Commitments and Contingencies Disclosure [Abstract]
Commitments And Contingencies	COMMITMENTS AND CONTINGENCIES Ordinary Business Litigation Aptiv is from time to time subject to various legal actions and claims incidental to its business, including those arising out of alleged defects, alleged breaches of contracts, product warranties, intellectual property matters, and employment-related matters. It is the opinion of Aptiv that the outcome of such matters will not have a material adverse impact on the consolidated financial position, results of operations, or cash flows of Aptiv. With respect to warranty matters, although Aptiv cannot ensure that the future costs of warranty claims by customers will not be material, Aptiv believes its established reserves are adequate to cover potential warranty settlements. Matters Related to Global Supply Chain Disruptions Due to various factors that are beyond our control, there are currently global supply chain disruptions, including a worldwide semiconductor supply shortage. The semiconductor supply shortage, due in part to increased demand across multiple industries, is impacting production in automotive and other industries. We anticipate these supply chain disruptions will persist throughout 2022. We, along with most automotive component manufacturers that use semiconductors, have been unable to fully meet the vehicle production demands of OEMs because of events which are outside our control, including but not limited to, the COVID-19 pandemic, the global semiconductor shortage, fires in our suppliers’ facilities, unprecedented weather events in the southwestern United States, and other extraordinary events. Although we are working closely with suppliers and customers to minimize any potential adverse impacts of these events, some of our customers have indicated that they expect us to bear at least some responsibility for their lost production and other costs. While no assurances can be made as to the ultimate outcome of these customer expectations or any other future claims, we do not currently believe a loss is probable, and accordingly, no reserve has been made as of December 31, 2021. We will continue to actively monitor all direct and indirect potential impacts of these supply chain disruptions, and will seek to aggressively mitigate and minimize their impact on our business. Brazil Matters Aptiv conducts business operations in Brazil that are subject to the Brazilian federal labor, social security, environmental, health and safety, tax and customs laws, as well as a variety of state and local laws. While Aptiv believes it complies with such laws, they are complex, subject to varying interpretations, and the Company is often engaged in litigation with government agencies regarding the application of these laws to particular circumstances. As of December 31, 2021, the majority of claims asserted against Aptiv in Brazil relate to such litigation. The remaining claims in Brazil relate to commercial and labor litigation with private parties. As of December 31, 2021, claims totaling approximately $95 million (using December 31, 2021 foreign currency rates) have been asserted against Aptiv in Brazil. As of December 31, 2021, the Company maintains accruals for these asserted claims of $20 million (using December 31, 2021 foreign currency rates). The amounts accrued represent claims that are deemed probable of loss and are reasonably estimable based on the Company’s analyses and assessment of the asserted claims and prior experience with similar matters. While the Company believes its accruals are adequate, the final amounts required to resolve these matters could differ materially from the Company’s recorded estimates and Aptiv’s results of operations could be materially affected. The Company estimates the reasonably possible loss in excess of the amounts accrued related to these claims to be zero to $75 million. Environmental Matters Aptiv is subject to the requirements of U.S. federal, state, local and non-U.S. environmental, health and safety laws and regulations. As of December 31, 2021 and 2020, the undiscounted reserve for environmental investigation and remediation recorded in other long-term liabilities was approximately $4 million and $4 million, respectively. Aptiv cannot ensure that environmental requirements will not change or become more stringent over time or that its eventual environmental remediation costs and liabilities will not exceed the amount of its current reserves. In the event that such liabilities were to significantly exceed the amounts recorded, Aptiv’s results of operations could be materially affected. At December 31, 2021 the difference between the recorded liabilities and the reasonably possible range of potential loss was not material.
