (1) 50% 50% Cumulative net income 25% N/A Cumulative earnings per share (2) N/A 30% Relative total shareholder return (3) 25% 20% (1) Average return on net assets is measured by tax-affected operating income divided by average net working capital plus average net property, plant and equipment for each calendar year during the respective performance period. (2) Cumulative earnings per share is measured by net income attributable to Delphi divided by the weighted average number of diluted shares outstanding for the respective three-year performance period. (3) Relative total shareholder return is measured by comparing the average closing price per share of the Company’s ordinary shares for all available trading days in the fourth quarter of the end of the performance period to the average closing price per share of the Company’s ordinary shares for all available trading days in the fourth quarter of the year preceding the grant, including dividends, and assessed against a comparable measure of competitor and peer group companies. The details of the executive grants were as follows: Grant Date RSUs Granted Grant Date Fair Value Time-Based Award Vesting Dates Performance-Based Award Vesting Date (in millions) February 2013 1.45 $ 60 Annually on anniversary of grant date, 2014 - 2016 December 31, 2015 February 2014 0.78 53 Annually on anniversary of grant date, 2015 - 2017 December 31, 2016 February 2015 0.90 76 Annually on anniversary of grant date, 2016 - 2018 December 31, 2017 February 2016 0.71 48 Annually on anniversary of grant date, 2017 - 2019 December 31, 2018 February 2017 0.80 63 Annually on anniversary of grant date, 2018 - 2020 December 31, 2019 Any new executives hired after the annual executive RSU grant date may be eligible to participate in the PLC LTIP. Any off cycle grants made for new hires are valued at their grant date fair value based on the closing price of the Company's ordinary shares on the date of such grant. The grant date fair value of the RSUs is determined based on the target number of awards issued, the closing price of the Company’s ordinary shares on the date of the grant of the award, including an estimate for forfeitures, and a contemporaneous valuation performed by an independent valuation specialist with respect to the relative total shareholder return awards. In February 2016, under the time-based vesting terms of the 2013, 2014 and 2015 grants, 395,744 ordinary shares were issued to Delphi executives at a fair value of approximately $24 million , of which 146,726 ordinary shares were withheld to cover minimum withholding taxes. The performance-based RSUs associated with the 2013 grant vested at the completion of a three-year performance period on December 31, 2015, and in the first quarter of 2016, 1,265,339 ordinary shares were issued to Delphi executives at a fair value of approximately $77 million , of which 512,371 ordinary shares were withheld to cover minimum withholding taxes. In February 2017, under the time-based vesting terms of the 2014, 2015 and 2016 grants, 248,008 ordinary shares were issued to Delphi executives at a fair value of approximately $19 million , of which 88,807 ordinary shares were withheld to cover minimum withholding taxes. The performance-based RSUs associated with the 2014 grant vested at the completion of a three-year performance period on December 31, 2016, and in the first quarter of 2017, 797,210 ordinary shares were issued to Delphi executives at a fair value of approximately $60 million , of which 324,555 ordinary shares were withheld to cover minimum withholding taxes. A summary of RSU activity, including award grants, vesting and forfeitures is provided below: RSUs Weighted Average Grant Date Fair Value (in thousands) Nonvested, January 1, 2017 1,740 $ 76.54 Granted 877 79.68 Vested (362 ) 74.42 Forfeited (135 ) 76.76 Nonvested, September 30, 2017 2,120 78.19 Delphi recognized compensation expense of $16 million ( $14 million , net of tax) and $18 million ( $16 million , net of tax) based on the Company’s best estimate of ultimate performance against the respective targets during the three months ended September 30, 2017 and 2016 , respectively. Delphi recognized compensation expense of $48 million ( $42 million , net of tax) and $45 million ( $39 million , net of tax) based on the Company’s best estimate of ultimate performance against the respective targets during the nine months ended September 30, 2017 and 2016 , respectively. Delphi will continue to recognize compensation expense, based on the grant date fair value of the awards applied to the Company’s best estimate of ultimate performance against the respective targets, over the requisite vesting periods of the awards. Based on the grant date fair value of the awards and the Company’s best estimate of ultimate performance against the respective targets as of September 30, 2017 , unrecognized compensation expense on a pre-tax basis of approximately $87 million is anticipated to be recognized over a weighted average period of approximately 2 years. For the nine months ended September 30, 2017 and 2016 , respectively, approximately $33 million and $40 million of cash was paid and reflected as a financing activity in the statements of cash flows related to the minimum statutory tax withholding for vested RSUs.

