What 2025 GMC Terrain owners say
Electrical system
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.

Transmission & drivetrain
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.

Steering
I was driving north on [redacted] 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 crutches for my left leg, bruising and scar now from a huge abrasion to my right arm. Still having right shoulder pain. …
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. …
