FUEL/PROPULSION SYSTEM
While driving 40-45 mph the engine light came on and 50% loss of power was displayed on screen. Thankfully I wasn’t far from home and was in limp mode for the last 2 miles. The mileage of vehicle is 42,000 miles. The codes are reading low fuel pressure and faulty fuel pump. Any help would be appreciated as this shouldn’t be happening to this new of a vehicle.

ENGINE, ELECTRICAL SYSTEM, FUEL/PROPULSION SYSTEM
At stop light turning right, the car stalled, cut on and cut back off, cut on and back off with about 30 cars behind me. Sputtering. On the dash board it said “Engine power reduced”. I had to be pushed out a main highway by police, and thankfully my [XXX] daughter wasn’t in the back seat. I have had this car 12 days with 48256 miles on it. I’m extremely concerned with the safety of this car. And when towed was leaking gas like fluid. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

UNKNOWN OR OTHER
The backup camera on my vehicle stopped working completely, displaying a blank screen. All other cameras and sensors continue to function normally. The dealership identified the issue as the camera having “shorted out” and is replacing it with a completely new unit. The faulty camera is currently with the dealership, and I assume it would be available for inspection upon request. It is being replaced and I will receive a bill in a few days (Wednesday March 10, 2025). The backup camera is a critical safety feature designed to prevent collisions with pedestrians, objects, and other vehicles when reversing. Without a functioning camera, visibility is significantly reduced, increasing the risk of an accident, especially in crowded parking lots or areas with low visibility. The sudden and unexplained failure of this system is a serious safety concern. Yes, the dealership confirmed the issue when I brought my vehicle in for inspection. They determined that the camera had “shorted out” and ordered a full replacement. The vehicle has been inspected by the dealership, which is handling the replacement. To my knowledge, no manufacturer representatives, police, or insurance agents have examined the issue. There were no warning lights, error messages, or other indications before the failure. The backup camera was functioning normally, then suddenly stopped working, displaying a blank screen. I have heard that Cadillac and GMC Acadia models have experienced similar backup camera issues, leading to recalls due to sudden failures. Given that my vehicle’s camera “shorted out” without warning, I believe this may be part of a broader issue affecting GM vehicles. If this is a recurring problem, it poses a serious safety risk and should be investigated further.

FUEL/PROPULSION SYSTEM
This is the second time this occurred, once in Oct 2024 and on 1/25/25. While driving the check engine light came on and within one minute the vehicle began to stall and within 20 second the engine shut off. The first time it happened in the middle of the road and the second time I was just able to turn onto a side street. In both cases the vehicle would not restart and left me stranded.

ENGINE, ELECTRICAL SYSTEM, FUEL/PROPULSION SYSTEM
I purchased the car August 2024, I have had it for 4 months and while driving down the road a large fuel tank pops up stating low fuel and the car comes to an abrupt stop.The 3x the gas tank was never low. Parking brake comes on and car doesn't not move. All lights on dash come one. It has done it 4 times and thankful each time I was in a 30 mph zone. If I was going 55 I am sure the result would have been bad. The car last did it on December 29, 2024 and has been in the dealership for 3 weeks now and they cannot fix it. I told them 3 days into my purchase I wanted a full refund and they denied me. ?? I had that right I am still fighting with them to take it back because one of these times I am going to get in a bad accident. I don't feel safe in the car and I told them each time.

STEERING
While driving, the dash warning "service power steering" light up and my steering wheel locked making me unable to steer or manuever the car to safety. I was stuck in the middle of the road. I turned it off and on and was able to make it to a parking lot where the same safety messages illuminated four more times. I tried reversing and the same steering lock occurred again making me unable to drive the vehicle.

ENGINE, FUEL/PROPULSION SYSTEM
My check engine light came on and I got it hooked up to get the code of P0171 - Upon checking it was different things like O2 sensor the Mass Airflow sensor, fuel pump issue etc. I have been having issues with slight hesitation during acceleration, some jerking when slowing down (not hitting the brakes). Now the check engine light was on for one day the next day it was off. I did some research and found an article that stated that GM is issuing a safety recall for 2021 and 2022 GMC terrain due to a problem with the fuel pump module failing, not enough fuel to the engine and creating stalling risk. This was from January of 2023. It also said GM notified the National Highway Traffic Safety Administration of the upcoming recall on Jan 19th 2023 and was still pending as of Feb 2023. Also stated that GM has not yet conducted actual repairs to correct the issue. My truck, I bought it brand new on Jan 20th 2022, only 23,450 miles on it. The problem literally came out of no where a week ago. The hesitation, not being able to accelerate is very dangerous when I'm on the road, I could not get the check engine light checked out professionally because the next day it was off and I was informed that they could not do a proper diagnostic if there is no light on. Obviously there is an issue with the fuel system and I really want this checked out and possibly replaced. Not to mention my gas is also going very fast now.

FUEL/PROPULSION SYSTEM
Fuel pump power control module failure. Part number 13554821. On [XXX], my trip home from South Carolina to Alabama was interrupted when I stopped to get something to eat. The car would not start and I had to call AAA to tow me to Superior GMC dealership in Anniston, Al. They knew what was wrong as soon as I told them it would not start. They already replaced three fuel pump control modules that day on the same model as mine. The service department said it was a persistent problem in GMC automobile's. I am [XXX] who had confidence enough in your automobile to take a trip by myself. I could have gotten stranded far away from home. I believe that this should be a recall because this is an ongoing issue with this model. I am sure that GMC is aware of this problem.
