My vehicle fuel pump control module has failed. GMC has an open recall for my year, make and model however claims that my vehicle is not listed on the recall list that came out around 9/15/2025. I contacted GMC and they cannot provide me with a specific reason as to why it’s not included.

Vehicle would not start. Vehicle was towed to GMC dealership for inspection. Vehicle diagnosed with "Fuel Pump Driver Control Module" issue and needed to be replaced. This was a known issue for the 2021 GMC Yukon: GMC Service Bulletin: #24-NA-139 (Release Date August 2024) Emission Recall: N212332040 (Release Date September 2021) Emission Recall: N252516900 (Release Date September 2025) However, this VIN was not covered under the recalls and payment was required out of pocket. Recall(s) need to be expanded to include additional 2021 GMC Yukon VINs - including this one.

My 2021 Yukon Denali (83264 miles), Fuel Pump Control Module failed causing car to lock up without any warning as my son was turning vehicle onto a main street. Car would not restart and wasn’t able to be put into Neutral to push it to side of road to a safer location. Police came and put cones around it until tow truck came the next morning. Tow operator got it onto a flatbed, which was difficult due to weight of the vehicle and not being able to put into Neutral (fortunately it was in 2wd which helped). It scares me to think what would’ve have happened if my son had been on the busy highway that he was planning to be on the next day or when it was on earlier that day. Vehicle is still at the dealership waiting on the replacement part which apparently is hard to get.

Recall N212332040 Car lost power and stalled on highway, at highway speed Dangerous Recall on fuel pump PCM did not cover this year vehicle based on VIN.

Vehicle engine stalled while driving in school parking lot. Safety concern as car when from “R” to “N” while backing up (2x). Engine would not turn on afterwards. Vehicle code P129F showed trouble with fuel pump power flow control module.

While driving back home on the highway (I-95) on February 26, 2025, my truck stopped accelerating right in the middle of the highway and cut off. Tried to crank it back up to no avail. I had it towed to the nearest GMC dealer which is GMC Coral Springs. They did an inspection and immediately communicated that the fuel pump module had failed and needed to be replaced. The only option at the time was to just have it fixed because I was out of warranty. At the time, I had about 100k miles on it and the guy at the dealer told me that he's supriesed it lasted that long as those modules usually go out before 100k mile. I got it fix and on March 1, 2025, the truck was ready for pickup. Fast forwarding, now GMC is recalling the 2021 Yukon with recall N252516900 for the same EXACT issue. I spoke to GMC corporate this morning to see if I can be reimbursed for the cost. When the rep Tina ran my vin, she states my vin wasn't attached to the recall number. So I was trying to understand that the issues are the same, why can't they reimburse me. Same issue on the same year truck. GMC refused to help me. I'm so disappointed because I'm not even sure why my truck wasn't included in the recall but has the same issue. I need your help. Please and thank you. (I contacted the dealer to have the email me a copy of my invoice for the service at the time, however I haven't received it. I will contact them again to see if they can email it again. But I will obtain a copy of it even if I have to drive out ther)

On 9/23/2024, I was driving my 2021 GMC Yukon Denali down the road, when the Engine seemed to lose power, and the accelerator no longer worked. There were no indications of any errors or alarms on the Dash, and all functions on the interior of the Cabin showed as normal. The vehicle switched into Neutral, and the engine shut off and I was unable to control or accelerate. This is a extremely serious situation and extremely dangerous in terms of Safety.

1. Fuel pump control mod 2. my car gave me only a second warning before it shut down entirely. I was somehow able to get to the side of the road. no car going to the car 3. It was replaced at an independent service station. They called GMC dealership for assistance on diagnosis. Dealership said this is happening 4. No warning lights at all. No car trouble at all. Car is fully up to date on maintenance This is only a 2021 car with such low mileage you expect to a car to run properly if well maintained. I called the GMC dealership and spoke to the Service manager and he just said that these things happen. Cars are complicated these days. I found that unacceptable since I could have been killed if someone was directly behind me and I could not get to safety. I spent $416 to get towed from a NJ towing company since AAA is not allowed to tow me on the Garden State parkway. . I spent $165 to get to Philadelphia to catch my flight since I did not have a car. I hope that this major shutdown of this car can be addressed and the answer is not just that cars are complicated these days. Thank you.

While driving at a low speed the vehicle suddenly hesitated, loss power and shut off. After several unsuccessful attempts to restart I had to have the vehicle towed to a local GM dealership. Their assessment was that the Fuel Pump Control Module was the cause but but my VIN was not associated with recall NHTSA Campaign Number: 21V739000 and they will not cover the replacement of the module that is now nearly impossible to get a replacement part for.

Car suddenly turned off while driving. Thankfully I was only going approx 10 miles an hour. Screen asked to restart engine but it would not start. Got stuck literally in the middle of road. Was not able to put into neutral to remove from roadway. The assessment from GMC dealer was a failed fuel pump control module. 900 miles outside of warranty. This could have been a much more serious and dangerous situation if I had been traveling on a busy highway at a much higher speed. This should be investigated further as my car is just now 2 years old and well maintained.
