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.

Add me to the list my truck had this problem
Hello , I have a 2012 Chevy Silverado and it burns oil bad I change the oil every 3,000 miles and it’s usually 2.5 quarts low so I’ve been adding oil between changes truck only has 100,000 miles
I own a 2014 Chevy Tahoe LTZ. My engine has a problem with oil burning through a piston which causes the spark plug to have to be replaced. This has occurred twice and costs up to $200.00 each time. GMC says that it will continue to occur until I replace the vehicle or the motor. Both of which I feel are not normal. Please help me in resolving this problem.
Our 2014 Chevy Tahoe is completely verified to have this oil consumption problem. Saw the “Low oil pressure” light come on and took to shop ASAP. 3 1/2 quarts low without any warning and now all that oil in in the engine and has done damage. Will be replacing all the oil filters with this GM kit. May have to replace or rebuild the engine!!
It isn’t just these years. I have a 2008 Yukon XL and 2008 Saab 97x both with 5300 and both consume oil like crazy. My saab had a lifter failure around 105k miles that cost me $2200. Here we are at 145k miles and another lifter failure and it’s sitting in my driveway because I don’t have the $2200 to fix it…again.
I have a 2012 Chevy Traverse that is burning oil already replaced the motor once.
2013 Silverado burning oil, changed sensors, sparkplugs multiple times, cleaned intake cover with tons of burnt oil in it.
2014 silverado. Multiple issues with AFM. Makor motor rebuilds among other issues.
Add me! This happened to my 2011 suburban and in shop as we speak. Costly repair of$2,200. Had to have it towed 65 miles ($360) because we were headed on a trip. Got stranded on side of road for 24 hrs with 5 kids and a hot day in AZ.
