ELECTRICAL SYSTEM
While driving down the interstate at 70mph+, the instrument panel went black and restarted multiple times. The car continued to stay at a sustained speed, but I was unable to control anything or see how fast I was going. It appears as if the car has shut off, but it isn't. It also affects the lights. It has happened multiple times with no known cause. When I brought this up at the dealership, they said that it would be an $80 diagnostic fee and unless they can replicate the problem they can't do anything about it because it doesn't throw any error codes. There was another women in the dealership the same time as me with the exact same issue. No fix offered. Looking online and talking to others this seems like a common issue that GMC is ignoring.

ENGINE
Engine exhaust makes vibrating noise similar to a leaf blower under acceleration. TSB issued due to common issue and GM refuses to recall or fix. Broken baffle/weld inside of front muffler/resonator on exhaust system under front passenger compartment. Issue getting worse. $2500 at local dealership to fix, with GM offering “assistance” to fix issue in the amount of $742 leaving the consumer with balance. At what point will the rest of the defective part deteriorate and cause clogging issues and more damage?

ENGINE
Vehicle stalled out and instrument panel showed no gas when the tank was over half full. I had trouble re-starting but was able to only drive a mile before stalling again. Both times occurred at a stoplight I had it towed to local dealer . They replaced the fuel pump power control module. The service personnel said that they see a large number of these and that some people had accidents due to this. I was about to enter a very busy highway at rush hour and if this happened on the highway, it would be very dangerous. I saw that there were previous recalls on GMC/Chevy vehicles similar to mine from 2021 that had recalls for this same reason but the Acadia has not been included. From what I have seen, a recall should be considered.

ELECTRICAL SYSTEM
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.

SUSPENSION
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.

AIR BAGS
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.

FUEL/PROPULSION SYSTEM
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.

FUEL/PROPULSION SYSTEM
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.

BACK OVER PREVENTION: REARVIEW SYSTEM BRAKING
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.

FUEL/PROPULSION SYSTEM
FUEL PUMP CONTROL MODULE The fuel pump control module failed while sitting idle at a major highway intersection during the noon rush hour. All efforts to remove from the highway failed because the electronic shifter could not be moved to the neutral position and the electronic parking brake could not be disengaged. It was two hours before a tow truck arrived and traffic was backed up for approximately one mile. The vehicle was towed into the dealership where the problem was identified and the fuel pump control module was replaced. (Invoice attached.) I am unaware of any accidents related to this specific incident, however given that traffic was backed up as far as it was, it is certainly a possibility. The component was not inspected by anyone other than the dealership. There were no warnings, indicators, or symptoms prior to the failure. The same component (FUEL PUMP CONTROL MODULE) failed again more recently. Fortunately it occurred in a shopping mall parking lot and only caused inconvenience and delays. However, there is evidently an issues with this particular component. (Invoice included to verify part failure and replacement.)

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.
