General Motors Faces Lawsuit Over Alleged Brake Failure in 2025 SUVs and Trucks
A growing number of General Motors (GM) owners are speaking out against the automaker, claiming that their brand-new SUVs and trucks have a serious safety flaw. The issue at the center of the controversy is alleged brake failure in certain 2025 models.
Vehicles Affected
The lawsuit, filed in the U.S. District Court for the Eastern District of Pennsylvania, covers owners of the following vehicles:
- Chevrolet Traverse
- GMC Acadia
- Buick Enclave
- Chevrolet Colorado
- GMC Canyon
Alleged Defect
Plaintiffs claim that the master cylinders in these vehicles can fail, causing sudden brake failure. This can result in warning lights and messages on the dashboard, such as “Brake,” “Service Brake System,” and “ABS Fault.” Some owners have reported that the brake pedal feels stiff or sinks to the floor.
Lack of Response from GM
Despite the allegations, GM has yet to issue a recall or formal response to the lawsuit. Two Traverse owners claimed that their master cylinders failed while driving, and although GM replaced the components under warranty, the plaintiffs argue that the automaker failed to fix the issue within a reasonable time.
Real-World Evidence
The National Highway Traffic Safety Administration (NHTSA) website contains numerous complaints from owners who have experienced similar issues. One owner of a 2025 GMC Acadia Denali reported multiple brake warnings and a long stay at the dealership, where the issue was attributed to a faulty master cylinder assembly.
Owner’s Account
The owner’s complaint reads: “While driving my 2025 GMC Acadia Denali… I received a ‘Service Brake Assist’ warning lamp as well as ‘Check Engine’ and ‘ABS’ warning lamps… The dealership identified the issue as EBCM and master cylinder assembly failure. It replaced the EBCM and master cylinder assembly, test drove the car 7 miles, and told me my Acadia was ready to go. I did not make it out of the dealership parking lot before the ‘Service Brake Assist’ and ‘Check Engine’ lights came on again.”
Waiting for Answers
As of now, GM has not issued a recall or commented on the lawsuit. The plaintiffs claim that the automaker sold vehicles with allegedly faulty equipment, choosing not to notify customers about the risk.
