I was about 45 miles or so from home on [XXX]. As I left a business my truck went about 100 feet and the engine stopped working . No warning. Truck was towed to a GM dealer in Wilmington Il. It was determined the cause was due to the wiring from the engine ECM that was run over the top of a very sharp plastic mounting bracket for the ECM. The wire had been cut because of the way this was done at the factory. In addition the fuel pump also needed to be replaced . At the time of this, the truck had 39,140 miles on it. I had no warning this was about to happen. No check engine light went on , etc. Most of my route home is on the highway . Had this not happened on a side street , I would have been involved in an accident. I ended up paying $865.42 plus towing for this repair I should not be paying for. The people at the GM dealer told me this has been happening on numerous GM pick up trucks. This is NOT a maintenance issue or an isolated case.

2020 GMC Sierra Denali – VIN [XXX] On [XXX] while driving the 2020 GMC Sierra to work I noticed a strong gasoline smell inside the cabin. I immediately returned home and parked the truck in the street. Inspecting the driveway where the truck was parked over night, I notice large gasoline spot. The following day I had the truck towed to Boyds Tire & Service center to have the truck inspected. On January 20 Boyds called me and shared the truck had experienced a failure of the High-Pressure Fuel Pump which has been recognized by GM as a recall under N192283991. I called a local GMC dealership about this failure and they stated it would cost $300 to review and would not perform any work under a recall. Also, the dealership stated they could not service the truck for another two weeks, which I cannot be without the truck that long. So, I had Boyds perform the repair the same day. Unfortunately, GM has not listed my truck on this recall. This is the reason for my submittal and request for a full refund of the repair service due to the failed part. This being a very High Risk of Fire and injury and death, I decide to have the repair completed immediately. I have since contacted GM about this incident they will not consider my request for recognizing and reimbursement for service repair.

GDI fuel pump went bad needed replacement.

13540028 Fuel Pump Power Control Module Part failed leaving me stranded and had to get a tow. When the failure occurred, vehicle would not crank and there was no forewarning. It worked and then it didn't. The part is on notional backorder and there seems to be a lot of vehicles out there with the same issue and that just with the mechanics\service departments I've contacted that have had the part on backorder for months. So the fail rate seems high and I'm sure others got stuck in a lot worse situation than me. Then GMC continues to produce vehicles with a newer similar part while not producing the same part for like new vehicles. Which will probably only compound the backorder issue when the newer vehicles eventually have the same issue.

Fuel Pump Drive Control Module (Part No. 13540028). This item is a recall on several other vehicles, but not identified on my year/model. On 4 separate occasions over a 3-4 week period, the engine starting running very rough lost power and stalled while traveling down the road (highways, interstate, and a side street). I was finally able to pull a fault code and research the history of this code and this part on several other GMC/Chevy modeled vehicles. The dealer advised I was lucky to find the part because most of them are on backorder due to the recall on other vehicles. The one I got was for a recall, but the customer hadn't returned in time so they sold it to me. I had a repair garage replace the component on Jan 13, 2024, and haven't had any repeat issues. The check engine light did come on each time with a P129F code. It would reset after the vehicle stalled and was powered off for 10-15 minutes and the symptoms would go away. Each time left me lucky to get my vehicle over several lanes and off the side of the road. The date below was the last time it happened. The first time it happened was on Dec 6th and the vehicle started back up in just a minute or two. I still have the old part if it needs to be sent and evaluated to compare with other recalls on the item in other vehicles.

Reference your GM/Chevy recall the federal safety agency [XXX] , I have a 2020 GMC truck with a failed Fuel Pump Control Module, same part/same part number used in the SUVs. Are you going to recall the trucks also. Lucky for me, mine failed as I pulled into my drive way. Had to have my truck towed to the dealership, 2 days later informed my FPCM was bad, and of course there are no replacement part available.

My vehicle suddenly did not want to start without any warning. I drove my truck and everything was good until I turned it on with the remote and not even a minute after it shut off. I tried turning it back on and it only cranked but would not start. I had a mechanic diagnose it and their computer gave them fuel pump error code. They said it was the fuel pump control module and that they have been getting several GM trucks of the same year having that issue. My truck has less than 36,000 miles on it to have this issue and I have seen that GM has issues with their fuel pump components so I dont understand why they have not recalled them. This is a safety concern because these trucks auto shut off when stopped at red lights and it could randomly shut off and not turn back on leaving someone stranded in the middle of the road without any warning.
