GM Faces Potential Class Action Over Alleged Engine Defects in Multiple Vehicle Models

Kantrowitz, Goldhamer & Graifman, P.C. is pursuing a potential class action lawsuit against General Motors (GM) after receiving reports of critical engine failures in several vehicle models. The investigation centers on the 6.2L V9 L87 engines installed in Chevrolet and GMC vehicles between 2019 and 2024.

The National Highway Traffic Safety Administration (NHTSA) has documented consumer complaints alleging sudden power loss due to engine bearing failures. These mechanical issues could cause engines to seize or experience connecting rod breaches, potentially resulting in unexpected vehicle power loss while driving.

Affected vehicle models include Chevrolet Silverado 1500, Chevrolet Tahoe, Chevrolet Suburban, GMC Sierra 1500, GMC Yukon, GMC Yukon XL, and Cadillac Escalade series from 2021-2024. Despite multiple consumer reports, GM has not yet issued a formal recall for these vehicles.

The potential engine defects represent significant safety concerns, as unexpected power loss could substantially increase crash risks for vehicle occupants and other road users. The law firm is evaluating a class action lawsuit that could provide compensation for affected vehicle owners, including potential damages for repair costs and diminished vehicle value.

This investigation highlights the critical importance of automotive manufacturers addressing potential mechanical vulnerabilities that could compromise vehicle safety and consumer trust.
