Basis of Presentation [Abstract]
Basis of Presentation	(1) Basis of Presentation The accompanying condensed consolidated financial statements have been prepared by Stoneridge, Inc. (the “Company”) without audit, pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”). The information furnished in the condensed consolidated financial statements includes normal recurring adjustments and reflects all adjustments, which are, in the opinion of management, necessary for a fair presentation of such financial statements. Certain information and footnote disclosures normally included in financial statements prepared in accordance with U.S. generally accepted accounting principles have been condensed or omitted pursuant to the SEC's rules and regulations. The results of operations for the three months ended March 31, 2017 are not necessarily indicative of the results to be expected for the full year. While the Company believes that the disclosures are adequate to make the information presented not misleading, it is suggested that these condensed consolidated financial statements be read in conjunction with the audited consolidated financial statements and the notes thereto included in the Company's 2016 Form 10-K.  On January 31, 2017, the Company acquired Exploitatiemaatschappij Berghaaf B.V. (“Orlaco”), an electronics business which designs, manufactures and sells a variety of camera-based vision systems, monitors and related products. As such, the Company’s condensed consolidated financial statements herein include the results of Orlaco from the acquisition date to March 31, 2017. See Note 3 to the condensed consolidated financial statements for additional details regarding the Orlaco acquisition.  Also, see the impact of the adoption of various accounting standards below on the condensed consolidated financial statements herein.

Recently Issued Accounting Standards [Abstract]
Recently Issued Accounting Standards	(2) Recently Issued Accounting Standards  Recently Adopted Accounting Standards  In January 2017, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2017-04, “Simplifying the Test for Goodwill Impairment.” It eliminates Step 2 from the goodwill impairment test. As a result, an entity should recognize an impairment charge for the amount by which the carrying amount of goodwill exceeds the reporting unit's fair value, not to exceed the carrying amount of goodwill. The Company adopted this standard on January 1, 2017 which did not have an impact on its condensed consolidated financial statements.  In March 2016, the FASB issued ASU 2016-09, “Compensation - Stock Compensation (Topic 718)” which is intended to simplify several aspects of the accounting for share-based payment award transactions including how excess tax benefits should be classified in the Company’s condensed consolidated financial statements. The new standard simplifies the treatment of share based payment transactions by recognizing the impact of excess tax benefits or deficiencies related to exercised or vested awards in income tax expense in the period of exercise or vesting. The new standard also modifies the diluted earnings per share calculation using the treasury stock method by eliminating the excess tax benefits or deficiencies from the calculation. These changes have been recognized prospectively. The presentation of excess tax benefits in the condensed statement of consolidated cash flows is also modified to be included with other income tax cash flows as an operating activity. The Company adopted this standard as of January 1, 2017 utilizing the prospective transition method for excess tax benefits in the condensed consolidated statement of cash flows . The Company had unrecognized tax benefits related to share-based payment awards of $1,7 29 as of December 31, 2016 which upon adoption was recorded in other long-term assets with a corresponding increase to retained earnings associated with the cumulative effect of the accounting change.  In July 2015, the FASB issued ASU 2015-11 “Simplifying the Measurement of Inventory” which requires that inventory be measured at the lower of cost or net realizable value. Prior to the issuance of the new guidance, inventory was measured at the lower of cost or market. Replacing the concept of market with the single measurement of net realizable value is intended to reduce cost and complexity. The Company adopted this standard as of January 1, 2017, which did not have a material impact on the Company’s condensed consolidated financial statements or disclosures.   