2022 GMC ACADIA Electrical System Problems

purchased the vehicle in good faith, unaware that the check engine light was illuminated at the time of purchase and not informed that this indicated a serious mechanical or emissions-related issue. After purchase, the dealership repaired an emissions-related problem, and the check engine light was no longer present when the vehicle was returned to me. However, within three days of having the vehicle back in my possession, I began experiencing additional issues, including electrical malfunctions and abnormal noises coming from the front wheels. These problems caused the vehicle to feel unsafe to operate and raised serious concerns about its reliability and overall safety. Due to these concerns, I returned the vehicle to the dealership immediately.

The contact owns a 2022 GMC Acadia. The vehicle was recently purchased, and at the time of purchase, the check engine warning light was illuminated. The vehicle was taken to the dealer, where it was diagnosed that the emissions system had failed. The vehicle was repaired. The contact stated that on a separate occasion, three days after the vehicle was picked up from the dealer, there was an abnormal sound coming from the vehicle. The vehicle was taken to the dealer, where it was determined that the rotors and brakes had failed, and the lining for the front two wheels was damaged. In addition, the contact informed the dealer that all four windows failed to function as intended. The contact stated that the buttons to roll up or down the windows failed to operate as needed. Additionally, while depressing the brake pedal, the vehicle vibrated abnormally. The contact stated that when the radio was turned on, there was an abnormal sound coming from the radio. The vehicle remained at the dealer unrepaired. The contact was provided a loaner vehicle. The contact sent an email to the manager at the dealer regarding the vehicle. The contact was offered assistance. The following day, an employee from the dealer reached out and informed the contact that no assistance would be provided and that if the rental was not returned, it would be reported as stolen. The contact stated that she was threatened after the employee realized that she had thought about filing a Lemon Law complaint. The manufacturer was not made aware of the failure. The failure mileage was approximately 28,000.

Mileage: 28,000

I have a faulty coolant temperature sensor or thermostat in which the fan is running loudly and temperature gauge is not working

Multiple times an alert has been given for "Driver assist temporarily reduced, drive cautiously". Additionally, the check engine light has come on, with codes for the cooling system. Cooling system fan (HVAC Blower) remains on after shutting off vehicle for anywhere from 5-15 minutes. Coolant levels have been checked and are correct. Heat & AC function, however the thermostat gauge on the instrument panel does not read any temperature at all. At this time, the vehicle has not been taken to the dealership for assessment due to financial constraints.

The entire dashboard instrument panel and entertainment screens frequently go black on 2022 ACADIA. This occurs intermittently several times per week and has occurred since purchase in Nov 2024.

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.

Automatic locks are triggering while driving and soon after vehicle is parked and powered off.

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

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.

I was driving on the highway with my kids and my car suddenly shuts off. There was no warning messages or other symptoms of the problem... no signs! This took place on February 25, 2024. It was towed and taken to the GMC dealership (coral springs) for 3 weeks now.

The contact owns a 2022 GMC Acadia. The contact stated that while driving at night at an undisclosed speed, the instrument cluster light inadvertently turned on and off. Additionally, the speedometer was inoperable. The turn signal warning light was illuminated, and the headlights inadvertently illuminated on and off while driving. The vehicle was taken to the dealer on three separate occasions; however, the dealer was unable to duplicate the failure. The dealer replaced an unknown module, but the failure recurred. The vehicle was not repaired. The manufacturer was made aware of the failure. The failure mileage was unknown.

The back up camera went grainy, then completely black. The car is equipped with surround vision camera system. The camera system flashed on / off then completely blacked out. Then would randomly flash a partial picture, and then back to no picture.

Driver side blind spot monitor fails to detect vehicles. I first became aware of the problem as I was entering a freeway and nearly caused an accident. I scheduled service at my GMC dealership but had to wait two weeks for an appointment. The system stared working again just before the appointment and the dealer service department could not find a problem. My neighbor's 2021 GMC Acadia has the same issue. Does somebody have to die to correct a safety defect?
