2021 GMC Yukon fuel system complaints
Page 3 of 3: complaints 41 to 57 of 57, newest first, as owners wrote them.
Twice in a five day span vehicle stalled out, acting like it is not getting fuel. Each time it took several minutes of trying to restart and getting below fuel tank to give it a couple knocks to get it to start. Both times there was atleast a half tank of gas. Each time the car was running well when it suddenly slowed down on its own, the first time I was on a busy street resulting in the need for a tow and I had my grand baby with me. The second time it was an isolated road and surprisingly I had cell service to call for assistance. The tow truck driver told me he thought it was the fuel pump. I looked up my vin but it isn’t listed as one of the affected vehicles in the GMC Yukon recall, however it certainly seems like it is. I had no warning of any type with each incident, the car simply acted as if it ran out of gas. I have an appointment with a local garage. Additionally when this happens the vehicle does not let me shut it off. The engine isn’t running but I can’t power down the electronics system.
I owns a 2021 GMC Yukon. My wife was driving approximately 70 mph when the vehicle suddenly stalled. The vehicle would not restart. The vehicle was not able to go into neutral. The vehicle was towed to the dealership who diagnosed that the fuel pump module failed and needed to be replaced. The vehicle is getting repaired but not covered under warranty or by recall. The manufacturer was made aware of the failure. The approximate failure mileage was 14000

Major accident waiting to habit and back ordered parts on a expensive machine
The contact owns a 2021 GMC Yukon. The contact stated while driving 25 MPH, upon accelerating from a light, the vehicle began to shake and decelerated and failed to accelerate and exceed 25 MPH. The vehicle accelerated, jerked, and stalled. The check engine warning light was illuminated. The vehicle was taken to the local dealer, where it was diagnosed that the fuel pump control module needed to be replaced. The mechanic informed the contact that the parts were on backorder. The vehicle was not repaired. The contact stated that the failure was related to the federal safety agency Campaign Number: 21V739000 (Fuel System, Gasoline). The manufacturer was notified of the failure and opened a case. The failure mileage was approximately 67,150.
While traveling on the interstate at 70 mph with husband and child inside, the vehicle started shaking and stalled. Had to glide off onto an exit ramp where the vehicle stopped and would not restart. Onstar ran diagnostics and came back with code P129F.
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 the federal safety agency 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.
I was driving about 40 mph on a rural road when my vehicle stalled. I thought I was out of gas but I wasn’t. I tried to turn it around but I had no power. I pressed the gas but it would not do anything . It would not crank back up. I called my husband and he came and put gas in it and it still wouldn’t work. I was left stranded in the middle of the road on a curve. No warning lamps were on that I could recall. I’m having it towed to the dealer today. There are 39K miles on the car.
On Sept 17, 20123 my SUV stalled while driving in heavy traffic causing a sudden and unexpected loss of power and putting me in jeopardy of a crash My vehicle was towed to the dealer as it would not start. The dealership replaced the Fuel Pump Power Control Module. There is a recall for this part on 2021 Yukon. My vehicle was not included in the recall. Further, this make /year SUV has 11 safety recalls . I contacted GMC and opened a case. No one has contacted me to discuss the issue. I called several times and have been provided little information other than “the Regional Service Rep” will contact me and that GMC sent an email to the dealership. I have been repeatedly told my vehicle is not part of the recall. Logic dictates otherwise. I do not believe the part failure was a coincidence. Rather, the recall should have included my SUV. Further, GMC should contact me to discuss this issue as a consumer with a safety concern. I cannot operate this vehicle with confidence knowing that some of the other recall items could cause a sudden loss of power. I do not have trust in GMC to accurately identify vehicles with issues. I want GMC to explain how any driver should feel safe to operate a vehicle on the roads under these facts- knowing a vehicle was not included in one of the recalls and could be left out of others. I also question why GMC makes a vehicle that cannot be put in neutral without the vehicle running. This creates a whole other safety issue if the vehicle stalls on a highway and needs to be pushed off the road. I had an issue with the tow because of this fact. In summary for required information: 1)Unknown if the part is available as the dealer removed it 2) I was in traffic and my vehicle stalled 3) The dealer confirmed the part needed to be replaced as the SUV would not start 4) See number 1 5) There were no warning lights or other. The SUV stalled. I know GMC wants to make a profit. It should not be at consumer’s safety and peace of mind..
The contact owns a 2021 GMC Yukon. The contact stated while driving approximately 80 MPH, the vehicle stalled.

The vehicle was not starting and after 3 attempts it started, but a strong smell like gasoline came inside the car, and as I checked, fuel was running all the way to the ground. Major hazard! The vehicle was taken to the dealership and diagnosed with a leak in the High-Pressure Fuel Pump. According to the service advisor NOT COVERED under powerterain warranty. The part just went bad, and needs to be replaced. However, the vehicle has been in the service department since July 3 (Now it is July 18) and the part is in back order and no news as of when my vehicle will be fixed. My vehicle is a 2021 and I do not understand how a part is not available, or discontinued (according to parts department). I need my vehicle fixed!
The vehicle had a sudden loss power shortly after i started the vehicle. When I pressed down the gas pedal, the vehicle turned off. It was only a 20 mph zoned residential neighborhood so I was able to safely coast to the side of the road. I dont think i could have safely gotten to the side of the road if it had been on any type of a multi lane road. There was no warning, no lights, no sounds that there was a problem. I had the truck towed to the local dealership as i was 120 miles from home. The mechanic at dealership said it was a faulty “fuel pump power control module“ and that they are failing a lot. Last I heard that the part was on nationwide back order. There was a recall for this very same problem over a year ago but my vehicle is not part of the recall. Yet the problems are still occurring with many similar vehicles (Tahoe / Yukon)

On a road trip out of state we stopped for gas. We got back on the road and few miles out the car suddenly slowed and gave a message on the screen something about acceleration. We pulled over and next the reverse didn’t work. We stayed overnight then next day the reverse still did not work. We were able to place in drive and continue on but we don’t have fully functioning reverse mode.
