2022 GMC Acadia

I have had multiple sensor issues with my Acadia since reaching 60000 miles. Currently, there is a thermostat sensor causing hard shifting, No cold air blowing from the AC, stabilitrack, traction control, steering assist reduced and fan running after turning off. I would not report it but I am in a facebook group where MULTIPLE people are reporting having the same issue in their Acadia's.

The contact owns a 2022 GMC Acadia. The contact stated while driving 5 MPH, there was an abnormal clunking sound coming from the rear of the vehicle. There was a squeaking and squealing sound coming from the rear of the vehicle. There were no warning lights illuminated. The local dealer was contacted, and an appointment was scheduled. The vehicle was not yet diagnosed or repaired. The manufacturer was contacted and referred the contact to the NHTSA Hotline for assistance. The approximate failure mileage was 56,000.

The Fuel Pump Control Module failed. It happened when the car was parked. The car would crank, but would not start. We were stranded far from where we live. It was hot and we had to be towed to a GM Dealership. This part could have failed on the hi-way with awful results. The Dealership verified the defective part. We have the old part as needed. Lots of lights flashed and went out. The Engine Light stayed on. The Gas Gauge was not reporting the correct amount of gas in the tank, but seemed to correct itself before the part failed..

My 2022 Acadia does not go into park at times even though the control button shows that it is in park. On May 15, 2025, I pulled under my carport and put the car in park. As I reached for my purse in the passenger seat, the car started moving forward even though it was in park. It ran through my privacy fence and injured my daughter who happened to be on the other side of the fence. She had some pretty severe bruising and scrapes on her hip, thigh, and upper body. The pain is bad enough, but her arm and shoulder was injured. It continually feels like something running up and down her arm. This is three weeks later and she still has the problem. The horrifying fact is the reality that I could have killed her through no fault of my own. I had the car towed to the dealership because I was afraid to drive it. Of course, the service department said they ran a test through the electrical system and found no problem with it. They brought my car to the front and told me there was nothing wrong with it. In fact they said they had not heard of that kind of problem. When I have to park I find a parking spot that would be least likely to have someone walk in front of it. If I have to park facing anything I will not pull up fully into the parking space so if my possessed car decided to go for a joy ride while in park again, at least someone would have a running chance to stay alive. I consulted the internet trying to find a fix to the problem. What I found was that GM has had the problem for years and has no idea how to fix it, yet they are allowed to continue to sell vehicles that are a potential safety hazard to society. My vehicle is a safety hazard to me and to society. Also learned that if you take you car to the repair shop you are appeased thinking they repaired the problem and yet it continues. When your warranty runs out, GM expects you to pay for any further visits to the shop. As far as I'm concerned selling GM products could be considered A FRAUDULENT ACTIVITY!

My Acadia has had a stuttering problem and we have taken it to the dealership many times. They finally changed the torque converter but that didn’t fix it. Now today (4/15/25) I got home and I was getting a steering assist reduced error code and then when I turned my car off the fan went as high as it could and wouldn’t turn off. Finally after a bit of time it turned off. I got my car 4/28/22

12/13/2024: While pulling onto the highway, the vehicle suddenly not accelerate past about 18 mph and would not shift gears, only rev the engine louder. Once button was pressed to engage shifting gears manually, the gear number was not shown on the dash as usual, only the letter L. We were able to drive slowly to the next exit ramp to get safely off the road. Notification about engine/transmission popped up on dash and on myGMC app. On star emailed report. Vehicle was towed to local GM dealer and assessed. Have been told that transmission needs completely rebuilt, but no description of actual issue. As of today, 2/5/2025, still waiting on parts to complete transmission rebuild.

While deiving in three lanes of traffic in rainy weather. The vehicle began to buck as though the engine was cutting on and off. No warming lights or abnormal noises preceded the event. The vehicle lost traction several times, but recovered. As quickly as it happened it stopped and normal driving resumed. It occurred 2 more times after approximately 1 mile of travel. I was able to limp the vehicle home, but once I shut it off it would not start again. I had it towed to the dealership and the service consultant informed me that it was the Fuel Pump Control Module that had failed and it was covered under warranty.

This is on behalf of my mother who doesn’t speak English only Spanish and has been having issues with this car The radiator fan stopped working on my moms car causing engine to heat up and almost blow up in the middle of the road and I had to pull aside. Had to also replace original battery in middle of a red stop light car turned off and never came back on due to faulty battery is what the auto parts told me when they tested the battery out. Back up camera never turned back on went completely black Left mirror for signaling also went black. Cause for me not to be able to see other cars coming from other lanes.