Accounting Standards Not Yet Adopted In January 2017, the FASB issued ASU 2017-01, “Clarifying the Definition of a Business”. It revises the definition of a business and provides a framework to evaluate when an input and a substantive process are present in an acquisition to be considered a business. This guidance is effective for annual periods beginning after December 15, 2017. The Company expects to adopt this standard as of January 1, 2018, which is not expected to have any impact on its condensed consolidated financial statements. In August 2016, the FASB issued ASU 2016-15, “Statement of Cash Flows - Classification of Certain Cash Receipts and Cash Payments (Topic 230)” which provides guidance on the presentation and classification of certain cash receipts and cash payments in the statement of cash flows in order to reduce diversity in practice. This ASU is effective for interim and annual periods beginning after December 15, 2017 with early adoption permitted. The Company is currently evaluating the impact of adopting this standard on its condensed consolidated financial statements. In February 2016, the FASB issued ASU 2016-02, “Leases (Topic 842)”, which will require that a lessee recognize assets and liabilities on the balance sheet for all leases with a lease term of more than twelve months, with the result being the recognition of a right of use asset and a lease liability. The amendment is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018. The Company expects to adopt this standard as of January 1, 2019. The Company is currently evaluating the impact of adopting this standard on its condensed consolidated financial statements, which will require right of use assets and lease liabilities be recorded in the condensed consolidated balance sheet for operating leases. In May 2014, the FASB issued ASU 2014-09 “Revenue from Contracts with Customers,” which is the new comprehensive revenue recognition standard that will supersede existing revenue recognition guidance under U.S. GAAP. The standard's core principle is that a company will recognize revenue when it transfers promised goods or services to a customer in an amount that reflects the consideration to which the company 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. This ASU allows for both retrospective and prospective methods of adoption. The new standard will become effective for annual and interim periods beginning after December 15, 2017 with early adoption permitted. The Company is currently evaluating the impact of adopting this standard on its condensed consolidated financial statements, and anticipate testing our new controls and processes designed to comply with the standard in 2017 to permit the Company’s adoption on January 1, 2018. The Company is evaluating changes to revenue recognition of pre-production activities such as customer funded tooling and engineering design and development cost recoveries, including the potential recording of these as revenue.

Acquisition of Orlaco [Abstract]
Acquisition of Orlaco	(3) Acquisition of Orlaco  On January 31, 2017 , Stoneridge B.V., an indirect wholly-owned subsidiary of Stoneridge, Inc., entered into and closed an agreement to acquire Orlaco. Orlaco designs, manufactures and sells a variety of camera-based vision systems, monitors and related electronic products primarily to the heavy off-road machinery, commercial vehicle, lifting crane and warehousing and logistics industries. Since July 2015, Stoneridge and Orlaco have jointly developed the MirrorEye mirror replacement system, which is a system solution to improve the safety and fuel economy of commercial vehicles. The MirrorEye system integrates Orlaco’s camera technology and Stoneridge’s driver information capabilities as well as the combined software capabilities of both companies. The acquisition of Orlaco enhances the Stoneridge’s Electronics segment global technical capabilities in vision systems and facilitates entry into new markets.    The aggregate consideration for the Orlaco acquisition was €74,939 ( $79,675 ), which included customary estimated adjustments to the purchase price. The Company paid €67,439 ( $71,701 ) in cash, and €7,500 ( $7,974 ) is held in an escrow account to secure the payment obligations of the seller under the terms of the purchase agreement. The purchase price is subject to certain customary adjustments set forth in the purchase agreement. The escrow amount will be transferred promptly following the completion of the escrow period. The Company may also be required pay up to an additional €7,500 as earnout consideration if certain targets are achieved during the first two years.  The acquisition date fair value of the total consideration transferred consisted of the following:     Cash $ 79,675  Fair value of earn-out liability and other adjustments 5,471  Total purchase price $ 85,146  The following table summarizes the estimated fair values of the assets acquired and liabilities assumed at the acquisition date. The purchase price and associated allocation is preliminary pending completion of the valuation of acquired inventory, property, plant and equipment, intangible assets and deferred income taxes.     