2021 GMC ACADIA Complaints

Airbag light on dash comes on solid. Dealership had vehicle for 3 days and repair made to seat belt tensioner, days later, airbag light returns on dash. Other GM vehicles were recalled for airbag problems but maybe should include the Acadia.

The exhaust resonator failed only a few hundred miles after warranty (60,300) and not covered by dealer under warranty. It creates a noise and reduces power/performance, which could inherently create a safety concern. The vehicle was inspected by an independent service center. The following code for the rattle noise is PIT5863.

Service safety restraint system notice comes on constantly and disappears at random times.

The fabric on my headliner/ceiling is coming unglued or the clips are not holding it. It is a danger to my driving the car as it is continually loosening; which could potentially fall while I am driving the car. It is making an irritating squeaking noise which distracts my concentration from driving carefully. I took the car to Walker GMC in Alexandria, Louisiana. The mechanic and the service advisor both told me GMC has issued an instruction form on how to fix this problem as GMC has had complaints with this happening to the Acadias. I contacted GMC customer service. They will not let me know if they will cover the cost of the repair until I get an estimate. Walker is wanting to charge approximately $188 for the estimate. Since this is a safety issue, I am reporting this problem to your agency so that others may be protected and GMC will take care of this problem.

The contact owns a 2021 GMC Acadia. The contact stated that while reversing, the back-over prevention camera failed to display an image. The vehicle was taken to the local dealer who diagnosed that the back-over prevention camera was faulty and needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure and informed the contact that the VIN was not included in NHTSA Campaign Number: 22V709000 (Back Over Prevention). The contact stated that the vehicle had experienced the failure listed in the recall. The failure mileage was 25,000.

Vehicle lost power and died during normal driving. Luckily it occurred on a low traffic road and not the interstate. Prior to this there were no check engine lights or other signs of failure or degradation in performance. Was unable to start the vehicle and had to have it towed to my local dealership for service. Failure was due to the Fuel System Control Module GM part 13543075. This part is currently back ordered nation wide and the dealership cannot give an ETA on part availability or repairs.

The car stopped working all of a sudden, I was driving the car with no issues that morning and parked & shut off car to go to my appt. I turned the car back on and worked fine as I was putting in my address on the GPS my car just stopped and shut off by itself. I pushed the start button and it sounded like it wanted to start but it wouldn't and the whole engine shooked. Called GM and car still under warranty had it towed to the nearest GM. They diagnosed it and said it was the fuel injector module that went bad. It's 2021 with only 23800 miles. After a week, just got it back for a day and now the cooling fan has a loud noise, check engine light on, coolant stays on C even after driving it more than 10 mins, ac blows hot air, I get an alert with steering assist is reduced and to drive with care.....seems like something is wrong with the thermostat.

My grandson used the safety restraint in the middle second row seat. He pulled the belt out to put it on and it would not retract. I have taken it to the dealership to have it fixed but there is a fee of $515 to fix it. I do not feel I should have to pay the since it seems to be an ongoing problem with the Acadia model. I purchased a 2018 model before this one and the same thing happened with the middle safety restraint in the second row seat. I have contacted GM and they informed me there is nothing they can do to waive the fee of fixing this defect.

The contact owns a 2021 GMC Acadia. The contact stated that the software update was performed under NHTSA Campaign Number: 22V709000 (Back Over Prevention). After the software was updated, the Lane Departure Assist system failed and was no longer alerting the driver when the vehicle was drifting into the other lane. The vehicle was taken back to the dealer who completed the software update however, the cause of the failure was undetermined. The vehicle had not been repaired. The manufacturer was made aware of the failure. The approximate failure mileage was 17,700.

My 2021 Acadia digital dash goes out (completely black). I took it to the dealership on Friday August 25, as the issue was happening more frequently. I was told the software was not current. This was attributed to parking in a garage each night. Yesterday September 22 while driving, the dash again went out for a much longer timeframe (several miles). I called the dealership. Service was closing but was told by the receptionist that one of the sale people said to (1) park the car, (2) turn off the engine, (3) open the drivers door and leave open for 5 minutes to reset the system and everything should be fine. The black dash prevents the driver from seeing current MPH. I am uncertain if it also disengages adaptive cruise control and auto-braking. Is it acceptable for the digital dash to routinely go black while being operated? Is there a more sustainable resolution for the dash going out? Thank you!
