The owner of a Chevy Silverado in Ohio has filed a lawsuit against General Motors that claims her vehicle has suffered excessive oil consumption–though GM doesn’t believe there is enough evidence to warrant the suit, according to GM Authority.
The class action lawsuit was first filed in December 2020 on behalf of plaintiff Lisa Mae Jennings, who alleges that her vehicle needed an oil pressure switch, an AFM lifter, and a camshaft to be replaced, as well as two quarts of oil added to the truck in between 6,521-mile oil changes.
Other similar lawsuits have been filed, alleging issues with excessive oil consumption and defective piston rings in Generation IV 5.3L Vortec V8 engines. One similar suit in Alabama was dismissed due to reaching the statute of limitations, while one in Georgia and another in Virginia both ended with a verdict of insufficient evidence.
Of the lawsuits filed, it’s been claimed that vehicles affected by the problem include the 2010-2014 Chevrolet Silverado; 2010-2014 Chevrolet Suburban; 2010-2014 Chevrolet Tahoe; 2010-2014 Chevrolet Avalanche; 2010-2014 GMC Sierra; 2010-2014 GMC Yukon; and the 2010-2014 GMC Yukon XL.
Similarly to the results of previous suits, GM said that there is inadequate evidence to claim that Jenning’s truck contains any defects and that her suit should be dismissed.
“The truck has not needed any other repairs, and plaintiff has never had an oil consumption test performed,” countered the automaker. “There is no evidence that any of the repairs to her truck had anything to do with excess oil consumption or a piston ring defect.”
