2022 GMC Acadia Complaints

ELECTRICAL SYSTEM,VISIBILITY/WIPER — Filed 08/10/2026

What failed & is it available? The infotainment/radio module failed entirely due to an OTA software update (Codes: U18B4, U0184, B1325). The vehicle and component are fully available for inspection upon request. How was safety at risk? The federally mandated backup camera is now too faint/dim to read, destroying rearview visibility. Bluetooth/hands-free phone pairing is completely disabled, increasing driver distraction risks and preventing compliance with hands-free driving laws. Is it confirmed by a dealer? Yes. A local GMC dealership inspected the vehicle and confirmed the module is bricked, quoting $2,286.00 for a hardware replacement. Inspected by manufacturer/others? It has been inspected and confirmed by the local GMC dealer network, but GM corporate has refused to physically inspect or resolve it. Prior symptoms? No prior warning lamps or symptoms occurred. The system functioned perfectly until it instantly crashed during the remote update on August 10, 2026, at 9:00 PM.

AIR BAGS,SEAT BELTS — Filed 08/15/2026

Since we purchased our 2022 Acadia 6/24/2022 we have had the warning "Service Safety Restraint System" pop up randomly. We have mentioned it numerous times over the years when the vehicle has been in for routine service at our local dealership. They have never been able to determine the cause as no service code ever shows up for them. Today in addition to the warning the red air bag warning light also lit up briefly. The warning has popped up 2x in the last 2 weeks again with today being the only time we noticed the red light as well. We are now more concerned about the safety of our vehicle. (We will be on vacation now through 8/25 & would be available after that date for any contact)

“Steering Assist is Reduced” warning, P0128 code, thermostat-related symptoms, increased steering effort or other safety concerns while driving. This issue required increased steering effort and affected my wife's driving ability to respond to changing traffic conditions. This is most likely a faulty thermostat housing assembly. This has been well documented temperature gauge problems, cooling system issues, and related warning messages. Our GMC Acadia is a 2022 AT4 with 53,500 miles. GM recently issued Special Coverage N252508350 for 2021 Acadias with the 3.6L LGX engine affected by thermostat housing issues. Owners of other model years reporting substantially similar symptoms remain responsible for the repair cost. Please investigate this.

POWER TRAIN,ELECTRICAL SYSTEM — Filed 05/01/2024

This vehicle was bought brand new and has received proper maintenance from one dealership since purchasing. I had to replace the thermostat and radiator before owning the vehicle three years. Within two years of owning the vehicle, my battery went out, which I thought seemed a little early. Then shortly after, I noticed that my locks weren’t engaging when I took my car out of park. Then my car wouldn’t even lock. When I tried to do it on the door control, nothing happened, then when I used my key to do it, it caused the alarm to go off and I couldn’t get it to stop. This resolved after a day, and then it rained again, and it started again. This time, my car wouldn’t unlock and I was trapped in my vehicle and had to open the trunk to get out. This is a known issue according to GMC with no fix. I took it to the dealer, and the codes were saying BCM and told it was being replaced but instead was “serviced”. This issue has begun again, and now I’m being told the locks are the issue and not the BCM, and that may not be covered under warranty. Not being able to get out of your vehicle or not being able to lock your car is a safety issue for passengers leaving them vulnerable to theft, someone entering their car while they’re in it and hurting them. I have had so many issues out of this vehicle and I do not believe I should have to pay for a repair that is a safety issue KNOWN TO THE COMPANY. I feel unsafe driving this vehicle now and it doesn’t even have 60k on it. So I’ve estimated on the date of the first incident and the new one just Happened this week. The information about this issue can be obtained from my dealership and GMC as it is a known issue with no real fix.

ELECTRICAL SYSTEM,SERVICE BRAKES,ENGINE — Filed 11/24/2025

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.

UNKNOWN OR OTHER — Filed 11/07/2025

Vehicle has an ongoing water leak, has been to the dealer twice so far. Both times said it was fixed.

UNKNOWN OR OTHER — Filed 11/10/2025

No specific incident. High pitch rattling in ceiling. Does not seem to be coming from the sunroof but the middle light fixture.

UNKNOWN OR OTHER — Filed 10/01/2025

The rear view camera fails to function intermittently and is occurring at a higher rate of frequency. On numerous occasions when the vehicle is put in reverse the screen goes black with a red triangle caution symbol and a white camera crossed out. Now the system is unavailable more then operational. Based on the drivers rear vision when backing in this particular vehicle, the lack of the rear camera view increases the risk of crash. This also increases the risk of severe injury to a pedestrian behind the vehicle. The same issues were addressed on earlier models via a safety recall which should be extended to 2023 model.

UNKNOWN OR OTHER — Filed 10/23/2025

Message with “steering assist reduced, drive with care” pops up on the screen. The temperature gauge drops to on the cold side. After you shut off the car the fan will run for 10 minutes trying to “cool” the car. The temperature cannot regulate.

ELECTRICAL SYSTEM — Filed 11/27/2025

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

STEERING,ENGINE,LANE DEPARTURE — Filed 11/21/2025

The “Steering assist reduced” message came on and, when shut off, the fan blows very hard and loud.

UNKNOWN OR OTHER — Filed 11/21/2025

Coolant temperature gauge stops working and shows cold temperature reading. The radiator fan runs for about 2 minutes as if the engine is overheating. I think it's a temperature sensor issue or thermostat issue or both.

ELECTRICAL SYSTEM,ENGINE — Filed 11/23/2025

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.

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

UNKNOWN OR OTHER — Filed 05/15/2025

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!
