General Motors is facing a new class-action lawsuit over claims the automaker shipped vehicles with faulty eight-speed automatic transmissions.
This class-action suit was filed against GM in the U.S. District Court for the Eastern District of Michigan, Southern Division. According to Car Complaints, the plaintiffs say the GM eight-speed automatic transmissions in certain vehicles “slip, buck, kick, jerk, harshly engage, suffer abnormal internal wear, sudden acceleration, delay in downshifts, delayed acceleration, difficulty stopping the vehicle, and eventually require replacement of the transmission or its components.” These problems are allegedly traced back to an issue with the torque converter that causes excess friction.
The lawsuit also cites more than 60 technical service bulletins and service updates put out by GM regarding the eight-speed transmission problems, saying these documents are evidence GM was aware of problems with the transmission and decided to sell the affected vehicles anyway. Separately, C7 Corvette owner complaint submitted to Car Complaints back in 2015 stated they were told by a “GM insider” that the automaker was ” aware some transmissions are defective and is working on a kit to fix the fluid starvation problem internally,” which is allegedly the reasoning for the shuddering/jerking transmissions.
Numerous class-action suits have been filed against GM over its 8L45E and 8L90 eight-speed automatic transmissions in recent years. The automaker sought to have one of these suits thrown out last August, claiming the transmission problems are related to a design defect and not a manufacturing defect. GM’s vehicle warranties only cover manufacturing defects with parts and components and not design defects. Most of these suits claim all vehicles with these eight-speed transmissions are defective, which would imply a design defect and not a manufacturing defect.
This latest class-action suit calls on GM to reform its warranties to address these transmission problems and also issue a recall for affected vehicles.