At January 31, 2017  Cash $ 2,165  Accounts receivable 8,130  Inventory 9,144  Prepaids and other current assets 298  Property, plant and equipment 6,668  Identifiable intangible assets 38,626  Other long-term assets 690  Total identifiable assets acquired 65,721   Accounts payable 3,020  Other current liabilities 805  Deferred tax liabilities 9,994  Other long-term liabilitites 1,462  Total liabilities assumed 15,281  Net identifiable assets acquired 50,440  Goodwill 34,706  Net assets acquired $ 85,146  Assets acquired and liabilities assumed were recorded at estimated fair values based on management's estimates, available information, and reasonable and supportable assumptions. Also, the Company utilized a third-party to assist with certain estimates of fair values, including: · Fair value estimate for inventory was based on a comparative sales method · Fair value estimate for property, plant and equipment was based on appraised values utilizing cost and market approaches · Fair values for intangible assets were based on a combination of market and income approaches, including the relief from royalty method · Fair value for the earn-out liability was based on a Monte Carlo simulation utilizing forecast ed EBITDA for the 2017 and 2018 measurement period These non-recurring fair value meas urements are classified within L evel 3 of the fair value hierarchy. The preliminary purchase price allocations may be subsequently adjusted to reflect final valuation results and purchase price adjustments . Goodwill is calculated as the excess of the fair value of consideration transferred over the fair market value of the identifiable assets and liabilities and represents the future economic benefits arising from other assets acquired that could not be separately recognized. The goodwill is included in the Company’s Electronics segment and is not deductible for income tax purposes. Of the $38,626 of acquired identifiable intangible assets, $27,405 was provisionally assigned to customer lists with a 15 -year useful life; $5,142 was provisionally assigned to trademarks with a 20 year useful life; and $6,079 was provisionally assigned to technology with a 7 year weighted-average useful life. The Company recognized $1,218 of acquisition related costs in the condensed consolidated statement of operations as a component of selling, general and administrative expense during the three months ended March 31, 2017 . Included in the Company's statement of operations for the three months ended March 31, 2017 are post-acquisition sales of $11,100 and net income of $600 related to Orlaco which are included in the Electronics segment. The Company’s statement of operations for the three months ended March 31, 2017 also included $979 of expense in cost of goods sold associated with the step up of the Orlaco inventory to fair value.  The following unaudited pro forma information reflects the Company’s condensed consolidated results of operations as if the acquisition had taken place on January 1, 2016. The unaudited pro forma information is not necessarily indicative of the results of operations that the Company would have reported had the transaction actually occurred at the beginning of these periods, nor is it necessarily indicative of future results.       Three months ended March 31, 2017 2016  Net sales $ 209,341 $ 177,491  Net income attributable to Stoneridge, Inc. and subsidiaries $ 9,307 $ 8,896  The unaudited pro forma financial information presented in the table above has been adjusted to give effect to adjustments that are directly related to the business combination and are factually supportable. These adjustments include, but are not limited to, depreciation and amortization related to fair value adjustments to property, plant, and equipment and finite-lived intangible assets. Also, an adjustment has been made for management fees expensed by Orlaco.

Inventories [Abstract]
Inventories	              (4) Inventories Inventories are valued at the lower of cost (using either the first-in, first-out (“FIFO”) or average cost methods) or net realizable value. The Company evaluates and adjusts as necessary its excess and obsolescence reserve on a quarterly basis. Excess inventories are quantities of items that exceed anticipated sales or usage for a reasonable period. The Company has guidelines for calculating provisions for excess inventories based on the number of months of inventories on-hand compared to anticipated sales or usage. Management uses its judgment to forecast sales or usage and to determine what constitutes a reasonable period. Inventory cost includes material, labor and overhead. Inventories consisted of the following:    March 31, December 31,  2017 2016  Raw materials $ 42,439 $ 35,665  Work-in-progress 8,138 7,483  Finished goods 22,151 16,969  Total inventories, net $ 72,728 $ 60,117  Inventory valued using the FIFO method was $49,5 82 and $37,765 at March 31, 2017 and December 31, 2016, respectively. Inventory valued using the average cost method was $23,146 and $22,352 at March 31, 2017 and December 31, 2016, respectively.  .

