Engine Failure Investigation: NHTSA Probes GM SUVs and Trucks
Summary:
The National Highway Traffic Safety Administration (NHTSA) has initiated a preliminary investigation into potential engine failures affecting approximately 877,710 GM SUVs and trucks. The investigation focuses on vehicles equipped with the L87 engine, a 6.2L V8 widely used in GM models.
Affected Vehicles:
* 2019-2024 Chevrolet Silverado 1500 and GMC Sierra 1500 pickups
* 2021-2024 Chevrolet Tahoe, Chevrolet Suburban, GMC Yukon, and Cadillac Escalade SUVs
Potential Issue:
The NHTSA received complaints and field reports alleging engine failure in L87-equipped vehicles. The reports indicate a potential failure of a bearing that connects the crankshaft and connecting rod. This issue can lead to engine seizure or breach of the engine block, resulting in a loss of power and increased crash risk.
GM Response:
GM has cooperated with the NHTSA investigation and emphasized its commitment to customer safety. A spokesperson stated that the company is monitoring the situation and will take appropriate action.
Potential Recall:
If the investigation reveals a significant safety issue, a voluntary recall may be necessary. GM would then be required to repair the affected vehicles by replacing connecting rod bearings or, if necessary, entire engines.
Financial Implications:
A recall involving approximately 878,000 vehicles could result in substantial costs for GM. The company's warranty claims in the third quarter of 2022 reached $700 million, and the investigation's findings may further impact its financial performance.
