2021 GMC Yukon owner complaints (15)

• ENGINE,BACK OVER PREVENTION,FORWARD COLLISION AVOIDANCE

  I bought the vehicle used with 40,000 miles it’s has 100,856 now the engine shot off while I was driving and brought it to the GMC dealer that GM instructed me to the dealer had me pay 284.95 for inspection and then try to charge me 1284.95 for a complete tar down of the engine because of misfiring and ESC error codes.

• POWER TRAIN

  Transmission abruptly failed after only 110k well maintained miles

• POWER TRAIN,ENGINE,FUEL/PROPULSION SYSTEM

  Engine overheated and performed an emergency shutdown while driving through Atlanta on my way to vacation with my family. We lost propulsion and had to cross 5 lanes of traffic to find a shoulder to pull over to. The engine shut down and we were left stranded 500 miles from home with our 3 children in a boiling car. The vehicle was inspected and passed the recall test 6 weeks prior to this incident. After the first failure we attempted to extend our power train warranty to which we were told it had too many miles by GM. The GM dealership and service center where the vehicle was towed confirmed the engine needed to be replaced and GM confirmed it falls under their extended warranty. However, GM refuses to cover any additional expenses incurred from their engine failure.

• ENGINE

  engine failure causing vehicle to be unsafe to drive. our vehicle was not included in the L-87 loss of propulsion GMC recall even though it is a 2021 Yukon 6.2L. the engine failure is same as those being recalled. vehicle is currently at Cardinale GMC in Seaside CA waiting repair. the only warning of the impending failure was loud noises coming from engine compartment while driving on the freeway. Cardinale confirmed the problem and our extended warranty is covering repair costs. it seems that GMC should have included our VIN in the recall.

• ELECTRICAL SYSTEM,AIR BAGS,SEATS

  The driver's seat inboard airbag assembly and internal structural wiring harness failed due to a direct short circuit, completely deactivating the vehicle's supplemental restraint system. General Motors has a known engineering bulletin for this issue (#23-NA-085), noting that sharp internal seat frame components slice the airbag wiring harness. Rather than permanently fixing this structural design flaw while under warranty, dealership technicians repeatedly executed temporary, non-compliant field patches, including plastic zip-ties and Velcro tape inside the cushion. These temporary patches continuously failed, leaving the airbags disabled. Furthermore, the vehicle was sold under "Certified Pre-Owned" designation with an active, uncompleted 2020 manufacturer Customer Satisfaction Program Campaign (#N202310850-02) for this exact airbag circuit defect. Component failed & available for inspection: The driver's seat inboard airbag assembly and internal structural wiring harness failed due to a direct short circuit. The components are available for inspection inside the vehicle at the servicing dealership. Safety risk: Safety was put at extreme risk because active Diagnostic Trouble Code B14DC completely deactivates the airbags. This means the airbags may fail to deploy in a collision, leaving the driver completely unprotected in an accident. Confirmed by dealer: The problem has been explicitly reproduced and confirmed by an authorized franchise dealership across seven separate service visits spanning from August 2025 to June 2026. Inspected by manufacturer/others: The components have been physically inspected multiple times by authorized franchise dealership technicians acting on behalf of the manufacturer. Warning lamps & symptoms: The vehicle displays "Service Safety Restraint System" warning message on the dashboard. The warning lamp first appeared on August 26, 2025, at 78,472 miles while the vehicle was strictly within its CPO warranty

• ENGINE

  Took my vehicle in for general maintenance upkeep (oil change, tire rotation, vehicle inspection) and was notified my engine is already showing signs persistent with the recall on the 6.2L L87, specifically not holding oil. The dipstick was not showing signs of any fluid being in the vehicle.

• AIR BAGS

  1. Component / System Failed: The Supplemental Restraint System (SRS) / Driver’s Inboard Seat Airbag circuit has chronically failed, leaving the vehicle's primary safety restraint systems disabled. The faulty components and the physical service records documenting the failure are fully available for inspection upon request. 2. Safety Risk: The driver's safety and the safety of passengers are put at extreme, immediate risk. Whenever this failure occurs, the "Service Safety Restraint System" warning illuminates, which completely disables the airbag deployment system. Driving a heavy passenger vehicle (2021 GMC Yukon) without active driver-side airbag protection leaves the operator exposed to severe injury or fatality in the event of a collision. 3. Dealer Confirmation / Reproduction: The problem has been reproduced, diagnosed, and confirmed by an authorized dealership (Quirk GMC in Manchester, NH) on five separate occasions spanning from August 2025 to June 2026. 4. Inspections: The component has been repeatedly inspected by the manufacturer’s authorized dealer technicians at Quirk GMC. It has not yet been inspected by police or insurance representatives, as no crash has occurred. 5. Warning Lamps / Symptoms: The failure is preceded by the "Service Safety Restraint System" dashboard warning lamp and message illuminating. This symptom first appeared in August 2025 at 78,472 miles and has continuously reappeared shortly after every subsequent repair attempt made by the dealership, indicating a continuous, unresolved defect in the vehicle's safety manufacturing or a severe failure in the manufacturer's diagnostic repair procedures.

