Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Litigation-Related Liability and Tax Administrative Matters In the normal course of our business, we are named from time to time as a defendant in various legal actions, including arbitrations, class actions and other litigation. We identify below the material individual proceedings and investigations where we believe a material loss is reasonably possible or probable. We accrue for matters when we believe that losses are probable and can be reasonably estimated. At June 30, 2023 and December 31, 2022, we had accruals of $1.0 billion and $1.1 billion in Accrued liabilities and Other liabilities. In many matters, it is inherently difficult to determine whether a loss is probable or reasonably possible or to estimate the size or range of the possible loss. Some matters may involve compensatory, punitive or other treble damage claims, environmental remediation programs or sanctions that, if granted, could require us to pay damages or make other expenditures in amounts that cannot be reasonably estimated. Accordingly, while we believe that appropriate accruals have been established for losses that are probable and can be reasonably estimated, it is possible that adverse outcomes from such proceedings could exceed the amounts accrued by an amount that could be material to our results of operations or cash flows in any particular reporting period. GM Korea Subcontract Workers Litigation GM Korea Company (GM Korea) is party to litigation with current and former subcontract workers over allegations that they are entitled to the same wages and benefits provided to full-time employees, and to be hired as full-time employees. In May 2018 and September 2020, the Korean labor authorities issued adverse administrative orders finding that GM Korea must hire certain current subcontract workers as full-time employees. GM Korea appealed the May 2018 and September 2020 orders. Since June 2020, the Seoul High Court (an intermediate-level appellate court) ruled against GM Korea in eight subcontract worker cases. Although GM Korea has appealed these decisions to the Supreme Court of the Republic of Korea, GM Korea has since hired certain of its subcontract workers as full-time employees. At June 30, 2023, our accrual covering certain asserted claims and claims that we believe are probable of assertion and for which liability is probable was approximately $194 million. We estimate the reasonably possible loss in excess of amounts accrued for other current subcontract workers who may assert similar claims to be approximately $94 million at June 30, 2023. We are currently unable to estimate any reasonably possible material loss or range of loss that may result from additional claims that may be asserted by former subcontract workers. Other Litigation-Related Liability and Tax Administrative Matters Various other legal actions, including class actions, governmental investigations, claims and proceedings are pending against us or our related companies or joint ventures, including, but not limited to, matters arising out of alleged product defects; employment-related matters; product and workplace safety, vehicle emissions and fuel economy regulations; product warranties; financial services; dealer, supplier and other contractual relationships; government regulations relating to competition issues; tax-related matters not subject to the provision of Accounting Standards Codification 740, "Income Taxes" (indirect tax-related matters); product design, manufacture and performance; consumer protection laws; and environmental protection laws, including laws regulating air emissions, water discharges, waste management and environmental remediation from stationary sources. We also from time to time receive subpoenas and other inquiries or requests for information from agencies or other representatives of U.S. federal, state and foreign governments on a variety of issues. There are several putative class actions pending against GM in federal courts in the U.S. and in the Provincial Courts in Canada alleging that various vehicles sold, including model year 2011-2016 Duramax Diesel Chevrolet Silverado and GMC Sierra vehicles, violate federal, state and foreign emission standards. In July 2023, the putative class actions pending in the U.S. were dismissed with prejudice and judgement entered in favor of GM, and plaintiffs appealed the dismissal. We are currently unable to estimate any reasonably possible material loss or range of loss that may result from these actions. GM has also faced a series of additional lawsuits in the U.S. based on these allegations, including a shareholder demand lawsuit that remains pending. There are several putative class actions and two certified class actions pending against GM in federal courts in the U.S. alleging that various 2011-2014 model year vehicles are defective because they excessively consume oil. While many of these proceedings have been dismissed or have been settled for insignificant amounts, several remain outstanding, and in October 2022, we received an adverse jury verdict in the certified class action proceeding involving three states. We do not believe that the verdict is supported by the evidence and plan to appeal, if necessary. We are currently unable to estimate any reasonably possible material loss or range of loss that may result from the putative class action proceedings and have previously accrued an immaterial amount related to one of the certified class action proceedings. There is one putative class action and one certified class action pending against GM in federal court in the U.S. alleging that various 2015-2022 model year vehicles are defective because they are equipped with faulty 8-speed transmissions. In March 2023, the judge overseeing the class action concerning 2015-2019 model year vehicles certified 26 state subclasses. The putative class action concerning 2020-2022 model year vehicles is pending in front of a different judge that has not yet addressed class certification. We have similar cases pending in Canada concerning these vehicles. We are currently unable to estimate any reasonably possible material loss or range of loss that may result from these proceedings. There is a class action pending against GM in federal court in the U.S., and a putative class action in provincial