General Motors may have sold you a defective vehicle.

As early as 2016, drivers of General Motors cars, trucks and SUVs noticed that their vehicles were experiencing the “Chevy Shake.” 

If you google “Chevy Shake,” you will get over 6 million results. Several drivers filmed their vehicles shaking and shuddering while driving. The steering wheels sometimes shook violently and alarmed drivers. The problem often occurs while driving over 35 miles per hour, even in cars with less than 1,000 miles on them. However, some consumers have reported shuddering at speeds as low as 25 miles per hour. Many news outlets have since reported on consumer complaints about the “Chevy Shake” and borrowed footage uploaded by Cadillac, Chevy and GMC owners.

Multiple class action lawsuits allege that GM’s vehicles are defective and difficult for drivers to control. Initially, the cause appeared to elude consumers. The class action lawsuits later named two possible causes: an aluminum driveshaft and an 8-speed transmission.

In particular, consumers have nicknamed the Chevy Silverado the “Shake-arado.” If your GM vehicle has experienced the Chevy Shake, you are not alone. You may be included in one or more class action lawsuits. Knight Law Group can help you opt out, preserve your lemon law rights, and recover a significant cash settlement.

2. Why should I opt out of a class action lawsuit?

You have to opt out if you want to retain your right to sue individually. If you stay in the class action, you waive your right to sue as an individual both during and after the settlement. Additionally, class action lawsuits often have thousands of members. If you stay in a class action lawsuit, you may only get a meager cut of the final settlement.

3. How would some 8-speed transmissions cause the “Chevy Shake”?

Francis v. General Motors alleges that the “Chevy Shake” is caused by 8-speed transmissions. The 8L45 and 8L90 transmissions allegedly cause significant shaking and shuddering in some SUVs and trucks. Sometimes, the shaking is so violent that drivers feel like they have been hit by other vehicles.

This problem can occur when a driver is speeding up, slowing down, or trying to shift gears. One driver said that the harsh shift from “reverse” to “drive” nearly made him drive through his garage door.

Recent news reports also dubbed this symptom the “Chevy Shake,” with one investigative reporter receiving more than 90 complaints about the problem in his state alone. Jason Stoogenke of WSOCTV9 reported on the “Chevy Shake” in 2019. Since then, he has received more than 90 complaints about the “Chevy Shake.”

4. How would an aluminum driveshaft cause the “Chevy Shake”?

Kim v. Bostick alleges that the “Chevy Shake” is caused by a faulty aluminum driveshaft. The aluminum driveshaft allegedly causes such violent shaking that drivers lose control of their vehicles.

This component is also known as the “propeller shaft” or “prop shaft.” The driveshaft is intended to transfer power from the engine to the wheels, making the wheels spin. 

However, violent shaking causes the aluminum driveshaft to deteriorate over time. The driveshaft then drops to the ground and makes the vehicle undriveable. 

Complaints about Chevy Shake were reported to news outlets as far back as 2017. Jessica McMaster of 41 Action News interviewed several consumers and showed footage of the “Chevy Shake” problem. One consumer nicknamed his Chevy Silverado the “Shake-arado.”

5. Has General Motors fixed the Chevy Shake issue?

The short answer: No. 

General Motors issued many technical service bulletins, or TSBs, for vehicles with faulty 8L45 and 8L90 transmissions. These TSBs advised dealers to flush the old fluid out of these transmissions and replace it with a newer type of transmission fluid. However, this fix failed to resolve the problem in many affected vehicles with these 8-speed transmissions.

As for the aluminum driveshafts, consumers are left on their own. Many drivers had to shoulder out-of-pocket costs for custom steel driveshafts. If a manufacturer is responsible for a widespread problem in certain vehicle models, then the manufacturer should come up with a solution. In this case, General Motors left the problem for consumers to solve.

6. What do these Chevy Shake class action lawsuits mean for me?

If your Cadillac, Chevrolet or GMC vehicle is experiencing the Chevy Shake, you may be a member of at least one class action lawsuit. If a suit becomes certified, that means a judge has approved the suit to go forward. Members who stay in class action lawsuits get a portion of the final settlement, but lose their right to sue individually for the problem. You will have to opt out of one or more class action lawsuits to preserve your individual lemon law rights.

Opt out of your class action lawsuit.

If you opt out of the Chevy Shake class action lawsuits, you can sue for charges more specific to your situation. As a result, you may receive a greater settlement. The California Lemon Law allows drivers of defective vehicles to receive cash compensation, a vehicle replacement or a lemon law buyback. Knight Law Group can help you opt out and retain your California lemon law rights.

7. How do I opt out of a class action lawsuit?

If you are affected by a class action lawsuit, you may receive a notice. This notice outlines the allegations and tells consumers that they can opt out of the class action lawsuit. Though these notices usually contain instructions for opting out, you should consult an attorney on the specifics. An attorney can tell you how to opt out and what deadlines you should know.

Once you opt out of a class action lawsuit, you can request a free consultation on your current legal options.