Supplemental Guarantor And Non-Guarantor Condensed Consolidating Financial Statements [Abstract]
Supplemental Guarantor And Non-Guarantor Condensed Consolidating Financial Statements	SUPPLEMENTAL GUARANTOR AND NON-GUARANTOR CONDENSED CONSOLIDATING FINANCIAL STATEMENTS Basis of Presentation Notes Issued by the Subsidiary Issuer As described in Note 8. Debt, Delphi Corporation (the "Subsidiary Issuer/Guarantor"), a 100% owned subsidiary of Delphi Automotive PLC (the "Parent"), issued the 2013 Senior Notes and the 2014 Senior Notes, both of which were registered under the Securities Act, and is the borrower of obligations under the Credit Agreement. The 2013 Senior Notes were subsequently redeemed and extinguished in September 2016. The 2014 Senior Notes and obligations under the Credit Agreement are, and prior to their redemption, the 2013 Senior Notes were, fully and unconditionally guaranteed by Delphi Automotive PLC and certain of Delphi Automotive PLC's direct and indirect subsidiary companies, which are directly or indirectly 100% owned by Delphi Automotive PLC (the “Subsidiary Guarantors”), on a joint and several basis, subject to customary release provisions (other than in the case of Delphi Automotive PLC). All other consolidated direct and indirect subsidiaries of Delphi Automotive PLC are not subject to the guarantees (“Non-Guarantor Subsidiaries”). Notes Issued by the Parent As described in Note 8. Debt, Delphi Automotive PLC issued the 2015 Senior Notes, the 2015 Euro-denominated Senior Notes, the 2016 Euro-denominated Senior Notes and the 2016 Senior Notes, each of which were registered under the Securities Act. Each series of these senior notes are fully and unconditionally guaranteed on a joint and several basis, subject to customary release provisions, by certain of Delphi Automotive PLC's direct and indirect subsidiary companies (the “Subsidiary Guarantors”), and Delphi Corporation, each of which are directly or indirectly 100% owned by Delphi Automotive PLC. All other consolidated direct and indirect subsidiaries of Delphi Automotive PLC are not subject to the guarantees (“Non-Guarantor Subsidiaries”). Spin-Off Senior Notes As described in Note 8. Debt, in September 2017, Delphi Technologies PLC, a wholly owned subsidiary of the Company, was formed in connection with the planned spin-off of the Powertrain Systems segment. Delphi Technologies PLC is a holding company established to directly, or indirectly, own substantially all of the operating subsidiaries of the spin-off, to issue debt securities and perform treasury operations of the spin-off entity. In September 2017, Delphi Technologies PLC issued $800 million in aggregate principal amount of 5.00% senior unsecured notes due 2025 in a transaction exempt from registration under the Securities Act. The net proceeds from the notes offering were deposited into escrow and are expected to be released in connection with the spin-off. The notes are not guaranteed until their release from escrow, and will not be guaranteed by the Company or any of its subsidiaries that will not be subsidiaries of Delphi Technologies PLC following the spin-off. As Delphi Technologies PLC is not a guarantor of the Company's other indebtedness, it is included in the Non-Guarantor Subsidiaries. In lieu of providing separate audited financial statements for the Guarantors, the Company has included the accompanying condensed consolidating financial statements. These condensed consolidating financial statements are presented on the equity method. Under this method, the investments in subsidiaries are recorded at cost and adjusted for the parent’s share of the subsidiary’s cumulative results of operations, capital contributions and distributions and other equity changes. The Non-Guarantor Subsidiaries are combined in the condensed consolidating financial statements. The principal elimination entries are to eliminate the investments in subsidiaries and intercompany balances and transactions.

Segment Reporting

Segment Reporting	9 Months Ended

Segment Reporting [Abstract]
Segment Reporting	SEGMENT REPORTING Delphi operates its core business along the following operating segments, which are grouped on the basis of similar product, market and operating factors: • Electrical/Electronic Architecture, which includes complete electrical architecture and component products. • Powertrain Systems, which includes extensive systems integration expertise in gasoline, diesel and fuel handling and full end-to-end systems including fuel and air injection, combustion, electronics controls, exhaust handling, test and validation capabilities, electric and hybrid electric vehicle power electronics, aftermarket, and original equipment service. As described in Note 22. Separation of Powertrain Systems, the Company is pursuing a separation of the Powertrain Systems segment into a new, independent publicly traded company, through a transaction expected to be treated as a tax-free spin-off to its shareholders. • Electronics and Safety, which includes component and systems integration expertise in infotainment and connectivity, body controls and security systems, displays and passive and active safety electronics, as well as advanced development of software. • Eliminations and Other, which includes i) the elimination of inter-segment transactions, and ii) certain other expenses and income of a non-operating or strategic nature. The accounting policies of the segments are the same as those described in Note 2. Significant Accounting Policies, except that the disaggregated financial results for the segments have been prepared using a management approach, which is consistent with the basis and manner in which management internally disaggregates financial information for which Delphi’s chief operating decision maker regularly reviews financial results to assess performance of, and make internal operating decisions about allocating resources to, the segments. Generally, Delphi evaluates segment performance based on stand-alone segment net income before interest expense, other income (expense), net, income tax expense, equity income (loss), net of tax, income (loss) from discontinued operations, net of tax, restructuring, separation costs related to the planned spin-off of the Powertrain Systems segment, other acquisition and portfolio project costs (which includes costs incurred to integrate acquired businesses and to plan and execute product portfolio transformation actions, including business and product acquisitions and divestitures), asset impairments and gains (losses) on business divestitures (“Adjusted Operating Income”) and accounts for inter-segment sales and transfers as if the sales or transfers were to third parties, at current market prices. Delphi’s management utilizes Adjusted Operating Income as the key performance measure of segment income or loss to evaluate segment performance, and for planning and forecasting purposes to allocate resources to the segments, as management believes this measure is most reflective of the operational profitability or loss of Delphi's operating segments. Segment Adjusted Operating Income should not be considered a substitute for results prepared in accordance with U.S. GAAP and should not be considered an alternative to net income attributable to Delphi, which is the most directly comparable financial measure to Adjusted Operating Income that is prepared in accordance with U.S. GAAP. Segment Adjusted Operating Income, as determined and measured by Delphi, should also not be compared to similarly titled measures reported by other companies. As described in Note 21. Discontinued Operations, the Company's previously reported Thermal Systems segment has been classified as discontinued operations for all periods presented. No amounts for shared general and administrative operating expense or interest expense were allocated to discontinued operations. Included below are sales and operating data for Delphi’s segments for the three and nine months ended September 30, 2017 and 2016 .

