Feds Investigate GM's 6.2-Liter V8s That Keep Failing Despite Fixes: TDS

U.S. regulators have widened a probe into General Motors’ L87 small-block V8 engines after continued complaints from owners despite prior recalls. The National Highway Traffic Safety Administration (NHTSA) is now using new engineering analysis to evaluate whether GM’s fixes are working and to assess how effectively they reduce engine-failure risk. The investigation covers nearly a million trucks and SUVs that use the engine, spanning Chevrolet Silverado, Cadillac Escalade and GMC Yukon models from 2021 through 2026. In other automotive news roundup items, Stellantis recalled certain 2021–2023 Dodge Durangos due to rear-spoiler misalignment, and China began a massive recall involving emergency door releases on electronic-handle vehicles. The bulletin also notes updates on Lamborghini, Uber, Tesla’s solar roof discontinuation, and upcoming weekend motorsport schedules.
