Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization, Consolidation and Presentation of Financial Statements Disclosure [Text Block]	Note 1. BASIS OF PRESENTATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES On October 31, 2016, Adient plc ("Adient" or the "Company") became an independent company as a result of the separation of the automotive seating and interiors businesses of Johnson Controls International plc ("JCI", "Johnson Controls" or "Parent"). Adient was incorporated under the laws of Ireland on June 24, 2016 for the purpose of holding these businesses. Adient's ordinary shares began trading "regular-way" under the ticker symbol "ADNT" on the New York Stock Exchange on October 31, 2016. Upon becoming an independent company, the capital structure of Adient consisted of 500 million authorized ordinary shares and 100 million authorized preferred shares (par value of $ 0.001 per ordinary and preferred share). The number of Adient ordinary shares issued on October 31, 2016 was 93,671,810. Adient is the world's largest automotive seating supplier. Adient has a leading market position in the Americas, Europe and China, and has longstanding relationships with the largest global original equipment manufacturers, or OEMs, in the automotive space. Adient's proprietary technologies extend into virtually every area of automotive seating solutions, including complete seating systems, frames, mechanisms, foam, head restraints, armrests, trim covers and fabrics. Adient is an independent seat supplier with global scale and the capability to design, develop, engineer, manufacture, and deliver complete seat systems and components in every major automotive producing region in the world. Adient also participates in the automotive interiors market primarily through its global automotive interiors joint venture in China, Yanfeng Global Automotive Interior Systems Co., Ltd., or YFAI. The separation was completed pursuant to various agreements with JCI related to the separation. These agreements govern the relationship between Adient and JCI following the separation and provided for the allocation of various assets, liabilities, rights and obligations. These agreements also include arrangements for transition services to be provided on a temporary basis by both parties. Basis of Presentation The financial statements for periods prior to October 31, 2016 were prepared on a stand-alone combined basis derived from the consolidated financial statements and accounting records of JCI as if Adient had been operating as a stand-alone company for all periods presented. These financial statements have been prepared in accordance with generally accepted accounting principles in the United States of America ("U.S. GAAP"). The assets and liabilities in the financial statements have been reflected on a historical cost basis, as included in the consolidated statements of financial position of JCI. The statements of income include allocations for certain support functions that were provided on a centralized basis by the former Parent and subsequently recorded at the business unit level, such as expenses related to employee benefits, finance, human resources, risk management, information technology, facilities, and legal, among others. These expenses have been allocated to the Company on the basis of direct usage when identifiable, with the remainder allocated on a proportional basis of combined sales, headcount or other measures of the Company or the Parent. Management believes the assumptions underlying the financial statements, including the assumptions regarding allocating general corporate expenses from JCI, are reasonable. Nevertheless, the financial statements for periods prior to the separation may not include all actual expenses that would have been incurred by Adient and may not reflect the results of operations, financial position and cash flows had it been a stand-alone company during the periods presented. Actual costs that would have been incurred if Adient had been a stand-alone company would depend on multiple factors, including organizational structure and strategic decisions made in various areas, including information technology and infrastructure. The financial statements for periods prior to the separation include certain assets and liabilities that have historically been held at JCI but are specifically identifiable or otherwise attributable to Adient. All significant intercompany transactions and accounts within the Company's businesses have been eliminated. All intercompany transactions between the Company and JCI prior to the separation have been included in the consolidated financial statements as Parent's net investment. Expenses related to corporate allocations from JCI to the Company are considered to be effectively settled for cash in the financial statements at the time the transaction is recorded. In addition, transactions between the Company and JCI's other businesses prior to the separation have been classified as related party, rather than intercompany, in the financial statements. See Note 15, "Related Party Transactions and Parent's Net Investment," of the notes to consolidated financial statements for further details. Prior to the separation, transfers of cash to and from JCI's cash management system were reflected as a component of Parent's net investment in the consolidated statements of financial position. For periods prior to the separation, the cash and cash equivalents held by JCI were not attributed to the Company, as legal ownership remained with the former Parent. Furthermore, the income tax expense and deferred taxes in the financial statements for periods prior to October 31, 2016 were prepared on a separate return basis derived from the consolidated financial statements and accounting records of JCI as if Adient had been operating as a stand-alone company for all periods presented. As a standalone entity, Adient will file tax returns on its own behalf and its effective tax rate and deferred taxes may differ from those in historical periods. The accompanying consolidated financial statements presented herein are unaudited and should be read in conjunction with the combined financial statements presented in the Company's 2016 Annual Report on Form 10-K. These consolidated financial statements have been prepared in accordance with U.S. GAAP. Such financial statements reflect all adjustments that, in the opinion of management, are necessary for a fair statement of the results of the interim periods presented; all such adjustments are of a normal recurring nature except for the impacts of adopting new accounting standards as discussed below. All significant intercompany accounts and transactions have been eliminated. The results of operations for the three months ended December 31, 2016 are not necessarily indicative of the results of operations for the year ending September 30, 2017. In addition to wholly-owned subsidiaries, the Company has investments which, in certain cases, may or may not require combination, as a result of only a partial-ownership interest and/or lack of significant influence over the investee. The Company's investments in partially-owned affiliates are accounted for by the equity method when the Company's interest exceeds 20% and the Company does not have a controlling interest. Consolidated VIEs Based upon the criteria set forth in Financial Accounting Standards Board (FASB) Accounting Standards