Drivers in a GM oil class action lawsuit say their Chevrolet Silverado vehicles consumed excessive amounts of oil due to a defective engine.
Plaintiffs Lisa Mae Jennings and Airko Inc. say their 2013 Chevrolet Silverado trucks suffered from excessive oil consumption due to a defect in their engines. The Generation IV Vortec 5300 engines found in these trucks allegedly contain a defect which causes the oil issues — in turn leading to engine damage.
Jennings says she experienced the GM oil defect in her 2013 Chevrolet Silverado vehicle, which she purchased new. Jennings allegedly noticed the oil consumption issue for the first time in 2016, while the vehicle was still under warranty.
Since then, Jennings has reportedly suffered from numerous problems with her engine that all link back to the oil problem.
Over the course of normal operation, Jennings has allegedly suffered from a broken camshaft, failed lifters and rough idle — all of which she contends are a result of the oil defect. Due to these problems, she has reportedly had to replace the camshaft, lifters and spark plugs in her vehicle.
Airko — an Ohio company — allegedly experienced a similar issue with its 2013 Chevrolet Silverado, which was purchased used in 2016.
Mechanics for the company claim to have informed leadership that their truck consumed an “unusually high” amount of oil. Later on, the vehicle’s engine reportedly failed completely. After further inspection, this failure was attributed to a loss of lubricity from low oil levels.
According to the plaintiffs, this issue does not affect only Chevrolet Silverado vehicles. The plaintiffs contend the Chevrolet Avalanche, Chevrolet Suburban, Chevrolet Tahoe, GMC Sierra, GMC Yukon and GMC Yukon XL vehicles all are affected. In fact, the class action lawsuit notes several online forums contain stories of similar GM oil consumption problems.
The GM oil defect allegedly stems from a problems with the piston rings in Generation IV Vortec 5300 engines. These rings allegedly fail to serve their intended purpose of keeping oil in the crankcase of the engine. As a result, oil allegedly migrates past the rings where it can burn or accumulate in the engine’s combustion surfaces.
“[T]he Class Vehicles were engineered to fail,” the GM oil class action lawsuit contends. “GM failed to disclose the truth about these vehicles and failed to remedy the well-established defects in the Class Vehicles that were on the road.”
The plaintiffs claim that GM knew or should have known about the defects in their vehicles’ engines but failed to take steps to remedy the issue or inform consumers.
As a result, consumers like the plaintiffs were reportedly deceived into purchasing the affected vehicles based on false promises and expectations.
The GM oil class action lawsuit contends this deception caused financial harm to consumers who paid more for the vehicles than they were worth.
The plaintiffs seek to represent a Class of Ohio drivers who purchases or leased a Chevrolet Silverado, Chevrolet Avalanche, Chevrolet Suburban, Chevrolet Tahoe, GMC Sierra, GMC Yukon and GMC Yukon XL vehicle. According to the GM oil class action lawsuit, there could be thousands of Class Members.
This is not the first time GM has faced a class action lawsuit over its alleged oil troubles.
In 2019, another plaintiff argued that he and other Chevrolet and GM vehicle owners were harmed by a defect in their engines which caused excessive oil consumption. However, that case was dismissed earlier this month by a federal judge in the Northern District of Ohio.
Although that case was dismissed, plaintiffs’ lawyers in the current case remain confident their claims will succeed in court based on the success of similar allegations.

I have a 2015 gmc sierra denali. Got the oil and filter changed. Drove it 500 miles 6 days later to see family during the holidays without an issue. Started the truck up the next day and the engine didn’t sound right. Was heading to gmc dealership to get it checked out and the oil pressure light came on and the oil pressure dropped to zero and the low oil pressure turn engine off came on the display. I shut the engine off and checked the oil. The oil level was fine. Had the vehicle towed to the dealership. They tested it it and said there was no oil circulating in the engine. They put a new oil pump on and said it was fixed. I drove 8 hours back to pick the truck up. Started it up and it was still doing the exact same thing. Currently in a loaner they gave me waiting to hear back. I was telling my friends and family about this and two of them both had the same issue. One has a Silverado and the other a sierra. Looking on forums and this website this has been a known issue for years.
