GM Faces Potential Warranty Issue Over L87 Engine Failure

Overview:

The National Highway Traffic Safety Administration (NHTSA) has initiated a preliminary investigation into potential engine failures affecting over 877,000 GM SUVs and trucks equipped with the L87 6.2L V8 engine.

Affected Vehicles:

* 2019-2024 Chevrolet Silverado 1500 and GMC Sierra 1500 pickups
* 2021-2024 Chevrolet Tahoe, Chevrolet Suburban, GMC Yukon, and Cadillac Escalade SUVs

Issue:

The NHTSA has received complaints and field reports alleging that the L87 engine is experiencing a potential bearing failure, which can lead to engine seizure or damage to the engine block. These failures occur without warning and may result in loss of power, increasing the risk of a crash.

Investigation:

The NHTSA's Office of Defects Investigation (ODI) will assess the scope and severity of the potential issue, including the root cause of the bearing failures.

GM's Response:

A GM spokesperson stated that the company is cooperating with NHTSA's investigation and prioritizing the safety and satisfaction of its customers.

Potential Recall:

An ODI investigation can lead to a voluntary recall, requiring the manufacturer to fix the defect responsible for the safety issue. In this case, GM may need to address the potential bearing failures on approximately 878,000 vehicles, potentially resulting in significant repair or replacement costs.

Financial Impact:

GM has previously spent $700 million on warranty claims related to safety recalls. If a recall is required for the L87 engine issue, it could further impact the company's financial results.

Additional Information:

* The issue appears to involve a failed bearing holding the engine crankshaft and connecting rod in place.
* GM has previously addressed a similar issue with "oversized lifter bores" in MY 2023 vehicles through a customer satisfaction program.
