General Motors is under fire after federal regulators flagged its 6.2\u2011liter V8 for sudden seizures that could stall popular Chevrolet, Cadillac, and GMC models built since 2021.<\/p>\n\n\n\n
General Motors, one of Detroit\u2019s \u201cbig three,\u201d must recall roughly 600,000 large SUVs and pickups in the United States\u2014721,000 worldwide\u2014after reports that the L87 V8 can lock up without warning. The same defect sits at the heart of a newly filed class\u2011action lawsuit, Case\u202fNo.\u202f2:25\u2011cv\u201110479, which accuses GM of selling engines it allegedly knew were risky.<\/p>\n\n\n\n
Who is most affected? Owners and lessees of 2021\u20112024 Chevrolet Tahoe, Suburban, Silverado\u202f1500; GMC Yukon and Sierra\u202f1500; and the Cadillac Escalade. Dealers must replace or repair the engines free of charge, but the clock is ticking.<\/p>\n\n\n\n
The National Highway Traffic Safety Administration\u2019s Recall\u202f25V\u2011274 says GM was alerted to random seizing nearly three years ago. Yet production continued, and the company only issued a recall after complaints piled up. <\/p>\n\n\n\n
That delay fuels the lawsuit, which claims drivers had \u201cno advance warning\u201d before losing power\u2014an alarming prospect on a busy interstate, don\u2019t you think?
