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 to have towed to local shop. The cost of repairs was $285. 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.
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.)
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.
Car stalled on major roadway. Could not restart of shift to neutral. Car blocked traffic for 3 hours until tow. Faulty fuel control module was the cause. Car was almost hit numerous times by passing traffic.
Was driving when the vehicle engine completely lost power. Very dangerous situation in heavy traffic. Had difficulty pulling to the side of the road and ended up blocking traffic. Vehicle needed to be towed and is less than 2 years old with less than 10k miles. Diagnosis is failure of fuel pump control module. I see there is an identical GMC Acadia incident already logged by someone else and the dealer said they have seen this multiple times. After 1 week at dealer, they are unable to secure part for repair and don't know when they will. A RECALL was issued for other GMC 2021 vehicles for this exact problem. GMC RECALL N212332040: POWER CONTROL MODULE MAY CAUSE FUEL PUMP FAILURE. However this recall does not include the Acadia. The Acadia needs to be recalled as well before people are killed and the replacement parts need to be made available.
Was driving and vehicle engine dead stopped with out warning. Could not get started and had to call a wrecker to tow to GMC dealership. Were told it wasn't the first time that they had seen this. They had a part in stock to repair it. It was diagnosed as the -??drivers fuel pump module-??.was surprised that there was not a recall as this could have been a deadly incident during rush hour on the roads in my area. While researching found a recall on full size GMC 2021 SUVS from last year (NHTSA campaign number 21V739000) ! why is this not being dealt with on the 2021 Acadias? my daughter has one she bought the same day and now I am in fear it will do the same thing !!! no insurance issues or police issues. After engine died several symbols including engine icon came on when trying to restart. Also received an email -??diagnostic alert-?? from on star immediately : an issue with the engine and transmission system in your 2021 GMC Acadia has been detected. Please service your vehicle within 7 days-??.
Brand new vehicle purchased from dealer, at 8900 miles transmission slipped. Dealer has for 2 hours and couldn-??t find problem, but replaced transmission fluid it was dark. At 9000 it happened again, they have vehicle and said the new transmission fluid is dark and muddy. Only 100 miles, so they determined they need to take apart transmission and see what happened. It-??s a 52k car, it should not be repairs, it should be replaced under warranty. Video of 8900 from dealership https://video.37483.net/timeline/2CJTHEW6
