The Chevy Shake:
What You Need To Know

Why do some vehicles experience the "Chevy Shake"?

Multiple class action lawsuits allege that Cadillac, Chevrolet and GMC vehicles experience a defect called the "Chevy Shake." In other words, these vehicles may shake violently, particularly when being driven at highway speeds.

In addition to the Chevy Shake, these vehicles may experience the following defects:

  • Harsh Engagement
  • Harsh Shifting
  • Delayed Upshifts
  • Transmission Slipping
  • Clunks While Shifting
  • Difficulty Stopping
  • Jerking While Changing Gears

These lawsuits allege two possible reasons for the Chevy Shake: a faulty 8-speed transmission, or a weak aluminum driveshaft. In the case of a faulty driveshaft, it may deteriorate over time, drop to the ground, and render the vehicle undriveable.

Why should I opt out of a class action suit?

Failure to opt out of one or more class action lawsuits may lead to you losing your right to pursue an individual claim.

Class action lawsuits often have thousands of members, among which you may have to split the final settlement. As a result, you may only get a meager cut. If you opt out and preserve your right to sue individually, you may sue for charges more specific to your situation and get a larger settlement.