• POWER TRAIN,AIR BAGS

• ENGINE

  On May 27, 2026, I was on my way home from work when I went to accelerate the vehicle and all the sudden it started shaking and the check engine light came on with the EBS. I was able to get the vehicle to a repair shop local the next day, who took the car apart. What was thought to be an easy fix of spark plugs and fuel injector, became even more after they put back together and the cylinder was still misfiring. After several hours of taking apart the engine, the mechanic determined that the hydraulic valve lifters had failed. This has been an ongoing issue with with the 5.8L V8. Due to a recall not being under the vin yet, i have now incured a $16k expense to add an engine to it after i purchased it in Nov of 25 at $97,000. This is a saftey issue and luckily no one was hurt when the car started shaking and couldn't go over a certain speed. I want this reviewed and looked at for possible reimbursement as there have been several other vehicles with the same known issue.

• ENGINE AND ENGINE COOLING,ENGINE

  The contact owns a 2021 GMC Yukon. The contact stated that while pulling into the yard, the vehicle made an abnormal clanking sound and a hammer-like sound. No warning light was illuminated. The contact stated that the failure was related to NHTSA Campaign Number: 25V274000 (Engine and Engine Cooling), but the VIN was not included. The vehicle was taken to the local dealer, where it was diagnosed with metal fragments inside the engine. The vehicle was repaired, but the failure recurred while driving a month later. The manufacturer was contacted, but no assistance was provided. The failure mileage was approximately 76,000.

• ENGINE

  I am filing a complaint regarding my 2021 GMC Yukon due to a serious engine failure involving the camshaft, lifters, and crankshaft. The vehicle began exhibiting engine ticking and knocking noises, rough idle, loss of power, and reduced performance. These symptoms progressively worsened and ultimately resulted in major engine damage. The vehicle was diagnosed with failed lifters and camshaft damage, which required extensive repairs. In addition, the crankshaft failed, resulting in catastrophic engine damage and making the vehicle unsafe to operate. These are critical engine components that should not fail prematurely under normal driving and maintenance conditions. The most serious concern is safety. The engine's loss of power and deteriorating performance created the risk of sudden failure while driving. A vehicle that loses power in traffic, while merging, crossing intersections, or traveling at highway speeds can create a dangerous situation and increase the risk of a crash. Occupants and other motorists could be placed at risk if the engine fails without warning. My vehicle has been properly maintained and serviced. Despite regular maintenance, these major engine components failed unexpectedly. I am aware that other owners of GMC and Chevrolet vehicles equipped with similar engines have reported comparable camshaft and lifter failures, suggesting a potential defect rather than an isolated incident. The failure resulted in significant repair costs, loss of vehicle use, and concerns about the long-term reliability and safety of the vehicle. I believe these engine failures may indicate a manufacturing or design defect affecting 2021 GMC Yukon vehicles. I respectfully request that NHTSA investigate camshaft, lifter, and crankshaft failures in the 2021 GMC Yukon and determine whether a safety-related defect exists that warrants corrective action or a recall.

• ENGINE AND ENGINE COOLING,ELECTRICAL SYSTEM

  The contact owns a 2021 GMC Yukon. The contact stated that while driving approximately driving 45 MPH and turning onto an exit the vehicle suddenly reduce speed and lost power and the message "Press Start" had displayed.

The failure mileage was 42,000.

• POWER TRAIN,ENGINE

  The contact owns a 2021 GMC Yukon. The contact stated that while driving at an undisclosed speed, the vehicle would independently activate Limp mode and would not accelerate past 30 MPH. In addition, the vehicle would not shift into the Reverse gear as intended. The vehicle was taken to a local dealer, where it was diagnosed with error codes: P0777 and P18A1. The vehicle was not repaired due to parts being on backorder. Upon further investigation, the contact related the failure to an Unknown NHTSA Campaign; however, the VIN was not included. The manufacturer was made aware of the failure. The failure mileage was approximately 90,000.

  Post-Recall Low Oil Warning + Performance Issues on 2021 GMC Yukon Denali – Campaign 25V274000 Vehicle: 2021 GMC Yukon Denali, 6.2L V8 Recall: 25V274000 Owner: One owner since new (purchased 2021) I had recall campaign 25V274000 performed on my vehicle. This was the first low oil warning I have ever received since purchasing the SUV new in 2021. I have always followed the vehicle’s oil life monitor with no prior issues. The change oil light appeared at roughly 7,500 miles after the recall service (when I already had a service appointment scheduled). About one week later, the low oil warning came on. I had the vehicle towed to the dealership and did not drive it after the warning. Since the recall service, I have also experienced performance issues including noticeable stuttering that was really evident before I towed it in. The dealership initially agreed to a consumption test but later acted like it was not needed, said everything was fine, and were dismissive — blaming me for not following their sticker. I am concerned the recall remedy is not fully effective. Please investigate this matter. Thank you, [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