Financial Instruments and Fair Value Measurements [Abstract]
Financial Instruments and Fair Value Measurements	 (6) Financial Instruments and Fair Value Measurements Financial Instruments A financial instrument is cash or a contract that imposes an obligation to deliver, or conveys a right to receive cash or another financial instrument. The carrying values of cash and cash equivalents, accounts receivable and accounts payable are considered to be representative of fair value because of the short maturity of these instruments. Derivative Instruments and Hedging Activities On March 31, 2017, the Company had open foreign currency forward contracts which are used solely for hedging and not for speculative purposes. Management believes that its use of these instruments to reduce risk is in the Company's best interest. The counterparties to these financial instruments are financial institutions with investment grade credit ratings.  Foreign Currency Exchange Rate Risk The Company conducts business internationally and therefore is exposed to foreign currency exchange rate risk. The Company uses derivative financial instruments as cash flow and fair value hedges to manage its exposure to fluctuations in foreign currency exchange rates by reducing the effect of such fluctuations on foreign currency denominated intercompany transactions, inventory purchases and other foreign currency exposures. The currencies hedged by the Company during 2017 and 2016 included the euro and Mexican peso. In addition, the Company hedged the U.S. dollar against the Swedish krona and euro on behalf of its European subsidiaries in 2016. These forward contracts were executed to hedge forecasted transactions and have been accounted for as cash flow hedges. As such, the effective portion of the unrealized gain or loss was deferred and reported in the Company’s condensed consolidated balance sheets as a component of accumulated other comprehensive loss. The cash flow hedges were highly effective. The effectiveness of the transactions has been and will be measured on an ongoing basis using regression analysis and forecasted future purchases of the currency.  In certain instances, the foreign currency forward contracts do not qualify for hedge accounting or are not designated as hedges, and therefore are marked-to-market with gains and losses recognized in the Company's condensed consolidated statement of operations as a component of other expense, net. The Company's foreign currency forward contracts offset a portion of the gains and losses on the underlying foreign currency denominated transactions as follows: Euro-denominated Foreign Currency Forward Contract At March 31, 2017 and December 31, 2016, the Company held a foreign currency forward contract with underlying notional amounts of $1,630 and $1,601 , respectively, to reduce the exposure related to the Company's euro-denominated intercompany loans. The current contract expires in June 2017 . The euro-denominated foreign currency forward contract was not designated as a hedging instrument. The Company recognized a loss of $19 and $8 2 for the three months ended March 31, 2017 and 201 6, respectively, in the condensed consolidated statements of operations as a component of other expense , net related to the euro-denominated contract.     Mexican peso-denominated Foreign Currency Forward Contracts – Cash Flow Hedge The Company holds Mexican peso-denominated foreign currency forward contracts with notional amounts at March 31, 2017 of $4,248 which expire ratably on a monthly basis from April 2017 through December 2017, compared to a notional amount of $5,699 at December 31, 2016.  The Company evaluated the effectiveness of the Mexican peso-denominated foreign currency forward contracts held as of March 31, 2017 and December 31, 2016 and concluded that the hedges were highly effective.   The notional amounts and fair values of derivative instruments in the condensed consolidated balance sheets were as follows:     Prepaid expenses Accrued expenses and  Notional amounts (A) and other current assets other current liabilities  March 31, December 31, March 31, December 31, March 31, December 31,  2017 2016 2017 2016 2017 2016  Derivatives designated as hedging instruments:  Cash flow hedges:  Forward currency contracts $4,248 $5,699 $459 $0 $0 $28  Derivatives not designated as hedging instruments:  Forward currency contracts $1,630 $1,601 $0 $0 $0 $3    (A) Notional amounts represent the gross contract in U.S. dollars of the derivatives outstanding.  