The reconciliation of Adjusted Operating Income to net income attributable to Delphi for the three and nine months ended September 30, 2017 and 2016 are as follows: Electrical/ Powertrain Electronics Eliminations Total (in millions) For the Three Months Ended September 30, 2017: Adjusted operating income $ 336 $ 150 $ 80 $ — $ 566 Restructuring (17 ) (4 ) — — (21 ) Separation costs — (31 ) — — (31 ) Other acquisition and portfolio project costs (1 ) — (1 ) — (2 ) Asset impairments (1 ) — — — (1 ) Operating income $ 317 $ 115 $ 79 $ — 511 Interest expense (36 ) Other expense, net (9 ) Income from continuing operations before income taxes and equity income 466 Income tax expense (60 ) Equity income, net of tax 7 Income from continuing operations 413 Income from discontinued operations, net of tax — Net income 413 Net income attributable to noncontrolling interest 18 Net income attributable to Delphi $ 395 Electrical/ Powertrain Electronics Eliminations Total (in millions) For the Three Months Ended September 30, 2016: Adjusted operating income $ 317 $ 122 $ 95 $ — $ 534 Restructuring (30 ) (22 ) (11 ) — (63 ) Other acquisition and portfolio project costs (4 ) (2 ) (1 ) — (7 ) Asset impairments — — (1 ) — (1 ) Operating income $ 283 $ 98 $ 82 $ — 463 Interest expense (41 ) Other expense, net (69 ) Income from continuing operations before income taxes and equity income 353 Income tax expense (57 ) Equity income, net of tax 10 Income from continuing operations 306 Income from discontinued operations, net of tax — Net income 306 Net income attributable to noncontrolling interest 13 Net income attributable to Delphi $ 293 Electrical/ Powertrain Electronics Eliminations Total (in millions) For the Nine Months Ended September 30, 2017: Adjusted operating income $ 998 $ 472 $ 220 $ — $ 1,690 Restructuring (43 ) (81 ) (56 ) — (180 ) Separation costs — (46 ) — — (46 ) Other acquisition and portfolio project costs (6 ) (2 ) (3 ) — (11 ) Asset impairments (1 ) (8 ) (1 ) — (10 ) Operating income $ 948 $ 335 $ 160 $ — 1,443 Interest expense (105 ) Other expense, net (29 ) Income from continuing operations before income taxes and equity income 1,309 Income tax expense (183 ) Equity income, net of tax 25 Income from continuing operations 1,151 Income from discontinued operations, net of tax — Net income 1,151 Net income attributable to noncontrolling interest 52 Net income attributable to Delphi $ 1,099 Electrical/ Powertrain Electronics Eliminations Total (in millions) For the Nine Months Ended September 30, 2016: Adjusted operating income $ 969 $ 381 $ 276 $ — $ 1,626 Restructuring (65 ) (157 ) (30 ) — (252 ) Other acquisition and portfolio project costs (36 ) (8 ) (6 ) — (50 ) Asset impairments — (22 ) (1 ) — (23 ) Operating income $ 868 $ 194 $ 239 $ — 1,301 Interest expense (123 ) Other expense, net (73 ) Income from continuing operations before income taxes and equity income 1,105 Income tax expense (216 ) Equity income, net of tax 23 Income from continuing operations 912 Income from discontinued operations, net of tax 108 Net income 1,020 Net income attributable to noncontrolling interest 44 Net income attributable to Delphi $ 976

Discontinued Operations

Discontinued Operations	9 Months Ended
	Sep. 30, 2017
Discontinued Operations [Abstract]
Discontinued Operations	DISCONTINUED OPERATIONS During the first quarter of 2015, the Company determined that its previously reported Thermal Systems segment met the criteria to be classified as a discontinued operation as a result of entering into a definitive agreement for the sale of substantially all of the assets and liabilities of the Company's wholly owned Thermal Systems business and a commitment to a plan to dispose of the Company's interests in two joint ventures which were previously reported within the Thermal Systems segment. On June 30, 2015 the Company closed the sale of its wholly owned Thermal Systems business to MAHLE GmbH ("MAHLE"). The Company received cash proceeds of approximately $670 million and recognized a gain on the divestiture within income from discontinued operations of $271 million (approximately $0.95 per diluted share), net of tax expense of $52 million , transaction costs of $10 million and $18 million of pre-tax post-closing adjustments recorded during the year ended December 31, 2015 primarily related to settlement of working capital items and contingent liabilities. Additional post-closing adjustments of $3 million , primarily related to the settlement of contingent liabilities, were recorded as a reduction to the gain on the divestiture during the year ended December 31, 2016. In conjunction with the sale, Delphi and MAHLE also entered into a transition services agreement under which Delphi provided certain administrative and other services, as well as a supply agreement under which Delphi supplied certain products, primarily for a period of up to eighteen months following the closing of the transaction. Delphi recorded $2 million and $7 million to other income (expense), net during the three and nine months ended September 30, 2016 , respectively, for certain fees earned pursuant to the transition services agreement. On September 24, 2015 the Company closed the sale of its 50 percent interest in its Korea Delphi Automotive Systems Corporation ("KDAC") joint venture, which was accounted for under the equity method and was principally reported as part of the Thermal Systems segment, to the joint venture partner. The Company received cash proceeds of $70 million and recognized a gain on the divestiture of $47 million , net of tax expense, within income from discontinued operations during the three months ended September 30, 2015. During the year ended December 31, 2015, the Company recorded a net loss of $41 million (approximately $0.14 per diluted share) on the KDAC divestiture within income from discontinued operations, which includes an impairment loss of $88 million recorded on this investment in the first quarter of 2015 based on the evaluation of the estimated fair value of the Company's interest in KDAC as of March 31, 2015 in relation to its carrying value. On March 31, 2016, the Company closed the sale of its 50 percent interest in its Shanghai Delphi Automotive Air Conditioning ("SDAAC") joint venture to one of the Company's joint venture partners, Shanghai Aerospace Automobile Electromechanical Co., Ltd ("SAAE"). The Company received cash proceeds of $62 million , net of tax, transaction costs and $29 million of cash divested, and recognized a gain on the divestiture of $104 million (approximately $0.38 per diluted share), net of tax expense of $10 million and transaction costs, within income from discontinued operations during the nine months ended September 30, 2016 . The financial results of SDAAC, which were consolidated by Delphi, were historically reported as part of the Thermal Systems segment. As the divestiture of the Thermal Systems segment, including the Company's interests in SDAAC and KDAC and the thermal original equipment service business, represents a strategic shift that will have a major effect on the Company's operations and financial results, the assets and liabilities, operating results, and operating and investing cash flows for the former Thermal Systems segment are presented as discontinued operations separate from the Company’s continuing operations for all periods presented. Discontinued operations also includes the Company's thermal original equipment service business, which was included in the sale of the wholly owned Thermal Systems business, the results of which were previously reported within the Powertrain Systems segment. Certain operations, primarily related to contract manufacturing services, which were previously included within the Thermal Systems reporting segment, were excluded from the scope of the divestiture, and are reported in continuing operations within the Electronics and Safety segment for all periods presented. No amounts for shared general and administrative operating expense or interest expense were allocated to discontinued operations. Delphi has not had significant continuing involvement with the divested Thermal Systems business following the closing of the transactions. A reconciliation of the major classes of line items constituting pre-tax profit or loss of discontinued operations to income from discontinued operations, net of tax as presented in the consolidated statements of operations is as follows: Three Months Ended September 30, Nine Months Ended September 30, 2017 2016 2017 2016 (in millions) Net sales $ — $ — $ — $ 78 Cost of sales — — — 67 Selling, general and administrative — — — 4 Income from discontinued operations before income taxes and equity income — — — 7 Gain on divestiture of discontinued operations, net of tax — — — 104 Adjustment to prior period gain on divestiture, net of tax — — — (3 ) Income from discontinued operations, net of tax — — — 108 Income from discontinued operations attributable to noncontrolling interests — — — 3 Net income from discontinued operations attributable to Delphi $ — $ — $ — $ 105 Income from discontinued operations before income taxes attributable to Delphi was $0 and $115 million for the nine months ended September 30, 2017 and 2016 , respectively. No assets or liabilities were classified as held for sale as of September 30, 2017 or December 31, 2016.

