My car suddenly out of the blue started overheating. By the time I could get stopped safely and turn the car off the engine fan kept running to try to cool it down. I’ve never had any issues with my car. It only has 47,000 miles on it. I now have to have it towed to a mechanic shop to get diagnosed, but I’m hearing that it’s probably a thermostat and that the GMC Acadia’s are famous for that being a problem. I’m not sure why GMC would not do a recall on this part! this is an extremely expensive fix.
Getting a pop up that says “steering assist reduced”. Temp gauge drops completely. AC won’t work and fan kicks on
"STEERING ASSIST REDUCED. DRIVE WITH CARE" message, fan runs nonstop, even after the vehicle is off. Sounds like a plane taking off. This seems to be EXTREMELY common after doing my research. Please consider turning this into a recall!
Recently took vehicle for alignment for a pull to the right. After 3 alignments at the dealership I was told the rack and pinion gear sensor shorted out causing the vehicle to pull to the right.

Recently took vehicle for alignment for a pull to the right. After 3 alignments at the dealership I was told the rack and pinion gear sensor shorted out causing the vehicle to pull to the right. Also the exhaust has a rattle in the resonator confirmed by 2 sources. I asked the dealer to fix years ago under bumper to bumper and tsb PIT5863. I was told not enough techs and not enough time so now the warranty is expired and the issue isn't fixed.
I have a 2021 GMC Acadia that keeps saying steering assist not available. But when it does this, the temperature gage stops working and so does the AC. After you turn the car off the fan still runs for at least 10 minutes.
The Vacuum pump on my 2021 GMC Acadia failed causing my breaks malfunction. This Problem was confirmed by a certified mechanic that repaired it. this is in conjunction with the NHTSA recall issued under N192268490.
On numerous occasions the key fob is not detected and locked out of vehicle. Key fob notice on panel saying it’s not detected while driving. Took it to Jim Causley GMC dealer several times and then they kept vehicle for a week unable to duplicate and sent me on my way. This is still happening with no help.
While driving all displays, gauges, screens shut off. Unable to determine speed or anything. Car still drives but there is zero driver feedback. System will come back on and the it will happen again. Has been going on for 2 years. Dealer unable to determine the issue.

1PE22006 · Rear-View Camera Failure
Opened Jul 22, 2022 · Closed Nov 21, 2022
Status: closed (inferred from source dates) · Back Over Prevention: Sensing System: Camera
On July 22, 2022, the Office of Defects Investigation (ODI) opened a Preliminary Evaluation (PE22-006) to assess alleged failures of the rear-view camera (RVC) in Model Year (MY) 2020-2021 Cadillac XT5, XT6, and GMC Acadia vehicles. The complaints report that the screen for the RVC is black, sometimes with a red triangle and a circle with a line through it. To date, ODI has received a total of 18 complaints and several EWR Field Reports with allegations of the RVC image failing to display when the vehicle is in reverse. The reports have been received over the past 28 months with most occurring with low vehicle mileage.During the investigation, ODI learned incorrect crimping specifications were utilized in the production of the coaxial cable connector. Improper crimping leads to loss of connection between the RVC and dashboard screen that results in failure of the RVC image to display. Failure or malfunction of the RVC image to display results in reduced visibility of the area behind the vehicle. This limited view may lead to an increased risk of incidents resulting in injury and/or property damage while the vehicle is in reverse.The improperly crimped connectors were only present on subject vehicles equipped with the optional RVC surround vision feature (UV2). Vehicles not equipped with the optional RVC surround vision feature were not affected by this failure. On September 28, 2022, General Motors (GM) filed a defect information report (NHTSA number 22V-709) recalling certain MY2020-2021 Cadillac XT5, XT6, and GMC Acadia vehicles equipped with the optional RVC surround vision feature (UV2). GM will replace the coaxial cables with properly crimped connectors.In view of the recall action being taken by GM, ODI is closing this preliminary evaluation. NHTSA reserves the right to take additional action if warranted by future circumstances. The ODI complaints cited above can be viewed at www.nhtsa.gov.
