A class action lawsuit filed against General Motors alleges that 2010 through 2013 vehicles with “Generation IV 5.3 Liter V8 Vortec 5300 engines” are defective. The complaint asserts that “the piston rings, PVC system, and Active Fuel Management (‘AFM’) System used in the Class Vehicle’s engines were defective causing excessive oil consumption, premature spark plug degradation, and engine malfunction.”
Vehicles covered by the complaint include 2010-2013 models of the:
- Chevrolet Avalanche,
- Chevrolet Express 1500,
- Chevrolet Silverado 1500,
- Chevrolet Suburban,
- Chevrolet Tahoe,
- Chevrolet Colorado,
- GMC Yukon,
- GMC Yukon XL,
- GMC Sierra 1500,
- GMC Savana 1500, and the
- GMC Canyon.
The GM oil consumption class action lawsuit states that oil is necessary for a car engine, but can be disastrous if it gets inside the combustion cylinder. The complaint notes that auto manufacturers use several items, including “valve guide seals and piston rings” to keep this from happening. According to the complaint, that is because if the seals fail, “it results in a loss of lubrication throughout the engine which, in addition to destroying the engine, may cause loss of power during acceleration, white or other colored smoke to be emitted from the exhaust, and the vehicle entering a ‘safe mode’ where the engine may suddenly shut-off or run improperly until the issue can be addressed by a mechanic.”
This is exactly what happens to the defective General Motors automobiles, the class action contends. The complaint asserts that first, defective piston rings allow oil to enter the engine’s combustion chamber, where it should not be. Second, the PCV system is in a defective location, also allowing oil into the combustion chambers. And third, a defect in the AFM system allows oil to gather in cylinders when they are not in use. The class action claims that these problems were made even worse by GM’s “oil life monitoring system,” which supposedly tracks oil consumption and tells drivers when they need to get a car’s oil changed.
Plaintiff Bradley Zierke states that he bought a new 2012 Chevrolet Avalanche. Zierke claims that he has to put oil into his vehicle every 1,000 to 1,500 miles, has had to replace spark plugs three times, and after only 87,000 miles he had to replace the entire engine. The complaint asserts that Zierke would not have purchased the truck had he known the truth about the oil defect.
Affected vehicles include the 2010-2013 models of the Chevrolet Avalanche, Express 1500, Silverado 1500, Suburban, Tahoe, and Colorado, and the GMC Yukon, Yukon XL, Sierra 1500, Savana 1500, and the Canyon.
The class action alleges that GM knew of these defects, and corrected the issues for 2014 model vehicles. The complaint notes that General Motors issued “at least seven Technical Service Bulletins from 2010-2013 to address Class Vehicles’ excessive oil consumption.” The class action asserts that despite this knowledge, and that the engine defects should have been covered by GM’s warranty, the auto manufacturer has failed to issue a recall or otherwise address consumers’ concerns.
The oil consumption defect lawsuit requests certification of a class of all people in the US who either currently own or lease a General Motors vehicle affected by the oil defect, or previously owned or leased such a vehicle and had to pay for extra maintenance or repairs. The class seeks restitution and damages, as well as an injunction stopping the unlawful conduct by GM.
Zierke is represented by David H. Grounds and Timothy J. Backer of Johnson Becker, PLLC.
The General Motors Oil Consumption Defect Class Action Lawsuit is Bradley K. Zierke v. General Motors LLC, et al., Case No. 0:16-cv-04170, in the U.S. District Court for the District of Minnesota.

I have a 2010 Chevy avalanche and oil pressure very low 15-18. Can’t seem to figure out after replacing sensors etc. Don’t dare to drive it anywhere. Have spoken to chev garage and other garages. Price for guess work has gotten way out of hand. I would have never bought this truck had I known!!
I have a 2010 GMC Sierra 1500 denali with the 6.2L that started blowing out white smoke of the exhaust last week. I had it rollbacked to the dealer that i purchased the car from 3 years ago. The car only has 109K miles. The dealership is saying that oil is getting into the chamber do you worn piston rings. The estimated cost of repair is roughly $6K – $7K. SA replacement engine will cost roughly $11K.
What were the rulings by the courts and what actions did the court demand of GMC.

My 2013 GMC Sierra has very low miles and started knocking the other day and sounds like engine going to blow! I always change oil every 3000 miles! Uses a quart in between changes! My transmission is a nightmare banging in and out of gear! I’m surprised nothing has broke its very loud and violent! It happens when you try to pick up speed or pass someone! The truck lurches like your applying the brakes and engine idles down then you here and feel loud bang and it takes off! Does it 1 out of every 4 or 5 times! I have to use the auto shift button and manually change the gears to prevent this from happening! I paid over $24,000 for this a couple years ago and it definitely should not be needing a transmission or a engine after paying that kind of money! Gmc knows about these issues and ignores it! They should take responsibility for their inferior crap product but they won’t until they forced to! So sad some auto manufacturers seem to care and do what’s needed to make their customers whole again so they feel confident enough in future to buy another vehical from them!’ Gmc Chevrolet don’t care about their customers and it couldn’t be more obvious! Nothing short of theft!!!’ Selling you something that’s crap for all the money!!!!