Separation of Powertrain System

Separation of Powertrain Systems	9 Months Ended
	Sep. 30, 2017
Disposal Group, Not Discontinued Operation, Disposal Disclosures [Abstract]
Separation of Powertrain Systems	22. SEPARATION OF POWERTRAIN SYSTEMS On May 3, 2017 , the Company announced its intention to pursue a separation of its Powertrain Systems segment into a new, independent publicly traded company, through a transaction expected to be treated as a tax-free spin-off to its shareholders (the "Separation"). The Company plans to complete the Separation by March 2018 , subject to customary closing conditions. The new publicly traded Powertrain spin-off company will be named Delphi Technologies PLC, and will trade on the New York Stock Exchange ("NYSE") under the symbol "DLPH" following the distribution date. As described in Note 8. Debt, in September 2017 Delphi Technologies PLC, the holding company formed in connection with the Separation, completed the offering of $800 million aggregate principal amount of 5.00% senior unsecured notes due 2025 , and entered into the Spin-Off Credit Agreement, which will provide a secured five-year $750 million term loan facility and a $500 million five-year senior secured revolving credit facility in connection with the Separation. During the three and nine months ended September 30, 2017 , the Company incurred costs of $31 million and $46 million , respectively, related to the Separation. These costs, which are included in selling, general and administrative expense within the consolidated statement of operations, were primarily related to third party professional fees associated with planning the Separation.

Significant Accounting Polici30

Significant Accounting Policies (Policies)	9 Months Ended
	Sep. 30, 2017
Accounting Policies [Abstract]
Consolidation, Policy	Consolidation —The consolidated financial statements include the accounts of Delphi and U.S. and non-U.S. subsidiaries in which Delphi holds a controlling financial or management interest and variable interest entities of which Delphi has determined that it is the primary beneficiary. Delphi’s share of the earnings or losses of non-controlled affiliates over which Delphi exercises significant influence (generally a 20% to 50% ownership interest) is included in the consolidated operating results using the equity method of accounting. When Delphi does not have the ability to exercise significant influence (generally when ownership interest is less than 20%), investments in non-consolidated affiliates are accounted for using the cost method. All significant intercompany transactions and balances between consolidated Delphi businesses have been eliminated. The Company monitors its investments in affiliates for indicators of other-than-temporary declines in value on an ongoing basis. If the Company determines that such a decline has occurred, an impairment loss is recorded, which is measured as the difference between carrying value and estimated fair value. Estimated fair value is generally determined using an income approach based on discounted cash flows or negotiated transaction values. During the three and nine months ended September 30, 2017 , Delphi received a dividend of $7 million from one of its equity method investments. During the three and nine months ended September 30, 2016 , Delphi received dividends of $4 million and $8 million , respectively, from one of its equity method investments. The dividends were recognized as a reduction to the investment and represented a return on investment included in cash flows from operating activities. Investments in affiliates accounted for under the cost method totaled $77 million and $26 million as of September 30, 2017 and December 31, 2016 , respectively, and are classified within other long-term assets in the consolidated balance sheet.
Use of Estimates, Policy	Use of estimates —Preparation of consolidated financial statements in conformity with U.S. GAAP requires the use of estimates and assumptions that affect amounts reported therein. Generally, matters subject to estimation and judgment include amounts related to accounts receivable realization, inventory obsolescence, asset impairments, useful lives of intangible and fixed assets, deferred tax asset valuation allowances, income taxes, pension benefit plan assumptions, accruals related to litigation, warranty costs, environmental remediation costs, contingent consideration arrangements, worker’s compensation accruals and healthcare accruals. Due to the inherent uncertainty involved in making estimates, actual results reported in future periods may be based upon amounts that differ from those estimates.
Net Income Per Share, Policy	Net income per share —Basic net income per share is computed by dividing net income attributable to Delphi by the weighted average number of ordinary shares outstanding during the period. Diluted net income per share reflects the weighted average dilutive impact of all potentially dilutive securities from the date of issuance and is computed using the treasury stock method by dividing net income attributable to Delphi by the diluted weighted average number of ordinary shares outstanding. See Note 12. Shareholders’ Equity and Net Income Per Share for additional information including the calculation of basic and diluted net income per share. Basic net income per share is computed by dividing net income attributable to Delphi by the weighted average number of ordinary shares outstanding during the period. Diluted net income per share reflects the weighted average dilutive impact of all potentially dilutive securities from the date of issuance and is computed using the treasury stock method by dividing net income attributable to Delphi by the diluted weighted average number of ordinary shares outstanding. For all periods presented, the calculation of diluted net income per share contemplates the dilutive impacts, if any, of the Company’s share-based compensation plans. Refer to Note 18. Share-Based Compensation for additional information.
Cash and Cash Equivalents, Policy	Cash and cash equivalents —Cash and cash equivalents are defined as short-term, highly liquid investments with original maturities of three months or less.
Cash in escrow related to Powertrain Spin-off debt, Policy	Cash in escrow related to Powertrain Spin-off debt —As of September 30, 2017 , the Company deposited into escrow $796 million of net proceeds from the issuance of $800 million principal amount of unsecured senior notes by Delphi Technologies PLC, a wholly owned subsidiary of the Company formed in connection with the planned spin-off of the Company's Powertrain Systems segment, which prior to October 10, 2017 was named Delphi Jersey Holdings plc. These proceeds will be released to Delphi Technologies PLC upon satisfaction of certain conditions, including completion of the Separation. At December 31, 2016 , there was no cash in escrow for this purpose. Refer to Note 8. Debt for further description of this senior notes offering.
Transfers and Servicing of Financial Assets, Policy	Accounts receivable —Delphi enters into agreements to sell certain of its accounts receivable, primarily in North America and Europe. Sales of receivables are accounted for in accordance with FASB Topic ASC 860, Transfers and Servicing ("ASC 860"). Agreements which result in true sales of the transferred receivables, as defined in ASC 860, which occur when receivables are transferred without recourse to the Company, are excluded from amounts reported in the consolidated balance sheets. Cash proceeds received from such sales are included in operating cash flows. Agreements that allow Delphi to maintain effective control over the transferred receivables and which do not qualify as a sale, as defined in ASC 860, are accounted for as secured borrowings and recorded in the consolidated balance sheets within accounts receivable, net and short-term debt. The expenses associated with receivables factoring are recorded in the consolidated statements of operations within interest expense.
Intangible Assets, Policy	Intangible assets —Intangible assets were $1,213 million and $1,240 million as of September 30, 2017 and December 31, 2016 , respectively. Delphi amortizes definite-lived intangible assets over their estimated useful lives. Delphi has definite-lived intangible assets related to patents and developed technology, customer relationships and trade names. Indefinite-lived in-process research and development intangible assets are not amortized, but are tested for impairment annually, or more frequently when indicators of potential impairment exist, until the completion or abandonment of the associated research and development efforts. The Company also has intangible assets related to acquired trade names that are classified as indefinite-lived when there are no foreseeable limits on the periods of time over which they are expected to contribute cash flows. These indefinite-lived trade name assets are tested for impairment annually, or more frequently when indicators of potential impairment exist. Costs to renew or extend the term of acquired intangible assets are recognized as expense as incurred. Amortization expense was $34 million and $100 million for the three and nine months ended September 30, 2017 and $34 million and $101 million for the three and nine months ended September 30, 2016 , respectively.
Goodwill, Policy	Goodwill —Goodwill is the excess of the purchase price over the estimated fair value of identifiable net assets acquired in business combinations. The Company tests goodwill for impairment annually in the fourth quarter, or more frequently when indications of potential impairment exist. The Company monitors the existence of potential impairment indicators throughout the fiscal year. The Company tests for goodwill impairment at the reporting unit level. Our reporting units are the components of operating segments which constitute businesses for which discrete financial information is available and is regularly reviewed by segment management. The impairment test involves first qualitatively assessing goodwill for impairment. If the qualitative assessment is not met the Company then performs a quantitative assessment by first comparing the estimated fair value of each reporting unit to its carrying value, including goodwill. Fair value reflects the price a market participant would be willing to pay in a potential sale of the reporting unit. If the estimated fair value exceeds carrying value, then we conclude that no goodwill impairment has occurred. If the carrying value of the reporting unit exceeds its estimated fair value, a second step is required to measure possible goodwill impairment loss. The second step includes hypothetically valuing the tangible and intangible assets and liabilities of the reporting unit as if the reporting unit had been acquired in a business combination. Then, the implied fair value of the reporting unit's goodwill is compared to the carrying value of that goodwill. If the carrying value of the reporting unit's goodwill exceeds the implied fair value of the goodwill, the Company recognizes an impairment loss in an amount equal to the excess, not to exceed the carrying value. There were no indicators of potential goodwill impairment during the nine months ended September 30, 2017 . Goodwill was $1,670 million and $1,508 million as of September 30, 2017 and December 31, 2016 , respectively.
Warranty, Policy	Warranty and product recalls —Expected warranty costs for products sold are recognized at the time of sale of the product based on an estimate of the amount that eventually will be required to settle such obligations. These accruals are based on factors such as past experience, production changes, industry developments and various other considerations. Costs of product recalls, which may include the cost of the product being replaced as well as the customer’s cost of the recall, including labor to remove and replace the recalled part, are accrued as part of our warranty accrual at the time an obligation becomes probable and can be reasonably estimated. These estimates are adjusted from time to time based on facts and circumstances that impact the status of existing claims. Refer to Note 6. Warranty Obligations for additional information. Expected warranty costs for products sold are recognized principally at the time of sale of the product based on an estimate of the amount that eventually will be required to settle such obligations. These accruals are based on factors such as past experience, production changes, industry developments and various other considerations. The estimated costs related to product recalls based on a formal campaign soliciting return of that product are accrued at the time an obligation becomes probable and can be reasonably estimated. These estimates are adjusted from time to time based on facts and circumstances that impact the status of existing claims. Delphi has recognized its best estimate for its total aggregate warranty reserves, including product recall costs, across all of its operating segments as of September 30, 2017 . The Company estimates the reasonably possible amount to ultimately resolve all matters in excess of the recorded reserves as of September 30, 2017 to be zero to $30 million .