Codification (ASC) 810, "Consolidation," the Company has determined that it was the primary beneficiary in two variable interest entities (VIEs) for the reporting periods ended December 31, 2016 and September 30, 2016 , as the Company absorbs significant economics of the entities and has the power to direct the activities that are considered most significant to the entities. The two VIEs manufacture seating products in North America for the automotive industry. The Company funds the entities' short-term liquidity needs through revolving credit facilities and has the power to direct the activities that are considered most significant to the entities through its key customer supply relationships. The carrying amounts and classification of assets (none of which are restricted) and liabilities included in the Company's consolidated statements of financial position for the consolidated VIEs are as follows: (in millions) December 31, September 30, Current assets $ 257 $ 281 Noncurrent assets 44 45 Total assets $ 301 $ 326 Current liabilities $ 192 $ 219 Total liabilities $ 192 $ 219 Restricted Cash At September 30, 2016, the Company recorded $2 billion of restricted cash within the consolidated statements of financial position. These funds represent the proceeds from the bond issuance which were placed directly into escrow and released to the Company subsequent to September 30, 2016 and therefore represents non-cash activity in fiscal 2016. The cash was used during the three months ended December 31, 2016 in part, to fund a distribution to Johnson Controls. The $2 billion receipt of cash from escrow, along with the distribution to and other settlements with the former Parent during the three months ended December 31, 2016 are reflected in net transfers from parent in the consolidated statement of cash flows. Refer to Note 5, "Debt and Financing Arrangements," of the notes to the consolidated financial statements for further information on the bond issuance. Earnings Per Share The following table shows the computation of basic and diluted earnings per share: Three Months Ended (in millions, except per share data) 2016 2015 Numerator: Net income attributable to Adient $ 149 $ 137 Denominator: Shares outstanding 93.7 93.7 Effect of dilutive securities 0.2 0.1 Diluted shares 93.9 93.8 Earnings per share: Basic $ 1.59 $ 1.46 Diluted $ 1.59 $ 1.46 For periods prior to the separation, the computation of basic and diluted earnings per ordinary share is calculated assuming the number of Adient ordinary shares outstanding on October 31, 2016 had been outstanding at the beginning of each period presented. Potentially dilutive securities whose effect would have been antidilutive are excluded from the computation of diluted earnings per share. New Accounting Pronouncements Recently Adopted Accounting Pronouncements In February 2015, the FASB issued ASU No. 2015-02, "Consolidation (Topic 810): Amendments to the Consolidation Analysis." ASU No. 2015-02 amends the analysis performed to determine whether a reporting entity should consolidate certain types of legal entities. ASU No. 2015-02 was effective retrospectively for the Company for the quarter ending December 31, 2016. The adoption of this guidance did not have an impact on the Company's consolidated financial statements. In April 2015, the FASB issued ASU No. 2015-03, "Interest-Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs." ASU No. 2015-03 requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of the debt liability. ASU No. 2015-03 was applied retrospectively by the Company during the quarter ended December 31, 2016. As a result, other noncurrent assets and long-term debt decreased by $43 million at September 30, 2016 in the Company's consolidated statements of financial position. In May 2015, the FASB issued ASU No. 2015-07, "Disclosures for Investments in Certain Entities That Calculate Net Asset Value per Share (or Its Equivalent)." ASU No. 2015-07 removes the requirement to categorize within the fair value hierarchy all investments for which fair value is measured using the net asset value per share practical expedient. Such investments should be disclosed separate from the fair value hierarchy. ASU No. 2015-07 was effective retrospectively for the Company for the quarter ended December 31, 2016. The adoption of this guidance did not have an impact on the Company's consolidated financial statements for the quarter ended December 31, 2016 but will impact pension asset disclosures for annual reporting. In March 2016, the FASB issued ASU No. 2016-09, "Compensation-Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting." ASU No. 2016-09 changes the accounting for certain aspects of share-based payments to employees, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. In addition, the guidance allows for a policy election to account for forfeitures as they occur rather than on an estimated basis. ASU No. 2016-09 was adopted early by the Company for the quarter ended December 31, 2016 and was applied retrospectively to all periods presented. The adoption of this guidance did not have a material impact on the Company's consolidated financial statements for all periods presented. In October 2016, the FASB issued ASU No. 2016-16, "Income Taxes (Topic 740): Intra-Entity Transfers of Assets Other Than Inventory." ASU No. 2016-16 removes the prohibition in ASC 740 against the immediate recognition of the current and deferred income tax effects of intra-entity transfers of assets other than inventory. ASU No. 2016-16 was adopted early by the Company for the quarter ended December 31, 2016 and was applied on a modified retrospective basis to all periods presented. The adoption of this guidance resulted in a cumulative adjustment to equity of $61 million . Recently Issued Accounting Pronouncements In January 2017, the FASB issued ASU No. 2017-04, "Intangibles-Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment." ASU No. 2017-04 simplifies how an entity is required to test goodwill for impairment by eliminating Step 2 from the goodwill impairment test. Step 2 measures a goodwill impairment loss by comparing the implied fair value of a reporting unit's goodwill with the carrying amount of that goodwill. ASU No. 2017-04 will be effective for the Company for the quarter ending December 31, 2020, with early adoption permitted. The Company is currently assessing the impact adoption of this guidance will have on its consolidated financial statements. In January 2017, the FASB issued ASU No. 2017-01, "Business Combinations (Topic 805): Clarifying the Definition of a Business." ASU No. 2017-01 clarifies the definition of a business as it relates to the acquisition or sale of assets or businesses. ASU No. 2017-01 will be effective for the Company for the quarter ending December 31, 2018, with early adoption permitted. The Company is currently assessing the impact adoption of this guidance will have on its consolidated financial statements. In November 2016, the FASB issued ASU No. 2016-18, "Statement of Cash Flows (Topic 230): Restricted Cash." ASU No. 2016-18 clarifies the classification and presentation of restricted cash on the statement of cash flows. ASU No. 2016-18 will be effective for the Company for the quarter ending December 31, 2018, with early adoption permitted. The Company is currently assessing the impact adoption of this guidance will have on its consolidated statement of cash flows.

Product Warranties Disclosures [Abstract]
Product Warranty Disclosure [Text Block]	Note 4. PRODUCT WARRANTIES The Company offers warranties to its customers depending upon the specific product and terms of the customer purchase agreement. A typical warranty program requires that the Company replace defective products within a specified time period from the date of sale. The Company records an estimate for future warranty-related costs based on actual historical return rates and other known factors. Based on analysis of return rates and other factors, the Company's warranty provisions are adjusted as necessary. The Company monitors its warranty activity and adjusts its reserve estimates when it is probable that future warranty costs will be different than those estimates. The Company's product warranty liability is recorded in the consolidated statements of financial position in other current liabilities. The changes in the Company's total product warranty liability are as follows: Three Months Ended (in millions) 2016 2015 Balance at beginning of period $ 13 $ 12 Accruals for warranties issued during the period 1 2 Changes in accruals related to pre-existing warranties (including changes in estimates) 4 (2 ) Settlements made (in cash or in kind) during the period (3 ) (1 ) Balance at end of period $ 15 $ 11

The Credit Facilities mature on July 27, 2021. Commencing March 31, 2017 until the Term Loan A maturity date, amortization of the funded Term Loan A shall be required in an amount per quarter equal to 0.625% of the original principal amount in the first year following the closing date of the credit facilities (July 27, 2016, "the Closing Date"), 1.25% in each quarter of the second and third years following the Closing Date, and 2.50% in each quarter thereafter prior to final maturity. The credit facility contains covenants that include, among other things and subject to certain significant exceptions, restrictions on Adient's ability to declare or pay dividends, make certain payments in respect of the notes, create liens, incur additional indebtedness, make investments, engage in transactions with affiliates, enter into agreements restricting Adient's subsidiaries' ability to pay dividends, dispose of assets and merge or consolidate with any other person. In addition, the credit facilities contain a financial maintenance covenant requiring Adient to maintain a total net leverage ratio equal to or less than 3.5x adjusted EBITDA, calculated on a quarterly basis. The Term Loan A Facility also requires mandatory prepayments in connection with certain non-ordinary course asset sales and insurance recovery and condemnation events, among other things, and subject in each case to certain significant exceptions. The full amount of the Term Loan A facility was drawn down in the fourth quarter of fiscal 2016. These funds were transferred to JCI at the time of the draw down and reflected within net transfers to parent in the consolidated statement of cash flow during the fourth quarter of fiscal 2016. The drawn portion of the Credit Facilities bear interest based on LIBOR plus a margin between 1.25% - 2.25%, based on Adient's total net leverage ratio. AGH will pay a commitment fee on the unused portion of the commitments under the revolving credit facility based on the total net leverage ratio of Adient, ranging from 0.15% to 0.35% . No amounts were outstanding or drawn under the revolving credit facility at or for the three months ended December 31, 2016. On August 19, 2016, AGH issued $0.9 billion aggregate principal amount of 4.875% USD-denominated unsecured notes due 2026 and €1.0 billion aggregate principal amount of 3.50% euro-denominated unsecured notes due 2024, in a private offering exempt from the registration requirements of the Securities Act of 1933, as amended. The proceeds of the notes were used, together with borrowings from the new credit facilities, to pay a distribution to JCI with the remaining proceeds to be used for working capital and general corporate purposes.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Instruments and Hedging Activities Disclosure [Text Block]	Note 6. DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES The Company selectively uses derivative instruments to reduce Adient's market risk associated with changes in foreign currency. Under the Company's policy, the use of derivatives is restricted to those intended for hedging purposes; the use of any derivative instrument for speculative purposes is strictly prohibited. A description of each type of derivative utilized to manage Adient's risk is included in the following paragraphs. In addition, refer to Note 7, "Fair Value Measurements," of the notes to consolidated financial statements for information related to the fair value measurements and valuation methods utilized by the Company for each derivative type. The Company has global operations and participates in the foreign exchange markets to minimize its risk of loss from fluctuations in foreign currency exchange rates. Adient primarily uses foreign currency exchange contracts to hedge certain foreign exchange rate exposures. Adient hedges 70% to 90% of