General Motors Fuel Management Lifter Class Action Lawsuit Overview:

  • Who: Owners of certain GM vehicles are suing General Motors LLC.
  • Why: The drivers say their cars were fitted with defective fuel management lifters, breaching federal warranty laws and putting them in danger.
  • Where: The lawsuit was filed in Michigan federal court.

General Motors knowingly sold vehicles with engines containing a dangerous fault in the fuel management lifter, putting drivers in danger, a new class action lawsuit alleges. 

Plaintiffs Danny Harrison, Christopher McClave, Melissa Luster, Leon Jordan, Daniel Demarest, Mark Hayford, Ronald and Marilyn Jett, and Rebecca Prosser filed the class action lawsuit against General Motors LLC Dec. 15 in a Michigan federal court, alleging the auto giant omitted material facts about faults in its cars. 

The plaintiffs are looking to represent anyone who purchased or leased any 2014 to 2021 Buick, Cadillac, Chevrolet and GMC vehicle equipped with a 5.3L, 6.0L or 6.2L V8 engine.

GM made and sold these vehicles without disclosing that their Active Fuel Management lifters (AFM Lifters) were defective in design, the plaintiffs say. 

“The Valve Train Defect can leave drivers and passengers in dangerous situations,” they say in the lawsuit. “For example, stalling, losing power while driving and hesitation, especially when trying to merge, increase the risk of a traffic collision.” 

If the issue is unremedied for too long, the entire engine can be damaged, necessitating an expensive full engine replacement, the lawsuit alleges. 

Plaintiff Claims The Lifter For the No. 3 Cylinder in His GMC Sierra Collapsed

Plaintiff Harrison says he bought a new 2021 GMC Sierra 1500 on Feb. 9, 2021. However, five months later, he was driving his vehicle on a 20-mile-long bridge located 250 miles from his home when the vehicle began to sputter, spit, vibrate, misfire and lose power. 

“Plaintiff Harrison was only narrowly able to get the vehicle off the bridge, where he called his local GM authorized dealership, Tameron Buick GMC, for assistance.The lifter for the No. 3 cylinder had collapsed,” the lawsuit says.

It says that when the Valve Train Defect manifests during the warranty period, GM authorizes its dealerships to merely replace the parts that have failed with the same defective versions. 

“As a result, the Valve Train Defect manifests again, often outside the warranty period,” according to the lawsuit.

The plaintiffs are suing for breach of warranty and violation of state consumer laws. They’re seeking certification of the class action lawsuit, damages, fees, costs, interest and a jury trial.

    I own a 2018 Tahoe I purchased from a dealer with 41,000 mile on it in 2019. I purchased the extended warranty. It now has 53,000 miles, and I have noticed a lifter ticking sound. After reading about the lawsuit, and how they only repair with same defective parts, I fear I may be next. Can I join this suit?

  3. Carl J Wolfe III says:

    I purchased a 2015 Chevrolet Silverado with the 5.3L. I have almost 150k on it and I fell that I am starting into the lifter issue myself. I have already had to do a transmission flush that ended up coming out of my pocket as the issue came up right after the warranty expired. The dealership told me they knew of the issue but because it usually happened under warranty.

  4. Jorgen Q says:

    2019 Silverado Lt. no issues as of yet since it only has 14800 miles on it, warranty is about to go. I did had them fix some paint issues when the truck was only 5 days old.

    1. Sean Smith says:

      Same here. We bought a 2021 Yukon AT4 and a lifter went at 7,500 miles. Repaired all 16 under warranty but it still doesn’t run right. We’ve had electronic issues, air ride suspension issues ever since that day. I love the truck, it’s honestly out favorite vehicle we ever purchased until this. I want it lemon lawed in the worst way.
