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.

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]:
