GM class action lawsuit overview:
- Who: A group of vehicle owners are suing General Motors.
- Why: The plaintiffs allege that GM knowingly sold vehicles with defective 10-speed transmissions.
- Where: The GM class action lawsuit was filed in California federal court.
A new class action lawsuit accuses General Motors of knowingly selling vehicles with defective 10-speed transmissions.
Plaintiffs Napa Valley G Experience LLC, Juan Morales and Ruben Smith filed the class action lawsuit against GM on April 13 in California federal court, alleging violations of state and federal consumer laws.
According to the lawsuit, GM sold vehicles with defective 10-speed transmissions that can cause violent or erratic shifting, delayed acceleration and even a complete loss of motive power.
The plaintiffs allege that GM knew about the defect but failed to disclose it to consumers.
The class action lawsuit claims that the defect affects a wide range of GM vehicles, including Chevrolet, GMC and Cadillac models.
GM issued technical service bulletins and recalls related to the defect, but these measures were too little, too late to remedy the fundamentally defective nature of the 10-speed transmission, the plaintiffs contend.
Lawsuit claims GM knew about transmission defect before vehicles hit market
The plaintiffs allege that GM knew about the defect before the vehicles were sold, as the transmission was co-developed with Ford, which faced similar issues with its 10-speed transmission in its F-150 trucks.
Despite this knowledge, GM continued to sell the vehicles without disclosing the defect, the plaintiffs say.
The class action lawsuit seeks to represent a class of all California residents who purchased or leased a GM vehicle with a 10-speed transmission.
The plaintiffs are seeking damages, including the cost of repairs, as well as injunctive relief to prevent GM from continuing to sell vehicles with the defective transmission.
In a separate class action lawsuit, consumers sued GM over allegations it sold vehicles with a defective brake vacuum pump system that can increase stopping distances and impair braking performance.
