  Two problems with this vehicle: 1) Transmission occasionally slips on the 2-3 shift which the dealer says he cannot duplicate. Vehicle was brought in four times for this problem. According to the dealer GM corporate has stated the transmission is working within normal parameters, since no codes were found. 2) Vehicle auto braking randomly slams on the brakes with nothing in its path. Dealer states turn off system to just Alert only not Alert and Brake. No codes were set. Fortunately no one was behind me as this could have caused me to be rear ended by another vehicle. In both cases it appears that if no codes are set the problem does not exist. Nov. 21, 2025, Feb. 12, 2026, July 09, 2026,…

  I was driving north on [XXX] when I felt a slight pull to the right. I figured it was my lane assist even though I was in my lane. Seconds later it felt like if someone was in my passenger seat and just yanked my steering wheel to the right hitting the guardrail. My whole tire and the assembly was off but everything was still intact to the tire. The tie rods, axle, ball joints, the whole assembly. During investigation I was told by the mechanic that the stabilizer bar was a clean break. There was damage to the front end and all down the side. I was told by GM that the force of the impact was what ripped off my tire but it was not enough impact or damage to deploy the airbags. I was on…

  Car locks itself into 2 Wheel Drive when conditions are "unfavorable" meaning sometimes rain and most commonly in cold weather. If anyone has driven on snowy and icy roads during the winter, they know how much of a problem this can cause in the winter. Not only has the dealership's maintenance department not been able to diagnose the issue but GM themselves are refusing to acknowledge this problem as well. This is a huge safety hazard given the instability of the vehicle driving in those conditions, especially if you cant gain traction while on a busy road. The only indicator is the light that shows AWD and 2WD is in 2WD and an orange color. This is a big accident waiting to happen, if it…

  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…

  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…
