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 2013 and experiencing the same problems only have a 118, 000 miles on it and get vehicle maintenance , keep misfiring and lifter sticking , dealership won’t to charge me $10,000 to fix
I was wondering why my 2010 Tahoe would start hesitating when the AFM kicked in. I had to replace my lifters. This is not the way to keep a relationship going GM. Please let me know if I am eligible to be added to this law suit.

2010 Yukon XL 6.2 AWD
Numerous of problems with oil consumption. This results in exactly as described in article, “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.”
Engine destroyed. What to do now since no recall was issued and No vehicle, No work- GM should be accountable for engine failures.
I have a 2011 Suburban 1500 and have replaced the oil sensor and once again check engine light is on and I am leaking oil.
I am so fed up with these repairs. Please tell me if I am qualified for the class action.
I own a 2010 silverado 4×4 with 5.3 ltr engine and am experiencing an AFM nightmare. Replaced lifters and still have oil consumption issues along with random misfire, smoking exhaust etc., I am at a loss on what to do next other than an expensive engine swap.?
I have a 2013 Silverado that engine went out on me after 5 years of having the truck. I did everything, with the oil changes and keeping my car up to date on its maintenances. And I being charged 6k to put a new one in.
I have a 2013 suburban that i have to add oil on between oil changes. Replaced spark plugs I’ve spent $1000’s of dollars. Can i get on this class Anton lawsuit
There are alot more problems than that. Abs discontinued parts for 2010 can’t fix bullshit and many other problems
I purchased a 2012 1500 Suburban with 5.3L V8 a little over two years ago. I did my research and hadn’t heard of the lifter issues. Within a week my truck was back at dealership with oil pressure issues. Within a few months the lifter tick started. I’ve always serviced my vehicle on schedule. Last summer, misfire cylinder 7. Replaced spark plugs, coil packs and wire, did another oil change and replaced the oil pressure sensor. A month ago, code P0300 and P0301 and again P0307. I’ve had to add at least a 1-2 quarts of oil in between oil changes and have babied my truck after reading about the lifters and afm issues. All my attempts FAILED, only a matter of time I suppose. Lifters have failed, I’m waiting to see the amount of damage I’m going to have to come out of pocket and I’m still paying on it! GM needs to be held accountable for their flawed design and defects! I would like to be added to lawsuit if possible.