Gross amounts recorded for the cash flow hedges in other comprehensive income and in net income for the three months ended March 31 are as follows:     Gain (loss) reclassified from  Gain (loss) recorded in other other comprehensive income  comprehensive income into net income  2017 2016 2017 2016  Derivatives designated as cash flow hedges:  Forward currency contracts $ 516 $ (494) $ 29 $ (44)   Gains and losses reclassified from other comprehensive income into net income were recognized in cost of goods sold in the Company's condensed consolidated statements of operations.  The net deferred gain of $ 459 on the cash flow hedge derivatives will be reclassified from other comprehensive income to the condensed consolidated statements of operations through December 2017.  Fair Value Measurements The Company’s assets and liabilities are measured at fair value on a recurring basis and are categorized using the three levels of the fair value hierarchy based on the reliability of the inputs used. Fair values estimated using Level 1 inputs consist of quoted prices in active markets for identical assets or liabilities that the Company has the ability to access at the measurement date. Fair values estimated using Level 2 inputs, other than quoted prices, are observable for the asset or liability, either directly or indirectly and include among other things, quoted prices for similar assets or liabilities in markets that are active or inactive as well as inputs other than quoted prices that are observable. For forward currency contracts , inputs include foreign currency exchange rates . Fair values estimated using Level 3 inputs consist of significant unobservable inputs.  Except for the earn-out liability discussed in Note 3, the Company did not have any financial assets or liabilities fair valued using Level 1 or Level 3 inputs at March 31, 2017 or December 31, 2016. The fair value of financial assets using Level 2 inputs related to forward currency contracts were $459 and $0 at March 31, 2017 and December 31, 2016, respectively. The fair value of financial liabilities using Level 2 inputs related to forward currency contracts were $0 and $31 at March 31, 2017 and December 31, 2016, respectively. The fair value of the earn-out liability related to Orlaco using Level 3 inputs was approximately $4,200 at March 31, 2017.  Except for the fair value of assets acquired and liabilities assumed related to the Orlaco acquisition discussed in Note 3, there were no non-recurring fair value measurements for the periods presented.

Earnings Per Share [Abstract]
Earnings Per Share	(9) Earnings Per Share Basic earnings per share was computed by divi ding net income by the weighted- average number of Common Shares outstand ing for each respective period. Diluted earnings per share was calculated by dividing net income by the weighted-average of all potentially dilutive Common Shares that were outstanding during the periods presented. As the Company adopted ASU 2016-09 on January 1, 2017 utilizing the prospective transition method, the weighted-average dilutive Common Shares calculation excludes the excess tax benefit from the treasury stock method for the three months ended March 31, 2017, while the calculation includes the excess tax benefits in the treasury stock method for the three months ended March 31, 2016.  Weighted-average Common Shares outstanding used in calculating basic and diluted earnings per share were as follows:      Three months ended March 31, 2017 2016  Basic weighted-average Common Shares outstanding 27,916,652 27,675,938  Effect of dilutive shares 663,545 479,835  Diluted weighted-average Common Shares outstanding 28,580,197 28,155,773  There were no performance- based rest ricted Common Shares outstanding at March 31, 2017 or 2016. There were 750,720 and 803,100 performance-based right to receive Common Shares outstanding at March 31, 2017 and 2016, respectively. These right to receive Common Shares are included in the computation of diluted earnings per share based on the number of Common Shares that would be issuable if the end of the quarter were the end of the contingency period .

