2021 GMC YUKON Complaints

The contact owns a 2021 GMC Yukon. The contact stated while driving at an undisclosed speed, there was an unusual rumbling sound coming from the engine. In addition, the contact noticed that whenever the accelerator pedal was depressed, the vehicle failed to accelerate as intended. The contact stated that the failure had been ongoing for approximately one year or more. In addition, the contact stated that the failure was persistent and had occurred approximately ten times. There were no warning lights illuminated. The vehicle was not taken to the dealer nor an independent mechanic. The contact later received notification: NHTSA Campaign Number: 25V274000 (Engine and Engine Cooling); however, parts for the recall repair were not yet available. The manufacturer was not made aware of the failure. The failure mileage was approximately 50,000.

GMC has not responded for the recall of the engine. My vehicle is running bad. I need the vehicle to be service as soon as possible. My saftey depends on GMC keeping there promise to repair the recall engine.

While my wife was driving to pickup my son from school, the vehicle was stopped at a stoplight and the engine turned off approximately 1 mile after departing the house. After getting the vehicle towed to the dealership because it wouldn’t start, it was determined by the dealership that the engine was seized. The vehicle has 60,500 miles on it and is driven by a suburban woman and has always had all maintenance done at the dealership. The vehicle is parked in our driveway and there are no signs of oil leaks or anything else that would indicate a potential engine failure. This VIN was not recalled with the larger GMC 6.2L engine failure recall, however other 2021 model years were recalled. Recommend immediate expansion of recall due to the unforeseen engine failure while driving with no previous warning lights (oil or check engine) or other indications prior to seizing. This experience indicates that the initial recall was not sufficient enough to locate and identify all of the 6.2L engines affected by the poor quality control issues at GMC.

Subject: Assistance Request – Vehicle Engine Failure Shortly After Purchase I am reaching out for assistance regarding a serious issue with a vehicle I recently purchased. Approximately two weeks after purchasing the vehicle, the engine failed completely. I was driving it to pick up my daughter from school and when I went to go from stopping at a red light the engine light started flashing, the car said lowering for stabilization, and it started smoking and wouldn't go. I was almost hit due to the engine just stalling. When I was able to drive it was shaking and I couldn't go past 30. I made it to the dealership that was 7 mins away and had a guy from service come out. There wasn't any warnings before the engine went out. The dealership has informed me that I am responsible for the repair cost even though vehicles of the same year, make, and model have an active engine recall for this exact issue. Despite this, the dealership and manufacturer have refused to cover or assist with the repair, and there is currently no estimated time for replacement parts or a loaner vehicle. I have documentation from Greg Hubler on there diagnosis. I believe this situation may involve a warranty, recall, or consumer protection concern, and I would like to know what steps I can take or if your office can assist with resolving this matter.

I had a complete engine failure in my 2021 Yukon XL Denali while driving 70mph on the highway. My vehicle warning lights all of a sudden came on and my cruise control was disengaged. My vehicle started shaking and then started smoking. It was taken to our GMC dealership immediately and it was discovered that the engine had failed even though my VIN is not listed in the L87 Recall. No warning lights appeared prior to this failure. I will attached our invoice from the dealership and their description of the problems.

I looked up recall information on NHTSA.GOV site and found my car has a recall for engine problems. My GMC app says there are no recalls related to my vehicle and I have never received a communication from GMC stating a recall has occurred.

While operating the vehicle at normal highway speed, the engine suddenly failed without warning. The vehicle immediately lost power, forcing me to coast to the shoulder. This created a dangerous situation in active traffic. The vehicle was later towed to an authorized GM dealership. The dealer inspected the vehicle but refused to provide assistance or take responsibility for the engine failure. Based on the symptoms and information available, the failure appears to be caused by a known GM engine defect. This issue poses a serious safety hazard since the engine can fail abruptly during highway driving, increasing the risk of accidents or injury. I am requesting that NHTSA investigate this matter and that GM be held accountable for addressing this known defect.

“Service safety restraint” light comes on and the dealership cannot pin point exactly what the issue is without taking the entire seat and air bag out. It’s come on 3 times. First time was linked to the overhead console needing replaced. Months later the light came on again and a seat harness connection was bad. It was replaced and light was off. 8 months later the light is back on again and they replaced the connection again and the light is off for now. This is a safety issue and should be a recall!

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 GMC Yukon Denali is affected by NHTSA Recall #25V-274. The recall notice states that defects in the engine’s connecting rod and/or crankshaft can cause engine damage and failure, resulting in sudden loss of propulsion and increasing crash risk. The recall status for my vehicle is currently listed as “Incomplete – Remedy Not Available.” My dealership confirmed that no repair is available and further told me that GMC will not authorize a buyback, trade-in, or loaner vehicle until a remedy is developed. This has left me with an unsafe vehicle that cannot be repaired, yet I am still obligated to make monthly payments. This defect creates a serious crash risk because the engine may fail and the vehicle could lose all propulsion without warning. My family is forced to either risk driving a defective vehicle or go without reliable transportation. Dealer Interaction •Dealer confirmed that the recall is active but has no available remedy. •Dealer stated GMC will not authorize a buyback, trade-in, or loaner vehicle until the recall repair is developed. •I am effectively stranded with an unsafe vehicle and no safe options. Remedy I am requesting that GMC be required to: 1.Buy back my vehicle under federal recall and warranty obligations; or 2.Provide a safe, comparable loaner or replacement vehicle at no cost until the defect is remedied. If a loaner is provided, I will continue making my monthly payments on my Yukon Denali.
