2021 GMC Acadia

Electronic dashboard failure. Entire instrument panel randomly shuts off while driving, including speedometer and all gauges. Driver then has to wait for system to reboot itself before it begins working again. This condition is completely random and may not occur for months, or may occur several times within minutes. This is a safety issue due to the driver's inability to monitor speed. It is also possible that other safety systems are being shut down while waiting for the system to reboot. GM has known about this software glitch since 2021, and it affects certain GM vehicle models from 2021-2023. (Refer to GM TSB# 21-NA-054). NHTSA should require a recall for this problem.

I have 43,000 miles on my car and I do not by any means drive hard or really ever go over 50 MPH and I am being told that my rear tow links are loose and need to be replaced. I have NEVER had to replace those in any vehicle I have ever owned especially a 2021 vehicle with under 50k miles on it. I have read that there is a recall on the 2022 Acadia's for this exact issue so I can only assume it is the same issue happening on the 2021's as well.

No matter what speed I am driving at or whether or not there is a passenger my service safety restraint system light comes on randomly and shuts off randomly. I called the dealership and they brushed it off saying it just means the airbag wont deploy if I were to get into an accident. Great thanks that makes me feel real safe! I see several people complaining about this as well and think it might be time to look into what the problem is and do a recall.

My 2021 GMC Acadia only has 25,327 miles. I purchased it new from Mossy of Picayune. The fuel pump module has been replaced 3 times. The first 2 times I was able to drive it to dealership for repairs. The last time on march 29, I was crossing a very busy highway and my vehicle just stopped without warning. It stopped as I was crossing and vehicles were coming up behind me very fast and I was almost hit. This was very scary and dangerous for me and my family and also the other vehicles on the highway . I was able to coax it into the emergency lane. I called Mossy of Picayune and was told my vehicle was no longer under warranty and they didn’t have a tow truck available. I had it towed to a local repair shop and had repaired. The cost to tow to Mossy was high (40 miles). And I paid $100.00 to have towed to local shop. The cost of repairs was $285.00. There really needs to be a recall on this dangerous situation. I have read many reviews with others having the same problem with their 2021 Acadia. I am very worried to drive my vehicle.

Vehicle engine shuts off randomly while driving, car goes into neutral, and I have to stop and try to restart it. Sometimes, the vehicle struggles to start up and requires multiple attempts before being able to drive again. The engine then misfires, the car shakes aggressively, and engine will shuts off again 1-2 more times before it will start smoothly. This is obviously a safety issue as it happens while driving and could lead to a major collision. Been to the dealership multiple times. First time, the dealership was unable to find anything wrong and could not replicate the problem. The problem continued to happen and returned to dealership where they replaced the purge valve in the fuel system. Problem started occurring again and returned to dealership. Dealership kept vehicle for a week and was unable to replicate the problem. Showed the dealership a video of the problem and they replaced the fuel pump control module. A few weeks out from the fuel pump control module replacement and the car shut off twice while driving to work.

The rear view camera was supposed to have been fixed during the safety recall in 2022, but two years later and over seven visits to dealership service repair shop, it still has not been fixed. GMC says they don't know how to fix it because they have tried everything and that because my warranty has been "out" one month - there is nothing they can do for me. My back up camera has not worked since the recall repair. What can I do? The car has been in the shop, who says they are contacting GMC Service Expert - but they are not communicating with me anymore. I have no car and no fix.