the nominal amount of each of its known foreign exchange transactional exposures. Gains and losses on derivative contracts offset gains and losses on underlying foreign currency exposures. These contracts have been designated as cash flow hedges under ASC 815, "Derivatives and Hedging," and the effective portion of the hedge gains or losses due to changes in fair value are initially recorded as a component of accumulated other comprehensive income (AOCI) and are subsequently reclassified into earnings when the hedged transactions occur and affect earnings. Any ineffective portion of the hedge is reflected in the consolidated statements of income. These contracts were highly effective in hedging the variability in future cash flows attributable to changes in currency exchange rates at December 31, 2016 and September 30, 2016 . The Company selectively uses equity swaps to reduce market risk associated with certain of its stock-based compensation plans, such as its deferred compensation plans. The equity swaps are recorded at fair value. Changes in fair value of the equity swaps are reflected in the consolidated statements of income within selling, general and administrative expenses. At December 31, 2016 , the €1.0 billion aggregate principal amount of 3.5% euro-denominated unsecured notes due 2024 were designated as a net investment hedge to selectively hedge portions of the Company's net investment in Europe. In conjunction with the separation, the currency effects of Adient's euro denominated bonds are reflected in the accumulated other comprehensive income account within invested equity attributable to Adient where they offset gains and losses recorded on Adient's net investment in Europe. The following table presents the location and fair values of derivative instruments and other amounts used in hedging activities included in the Company's consolidated statements of financial position: Derivatives and Hedging Activities Designated as Hedging Instruments under ASC 815 Derivatives and Hedging Activities Not Designated as Hedging Instruments under ASC 815 (in millions) December 31, September 30, December 31, September 30, Other current assets Foreign currency exchange derivatives $ 7 $ 9 $ 16 $ 40 Other noncurrent assets Equity swaps — — 3 — Total assets $ 7 $ 9 $ 19 $ 40 Other current liabilities Foreign currency exchange derivatives $ 31 $ 31 $ 4 $ 8 Equity swaps — — 2 — Long-term debt Foreign currency denominated debt 1,052 1,119 — — Total liabilities $ 1,083 $ 1,150 $ 6 $ 8 The Company enters into International Swaps and Derivatives Associations (ISDA) master netting agreements with counterparties that permit the net settlement of amounts owed under the derivative contracts. The master netting agreements generally provide for net settlement of all outstanding contracts with a counterparty in the case of an event of default or a termination event. The Company has not elected to offset the fair value positions of the derivative contracts recorded in the consolidated statements of financial position. Collateral is generally not required of the Company or the counterparties under the master netting agreements. As of December 31, 2016 and September 30, 2016 , no cash collateral was received or pledged under the master netting agreements. The gross and net amounts of derivative instruments and other amounts used in hedging activities are as follows: Assets Liabilities (in millions) December 31, September 30, December 31, September 30, Gross amount recognized $ 26 $ 49 $ 1,089 $ 1,158 Gross amount eligible for offsetting (5 ) (1 ) (5 ) (1 ) Net amount $ 21 $ 48 $ 1,084 $ 1,157 The following table presents the effective portion of pretax gains (losses) recorded in other comprehensive income related to cash flow hedges: (in millions) Three Months Ended 2016 2015 Foreign currency exchange derivatives $ (7 ) $ (4 ) The following table presents the location and amount of the effective portion of pretax gains (losses) on cash flow hedges reclassified from AOCI into the Company's consolidated statements of income: (in millions) Three Months Ended 2016 2015 Foreign currency exchange derivatives Cost of sales $ (3 ) $ (5 ) The following table presents the location and amount of pretax gains (losses) on derivatives not designated as hedging instruments recognized in the Company's consolidated statements of income: (in millions) Three Months Ended 2016 2015 Foreign currency exchange derivatives Cost of sales $ (14 ) $ (4 ) Foreign currency exchange derivatives Net financing charges 31 7 Equity swap Selling, general and administrative (1 ) — Total $ 16 $ 3 The effective portion of pretax gains recorded in currency translation adjustment (CTA) within other comprehensive income (loss) related to net investment hedges was $67 million for the three months ended December 31, 2016 and no gains or losses were recorded for the three months ended December 31, 2015 . For the three months ended December 31, 2016 and 2015 , no gains or losses were reclassified from CTA into income for the Company's outstanding net investment hedges, and no gains or losses were recognized in income for the ineffective portion of cash flow hedges.

