2025 GMC TERRAIN

Vehicle did not go into park when the ignition was turned off. Car started to roll while passenger was getting out of the vehicle as another vehicle was parking beside us. The other vehicle could not avoid our rolling vehicle. Passenger had to quickly sit down to avoid being hit. The next day the vehicle was taken to the dealership, and they could not find anything wrong. They gave us a copy of bulletin#08-07-30-026I. We were not aware of any problems or bulletins being issued prior to the accident. We had repairs of $2,705.71 and don't know what the other driver incurred.

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.

I just purchased a brand new 2025 Terrain. The entire windshield is defective. The glass is distorted and causing visual impairment. It is VERY unsafe. I have contacted the dealership multiple times and have not yet received a response.

Incident 1: Pulled out from stop sign car made funny noises, light came on said it couldn't shift to drive. Had towed to dealer. They said couldn't find issue except it was quart and a half low of transmission fluid. The car had approx 3,500 miles on it. Incident 2: For about two weeks when pulling out felt like it was skipping but didn't feel like transmission. Felt like over powered. Then it done same as Incident 1. Pulled out made noise would not move. Notice that is couldn't shift and check engine light came on had it towed again. Approx 6,300 miles on it. They then said it was very low on transmission fluid and they did find a small hole in hose. Danger is pulling out and it just stops in cross traffic and won't move could easily be hit. It is very scary to drive not knowing if or when it is going to happen. I have no current invoice on vehicle as it is still in shop.
