In the wake of this April’s
major recall of 598,000 full-size trucks and SUVs due to issues with their 6.2-liter V-8 engines, General Motors is now facing a new class action lawsuit. The case was filed on Monday, May 19 by Seattle’s
Hagens Berman law firm in the U.S. District Court for the Eastern District of Michigan. The plaintiffs allege that GM knowing sold vehicles containing a definitive engine, fully aware of the safety hazards that decision presented.
The lawsuit, featuring plaintiffs from Washington and California, details familiar issues with the L87 engine, specifically in vehicles manufactured for model years 2021–2024. As outlined in that April recall, the engines may feature sediment on the connecting rods or in the oil galleries for the crankshaft, which can lead to rod-bearing damage. GM has also acknowledged some engines may feature a crankshaft that is out of production spec. Any of these issues can result in a catastrophic engine failure.
The engines were installed in popular models like the Chevrolet Silverado 1500,
Tahoe and
Suburban, GMC Sierra 1500,
Yukon and Yukon XL, as well as the
Cadillac Escalade and Escalade ESV.
Beyond the safety issue, the plaintiffs allege that this situation is causing financial harm due to decreased vehicle values. They further claim that replacing the defective powertrains with new L87 V8s doesn’t properly address the bearing issue, leaving owners at risk of further issues.
While that sentiment is understandable, GM maintains that the faults have been remedied for model year 2025. The automaker’s internal investigation was able to locate a specific manufacturing defect that reportedly only impacted engines built between March 1st, 2021, and May 31st, 2024. That said, the lawsuit specifically includes model year 2019+ Silverado 1500 and Sierra 1500s in its list of impacted vehicles.