Commitments and Contingencies [Abstract]
Commitments and Contingencies	(11 ) Commitments and Contingencies In the ordinary course of business, the Company is subject to a broad range of claims and legal proceedings that relate to contractual allegations, product liability, tax audits, patent infringement, employment-related matters and environmental matters. The Company establishes accruals for matters which it believes that losses are probable and can be reasonably estimable. Although it is not possible to predict with certainty the outcome of these matters, the Company is of the opinion that the ultimate resolution of these matters will not have a material adverse effect on its consolidated results of operations or financial position. As a result of environmental studies performed at the Company’s former facility located in Sarasota, Florida, the Company became aware of soil and groundwater contamination at the site. The Company engaged an environmental engineering consultant to assess the level of contamination and to develop a remediation and monitoring plan for the site. Soil remediation at the site was completed during the year ended December 31, 2010. As the remedial action plan has been approved by the Florida Department of Environmental Protection, groundwater remediation began in the fourth quarter of 2015. During the three months ended March 31, 2017 and 2016 , environmental remediation costs incurred were immaterial. At March 31, 2017 and December 31, 201 6 , the Company accrued a remaining undiscounted liability of $298 and $446 , respectively, related to future remediation costs. At March 31, 2017 and December 31, 201 6 , $232 and $370 , r espectively, were recorded as a component of accrued expenses and other current liabilities in the condensed consolidated balance sheets while the remaining amount was recorded as a component of other long-term liabilities. A majority of the costs associated with the recorded liability will be incurred at the start of the groundwater remediation, with the balance relating to monitoring costs to be incurred over multiple years. The recorded liability is based on assumptions in the remedial action plan. Although the Company sold the Sarasota facility and related property in December 2011, the liability to remediate the site contamination remains the responsibility of the Company. Due to the ongoing site remediation, the closing terms of the sale agreement included a requirement for the Company to maintain a $2,000 letter of credit for the benefit of the buyer.  The Company has a legal proceeding, Verde v. Stoneridge, Inc. et al ., currently pending in the United States District Court for the Eastern District of Texas, Cause No. 6:14-cv-00225- KNM. The plaintiff filed this putative class action against the Company and others on March 26, 2014. The plaintiff alleges that the Company was involved in the vertical chain of manufacture, distribution, and sale of a control device (“CD”) that was incorporated into a Dodge Ram truck purchased by Plaintiff in 2006. Plaintiff alleges that the Company breached express warranties and indemnification provisions by supplying a defective CD that was not capable of performing its intended function. The putative class consists of all Texas residents who own manual transmission Chrysler vehicles model years 1997–2007 equipped with the subject CD. Plaintiff seeks recovery of economic loss damages incurred by him and the putative class members associated with inspecting and replacing the allegedly defective CD, as well as attorneys’ fees and costs. Plaintiff filed a motion for class certification seeking to certify a class of Texas residents who own or lease certain automobiles sold by Chrysler from 1997–2007. Plaintiff alleges this putative class would include approximately 120,000 people. In the motion for class certification, the Plaintiff states that damages are no more than $1 per person. A hearing on the Plaintiff’s motion for class certification was held on November 16, 2015, and the United States District Court has not yet ruled on class certification. On April 8, 2016, the Magistrate Judge granted the Company’s motion for partial summary judgment dismissing the Plaintiff’s indemnification claim; that ruling was later adopted by the United States District Court (the “Court”) . On November 7, 2016, the Magistrate Judge issued a Report and Recommendation Concerning Class certification, in which she recommended denying Plaintiff’s motion for class certification. Plaintiff filed an objection to the Report and Recommendation concerning a motion for reconsideration concerning class certification. The Magistrate’s Report and Recommendation concerning class certification, and plaintiff’s objection and motion for reconsideration are currently before the Court pending a ruling from the District Judge. The Company believes the likelihood of loss is not probable or reasonably estimable, and therefore no liability has been recorded for these claims at March 31, 2017.  