   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…

   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…

   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…

   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…

    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…