court in Canada, alleging that 2011-2016 model year Duramax Diesel Chevrolet Silverado and GMC Sierra vehicles are equipped with defective fuel pumps that are prone to failure. In March 2023, the federal court certified seven state subclasses. We are currently unable to estimate any reasonably possible material loss or range of loss that may result from these proceedings. Beyond the class action litigations disclosed, we have several other class action litigations pending at any given time. Historically, relatively few classes have been certified in these types of cases. Therefore, we will generally only disclose specific class actions if a class is certified and we believe there is a reasonably possible material exposure to the Company. We are currently in discussions with the Environmental Protection Agency (EPA) regarding potential adjustments to our balance of greenhouse gas (GHG) credits. Based on progress made in these discussions, in the three months ended June 30, 2023, we accrued $150 million. Through June 30, 2023, the total costs expensed in connection with these matters were $311 million. We are currently unable to provide an estimate of the loss in excess of amounts incurred, but such loss may be material. Indirect tax-related matters are being evaluated globally pertaining to value added taxes, customs, duties, sales, property taxes and other non-income tax-related tax exposures. Certain administrative proceedings are indirect tax-related and may require that we deposit funds in escrow or provide an alternative form of security. For indirect tax-related matters, we estimate our reasonably possible loss in excess of amounts accrued to be up to approximately $1.6 billion at June 30, 2023. Takata Matters In November 2020, the National Highway Traffic Safety Administration (NHTSA) directed that we replace the Takata Corporation (Takata) airbag inflators in our GMT900 vehicles, which are full-size pickup trucks and sport utility vehicles (SUVs), and we did not contest NHTSA's decision. While we have already begun the process of executing the recall, given the number of vehicles in this population, the recall will take several years to be completed. Accordingly, in the year ended December 31, 2020, we recorded a warranty accrual of $1.1 billion for the expected costs of complying with the recall remedy, and we believe the currently accrued amount remains reasonable. GM has recalled certain vehicles sold outside of the U.S. to replace Takata inflators in those vehicles. There are significant differences in vehicle and inflator design between the relevant vehicles sold internationally and those sold in the U.S. We continue to gather and analyze evidence about these inflators and to share our findings with regulators. Any additional recalls relating to these inflators could be material to our results of operations and cash flows. There are several putative class actions that have been filed against GM, including in the federal courts in the U.S., in the Provincial Courts in Canada, and in Mexico, arising out of allegations that airbag inflators manufactured by Takata are defective. In March 2023, a federal court overseeing a putative class action against GM issued a final judgment in favor of GM on all claims in eight states at issue in that proceeding; claims relating to other states remain pending. At this stage of these proceedings, we are unable to provide an estimate of the amounts or range of reasonably possible material loss. ARC Matters In May 2023, we initiated a voluntary recall covering nearly one million 2014-2017 model year Buick Enclave, Chevrolet Traverse, and GMC Acadia SUVs equipped with driver front airbag inflators manufactured by ARC Automotive, Inc. (ARC), and accrued an immaterial amount for the expected costs of the recall. As part of its ongoing investigation into ARC airbag inflators, NHTSA has issued a recall request letter to ARC, in which the agency (a) tentatively concluded that a defect related to motor vehicle safety exists in 67 million frontal driver and passenger air bag inflators manufactured by ARC and supplied to a number of automakers, including GM, and (b) demanded that ARC issue a recall notice for these inflators. ARC has disputed the recall request, asserting that no identified defect trend exists in the inflators and that any problems are related to isolated manufacturing issues. Depending on the outcome of the dispute between NHTSA and ARC, and the possibility of additional recalls, the cost of which may not be fully recoverable, it is reasonably possible that the costs associated with these matters in excess of amounts accrued could be material, but we are unable to provide an estimate of the amounts or range of reasonably possible material loss at this time. There are several putative class actions that have been filed against GM, including in the U.S., Canada, and Israel, arising out of allegations that airbag inflators manufactured by ARC are defective. At this stage of these proceedings, we are unable to provide an estimate of the amounts or range of reasonably possible material loss. Chevrolet Bolt Recall In July 2021, we initiated a voluntary recall for certain 2017-2019 model year Chevrolet Bolt EVs due to the risk that two manufacturing defects present in the same battery cell could cause a high voltage battery fire in certain of these vehicles. Accordingly, in the three months ended June 30, 2021, we recorded a warranty accrual of $812 million. After further investigation into the manufacturing processes at our battery supplier, LG Energy Solution (LGES), and disassembling battery packs, we determined that the risk of battery cell defects was not confined to the initial recall population. As a result, in August 2021, we expanded the recall to include all 2017-2022 model year Chevrolet Bolt EV and Electric Utility Vehicles (EUVs) and recorded an additional warranty accrual of $1.2 billion in the three months ended September 30, 2021. In October 2021, we reached an agreement with LG Electronics, Inc. (LGE), under which LGE agreed to reimburse GM for costs and expenses associated with the recall. As a result, in the three months ended September 30, 2021, we recognized a receivable of $1.9 billion, which substantially offset the warranty charges we recognized in connection with the recall. In the three months