Drivers have launched a class action lawsuit against General Motors, claiming that the powertrains in some Chevrolet, Cadillac, and GMC vehicles are defective, causing an unpleasant driving experience known casually as the “Chevy shake.”
The Chevy shake class action lawsuit was filed by Kim Bostick and Branden Jamison who say that they purchased vehicles affected by the defect.
According to Bostick and Jamison, General Motors leased and sold hundreds of thousands of vehicles that are equipped with defective drivelines or powertrains — the part of the vehicle responsible for turning the vehicle’s wheels. Allegedly, this problem causes the vehicles to shake violently when driven at high speeds.
Bostick and Jamison go on to describe the “Chevy shake” defect in more detail, claiming that the problem is caused by a defective drive shaft that is part of the driveline.
According to the plaintiffs, the drive shaft is an aluminum tube running the length of the interior of the vehicle, “transmitting torque and rotation from the engine to the wheels.” The drivers say that when the output shaft of the transmission rotates, it spins the drive shaft, turning the differential ring gear to rotate the wheels.
To work correctly, the drive shaft must reportedly be designed to particular balanced and weighted standards, so it can perform at high speeds. However, the design of the GM drive shafts in question allegedly are not appropriately designed.
The GM driveline shake class action lawsuit says that because of their defect, the vehicles are unstable at highway speeds and can cause drivers to lose control of their vehicles.
Allegedly, the problem can worsen over time if it is not fixed. The drivers say that the defect in the design can cause the drive shaft to deteriorate, which can cause the powertrain to completely fail by the drive shaft dropping to the ground. The drivers say this occurrence makes the vehicles unusable.
The vehicles that reportedly possess the Chevy shake defect include the following:
- 2015 to 2020 Cadillac Escalade
- 2014 to 2019 Chevrolet Silverado
- 2015 to 2020 Chevrolet Suburban
- 2015 to 2020 Chevrolet Tahoe
- 2014 to 2019 GMC Sierra
- 2015 to 2020 GMC Yukon or Yukon XL
GM allegedly knew or should have known about the defect in the driveline because of testing that the company should have conducted on the vehicle before it was released onto the market.
Additionally, GM knew or should have known about the problem at least after the vehicles were released onto the market because numerous complaints were made about the problem and communicated to GM, say the drivers.
The GM driveshaft class action lawsuit claims that GM actively concealed this information from consumers. The drivers state that GM put its own profits ahead of the safety and financial interest of customers.
The plaintiffs say that had they known their vehicles were defective, they would not have purchased them or would not have paid as much as they did for them.
In April, GM drivers filed a separate, similar Chevy shake class action lawsuit.

We have a 2014 GMC Sierra and once you hit around 70-80 it shakes so bad I have poured boo koo money into trying to figure this out.
I have a 2016 Chevrolet Silverado. Had maintenance while under warranty for the “shake” (the mechanic drove and verified the vibration). Dealer flushed the transmission. Being retired and not driving much on highway, I notice the problem never really went away. Now, out of warranty, the dealer wants to drop the transmission pan for about $300 just to see if any metal is there. Seems I’m getting charged for diagnostics that are existing and known issues. This is wrong to not admit the issue upfront.
I have a 2015 Chevy Suburban and it shakes around 74-80. I have had the tires re-balanced and it still does it.
Have 2014 chevy silverado 1500 shakes at 70 to 75 mph all the time
I have the same problem in my 2016 2500 h.d. Silverado 70 miles per hr it starts.
Complained early on after purchasing my 2015 GMC Sierra. Forced the dealers senior mechanic to take it for a drive, and he gave me some bullshit about the engine mounts harden after 2 years and cause the shaking. I told him and the manager that was crap and they knew it. Sign me up for the class action suit. Groveland, FL
I have had my 2018 silverado in the shop a couple times for the shake. There answers are tires need rotated. Did that and it did nothing. They are full of excuses.
I have a 2016 GMC 1500 Denali with the 8 speed automatic and 5.3 engine. The vibration problem keeps getting worse and I can seem to find an answer to fix it. I was just about to replace the electronic front shocks and perhaps the wheel bearings. I have replaced the tires and had them rebalanced several times with no improvement.
Add me!!!
I’m so glade i come across this post I’ve wasted so much money trying to fix that stupid shake problem new tires, new rims, wheel bearings, numerous wheel balances, brakes, rotors, & all new front end ball joints A-arms steering rods & coils n shocks. all a waste of money this totally makes sense. I still have the truck I don’t take it much over 55 mph & when I have to drive the interstate everyone hates me cause here in Texas the speed limit is 75 mph & some places 85 mph. when the truck was my only vehicle there were certain jobs I couldn’t accept because of the dang CHEVY SHAKE. ill give more of my info if i hear back
PS I still have receipts of all the work I put into this truck because of this issue
