Thank you to everyone who helped contribute to this investigation. At this point, attorneys working with ClassAction.org no longer need to hear from drivers who had this issue with their vehicles. Please view our open list of investigations here. The information below was posted when the investigation began and exists for reference only.
At A Glance
This Alert Affects:
Anyone who owns or leases certain Chevy or GMC vehicles that experience excessive vibration or shaking, especially when driving at highway speeds.
What’s Going On?
A class action lawsuit has been filed against General Motors (GM) over what’s known as the “Chevy Shake”—a suspected defect in certain Chevy and GMC vehicles that allegedly causes the cars to shake or vibrate when they reach high speeds. Attorneys working with ClassAction.org have opened their own investigation into the allegations and want to hear about drivers' experiences with the vehicles in the hopes of filing additional cases.
2015 to 2020 Cadillac Escalade; 2014 to 2020 Chevrolet Silverado; 2015 to 2020 Chevrolet Suburban; 2015 to 2020 Chevrolet Tahoe; 2014 to 2020 GMC Sierra; and 2015 to 2020 GMC Yukon and Yukon XL.
How Can a Lawsuit Help?
A class action lawsuit could help repay drivers for money they spent on repairs and force GM to fix the problem.
General Motors has been hit with a class action lawsuit alleging certain Chevy and GMC vehicles contain a defect that causes them to excessively shake or vibrate when driving at high speeds.

What Is the Lawsuit Alleging?
Some drivers who experience the “Chevy Shake” suspect that it’s related to transmission problems, but attorneys believe the shaking and vibration are caused by a defective drive shaft, which GM also refers to as a “propeller shaft” or “prop shaft.”
According to the lawsuit, some drivers have replaced the aluminum drive shaft in their vehicles with a custom steel drive shaft and reported that the repair was a “complete fix.”
The lawsuit claims GM, on the other hand, has known about the alleged defect for years but either refuses to fix the vehicles or replaces broken parts with similar defective ones.
Many drivers have turned to online forums to voice their complaints about the “Chevy Shake.” In fact, an online forum titled “Shake or Vibration Issues” on GM-Trucks.com has over 800 pages of complaints. Some of them can be read below [sic throughout]:
I have 20's goodyear on my 2014 LTZ 4wd. Vibration is terrible. Cant stand it. 1st time dealer said the tires were not perfectly round and replaced 3 of them. This didnt fix the problem. 2nd time at dealer and replacing the 4th tire. Not fixed! I spent alot of money for a truck that shakes between 50 and 80 mph.
