General Motors 10-Speed Transmission Defect Class Action

About this case
A proposed class action filed in the U.S. District Court for the Northern District of California alleges that General Motors sold Chevrolet, GMC, and Cadillac vehicles equipped with defective 10-speed automatic transmissions despite allegedly knowing about harsh shifting, hesitation, gear engagement problems, and potential drivetrain locking. The plaintiffs assert consumer-protection and disclosure claims and seek repair costs, related damages, and changes to GM’s marketing or disclosures; the matter is in its early stages, and its current procedural stage is a new filing pending any determination on class certification.