Fair Value Disclosures [Abstract]
Fair Value Disclosures [Text Block]	Note 7. FAIR VALUE MEASUREMENTS ASC 820, "Fair Value Measurement," defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. ASC 820 also establishes a three-level fair value hierarchy that prioritizes information used in developing assumptions when pricing an asset or liability as follows: Level 1: Observable inputs such as quoted prices in active markets; Level 2: Inputs, other than quoted prices in active markets, that are observable either directly or indirectly; and Level 3: Unobservable inputs where there is little or no market data, which requires the reporting entity to develop its own assumptions. ASC 820 requires the use of observable market data, when available, in making fair value measurements. When inputs used to measure fair value fall within different levels of the hierarchy, the level within which the fair value measurement is categorized is based on the lowest level input that is significant to the fair value measurement. Recurring Fair Value Measurements The following tables present the Company's fair value hierarchy for those assets and liabilities measured at fair value: Fair Value Measurements Using: (in millions) Total as of December 31, 2016 Quoted Prices in Active Markets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Other current assets Foreign currency exchange derivatives $ 23 $ — $ 23 $ — Other noncurrent assets Equity swaps 3 — 3 — Total assets $ 26 $ — $ 26 $ — Other current liabilities Foreign currency exchange derivatives $ 35 $ — $ 35 $ — Equity swaps 2 — 2 — Total liabilities $ 37 $ — $ 37 $ — Fair Value Measurements Using: (in millions) Total as of September 30, 2016 Quoted Prices in Active Markets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Other current assets Foreign currency exchange derivatives $ 49 $ — $ 49 $ — Total assets $ 49 $ — $ 49 $ — Other current liabilities Foreign currency exchange derivatives $ 39 $ — $ 39 $ — Total liabilities $ 39 $ — $ 39 $ — Valuation Methods Foreign currency exchange derivatives The Company selectively hedges anticipated transactions that are subject to foreign exchange rate risk primarily using foreign currency exchange hedge contracts. The foreign currency exchange derivatives are valued under a market approach using publicized spot and forward prices. Changes in fair value on foreign exchange derivatives accounted for as hedging instruments under ASC 815 are initially recorded as a component of AOCI and are subsequently reclassified into earnings when the hedged transactions occur and affect earnings. The changes in fair value of foreign currency exchange derivatives not designated as hedging instruments under ASC 815 are recorded in the consolidated statements of income. Equity swaps The Company selectively uses equity swaps to reduce market risk associated with certain of its stock-based compensation plans, such as its deferred compensation plans. The equity swaps are recorded at fair value. Changes in fair value of the equity swaps are reflected in the consolidated statements of income within selling, general and administrative expenses.

Share-based Compensation [Abstract]
Disclosure of Compensation Related Costs, Share-based Payments [Text Block]	Note 8. STOCK-BASED COMPENSATION During the three months ended December 31, 2016 , the Company provided certain key employees equity awards in the form of performance share units (PSUs) and restricted stock units (RSUs) under the Adient plc 2016 Omnibus Incentive Plan and provided directors with share awards under the Adient plc 2016 Director Share Plan. These plans were adopted in conjunction with the separation. Total cash and non-cash stock-based compensation cost included in the consolidated statements of income was $6 million and $1 million for the three months ended December 31, 2016 and 2015 , respectively. Stock-based compensation expense prior to the separation was allocated to Adient based on the portion of Adient's equity compensation programs in which Adient employees participated. In conjunction with the separation, previously outstanding stock-based compensation awards granted under JCI's equity compensation programs prior to the separation and held by certain executives and employees of Adient were adjusted and converted into new equity awards using a formula designated to preserve the intrinsic value of the awards. Upon the separation on October 31, 2016, holders of JCI stock, stock options, RSUs, and SARs generally received one ordinary share of Adient for every ten ordinary shares of JCI held at the close of business on October 19, 2016, the record date of the distribution, and cash in lieu of fractional shares (if any) of Adient. Accordingly, certain executives and employees of Adient hold converted awards in both JCI and Adient shares subsequent to the separation. Converted awards retained the vesting schedule and expiration date of the original awards. Outstanding stock awards related to JCI stock are not included in the Company's dilutive share calculation. The following tables present activity related to the conversion and granting of awards during the three months ended December 31, 2016 along with the composition of outstanding and exercisable awards at December 31, 2016 for remaining JCI and new Adient awards.

Restructuring and Related Activities [Abstract]
