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.

I have a 2019 LTZ Crew cab 6.2L 10 spd transmission. Experienced teeth rattling shaking at between 65-80 mph. Twice in same direction of ny throughway eastbound. Just before 690 exit. Since it was the same stretch of highway I assumed it was the highway, but after reading this it makes me wonder.
This problem goes back before 2011. I have a 2005 that has the same issue. In my 2011 I had to replace, the entire rear…..
My 2017 GMC Evolution has the shake at 70 mph and it also down shifts hard at times. Iv asked the dealer about it and was blown off about it.
I have the same problem with mine they also turned their heads told me it was the tires at Amesbury chevy in mass. I am a tire installer with a brand new balancer and a hunter alignment machine. The truck shakes when all 4 tires are jacked up off the ground in drive . So its not the tires.
I own a 2014 Silverado LTZ Double Can and it has the Chevy Shake also. Happens from about 72 mph up to about 94 mph. I’ve brought it to 4 different dealerships to be checked out. 3 of them blew me off and the 4th said that they didn’t experience it when they road tested it.
I owned a 2017 gmc sierra 1500 z71 with the problem. I got fed up and sold it. Bought a 2019 Ram
I own a 2014 Silverado that has this problem. I went to 4 different dealerships with it to be checked out. All 4 of them said that there was nothing wrong with it.
My 2018 Z71 Crew cab Silverado has had the “Chevy Shake” since day one. We mentioned it during the test drive and we’re told it was the tires and it would subside shortly. At this point I’ve been denied and repair after being to dealer multiple times. Even went for a ride with the local GM representative and was told it was normal. It shakes sooo much at 75+ it’ll make a half full can rotate in the cup holder.
2016 Silverado z71 crew cab 1500 shakes at 70mph took to dealership numerous times kept blaming tires road forced balanced them at 3 different shops even went as far as buying new rims and tires and road force balancing 2x still nothing was done to fix or even attempt to fix
They did the same for my truck and finally told me it was within acceptable levels and there was no further repairs needed.
I owned 2o15 Silverado . Did this all the time and transmission was junk . To point didn’t feel safe take down the road .Dealership told me it was up to gm standards nothing wrong it . Ive work in automotive industry my whole life owed all kinds gm trucks never did this . Sad guess my 78 Chevy with Lord knows how many miles twice the truck smooth driving paid 2500 and way better than 30000 thousand dollar truck . Sad but took a big lost had to roll over money on a Honda Civic feel like gm should pay for difference
Yes my 2016 Chevy Silverado 1500 ltz has the shake at higher speeds.
