2021 GMC ACADIA Fuel/propulsion System Problems

My Acadia, 2021 has just 36011 miles. Car sputtered a few times like it was running out of gas and stalled as I was driving home in rush hour traffic. I couldn't even get it off the road. No warning lights or advance warning. Waited 3 hours for AAA (told 20 minutes) and then towed to dealer. Tow person could not get it into neutral so they used the sleds to ramp it up onto the flatbed. The dealer replaced the fuel module board which seems to be a common problem with these cars. Dangerous in that I thought someone might rear end the car while sitting in the single lane. Look on the Acadia forum and you'll see this is common and no recall has been issued and it sounds like it could very well happen again.

I was driving down a heavy traffic expressway with a lot of semi traffic and the SUV started puttering. All of a sudden it died, the check engine light came on and I started to slow down quickly. I was in the middle lane of 3 lanes going 70 mph. VERY LUCKILY, I was able to pull to the right and barely made it onto the shoulder. The SUV had $28,972 miles on it. It was more that 100 degrees outside at the time. I called for a tow and had to wait over 2 hours. My car was nearly hit many times during the wait. The whole situation was very dangerous. What if my children were in the car at the time???? The tow truck driver was nearly killed while trying to get it on the truck. He had to call the police to block the lane. He stated that he could not put it in neutral and had to do something else with it to get it up. It was towed to the dealership where I purchased it. They did the diagnostics and said it was a fuel pump module issue. Less than 30,000 miles and this happened. I was planning to take a trip through the mountains, but at this point I do not feel safe at all in this vehicle. THIS SHOULD BE A RECALL IF GMC IS AWARE OF THIS ISSUE!!!!!

Car was parked overnight in my garage and in the morning it would turn over, but not start. Had to have it towed to my GMC dealer, but had great difficulty moving the car out of the garage because the transmission remains in PARK if the engine is not running. Had this happened on a highway while driving and without a place to safely get off the road ( which HAS happened to others who have made this same complaint to NHTSA), this could have been an extremely hazardous situation for the occupants of the vehicle. The engine will suddenly shut down, power steering is lost, and power braking will also be lost. This problem was diagnosed as a failed fuel pump module. The failed part was replaced by the dealer (GM part#13554820). The service manager acknowledged that this is a known and common issue and that GM is aware of it but has not issued a voluntary recall. The manager also advised that this part has not been updated and that it may fail again without warning. Please....this is a serious safety issue that needs to be addressed before someone is injured or killed while abandoning a car stalled in traffic that cannot be moved.

Driving on rt 95n in Ga. Going 70 mph and vehicle just bucked and shut off. At the time I was in the middle lane and almost got hit by a tractor trailer while I was trying to get to the right side of the road. Called general motors roadside assistance and they supplied a tow company to tow me to a dealer in Ga. About 35 miles away unfortunately it was Sunday dealer was closed and I had to get a taxi to take me to a hotel with all my luggage. On Monday morning when the service dept. Opened they advised me the fuel pump module had failed and would be replaced. Luckily most times when vehicles shut off with push button electronically shifted transmissions you can't put the vehicle in neutral to move or tow but after many tries it went to neutral(according to the tow driver) also after researching my vehicles failure I found this is a wide spread problem among many gm suvs and trucks! Hopefully a recall is in the future before someone gets killed!!

Car stalled at intersection and unable to restart. The car would not go into neutral to get the car out of the roadway. The fuel pump driver or fuel pump fail with 41k miles. The condition is very unsafe.

May 2023 we took the car to the GM dealership for a electronic recall. We reported a rattling noise at that point in time. Whatever repair was done that the car ran w/o any noise for nearly a year. April 2024 the catalytic converter failed at just 61K miles on this vehicle. The mechanic at the same dealership noted a broken mounting bracket and replaced the catalytic converter. October 24 2024 at 76K miles the car started making the same noise. The mechanic at the same dealership noted a loose mounting bracket due to an excessively vibrating catalytic converter, a crack on the cat converter, a leak and sequentially damaged front pipe. They noted they made all of those repairs. They noted they test drove the vehicle and verified the car was repaired. October 26, 2024 after those final repairs the car made a loud revving noise and emitted a smell of sulfur. The next day the car died on the road while driving. Every system of he vehicle shut down and I narrowly avoided getting hit from behind. On 11/2/24 We had the car towed to the dealership again. The mechanic noted the recent replacement on the cat converter & oil had leaked intermixing. That caused the motor to seize and the car to stop working while I was on the road driving. I can't imagine what could've happened to me had it stop on the highway at 65mph.

While driving, the vehicle shut off without warning. It was in-traffic when this occurred and subsequently blocked traffic. I tried to restart the vehicle many times. It would start and then die within a few seconds. Since the vehicle would not remain running, it was impossible to shift out of the "park" position. Since it was in "park", the vehicle could not be readily moved out of traffic. This failure is a safety hazard! The vehicle was towed from the scene. The dealer diagnosed the problem as the "Powertrain control module lost communication the the fuel pump driver module causing no fueling to engine from low pressure fuel pump U18A..." The fuel pump control module had internal communication circuit failure. GMC module 13554820 was replaced.

Vehicle stalled on major interstate while giving no warning Vehicle would not start after failure Had to be towed to dealership Found to be a faulty fuel pump module Service advisor even said this is a common problem Vehicle mileage was at 33,478 This could have been a deadly accident

46,000 miles on my car. Fuel management system failed. Would not start until we unplugged battery, and let it reset. Car lost acceleration and went into neutral on highway.

5 September went to start my car and the car started before i put it in drive it stalled and i could not restart the car kept turning over and will not run. plug in a diagnostics machine and found fault code P023F Fuel pump control module. this was the same fault I had two years ago june 2022. replaced the unit but part number has changed "13543075 has changed to a new number of 13554820" so GMC is aware there is a problem with the old part. included an image of original repair.

Vehicle shut off on highway, was able to pull off on shoulder. Would turn but not start. Dealer states fuel pump control module fault.

The vehicle, without any warning, suddenly stopped. I was unable to restart and unable to put the vehicle in Neutral for pushing to a safer location. Had to be towed to the dealership.

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.

UNKNOWN-THE VECHILE WILL NOT START AND SHOWS THE FUEL IS EMPTY, BUT I JUST LOOKED PRIOR AND HAD 3/4 FULL.

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
