Engine Oil Issue Costs GM $102.6M in Lawsuit

Oct. 21, 2022

The class action lawsuit alleges GM knew about the defect.

Oct. 21, 2022— A California jury has found General Motors negligent in a class action lawsuit verdict. As reported by Jalopnik, the automaker will be on the hook for $102.6 million over accusations it hid an engine defect that led to excessive oil consumption. 

The engine defect in question—found in GMs 5.3-liter V8s sold in California, North Carolina and Idaho between 2011 and 2014—was the result of a faulty piston ring design that allowed oil to leak out into the engine. 

Despite the hefty settlement, the 38,000 owners of the vehicles will each walk away with $2,700.
