GM’s Transmission Troubles ContinueGM’s 10-speed automatic transmission just can’t catch a break. Back in February, the company widened an earlier recall to cover thousands more trucks and SUVs, all because of a fault that could lock up the rear wheels on the move. It’s another headache for a gearbox that’s already drawn years of complaints from owners.Now there’s a new class-action lawsuit in California. The claim? That GM kept selling vehicles with these transmissions even though it already knew about the problems. What the Lawsuit ClaimsFiled in the Northern District of California, the class-action lawsuit comes from a group of owners who say GM broke state and federal consumer protection laws by not telling buyers and lessees about the transmission issues.The complaint covers a range of Chevrolet, GMC, and Cadillac models with the 10-speed auto. Owners say the gearbox can hesitate, slam into gear, or act up without warning.The suit points out that GM has already issued service bulletins and recalls for this transmission, but the plaintiffs say those fixes didn’t solve the bigger design problem. Instead, they argue GM kept selling these vehicles while buyers stayed in the dark about the risks and possible repair bills.Right now, the lawsuit covers California owners and lessees, but these cases sometimes grow if more people step forward.2025cadillacescaladevslincolnnavigator_1600 What Happens NextSo far, GM hasn’t commented on the lawsuit. The case is still in its early stages, and it could be months before a judge decides whether it moves forward as a class action. The plaintiffs want GM to pay for repairs and other losses, and they’re also pushing for changes in how GM markets or sells vehicles with this transmission.Stepping back, when a 10-speed works, it’s great. But when problems arise, repairs get expensive fast, and owners lose trust. It’s also worth watching how Ford handles this (or if there's an oncoming lawsuit waiting), since it co-developed the transmission with GM.
