| Service Brakes problems |
The contact owns a 2025 GMC Terrain. The contact stated that while his wife was driving approximately 40 mph on wet roads, the brake pedal was depressed, but the brake pedal was stiff, preventing the vehicle from slowing down as intended. There were several unknown warning lights illuminated during the failure. The accelerator pedal was released, and the vehicle rolled to a stop. The vehicle was turned off and restarted, but the check engine warning light remained illuminated. The vehicle was pulled over to the side of the road and turned off. The vehicle was then towed to a dealer, where it was diagnosed, and determined that the brake control module needed to be replaced. The vehicle was repaired, but the failure reoccurred approximately 7 months and 2 weeks later. The manufacturer was notified of the failure. The failure mileage was approximately 1,126.
My SUV pulls hard to the right when braking at speeds above 50 mph and much more on the interstates at 65 mph and above. I first experienced this after three weeks of ownership on a drive up I-95 on a trip to nc. It has happened numerous times while traveling on the interstates and has almost caused loss of control when having to brake hard when cut off by another driver or traffic suddenly coming to a stop. The vehicle has been to the service department numerous times. . . . At first they suspected a braking issue and have had both calipers replaced, all brake lines replaced, lower control arms replaced and the right side strut replaced. None of these repairs have solved the problem. The factory service rep who took over the situation tested 3 other GMC 2025 Terrain suvs and all had the same problem. He reported the issue on a safety report to gm in michigan and the response from gm was that it is a normal condition for the Terrain models. I have never owned, driven, or ridden in another vehicle in over 50 years of driving which performed like this, this is not a normal condition in my opinion.