Discontinued Operations, Policy	Discontinued operations —The Company reports financial results for discontinued operations separately from continuing operations to distinguish the financial impact of disposal transactions from ongoing operations. Discontinued operations reporting occurs only when the disposal of a component or a group of components of the Company represents a strategic shift that will have a major effect on the Company's operations and financial results. During the year ended December 31, 2015, Delphi completed the divestitures of the Company's wholly owned Thermal Systems business and the Company's interest in its KDAC joint venture. During the nine months ended September 30, 2016 , Delphi completed the divestiture of its interest in its Shanghai Delphi Automotive Air Conditioning ("SDAAC") joint venture. Delphi's interests in the KDAC and SDAAC joint ventures were previously reported within the Thermal Systems segment. Accordingly, the assets and liabilities, operating results and operating and investing cash flows for the previously reported Thermal Systems segment are presented as discontinued operations separate from the Company’s continuing operations and segment results for all periods presented in these consolidated financial statements and the notes to the consolidated financial statements, unless otherwise noted. Refer to Note 21. Discontinued Operations for further information regarding the Company's discontinued operations.
Income Tax, Policy	Income taxes —Deferred tax assets and liabilities reflect temporary differences between the amount of assets and liabilities for financial and tax reporting purposes. Such amounts are adjusted, as appropriate, to reflect changes in tax rates expected to be in effect when the temporary differences reverse. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in earnings in the period that includes the enactment date. A valuation allowance is recorded to reduce deferred tax assets to the amount that is more likely than not to be realized. In the event the Company determines it is more likely than not that the deferred tax assets will not be realized in the future, the valuation allowance adjustment to the deferred tax assets will be charged to earnings in the period in which the Company makes such a determination. In determining the provision for income taxes for financial statement purposes, the Company makes certain estimates and judgments which affect its evaluation of the carrying value of its deferred tax assets, as well as its calculation of certain tax liabilities. Refer to Note 11. Income Taxes for additional information.
Restructuring, Policy	Restructuring —Delphi continually evaluates alternatives to align the business with the changing needs of its customers and to lower operating costs. This includes the realignment of its existing manufacturing capacity, facility closures, or similar actions, either in the normal course of business or pursuant to significant restructuring programs. These actions may result in employees receiving voluntary or involuntary employee termination benefits, which are mainly pursuant to union or other contractual agreements. Voluntary termination benefits are accrued when an employee accepts the related offer. Involuntary termination benefits are accrued upon the commitment to a termination plan and when the benefit arrangement is communicated to affected employees, or when liabilities are determined to be probable and estimable, depending on the existence of a substantive plan for severance or termination. Contract termination costs are recorded when contracts are terminated or when Delphi ceases to use the leased facility and no longer derives economic benefit from the contract. All other exit costs are expensed as incurred. Refer to Note 7. Restructuring for additional information.
Customer Concentations, Policy	Customer concentrations —As reflected in the table below, combined net sales from continuing operations to General Motors Company ("GM") and Volkswagen Group ("VW"), Delphi's two largest customers, totaled approximately 19% and 21% of our total net sales for the three and nine months ended September 30, 2017 , respectively, and 23% and 22% for the three and nine months ended September 30, 2016 respectively. Percentage of Total Net Sales Accounts and Other Receivables Three Months Ended September 30, Nine Months Ended September 30, September 30, December 31, 2017 2016 2017 2016 (in millions) GM 11 % 15 % 13 % 14 % $ 291 $ 370 VW 8 % 8 % 8 % 8 % 205 150
Retrospective changes, Policy	Retrospective changes —Prior period information has been reclassified as a result of the Company's adoption of Accounting Standards Update ("ASU") 2017-07, as defined and further described below, on a retrospective basis in 2017. In accordance with the adoption of this guidance, prior year amounts related to the components of net periodic pension and postretirement benefit cost other than service costs have been reclassified from cost of goods sold and selling, general and administrative expense to other expense within the consolidated statement of operations for all periods presented.
Recently Issued Accounting Pronouncements, Policy	Recently adopted accounting pronouncements —Delphi adopted ASU 2015-11, Inventory (Topic 330): Simplifying the Measurement of Inventory , in the first quarter of 2017 on a prospective basis. This guidance requires an entity to measure inventory at the lower of cost and net realizable value, rather than at the lower of cost or market. The adoption of this guidance did not have a significant impact on Delphi's financial statements. Delphi adopted ASU 2016-05, Derivatives and Hedging (Topic 815): Effect of Derivative Contract Novations on Existing Hedge Accounting Relationships and ASU 2016-06, Derivatives and Hedging (Topic 815): Contingent Put and Call Options in Debt Instruments in the first quarter of 2017 on a prospective basis. ASU 2016-05 clarifies that a change in the counterparty to a derivative instrument that has been designated as a hedging instrument does not, in and of itself, require dedesignation of that hedging relationship provided that all other hedge accounting criteria continue to be met. ASU 2016-06 also clarifies the steps required to determine bifurcation of an embedded derivative. The adoption of this guidance did not have a significant impact on Delphi's financial statements. Delphi adopted ASU 2016-09, Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting ("ASU 2016-09") in the first quarter of 2017. This guidance contains multiple updates related to the accounting and financial statement presentation of share-based payment transactions. The provisions of ASU 2016-09 related to the timing of when excess tax benefits are recognized were adopted using a modified retrospective transition method by means of an immaterial cumulative-effect adjustment to equity as of January 1, 2017. On a prospective basis, excess tax benefits are recognized within income tax expense in the period in which the awards vest, as opposed to being recognized in additional paid-in capital when the deduction reduced taxes payable. Such excess tax benefits are classified as an operating activity within the consolidated statement of cash flows prospectively, as opposed to a financing activity. There was no change to the Company's historical presentation of minimum statutory withholdings as a financing activity within the consolidated statement of cash flows. The Company’s share-based compensation expense continues to reflect estimated forfeitures. The adoption of ASU 2016-09 did not materially impact the Company’s financial position, results of operations, equity or cash flows. Delphi adopted ASU 2017-07, Compensation—Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost ("ASU 2017-07") in the first quarter of 2017. ASU 2017-07 changes the presentation of net periodic pension and postretirement benefit cost in the income statement. Under the new guidance, employers present the service cost component of the net periodic benefit cost in the same income statement line items as other employee compensation costs for services rendered during the period. In addition, only the