Either defect can result in complete engine failure.The lawsuit cites internal GM documents that allegedly demonstrate the automaker’s awareness of the issue as far back as March 2023. A bulletin published to GM’s Techlink platform—a communication channel for dealer service personnel—described a “no crank” condition in certain models and warned that sounds such as knocking or thumping could point to crankshaft bearing problems.gm 6 2 lawsuitThe 6.2L V8, designated L87, is used in a wide range of full-size GM vehicles, including the Cadillac Escalade, Chevrolet Silverado 1500, Suburban, Tahoe, and the GMC Sierra 1500, Yukon, and Yukon XL. Affected model years span from 2021 through 2024.While GM has issued a recall, the legal complaint argues the automaker didn't act until it was too late for many owners who were forced to experience costly breakdowns and subsequent repairs. The suit seeks damages and a jury trial.With growing scrutiny on its quality control processes, GM must also face flagging consumer trust in its most profitable lineup—trucks and full-size SUVs remain a core foundation of the company’s bottom line—you know, the things paying for the development of all those EVs people aren't really buying.
