General Motors agreed to a $150 million class action lawsuit settlement to resolve claims that certain Chevrolet and GMC vehicles are equipped with defective engines that consume excessive oil.
The GM settlement benefits current owners or lessees of 2011-2014 Chevrolet Avalanche, Silverado, Suburban, Tahoe, GMC Sierra, Yukon and Yukon XL vehicles equipped with LC9 engines who live in California, Idaho or North Carolina.
According to the class action lawsuit, certain Chevrolet and GMC vehicles are equipped with defective LC9 engines that consume excessive amounts of oil. Plaintiffs in the case say that GM knew about the defect but failed to disclose it to consumers.