service cost component is eligible for capitalization as an asset. Employers present the other components of net periodic benefit cost separately from the income statement line items that include the service cost component, outside of operating income. The new guidance is effective for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. Early adoption is permitted as of the beginning of an annual period. The new guidance related to the presentation of the components of net periodic benefit cost within the income statement is to be applied retrospectively. The new guidance limiting the capitalization of net periodic benefit cost in assets to the service cost component will be applied prospectively. As permitted, the Company elected to early adopt this guidance effective January 1, 2017, and has classified the components of net periodic pension and postretirement benefit cost other than service costs from cost of goods sold and selling, general and administrative expense to other expense within the consolidated statement of operations for all periods presented. The adoption of this guidance resulted in the reclassification of $3 million and $9 million of net periodic benefit cost components other than service cost from operating expense to other expense for the three and nine months ended September 30, 2016 , respectively, and had no impact on net income attributable to Delphi. Approximately $9 million and $25 million of net periodic benefit cost components other than service cost are included within other expense for the three and nine months ended September 30, 2017 , respectively. Refer to Note. 9. Pension Benefits for further detail of the components of net periodic benefit costs. Recently issued accounting pronouncements not yet adopted —In May 2014, the Financial Accounting Standards Board ("FASB") issued ASU 2014-09, Revenue from Contracts with Customers . This ASU supersedes most of the existing guidance on revenue recognition in Accounting Standards Codification ("ASC") Topic 605, Revenue Recognition and establishes a broad principle that would require an entity to recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. To achieve this principle, an entity identifies the contract with a customer, identifies the separate performance obligations in the contract, determines the transaction price, allocates the transaction price to the separate performance obligations and recognizes revenue when each separate performance obligation is satisfied. The FASB has subsequently issued additional ASUs to clarify certain elements of the new revenue recognition guidance. The guidance is effective for fiscal years beginning after December 15, 2017 and is to be applied retrospectively using one of two transition methods at the entity's election. The full retrospective method requires companies to recast each prior reporting period presented as if the new guidance had always existed. Under the modified retrospective method, companies would recognize the cumulative effect of initially applying the standard as an adjustment to opening retained earnings at the date of initial application. The Company has continued to monitor FASB activity related to the new standard, and has worked with various non-authoritative industry groups to assess certain interpretative issues and the associated implementation of the new standard. The Company has drafted its accounting policy for the new standard based on a detailed review of its business and contracts. While the Company continues to assess all potential impacts of the new standard, we do not currently expect that the adoption of the new revenue standard will have a material impact on our revenues, results of operations or financial position. As a result of the adoption of this standard, the Company expects to make additional disclosures related to the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers as required by the new standard. The Company plans to adopt the new revenue standard effective January 1, 2018. The Company currently intends to adopt the new standard using the modified retrospective method, and continues to evaluate the effect of the standard on our ongoing financial reporting. In January 2016, the FASB issued ASU 2016-01, Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities. This guidance makes targeted improvements to existing U.S. GAAP for financial instruments, including requiring equity investments (except those accounted for under the equity method of accounting, or those that result in consolidation of the investee) to be measured at fair value with changes in fair value recognized in net income as opposed to other comprehensive income; requiring entities to use the exit price notion when measuring the fair value of financial instruments for disclosure purposes; requiring separate presentation of financial assets and financial liabilities by measurement category and form of financial asset; and requiring entities to present separately in other comprehensive income the portion of the total change in the fair value of a liability resulting from a change in the instrument-specific credit risk (also referred to as “own credit”) when the organization has elected to measure the liability at fair value in accordance with the fair value option. The new guidance is effective for public companies for fiscal years beginning after December 15, 2017 by means of a cumulative-effect adjustment to the balance sheet as of the beginning of the fiscal year of adoption. Early adoption of the own credit provision is permitted. The Company is currently evaluating the impact that the adoption of this guidance will have on its consolidated financial statements; however, based on the nature of financial instruments held by Delphi as of September 30, 2017 , the Company does not currently expect that the adoption of ASU 2016-01 will have a material impact on its financial position, results of operations or cash flows. The Company will continue to evaluate any changes in its investments or market conditions, and the related potential impacts of the adoption of ASU 2016-01. In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842) . Under this guidance, lessees will be required to recognize on the balance sheet a lease liability and a right-of-use asset for all leases, with the exception of short-term leases. The lease liability represents the lessee's obligation to make lease payments arising from a lease, and will be measured as the present value of the lease payments. The right-of-use asset represents the lessee’s right to use a specified asset for the lease term, and will be measured at the lease liability amount, adjusted for lease prepayment, lease incentives received and the lessee’s initial direct costs. The standard also requires a lessee to recognize a single lease cost allocated over the lease term, generally on a straight-line basis. The new guidance is effective for fiscal years beginning after December 15, 2018. ASU 2016-02 is required to be applied using the modified retrospective approach for all leases existing as of the effective date and provides for certain practical expedients. Early adoption is permitted. The Company is currently evaluating the effects that the adoption of ASU 2016-02 will have on the Company’s consolidated financial statements, and anticipates the new guidance will significantly impact its consolidated financial statements as the Company has a significant number of leases. In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments . This guidance requires the measurement of all expected credit losses for financial assets held at the reporting date based on historical experience, current conditions and reasonable and supportable forecasts. This guidance also requires enhanced disclosures regarding significant estimates and judgments used in estimating credit losses. The new guidance is effective for fiscal years beginning after December 15, 2019. Early adoption is permitted for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018. The Company is currently evaluating the impact that the adoption of this guidance will have on its consolidated financial statements. In September 2016, the FASB issued ASU 