While driving at approximately 55 mph, the vehicle suddenly stalled and would not accelerate. I was able to pull over onto the shoulder and turn the vehicle off. The engine would not turn over and the brake pedal locked into position, rendering the vehicle immobile. The check engine light also came on at this point. The vehicle was towed and ultimately repaired at the local GMC dealership, where the fuel pump was replaced. The 2022 GMC Terrain already has a recall in place due to the fuel pump module not providing sufficient fuel to the engine, resulting in an engine stall (23V013000), the effects of which sound very similar to what occurred. However, this vehicle’s VIN was not included in the recall. We are very lucky that this failure did not result in a crash, and that no further incident occurred while we were stranded on the side of the highway during the night, waiting for a tow.

The infotainment center has a tendency to freeze upon starting the car. Subsequently, when the car is put in reverse the back up camera will remain on for several minutes after putting the car back into drive causing a distraction to the driver. The freezing of the infotainment screen will often stay frozen even after turning the car off. When the car is off and the door is closed and locked, the screen stays on and music stays blasting, unable to turn the music down or off even though the car is off and locked with no one inside. The screen has stayed on for over an hour and upon returning to the vehicle, the car took several tries to start. I can only assume that the freezing is beginning to cause the battery to drain. This is causing a safety concern as loud blaring music is distracting and the possibility of being stranded without being able to start my car is a scary thought. This problem has been occurring since I purchased the car and has not been able to be reproduced by the dealer as it only happens randomly a few times a month.

April of 2022 I purchased this car brand new. January of 2023 this car started to have a musty/mold smell. I took it into the dealership in late February and inquired if this was a reported problem. I did as they dealership said and replaced the cabin filter. The cabin filter was black at 9,700 miles. It smelled horrible. On April 6, 2023, I took my car into the dealership to resolve this smell. It was discovered that the the cowl inside the firewall on the drivers side firewall had several holes and an incorrectly applied seam. It was also discovered that the drivers side sunroof drain was also disconnected. This was was full of mold. They replaced the entire interior of my car which took until June 28th. I expressed I did not want this car back for fear of mold, I had already been sick and had no idea why. Once I got into a dealer car, I quit coughing. The dealership cannot guarantee me that they got all of the mold in the car, it still has an odor in it. I have went through the claims process with GM and they have refused to buy back my car, based on my claim I am worried about my health. This car had $12,000 in repairs to it. I was promised verbally by the District Manager of After Market Sales that my car would be bought back. They backed out on the deal and told me they cannot buy it back for destruction. I have great concerns about my cars safety with the mold being so large. They cannot guarantee me the mold is completely gone as told me to by the Service Manager. Therefore, this would include the safety of others that travel in my car, to include children and older adults. This problem started in manufacturing and was acknowledged by the dealership as such. It was a defective car when it arrived on the lot.