Restructuring and Related Activities Disclosure [Text Block]	Note 10. SIGNIFICANT RESTRUCTURING AND IMPAIRMENT COSTS To better align its resources with its growth strategies and reduce the cost structure of its global operations to address the softness in certain underlying markets, the Company commits to restructuring plans as necessary. In fiscal 2016, the Company committed to a significant restructuring plan (2016 Plan) and recorded $332 million of restructuring and impairment costs in the consolidated statements of income. This is the total amount incurred to date and the total amount expected to be incurred for this restructuring plan. The restructuring actions relate to cost reduction initiatives. The costs consist primarily of workforce reductions, plant closures, asset impairments, and changes in estimates to prior year plans. Of the restructuring and impairment costs recorded, $315 million relates to the Seating segment and $17 million relates to the Interiors segment. The asset impairment charge recorded during fiscal 2016 relates primarily to information technology assets within the Seating segment that will not be used going forward by the Company. The other charges recorded in fiscal 2016 of $22 million relate primarily to restructuring costs at one of the Company's joint ventures which the Company has indemnified. The restructuring actions are expected to be substantially complete in fiscal 2018. The following table summarizes the changes in the Company's 2016 Plan reserve: (in millions) Employee Severance and Termination Benefits Long-Lived Asset Impairments Other Currency Total Original Reserve $ 223 $ 87 $ 22 $ — $ 332 Utilized—cash (29 ) — (1 ) — (30 ) Utilized—noncash — (87 ) — (2 ) (89 ) Balance at September 30, 2016 194 — 21 (2 ) 213 Utilized—cash (4 ) — (12 ) — (16 ) Utilized—noncash — — — (10 ) (10 ) Balance at December 31, 2016 $ 190 $ — $ 9 $ (12 ) $ 187 In fiscal 2015, the Company committed to a significant restructuring plan (2015 Plan) and recorded $182 million of restructuring and impairment costs in the consolidated statements of income. This is the total amount incurred to date and the total amount expected to be incurred for this restructuring plan. The restructuring actions relate to cost reduction initiatives. The costs consist primarily of workforce reductions, plant closures and asset impairments. The restructuring and impairment costs related to the Seating segment. The restructuring actions are expected to be substantially complete in fiscal 2017. The following table summarizes the changes in the Company's 2015 Plan reserve: (in millions) Employee Severance and Termination Benefits Long-Lived Asset Impairments Currency Total Original Reserve $ 155 $ 27 $ — $ 182 Utilized—cash (1 ) — — (1 ) Utilized—noncash — (27 ) — (27 ) Balance at September 30, 2015 154 — — 154 Utilized—cash (41 ) — — (41 ) Utilized—noncash — — (1 ) (1 ) Balance at September 30, 2016 113 — (1 ) 112 Utilized—cash (22 ) — — (22 ) Utilized—noncash — — (7 ) (7 ) Balance at December 31, 2016 $ 91 $ — $ (8 ) $ 83 The Company's fiscal 2016 and 2015 restructuring plans included workforce reductions of approximately 5,000 . Restructuring charges associated with employee severance and termination benefits are paid over the severance period granted to each employee or on a lump sum basis in accordance with individual severance agreements. As of December 31, 2016 , approximately 1,900 of the employees have been separated from the Company pursuant to the restructuring plans. In addition, the restructuring plans included thirteen plant closures. As of December 31, 2016 , seven of the thirteen plants have been closed. Company management closely monitors its overall cost structure and continually analyzes each of its businesses for opportunities to consolidate current operations, improve operating efficiencies and locate facilities in low cost countries in close proximity to customers. This ongoing analysis includes a review of its manufacturing, engineering, purchasing and administrative functions, as well as the overall global footprint for all its businesses. Because of the importance of new vehicle sales by major automotive manufacturers to operations, the Company is affected by the general business conditions in this industry. Future adverse developments in the automotive industry could impact the Company's liquidity position, lead to impairment charges and/or require additional restructuring of its operations.

Income Tax Disclosure [Abstract]
Income Tax Disclosure [Text Block]	In calculating the provision for income taxes, the Company uses an estimate of the annual effective tax rate based upon the facts and circumstances known at each interim period. On a quarterly basis, the actual effective tax rate is adjusted, as appropriate, based on changes in facts and circumstances, if any, as compared to those forecasted at the beginning of the fiscal year and each interim period thereafter. For the three months ended December 31, 2016, the Company’s effective tax rate was 14% . The effective rate benefited from global tax planning and foreign tax rate differentials, partially offset by a tax law change in Hungary. For the three months ended December 31, 2015, the Company’s effective tax rate was 26% . The effective rate benefited from global tax planning and foreign tax rate differentials. Uncertain Tax Positions Prior to separation, the Company and JCI entered into a tax matters agreement that governs the parties respective rights and obligations with respect to certain tax attributes, including uncertain tax positions. As a result of the final tax matters agreement, the Company's unrecognized tax benefits decreased approximately $470 million from September 30, 2016. At December 31, 2016, the Company had gross tax effected unrecognized tax benefits of $119 million , essentially all of which, if recognized, would impact the effective tax rate. Total net accrued interest at December 31, 2016 was approximately $11 million (net of tax benefit). The interest and penalties accrued during the three months ended December 31, 2016 and 2015 was not material. The Company recognizes interest and penalties related to unrecognized tax benefits as a component of income tax expense. Impacts of Tax Legislation and Change in Statutory Tax Rates During the three months ended December 31, 2016, Hungary passed the 2017 tax bill which reduced the corporate income tax rate to a flat 9% rate. As a result of the law change, the Company recorded income tax expense of $5 million related to the write down of deferred tax assets. Other tax legislation was adopted during the quarter in various jurisdictions, which did not have a material impact on the Company’s consolidated financial statements.

Segment Reporting [Abstract]
Segment Reporting Disclosure [Text Block]	Note 12. SEGMENT INFORMATION During the three months ended December 31, 2016, the Company began evaluating the performance of its reportable segments using an adjusted EBIT metric defined as income before income taxes and noncontrolling interests, excluding net financing charges, qualified restructuring and impairment costs, restructuring related-costs, non-recurring "Becoming Adient" costs (formerly separation costs), net mark-to-market adjustments on pension and postretirement plans, transaction gains/losses, purchase accounting amortization and other non-recurring items ("Adjusted EBIT"). Prior period information has been recast to this new performance metric. The reportable segments are consistent with how management views the markets served by the Company and reflect the financial information that is reviewed by its chief operating decision maker. The Company has two reportable segments for financial reporting purposes: Seating and Interiors. • The Seating segment produces automotive seat metal structures and mechanisms, foam, trim, fabric and complete seat systems. • The Interiors segment, derived from its global automotive interiors joint ventures, produces instrument panels, floor consoles, door panels, overhead consoles, cockpit systems, decorative trim and other products. Prior period information has been recast to conform to current performance metrics. Financial information relating to the Company's reportable segments is as follows: Three Months Ended (in millions) 2016 2015 Net Sales Seating $ 4,038 $ 4,233 Total net sales $ 4,038 $ 4,233 Three Months Ended (in millions) 2016 2015 Adjusted EBIT Seating $ 260 $ 237 Interiors 30 24 Becoming Adient/separation costs (1) (41 ) (60 ) Purchase accounting amortization (2) (10 ) (9 ) Restructuring related charges (3) (5 ) (4 ) Other items (4) — 21 Earnings before interest and income taxes 234 209 Net financing charges (35 ) (2 ) Income before income taxes $ 199 $ 207 (1) Reflects incremental/non-recurring expenses associated with becoming an independent company and expenses associated with the separation from the former Parent.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies Disclosure [Text Block]	Note 14. COMMITMENTS AND CONTINGENCIES The Company accrues for potential environmental liabilities when it is probable a liability has been incurred and the amount of the liability is reasonably estimable. Reserves for environmental liabilities totaled $7 million and $6 million at December 31, 2016 and September 30, 2016 , respectively. The Company reviews the status of its environmental sites on a quarterly basis and adjusts its reserves accordingly. Such potential liabilities accrued by the Company do not take into consideration possible recoveries of future insurance proceeds. They do, however, take into account the likely share other parties will bear at remediation sites. It is difficult to estimate the Company's ultimate level of liability at many remediation sites due to the large number of other parties that may be involved, the complexity of determining the relative liability among those parties, the uncertainty as to the nature and scope of the investigations and remediation to be conducted, the uncertainty in the application of law and risk assessment, the various choices and costs associated with diverse technologies that may be used in corrective actions at the sites, and the often quite lengthy periods over which eventual remediation may occur. Nevertheless, the Company does not currently believe that any claims, penalties or costs in connection with known environmental matters will have a material adverse effect on the Company's financial position, results of operations or cash flows. The Company is involved in various lawsuits, claims and proceedings incident to the operation of its businesses, including those pertaining to product liability, environmental, safety and health, intellectual property, employment, commercial and contractual matters, and various other casualty matters. Although the outcome of any such lawsuit, claim or proceeding cannot be predicted with certainty and some may be disposed of unfavorably to Adient, it is management's opinion that none of these will have a material adverse effect on the Company's financial position, results of operations or cash flows. Costs related to such matters were not material to the periods presented.

Related Party Transactions [Abstract]
Related Party Transactions Disclosure [Text Block]	Note 15. RELATED PARTY TRANSACTIONS Related Party Transactions In the ordinary course of business, the Company enters into transactions with related parties, such as equity affiliates. Such transactions consist of facility management services, the sale or purchase of goods and other arrangements. Subsequent to the separation, transactions with Johnson Controls and its businesses represent third-party transactions. Revision of Previously Reported Related Party Transactions The Company previously identified misstatements in amounts classified as related party transactions in previously reported periods. The misstatements impacted the amounts previously disclosed in this footnote. The misstatements are not considered material, individually or in the aggregate, to previously issued financial statements. The misstatements had no impact on the consolidated financial statements. The following table sets forth the net sales to and purchases from related parties included in the consolidated statements of income: Three Months Ended (in millions) 2016 2015 Net sales to related parties $ 98 $ 113 (1) Purchases from related parties 100 106 (1) (1) These amounts have been revised to correct for previously reported misstatements. The revisions increased net sales to related parties by $27 million and increased purchases from related parties by $70 million for three months ended December 31, 2015 . The following table sets forth the amount of accounts receivable due from and payable to related parties in the consolidated statements of financial position: (in millions) December 31, September 30, Receivable from related parties $ 151 $ 172 Payable to related parties 95 96 Excluding the settlement of intercompany balances in advance of the separation of the Company from JCI, average receivable and payable balances with related parties remained consistent with the period end balances shown above. Allocations from Former Parent Prior to the separation, the consolidated statements of income included allocations for certain support functions that were provided on a centralized basis by Johnson Controls and subsequently recorded at the business unit level, such as expenses related to employee benefits, finance, human resources, risk management, information technology, facilities, and legal, among others. Included in cost of sales and selling, general and administrative expense during the three months ended December 31, 2015 were $70 million , of corporate expenses incurred by the former Parent. In addition to these allocations, approximately $87 million of costs related to the separation of Adient were incurred by the former Parent for the three months ended December 31, 2015 . Of this amount, $60 million was deemed to directly benefit Adient as a stand-alone company. Accordingly, these costs were allocated to Adient and are reflected within selling, general and administrative expenses in the consolidated statements of income for the three months ended December 31, 2015 . Additionally, certain intercompany transactions prior to the separation between the Company and the former Parent have not been recorded as related party transactions. These transactions were considered to be effectively settled for cash at the time the transaction was recorded. The total net effect of the settlement of these intercompany transactions was reflected in the consolidated statements of cash flows as a financing activity and in the consolidated statements of financial position as Parent's net investment. During the three months ended December 31, 2016, the allocations from the former Parent were insignificant. The Company and JCI are still finalizing the reconciliation of working capital and other accounts and the net due to/from JCI will be settled later in fiscal 2017 in accordance with the separation agreement. The impact of the settlement will be reflected within additional paid-in capital.

