Update:

  • Three classes of General Motors (GM) vehicle owners asked a California judge to throw out GM’s request to overturn a $100 million jury verdict.
  • The classes’ filing told Judge Edward Chen of U.S. District Court in the Northern District of California that it believes expert testimony is not needed for a class action case to succeed.
  • It also states that recent rulings throwing out defect claims in BMW and Mazda vehicles are not the same and do not apply.
  • The filing claims GM’s own witnesses testified the engine defect would occur, leading to the vehicles’ engines consuming an excessive amount of oil.
  • GM attempted to block the verdict, which would have awarded $2,700 each to class members who owned certain versions of GMC Sierra, Yukon and Yukon XL and Chevrolet Avalanche, Silverado, Suburban and Tahoe.

GM engine defect class action lawsuit overview: 

  • Who: A California federal jury awarded $100 million to three classes of General Motors (GM) vehicle owners. 
  • Why: The vehicle owners claimed GM sold vehicles with hidden engine defects that caused them to use an excessive amount of oil. 
  • Where: The class action lawsuit was filed in California federal court. 

(Oct. 6, 2022)

General Motors (GM) has been ordered to pay more than $100 million to classes of vehicle owners who argue the company sold vehicles with defective engines. 

A federal jury in California delivered the verdict against GM after less than one day of deliberation. It will benefit three classes of around 38,000 GM vehicle owners from California, North Carolina and Idaho, Law360 reports. 

Vehicle owners, who will receive $2,700 each, had accused GM of selling vehicles — including certain of its GMC Sierra, Yukon, Yukon XL and Chevrolet Avalanche, Silverado, Suburban and Tahoe — with a hidden engine defect that caused them to consume an excessive amount of oil. 

Jurors determined that GM breached its implied warranty and implied warranty of merchantability with the vehicle owners and violated Idaho’s consumer protection act, Law360 reports. 

Vehicle owners claim GM engine defect hidden from the public 

The vehicle owners claimed GM hid a defect in engines the company introduced in 2007 while the automaker reportedly argued that it discovered and fixed the problem. 

The vehicles at the center of the GM engine defect class action lawsuit include trucks and SUVS sold by the company between 2011 and 2014 that contained a Generation IV Vortec 5300 LC9 engine, Law360 reports. 

An engineer for GM reportedly testified during the trial that the automaker developed a cleaning process as a potential remedy to the defect that turned out to not be effective but was less expensive than a different potential fix. 

A separate class action lawsuit filed against GM escaped dismissal last month after a federal judge in Georgia mostly denied the automakers motion to dismiss claims it made defective engines.

    I have a 2018 Chev Silverado with rattling lifters. My local dealer has done all my service work since they sold it to me. I have it serviced religiously as recommended. I have been told the repair cost is $3500.00 to $4000.00. That is ridiculous. I’m 72 years old drive at stated speeds and do not abuse my truck.

  3. Colton Moran says:

    I have a 2015 Chevy Equinox that just had its Engine blow due to oil burn. Will cost $7k to replace. Looking to be a part of this class action. It was purchased in California in 2019.

  4. Karen King says:

    I have a 2014 Chevy traverse that has had an oil consumption problem since I purchased it brand new I had it into the shop several times and they told me that the oil consumption was normal and could not find anything wrong. I religiously check my oil now every 2000 miles and add oil as needed but I was wondering why the traverse wasn’t considered in the lawsuit? There’s an actual traverse blog site where everyone talks about the same issues. It has been a real inconvenience for years, especially when traveling outside the state.

  5. Larry Heaps says:

    I have a 2015 Yukon Denali XL with the 6.2L with AFM, 165K miles, under acceleration from a stop you can clearly hear a rattling knock from the lifters until the oil pressure increases in the vale train. I’m praying everyday that I don’t wipe out the camshaft or pushrods. I have religiously done oils changes with Royal purple 0w-20 and Lucas Oil super syn additive. My father has a 2014 that the lifters failed and he paid personally to replace.

  6. Rich says:

    My lifters were misfiring and I had to get a brand new engine for my 2012 Suburban. I’m hoping we can get reimbursed for this non sense. My Father’s 2001 Suburban still runs great because it doesn’t use AFM.

  7. Teisha Swindle says:

    I live in Michigan and I’m not sure if this settlement applies to Michigan residents, but I own a 2015 Chevrolet Tahoe LTZ and the excessive oil consumption is just one of many problems that I’m having.

  8. Kelly says:

    Have a 2011 Chevy Silverado 5.3 burns over a quart of oil in 3k had 75k on engine

  9. Jordyn says:

    This happened with our 2016 Equinox. First, it was the windshield wiper falling off in a rainstorm on the highway (which DID get recalled), then it was a $3,500 repair for engine issues on the piston rings (they cracked and leaking), after that repair, it was about 3 months before the excessive engine oil consumption and a potential $11,000 repair of the engine, then it was spending months hoping to salvage the car because we couldn’t afford a new engine by putting more oil in the engine after every ride, then it was the timing chain, etc. There are SO many things that went wrong with this car that were due to defects. The car was purchased for $16,000 and only had 110,000 miles on it when we had to trade it in for a new car. Which we made sure to stay away from GM. Absolutely criminal with how many people are having the same issues country-wide. We are in Wisconsin where no class actions have been filed for this case unfortunately.

  10. Chelsea Connor says:

    Purchased a used 2016 Chevy equinox and I am now having oil consumption issues. No mention of this on the Carfax what can be done what GM reimbursed me in anyway or make repairs to correct the issue?
