GM has called for the dismissal of a class action lawsuit filed against the automaker in Ohio that alleges multiple Chevy and GMC vehicle models have a defect causing them to consumer an “excessive” amount of oil, citing lack of evidence to back up the claims.
Per a report by Car Complaints, The General also points out the plaintiff is still driving the 2013 Chevy Silverado she claims is defective, and has put over 100,000 miles on the odometer without any repairs related to the alleged issue being carried out.
Plaintiff Lisa Mae Jennings claims that her Chevy Silverado truck needed an oil pressure switch replaced, which she paid for because it was past warranty. Other reported repairs include replacement of an AFM lifter and a camshaft at various other times. She also asserts her husband has needed to add two quarts of oil to the truck between 6,521-mile oil changes.
Her suit is one of several related to allegedly excessive oil consumption and defective piston rings in the Generation IV 5.3L Vortec V8 engine. Jennings’ suit was filed in the U.S. District Court for the Northern District of Ohio during December 2020. The following vehicles are said to have the issue:
- 2010-2014 Chevrolet Silverado
- 2010-2014 Chevrolet Suburban
- 2010-2014 Chevrolet Tahoe
- 2010-2014 Chevrolet Avalanche
- 2010-2014 GMC Sierra
- 2010-2014 GMC Yukon
- 2010-2014 GMC Yukon XL
GM, in calling for the class action lawsuit’s dismissal, stated “the truck has not needed any other repairs, and plaintiff has never had an oil consumption test performed” on the allegedly affected vehicle. The company’s statement added “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.”
Three similar lawsuits have been dismissed recently, including a suit in Alabama dismissed on the basis of the statute of limitations. A suit in Georgia was ended when the judge said the plaintiffs failed to produce evidence of their claims, while the dismissal of a Virginia lawsuit two years ago resulted from the plaintiff having “no injury in fact to support any of his claims” since the 2013 Chevy Silverado involved never had its oil consumption level tested.
If the allegations are true, the excessive oil consumption could critically reduce oil levels, allowing the engine to overheat and friction to occur, possibly damaging engine components.