Variable Interest Entity [Line Items]
Variable Interest Entity Disclosure [Text Block]	Consolidated VIEs Based upon the criteria set forth in Financial Accounting Standards Board (FASB) Accounting Standards Codification (ASC) 810, "Consolidation," the Company has determined that it was the primary beneficiary in two variable interest entities (VIEs) for the reporting periods ended December 31, 2016 and September 30, 2016 , as the Company absorbs significant economics of the entities and has the power to direct the activities that are considered most significant to the entities. The two VIEs manufacture seating products in North America for the automotive industry. The Company funds the entities' short-term liquidity needs through revolving credit facilities and has the power to direct the activities that are considered most significant to the entities through its key customer supply relationships.
Basis of Presentation and Significant Accounting Policies [Text Block]	Basis of Presentation The financial statements for periods prior to October 31, 2016 were prepared on a stand-alone combined basis derived from the consolidated financial statements and accounting records of JCI as if Adient had been operating as a stand-alone company for all periods presented. These financial statements have been prepared in accordance with generally accepted accounting principles in the United States of America ("U.S. GAAP"). The assets and liabilities in the financial statements have been reflected on a historical cost basis, as included in the consolidated statements of financial position of JCI. The statements of income include allocations for certain support functions that were provided on a centralized basis by the former Parent and subsequently recorded at the business unit level, such as expenses related to employee benefits, finance, human resources, risk management, information technology, facilities, and legal, among others. These expenses have been allocated to the Company on the basis of direct usage when identifiable, with the remainder allocated on a proportional basis of combined sales, headcount or other measures of the Company or the Parent. Management believes the assumptions underlying the financial statements, including the assumptions regarding allocating general corporate expenses from JCI, are reasonable. Nevertheless, the financial statements for periods prior to the separation may not include all actual expenses that would have been incurred by Adient and may not reflect the results of operations, financial position and cash flows had it been a stand-alone company during the periods presented. Actual costs that would have been incurred if Adient had been a stand-alone company would depend on multiple factors, including organizational structure and strategic decisions made in various areas, including information technology and infrastructure. The financial statements for periods prior to the separation include certain assets and liabilities that have historically been held at JCI but are specifically identifiable or otherwise attributable to Adient. All significant intercompany transactions and accounts within the Company's businesses have been eliminated. All intercompany transactions between the Company and JCI prior to the separation have been included in the consolidated financial statements as Parent's net investment. Expenses related to corporate allocations from JCI to the Company are considered to be effectively settled for cash in the financial statements at the time the transaction is recorded. In addition, transactions between the Company and JCI's other businesses prior to the separation have been classified as related party, rather than intercompany, in the financial statements. See Note 15, "Related Party Transactions and Parent's Net Investment," of the notes to consolidated financial statements for further details. Prior to the separation, transfers of cash to and from JCI's cash management system were reflected as a component of Parent's net investment in the consolidated statements of financial position. For periods prior to the separation, the cash and cash equivalents held by JCI were not attributed to the Company, as legal ownership remained with the former Parent. Furthermore, the income tax expense and deferred taxes in the financial statements for periods prior to October 31, 2016 were prepared on a separate return basis derived from the consolidated financial statements and accounting records of JCI as if Adient had been operating as a stand-alone company for all periods presented. As a standalone entity, Adient will file tax returns on its own behalf and its effective tax rate and deferred taxes may differ from those in historical periods. The accompanying consolidated financial statements presented herein are unaudited and should be read in conjunction with the combined financial statements presented in the Company's 2016 Annual Report on Form 10-K. These consolidated financial statements have been prepared in accordance with U.S. GAAP. Such financial statements reflect all adjustments that, in the opinion of management, are necessary for a fair statement of the results of the interim periods presented; all such adjustments are of a normal recurring nature except for the impacts of adopting new accounting standards as discussed below. All significant intercompany accounts and transactions have been eliminated. The results of operations for the three months ended December 31, 2016 are not necessarily indicative of the results of operations for the year ending September 30, 2017. In addition to wholly-owned subsidiaries, the Company has investments which, in certain cases, may or may not require combination, as a result of only a partial-ownership interest and/or lack of significant influence over the investee. The Company's investments in partially-owned affiliates are accounted for by the equity method when the Company's interest exceeds 20% and the Company does not have a controlling interest.

Cash and Cash Equivalents, Restricted Cash and Cash Equivalents, Policy [Policy Text Block]	Restricted Cash At September 30, 2016, the Company recorded $2 billion of restricted cash within the consolidated statements of financial position. These funds represent the proceeds from the bond issuance which were placed directly into escrow and released to the Company subsequent to September 30, 2016 and therefore represents non-cash activity in fiscal 2016. The cash was used during the three months ended December 31, 2016 in part, to fund a distribution to Johnson Controls. The $2 billion receipt of cash from escrow, along with the distribution to and other settlements with the former Parent during the three months ended December 31, 2016 are reflected in net transfers from parent in the consolidated statement of cash flows. Refer to Note 5, "Debt and Financing Arrangements," of the notes to the consolidated financial statements for further information on the bond issuance.
