GM put a defective Vortec engine that burns through oil in seven popular GMC and Chevy vehicles made between 2011 and 2014, according to a nationwide class action lawsuit.
Lead plaintiffs Jared Hammond, Steven Newberry, Rey Cruz, and Lyndon Adamson lodged the vehicle safety defect class action lawsuit in Michigan federal court Thursday. They claim that General Motors Corporation (GM) knew from earlier experiences with the Vortec engine that it consumed an “abnormally and improperly high quantity of oil,” but put the defective part in later models anyway.
Each of the plaintiffs claim that they purchased a GMC or Chevy vehicle that came with a Generation IV Vortec 5300 Engine. They say that the piston rings in the Vortec engine do not keep oil in the crankcase.
In addition, the plaintiffs allege that the Active Fuel Management system in the Vortec engines contributes to the problem by spraying oil directly on the piston skirts.
“This oil spray overloads and fouls the defective piston rings, triggering oil migration past the rings,” explains the class action lawsuit. “The migrating oil either burns or accumulates as carbon buildup on the combustion chamber’s surfaces.”
A process meant to vacuum atomized oil from the valvetrain into the intake system further exacerbates the excessive oil consumption problem in the Vortec engines. In addition, GM’s “Oil Life Monitoring System” fails to warn drivers until oil levels are critically low.
The class action lawsuit alleges that 2011 through 2014 models of the following vehicles made by GM were equipped with the defective Vortec engine:
- Chevrolet Avalanche
- Chevrolet Silverado
- Chevrolet Suburban
- Chevrolet Tahoe
- GMC Sierra
- GMC Yukon
- GMC Yukon XL
The plaintiffs claim that excessive oil consumption by the Vortec engine results in low oil levels, insufficient lubrication, and internal engine damage.
This is far from the first Vortec engine defect class action lawsuit lodged by owners against GM over excessive oil consumption. Earlier this year, consumers from Ohio and West Virginia lodged similar complaints.
The plaintiffs in this class action lawsuit seek to represent those who purchased or leased a GMC or Chevy equipped with the allegedly defective Vortec engine. The class action lawsuit wants to hold GM responsible for damages as well as attorney and court fees.

2011 Yukon engine is having internal issues the shops says.
I have a 2011 Sierra SLT 4×4. Check engine light flashes. Random multiple cylinder misfire. I have changed plugs, and wires coil packs. Some of the spark plugs were melted. I’ve never seen that before. The whole AFM design is seriously flawed. It may have looked good on paper, but it is a terrible design. Destined to fail, and that’s just what happened. I would love to know how to get in on this class action law suit. Thank you
2014 Silverado: The AC compressor locked up and shredded flakes of metal throughout the system in 2019, oil pump was on the verge of not working in 2021, and now the torque convertor came apart and I am having to replace the transmission. Total cost me $7800. I need GM to take responsibility.
Exact same thing just happened. 7100
I have a 2013 chevy silverado that the engine is ticking loud. How do I get in on this suit.
I financed a 2014 chevy 1500 silverado in 2017 and have had to pay for engine mounts, air compressor, starter switch and now I need a rack and pinion. I would love to be a part of the class action lawsuit for this vehicle. I am the second owner of the vehicle. It had 117,000 miles on it when I financed it in 2017..
I have a 2014 Chevrolet Silverado that I have had to put lifters and due to lifter sticking ask chevrolet company here local And said that they could not warranty it because because they were not known to be a problem But I’m still having problems with lifters and Random misfire only DOD cylinders
I have a 2012 avalanche that burns 1.5quarts every 3000 miles. Also lifter tapping.
I had a 2012 Chevrolet Silverado. 3k in repairs due to the tip of a spark plug breaking off. The engine was overheating due to lack of oil even though the truck didn’t warn it was low. The repairs from the dealer said the heads and piston rings needed to be replaced and that it was a very common issue.
I had a 2010 equinox with oil consumption issues.
I now have a 2014 GMC Terrain with oil consumption problem, among other mechanical issues.
Please add me!
I have a terrain with 2.4L eco tech that have the excessive oil. Every week or 2 I have to put qt to a qt and a half.
