Hagens Berman filed a nationwide class action for GM owners alleging a dangerous bearing defect in vehicles with the L87 6.2‑liter V‑8 engine that can cause sudden, total engine failure. Owners report no warning before failures, which have occurred in vehicles with as few as 1,200 miles. The defect renders affected vehicles unsafe and, even after the proposed recall remedy, significantly reduces their value; plaintiffs contend that had GM disclosed the defect, consumers would not have purchased the vehicles or would have paid substantially less.
