2021 GMC Acadia fuel/propulsion system problems

“exhaust flex pipe is cracked. Causes fumes of gas to be released through the crack. inspected by GMC Repair shop Vibrating noise started, then a few days later the smell of gas, and now yes the Engine light is on. This has been on going for about 3 weeks.”

“My 2021 GMC Acadia that has 63,768 miles on it was idling Wednesday 9/30 when it died and would not start back we had to have it towed to a shop to get it checked out and it was throwing the P023F code for the fuel pump control module that has a recall bulletin for the same thing make model problem and under their 80,000 miles but recall not on my vin number and GM is refusing to pay for it. It's going to cost me 937.27 to get it fixed.”

“While driving home from work the car displayed a "No Fuel" warning, despite having a full tank of gas. Within seconds of the display showing the car stalled out and stopped right in the middle of the road. It would not go into neutral and I had to be towed from the middle of the road to a mechanic close by. Upon reading forums online it looks like this is a known and common issue affecting the fuel pump sensor and system in these models. There are no open recalls but being this is known and happens so often I am shocked GMC has not taken ownership to recall and correct this issue. If I had not been on a slower road I could have gotten into an accident and, as I said, the car would not go in neutral so I couldn't even safely get off the road.”

“I have seen numerous complaints for this same issue. My 2021 Acadia with 31,600 miles failed to start when parked in garage. It turned over just fine but wouldn't fire as if it wasn't getting any fuel. I had it towed to my regular mechanic. He troubleshot it and told me it was the "Fuel Pump Power Control Module". He said he could replace it but it would have to be programmed by a GM dealer as he didn't have the equipment to do that. So I had it towed to the local GMC dealer. Two tow bills equal $360. There is a recall for this issue. It is called "Emission Recall N252516900, Fuel Pump Power Control Module". part number 13554820 I have yet to receive a recall notice. I have seen mentioned in several of the other complaints that I have read that many of the service employees say that this has been an ongoing issue for several of the GM vehicles. Hopefully I will get a recall notice soon and be able to get reimbursed for the cost of the repair.”

“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!!!!!”