ended June 30, 2023, we recorded a charge of $792 million to reflect a settlement agreement with LGES and LGE (collectively, LG) whereby the parties agreed to reduce the amount of recall costs and expenses for which LG would reimburse GM. The commercial negotiations with LG also resolved other commercial matters associated with our Ultium Cells Holdings LLC joint venture with LGES. These charges reflect our current best estimate for the cost of the recall remedy, which includes non-traditional recall remedies provided by GM to enhance customer satisfaction. The actual costs of the recall could be materially higher or lower. For 2017-2019 model year vehicles, the recall remedy will be to replace the high voltage battery modules in these vehicles with new modules. For approximately half of the 2020-2022 model year vehicles, recently developed battery diagnostic software will be the recall remedy, with the remainder receiving new high voltage battery modules. In addition, putative class actions have been filed against GM in federal courts in the U.S. and in the Provincial Courts in Canada alleging that the batteries contained in the Bolt EVs and EUVs included in the recall population are defective. GM has reached an agreement in principle to settle the U.S. class actions for an immaterial amount. Opel/Vauxhall Sale In 2017, we sold the Opel and Vauxhall businesses and certain other assets in Europe (the Opel/Vauxhall Business) to PSA Group, now Stellantis N.V. (Stellantis), under a Master Agreement (the Agreement). We also sold the European financing subsidiaries and branches to Banque PSA Finance S.A. and BNP Paribas Personal Finance S.A. Although the sale reduced our new vehicle presence in Europe, we may still be impacted by actions taken by regulators related to vehicles sold before the sale. General Motors Holdings LLC agreed, on behalf of our wholly owned subsidiary (the Seller), to indemnify Stellantis for certain losses resulting from any inaccuracy of the representations and warranties or breaches of our covenants included in the Agreement and for certain other liabilities, including costs related to certain emissions claims, product liabilities and recalls. We are unable to estimate any reasonably possible material loss or range of loss that may result from these actions either directly or through an indemnification claim from Stellantis. Certain of these indemnification obligations are subject to time limitations, thresholds and/or caps as to the amount of required payments. Currently, various consumer lawsuits have been filed against the Seller and Stellantis in Germany, the United Kingdom and the Netherlands alleging that Opel and Vauxhall vehicles sold by the Seller violated applicable emissions standards. In addition, we indemnified Stellantis for an immaterial amount for certain recalls that Stellantis has conducted or will conduct, including recalls in certain geographic locations that Stellantis intends to conduct related to Takata inflators in legacy Opel vehicles. We may in the future be required to further indemnify Stellantis relating to its Takata recalls, but we believe such further indemnification to be remote at this time. Product Liability We recorded liabilities of $590 million and $561 million in Accrued liabilities and Other liabilities at June 30, 2023 and December 31, 2022 for the expected cost of all known product liability claims, plus an estimate of the expected cost for product liability claims that have already been incurred and are expected to be filed in the future for which we are self-insured. It is reasonably possible that our accruals for product liability claims may increase in future periods in material amounts, although we cannot estimate a reasonable range of incremental loss based on currently available information. We believe that any judgment against us involving our products for actual damages will be adequately covered by our recorded accruals and, where applicable, excess liability insurance coverage. Guarantees We enter into indemnification agreements for liability claims involving products manufactured primarily by certain joint ventures. These guarantees terminate in years ranging from 2023 to 2028, or upon the occurrence of specific events or are ongoing. We believe that the related potential costs incurred are adequately covered by our recorded accruals, which are insignificant. The maximum future undiscounted payments mainly based on royalties received associated with vehicles sold to date were $3.4 billion and $3.1 billion for these guarantees at June 30, 2023 and December 31, 2022, the majority of which relates to the indemnification agreements. We provide payment guarantees on commercial loans outstanding with third parties such as dealers. In some instances, certain assets of the party or our payables to the party whose debt or performance we have guaranteed may offset, to some degree, the amount of any potential future payments. We are also exposed to residual value guarantees associated with certain sales to rental car companies. We periodically enter into agreements that incorporate indemnification provisions in the normal course of business. It is not possible to estimate our maximum exposure under these indemnifications or guarantees due to the conditional nature of these obligations. Insignificant amounts have been recorded for such obligations as the majority of them are not probable or estimable at this time and the fair value of the guarantees at issuance was insignificant. Refer to the Opel/Vauxhall Sale section of this note for additional information on our indemnification obligations to Stellantis under the Agreement. Supplier Finance Programs Third-party finance providers offer certain suppliers the option for payment in advance of their invoice due date through financing programs that we established. We retain our obligation to the participating suppliers, and we make payments directly to the third-party finance providers on the original invoice due date pursuant to the original invoice terms. There are no assets pledged as security or other forms of guarantees provided for committed payments. Our outstanding eligible balances under our supplier finance programs are $1.1 billion and $852 million at June 30, 2023 and December 31, 2022, which are recorded in Accounts payable (principally trade).
