GM has recalled multiple vehicles associated with 6.2 engine defects. 

Problem and Remedy

Chronology and History : On January 16, 2025, GM opened a product investigation following notification from NHTSA of its investigation into alleged engine failures in GM vehicles equipped with the L87 V8 engine. GM closed three prior investigations into this condition in February 2022, June 2023, and July 2024 based on the available safety field information.  

Findings about Engine Failure 

GM's updated field data analysis identified a build period from March 1, 2021, to May 31, 2024, with an increased rate of potentially related engine failure claims. GM's investigator reviewed findings from teardowns of field engines and data from a study of new, unused crankshafts. Supplier manufacturing and quality issues were identified at intermittent periods within the suspect build period, including (1) rod-bearing damage from sediment on connecting rods and crankshaft-oil galleries; and (2) out of specification crankshaft dimensions and surface finish. These issues can cause or contribute to bearing damage that can lead to loss of propulsion and engine failure.   GM's investigation identified 28,102 field complaints or incidents in the US potentially related to failure of the L87 engine due to crankshaft, connecting rod, or engine bearing failure, of which 14,332 involved allegations of loss of propulsion.  These field complaints were received between April 29, 2021, and February 3, 2025. GM identified 12 potentially related alleged crashes and 12 potentially related alleged injuries in the U.S.; all specifically alleged injuries were minor or non-physical, and most were not crash related.  

Repair Coverage

Pursuant to 577.11, GM will provide reimbursement to owners for repairs according to the plan submitted under USG 5916 on May 12, 2023. This should include c connecting rods and crankshafts in repaired or replaced engines.

Multiple lawsuits were consolidated in the U.S. District Court for the Eastern District of Michigan (lead case: Powell et al. v. General Motors LLC, 4:25-cv-10479). They allege GM knew about manufacturing defects in L87 connecting rod/crankshaft bearings leading to catastrophic engine failure. A ~389-page consolidated complaint was filed around February/March 2026.
