Class Action Lawsuit Filed Over GM 6.2L V8 L87 Engine

A class action lawsuit against General Motors claims that defective bearings in the L87 V8 engine lead to engine failures.

The lawsuit states that the following vehicles are equipped with faulty L87 engines:

The General Motors L87 engine lawsuit was filed roughly four weeks after the National Highway Traffic Safety Administration launched an investigation into issues with the L87 engine.

Of the 877,710 GM vehicles equipped with L87 engines, the NHTSA received 39 complaints along with several field reports.

The engine lawsuit was filed by Illinois resident James S. Powell II, who bought a new 2023 GMC Yukon Denali in October 2022. His vehicle was equipped with an L87 engine, and in October 2024, he brought his GMC Yukon to a dealership after the check engine light illuminated.

The class action claims that Powell’s GM L87 engine contained metal in the oil and that the engine block was damaged due to a faulty connecting rod bearing. The plaintiff is represented by the law firms Coulson P.C., Goldenberg Heller & Antognoli, P.C., Byron Carlson Petri & Kalb, LLC, and Arias Sanguinetti Wang & Team, LLP.

Although his L87 engine was replaced at no cost, Powell filed the class action seeking over $5 million, alleging that the replacement engine is just as defective as the original.

General Motors is accused of being aware of the L87 engine issues for ‘several years’ but failing to notify owners and lessees of Cadillac, Chevrolet, and GMC vehicles about the potential for engine failure.