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments . This guidance clarifies the presentation requirements of eight specific issues within the statement of cash flows. The new guidance is effective for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. Early adoption is permitted. The adoption of this guidance is not expected to have a significant impact on Delphi's financial statements, as Delphi's treatment of the relevant affected items within its consolidated statement of cash flows is consistent with the requirements of this guidance. In October 2016, the FASB issued ASU No. 2016-16, Accounting for Income Taxes: Intra-Entity Asset Transfers of Assets Other than Inventory . This guidance requires that the tax effects of all intra-entity sales of assets other than inventory be recognized in the period in which the transaction occurs. The new guidance is effective for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. Early adoption as of the beginning of an annual reporting period is permitted. The guidance is to be applied on a modified retrospective basis through a cumulative-effect adjustment to retained earnings as of the beginning of the period of adoption. The Company is currently evaluating the impact that the adoption of this guidance will have on its consolidated financial statements. In November 2016, the FASB issued ASU 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash . This guidance requires that a statement of cash flows explain the change during the period in the total of cash, cash equivalents, and restricted cash. As a result, restricted cash will be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. The new guidance is effective for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. Early adoption is permitted, and the new guidance is to be applied retrospectively. The adoption of this guidance is not expected to have a significant impact on Delphi's financial statements, other than the classification of restricted cash within the beginning-of-period and end-of-period totals on the consolidated statement of cash flows, as opposed to being excluded from these totals. In January 2017, the FASB issued ASU 2017-04, Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment . This guidance simplifies how an entity is required to test goodwill for impairment by eliminating step two from the goodwill impairment test, which measures a goodwill impairment loss by comparing the implied fair value of a reporting unit’s goodwill with the carrying amount. Under the new guidance, if a reporting unit’s carrying amount exceeds its fair value, an entity will record an impairment charge based on that difference. The impairment charge will be limited to the amount of goodwill allocated to that reporting unit. The standard will be applied prospectively and is effective for annual and interim impairment tests performed in periods beginning after December 15, 2019. Early adoption is permitted. The Company is currently evaluating the impact of adopting this standard on its financial statements, but does not anticipate a material impact. As this standard is prospective in nature, the impact to Delphi's financial statements of not performing a step two in order to measure the amount of any potential goodwill impairment will depend on various factors associated with the Company's assessment of goodwill for impairment in those future periods. In August 2017, the FASB issued ASU 2017-12, Derivatives and Hedging - Targeted Improvements to Accounting for Hedging Activities , which expands and refines the application of hedge accounting for both non-financial and financial risk components and aligns the recognition and presentation of the effects of the hedging instrument and the hedged item in the financial statements. The standard is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early adoption is permitted. The Company is currently evaluating the impact that the adoption of this guidance will have on its consolidated financial statements.
Inventories, Policy	Inventories are stated at the lower of cost, determined on a first-in, first-out basis, or net realizable value, including direct material costs and direct and indirect manufacturing costs.
Pensions, Policy	Certain of Delphi’s non-U.S. subsidiaries sponsor defined benefit pension plans, which generally provide benefits based on negotiated amounts for each year of service. Delphi’s primary non-U.S. plans are located in France, Germany, Mexico, Portugal and the United Kingdom (“U.K.”). The U.K. and certain Mexican plans are funded. In addition, Delphi has defined benefit plans in South Korea, Turkey and Italy for which amounts are payable to employees immediately upon separation. The obligations for these plans are recorded over the requisite service period. Delphi sponsors a Supplemental Executive Retirement Program (“SERP”) for those employees who were U.S. executives of the former Delphi Corporation (now known as DPH Holdings Corp. (“DPHH”)) prior to September 30, 2008 and were still U.S. executives of Delphi on October 7, 2009, the effective date of the program. This program is unfunded. Executives receive benefits over 5 years after an involuntary or voluntary separation from Delphi. The SERP is closed to new members.
Guarantor, Policy	In lieu of providing separate audited financial statements for the Guarantors, the Company has included the accompanying condensed consolidating financial statements. These condensed consolidating financial statements are presented on the equity method. Under this method, the investments in subsidiaries are recorded at cost and adjusted for the parent’s share of the subsidiary’s cumulative results of operations, capital contributions and distributions and other equity changes. The Non-Guarantor Subsidiaries are combined in the condensed consolidating financial statements. The principal elimination entries are to eliminate the investments in subsidiaries and intercompany balances and transactions.
Segment Reporting, Policy	The accounting policies of the segments are the same as those described in Note 2. Significant Accounting Policies, except that the disaggregated financial results for the segments have been prepared using a management approach, which is consistent with the basis and manner in which management internally disaggregates financial information for which Delphi’s chief operating decision maker regularly reviews financial results to assess performance of, and make internal operating decisions about allocating resources to, the segments. Generally, Delphi evaluates segment performance based on stand-alone segment net income before interest expense, other income (expense), net, income tax expense, equity income (loss), net of tax, income (loss) from discontinued operations, net of tax, restructuring, separation costs related to the planned spin-off of the Powertrain Systems segment, other acquisition and portfolio project costs (which includes costs incurred to integrate acquired businesses and to plan and execute product portfolio transformation actions, including business and product acquisitions and divestitures), asset impairments and gains (losses) on business divestitures (“Adjusted Operating Income”) and accounts for inter-segment sales and transfers as if the sales or transfers were to third parties, at current market prices. Delphi’s management utilizes Adjusted Operating Income as the key performance measure of segment income or loss to evaluate segment performance, and for planning and forecasting purposes to allocate resources to the segments, as management believes this measure is most reflective of the operational profitability or loss of Delphi's operating segments. Segment Adjusted Operating Income should not be considered a substitute for results prepared in accordance with U.S. GAAP and should not be considered an alternative to net income attributable to Delphi, which is the most directly comparable financial measure to Adjusted Operating Income that is prepared in accordance with U.S. GAAP. Segment Adjusted Operating Income, as determined and measured by Delphi, should also not be compared to similarly titled measures reported by other companies.
