What is the “Chevy Shake”? The complaint for this class action alleges that certain Chevy vehicles shake violently when they reach interstate highway cruising speeds, due to defective drivelines and drive shafts in these General Motors, LLC vehicles.
The Nationwide Class for this action is all persons who bought or leased, in the US, one of the following:
A Florida Subclass has also been proposed, for those who bought or leased the vehicles in Florida.
The complaint defines the drive shaft as “an aluminum tube that runs the length of the interior, transmitting torque and rotation from the engine to the wheels. When the output shaft of the transmission rotates, it spins the drive shaft, turning the differential ring gear to rotate the wheels.” The drive shaft must be “precisely designed, manufactured, balanced, and weighted[,]” the complaint says, because it rotates at high speeds and torque values.
The complaint claims that the shaking is a safety concern because “drivers have reported that the defect makes the vehicles feel unstable at speed and can cause a loss of control.”
Worse yet, “an unaddressed drive shaft defect can cause the part to progressively deteriorate, culminating in failure as the shaft drops to the ground and renders the vehicle undriveable.”
The complaint notes the “thousands of complaints” on the website www.gm-trucks.com.
Although some of the complainants received replies from GM, they reported that when they took their vehicles in to GM dealerships for repairs, “GM representatives were unable to diagnose and fix the Chevy Shake defect. Consumers detailed that GM representatives would orally confirm the presence of the defect after a test drive but then later misrepresent the problem to avoid having to address it.”
The postings reproduced in the complaint often note that the defect occurs when vehicles still have low mileage. Some note that the shaking occurs at 45 miles per hour as well as at higher speeds. Others say that dealerships try to blame it on tires and wheels or tell them it’s “normal” for the vehicles.
The National Highway and Traffic Safety Administration (NHTSA) Office of Defects Investigation also has reports of the problem dating back to 2014. The complaint reproduces many of these as well.
The complaint alleges that GM knows about the defect, through consumer complaints and news reports. However, the complaint says, the company doesn’t warn customers, recall vehicles, or reimburse owners for repairs.