Royal v. Stoneridge, Inc. et al. is a legal proceeding currently pending in the United States District Court for the Western District of Oklahoma, Case No. 5:14-cv-01410-F. Plaintiffs filed this putative class action against the Company, Stoneridge Control Devices, Inc., and others on December 19, 2014. Plaintiffs allege that the Company was involved in the vertical chain of manufacture, distribution, and sale of a CD that was incorporated into Dodge Ram trucks purchased by Plaintiffs between 1999 and 2006. Plaintiffs allege that the Company and Stoneridge Control Devices, Inc. breached various express and implied warranties, including the implied warranty of merchantability. Plaintiffs also seek indemnity from the Company and Stoneridge Control Devices, Inc. The putative class consists of all owners of vehicles equipped with the subject CD, which includes various Dodge Ram trucks and other manual transmission vehicles manufactured from 1997–2007, which Plaintiffs allege is more than one million vehicles. Plaintiffs seek recovery of economic loss damages associated with inspecting and replacing the allegedly defective CD, diminished value of the subject CDs and the trucks in which they were installed, and attorneys’ fees and costs. The amount of compensatory or other damages sought by Plaintiffs and the putative class members is unknown. On January 12, 2016, the United States District Court granted in part the Company’s and Stoneridge Control Devices, Inc.’s motions to dismiss, and dismissed four of the Plaintiffs’ five claims against the Company and Stoneridge Control Devices, Inc. Plaintiffs filed a motion for reconsideration of the United States District Court’s ruling, which was denied. The Company filed a motion for judgment on the pleadings on March 3, 2017, which is currently before the Court. The Company is vigorously defending itself against the Plaintiffs’ allegations, and has and will continue to challenge the claims as well as class action certification. The Company believes the likelihood of loss is not probable or reasonably estimable, and therefore no liability has been recorded for these claims at March 31, 2017 .  On May 24, 2013, the State Revenue Services of São Paulo issued a tax deficiency notice against PST claiming that the vehicle tracking and monitoring services it provides should be classified as communication services, and therefore subject to the State Value Added Tax – ICMS. The State Revenue Services assessment imposed the 25.0% ICMS tax on all revenues of PST related to the vehicle tracking and monitoring services rendered during the period from January 2009 through December 2010. The Brazilian real (“R$”) and U.S. dollar equivalent (“$”) of the aggregate tax assessment is approximately R$92,500 ( $29,600 ) which is comprised of Value Added Tax – ICMS of R$13,200 ( $4,200 ) interest of R$11,400 ( $3,700 ) and penalties of R$67,900 ( $21,700 ) .   The Company believes that the vehicle tracking and monitoring services are non-communication services, as defined under Brazilian tax law, subject to the municipal ISS tax, not communication services subject to state ICMS tax as claimed by the State Revenue Services of São Paulo. PST has, and will continue to collect the municipal ISS tax on the vehicle tracking and monitoring services in compliance with Brazilian tax law and will defend its tax position. PST has received a legal opinion that the merits of the case are favorable to PST, determining among other things that the imposition on the subsidiary of the State ICMS by the State Revenue Services of São Paulo is not in accordance with the Brazilian tax code. Management believes, based on the legal opinion of the Company’s Brazilian legal counsel and the results of the Brazil Administrative Court's ruling in favor of another vehicle tracking and monitoring company related to the tax deficiency notice it received, the likelihood of loss is not probable although it may take years to resolve. As a result of the above, as of March 31, 2017 and December 31, 201 6 , no accrual has been recorded with respect to the tax assessment. An unfavorable judgment on this issue for the years assessed and for subsequent years could result in significant costs to PST and adversely affect its results of operations. There have been no significant changes to the facts and circumstances related to this notice for the three months ended March 31, 2017 . In addition, PST has civil, labor and other tax contingencies for which the likelihood of loss is deemed to be reasonably possible, but not probable, by the Company’s legal advisors in Brazil. As a result, no provision has been recorded with respect to these contingencies, which amounted to R$23,900 ( $7,700 ) and R$31,800 ( $9,800 ) at March 31, 2017 and December 31, 201 6 , respectively. An unfavorable outcome on these contingencies could result in significant cost to PST and adversely affect its results of operations.  Product Warranty and Recall Amounts accrued for product warranty and recall claims are established based on the Company's best estimate of the amounts necessary to settle existing and future claims on products sold as of the balance sheet dates. These accruals are based on several factors including past experience, production changes, industry developments and various other considerations including insurance coverage. The Company can provide no assurances that it will not experience material claims or that it will not incur significant costs to defend or settle such claims beyond the amounts accrued or beyond what the Company may recover from its suppliers. The current portion of product warranty and recall is included as a component of accrued expenses and other current liabilities in the condensed consolidated balance sheets. Product warranty and recall included $3,991 and $2,617 of a long-term liability at March 31, 2017 and December 31, 201 6 , respectively, which is included as a component of other long-term liabilities in the condensed consolidated balance sheets.  The following provides a reconciliation of changes in product warranty and recall liability:    Three months ended March 31 2017 2016  Product warranty and recall at beginning of period $ 9,344 $ 6,419  Accruals for products shipped during period 1,524 1,358  Assumed warranty liability related to Orlaco 1,462 -  Aggregate changes in pre-existing liabilities due to claim developments 1,614 (302)  Settlements made during the period (2,281) (348)  Product warranty and recall at end of period $ 11,663 $ 7,127

