2022 GMC Acadia Electrical System Problems

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

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.

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.

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

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 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?

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