Income Taxes

Income Taxes [Abstract]
Income Taxes	(13 ) Income Taxes  The Company computes its consolidated income tax provision each quarter based on a projected annual effective tax rate, as required. The Company is required to reduce deferred tax assets by a valuation allowance if, based on all available evidence, it is considered more likely than not that some portion or all of the benefit of the deferred tax assets will not be realized in future periods. The Company also records the income tax impact of certain discrete, unusual or infrequently occurring items including changes in judgment about valuation allowances and effects of changes in tax laws or rates, in the interim period in which they occur.  When a company maintains a valuation allowance in a particular jurisdiction, no net income tax expense or (benefit) will typically be provided on income (loss) for that jurisdiction on an annual basis. Jurisdictions with projected income that maintain a valuation allowance typically will form part of the projected annual effective tax rate calculation discussed above. However, jurisdictions with a projected loss for the year that maintain a valuation allowance are excluded from the projected annual effective income tax rate calculation. Instead, the income tax for these jurisdictions is computed separately.  The actual year to date income tax expense (benefit) is the product of the most current projected annual effective income tax rate and the actual year to date pre-tax income (loss) adjusted for any discrete tax items. The income tax expense (benefit) for a particular quarter, except for the first quarter, is the difference between the year to date calculation of income tax expense (benefit) and the year to date calculation for the prior quarter.  Therefore, the actual effective income tax rate during a particular quarter can vary significantly based upon the jurisdictional mix and timing of actual earnings compared to projected annual earnings, permanent items, earnings for those jurisdictions that maintain a valuation allowance, tax associated with jurisdictions excluded from the projected annual effective income tax rate calculation and discrete items.     The Company recognized income tax expense of $ 4,571 and $845 for federal, state and foreign income taxes for the three months ended March 31, 2017 and 2016, respectively. The increase in income tax expense for the three months ended March 31, 2017 compared to the same period for 2016 was primarily related to the release of the U.S. federal, certain state and foreign valuation allowances in the fourth quarter of 2016 that were previously recorded against certain deferred tax assets . T he effective tax rate increased to 33.3% in the first quarter of 2017 from 12.2% in the first quarter of 2016 primarily due the continued strong performance of the U.S. operations, which due to a full valuation allowance positively impacted the effective tax rate in 2016.

Segment Reporting [Abstract]
Segment Reporting	(1 4 ) Segment Reporting Operating segments are defined as components of an enterprise that are evaluated regularly by the Company's chief operating decision maker in deciding how to allocate resources and in assessing performance. The Company's chief operating decision maker is the chief executive officer. The Company has three reportable segments , Control Devic es, Electronics, and PST , which also represent its operating segments. The Control Devices reportable segment produces sensors, switches, valves and actuators. The Electronics reportable segment produces electronic instrument clusters, electronic control units and driver information systems and includes the newly acquired Orlaco business which designs and manufactures a variety of camera-based vision systems, monitors and related products. The PST reportable segment designs and manufactures electronic vehicle security alarms, convenience accessories, vehicle tracking devices and monitoring services and in-vehicle audio and video devices.  The accounting policies of the Company's reportable segments are the same as those described in Note 2, “Summary of Significant Accounting Policies” of the Company's 2016 Form 10-K. The Company's management evaluates the performance of its reportable segments based primarily on revenues from external customers and operating income . Inter-segment sales are accounted for on terms similar to those to third parties and are eliminated upon consolidation.  The financial information presented below is for our three reportable operating segments and includes adjustments for unallocated corporate costs and intercompany eliminations, where applicable.
