The contact owns a 2021 GMC Yukon. The contact stated that while his wife was driving 65 MPH on the highway at higher speeds, the vehicle shuddered abnormally. The check engine, ECU, and traction control warning lights illuminated, and the message "Shut off Vehicle as soon as Possible" was displayed. The contact's wife pulled over to the shoulder of the road, and the vehicle was towed to an independent mechanic for diagnosis. The mechanic retrieved dDTCs: P0307 and P050D, indicating a failed roller lifter, valve spring, and valve roller lifters. The vehicle was later towed to a local dealer, where the dealer diagnosed that the lifters had failed and needed to be replaced. The manufacturer was notified of the failure. The failure mileage was approximately 95,000.
The contact owns a 2021 GMC Yukon. The contact stated that while driving at various speeds on several occasions, the vehicle jerked and the transmission shifted hard into 1st and 2nd gears. The message "Service Safety Restraint" was displayed. The vehicle was taken to an independent mechanic, where it was diagnosed with a failed valve body. The contact was informed that the valve body or the transmission needed to be replaced. The manufacturer was notified of the failure. The failure mileage was approximately 88,000.
Crankshaft / Camshaft caused catastrophic engine failure while on a family road trip leaving family and kids stranded on the side of the highway for hours. 2021 GMCs are notoriously having this issue but they refused to include our VIN in the recall. It cost us almost 13,000 to replace with a brand new engine and only 4 days after picking up from dealership the vehicle stopped working and shut off at a light in the middle of the road. GMC has been no help and won’t cover anything.
Water is entering the passenger cabin through failed front sunroof drain tubes on both the left and right sides. The drains discharge inside the A pillars rather than to the exterior, pooling in the driver's side floorboard. An authorized GMC dealer diagnosed the cause in writing on August 12, 2026 as rubber grommet shrinkage and hardened internal buildup preventing water from flowing through, on both the left and right sides simultaneously. The identical bilateral failure mode indicates a component or assembly defect rather than debris blockage. Water is accumulating in the driver's footwell in proximity to cabin electrical components and the fuse block area, creating a risk of electrical shorting, connector corrosion, and circuit failure. Mold has developed in the front carpet and padding on the driver's side, and water intrusion staining is present on the passenger side. The dealer has quoted 2,727.16 to replace the drain tubes and the mold-damaged carpet and padding. The vehicle entered service on February 5, 2025 and has 45,211 miles. GM has issued service bulletin 20-NA-219 addressing sunroof drain hoses on 2021 Yukon, Yukon XL, Tahoe, Suburban, and Escalade models.
Had a valve body failure in mid XXX. The vehicle would not go into reverse and drove it in limp mode to a dealership about 5 miles away. Fortunately they were able to get a new valve body and repair it in one day. Cost was approximately $3,500 and not covered by warranty. The vehicle had about 110,000 miles on it at the time. This is a known defect on this vehicle and a recall should be initiated. Had we started our trip from [XXX] back to [XXX] before the failure occurred, we likely would have been stranded on the highway, or worse.

My 2021 Yukon Denali received the Recall 25V-274 oil fix and I am now experiencing an active light engine knock. My gas mileage has reduced significantly and I am having to add oil in between regular oil changes. Not only does it burn through oil and fuel faster but I now get charged an extra fee for "Premium oil". My oil changes cost me roughly 40 dollars more now. (140 instead of 100) I don't feel as if this fix with the oil change has improved anything and that the cost to maintain the vehicle has only gone up. I am still worried this vehicle will break down on my next road trip.
Fraud and gross negligence by General Motors, Orr GMC and Sewell Buick GMC.
My 2021 GMC Yukon began experiencing severe engine problems, including shaking/rough running, a noticeable ticking/knocking noise from the engine, and a flashing check-engine light. The vehicle also displayed Service ESC and traction control warnings and exhibited symptoms of an engine misfire. I took the vehicle to a dealership for evaluation. I was advised that the problem may involve failed lifters and that the vehicle could be out of service for several weeks for repairs. I was also advised that the repair could be very costly. At this time, I have not been given a final diagnosis, so the exact internal engine component responsible for the failure is UNKNOWN. I am concerned that the condition presents a safety risk because the engine is running extremely rough and the check-engine light is flashing. I am afraid the engine could lose power or fail while the vehicle is being driven, potentially putting me, my passengers, and other motorists at risk. I have also become aware of NHTSA's investigation involving failures of the 6.2-liter L87 V8 engine in GM vehicles, including the GMC Yukon, as well as reports of engine failures occurring after certain repairs or recall remedies. This has increased my concern about whether repairing or replacing individual engine components will permanently resolve the problem. I am submitting this complaint so that my vehicle's symptoms, dealer evaluation, and potential engine failure are documented. The vehicle and affected components are available for inspection upon request. The dealership has evaluated the vehicle, but a final determination of the exact cause has not yet been provided.
While driving my 2021 GMC Yukon Denali with the 6.2L L87 V8 on a high-speed highway near Somers Point, New Jersey, the vehicle suddenly began bucking and the accelerator stopped responding normally. The vehicle rapidly lost propulsion while I was surrounded by highway traffic and approaching a bridge. I was fortunate to get the vehicle onto the shoulder before reaching the bridge. I was then stranded on the shoulder of a high-speed highway, where the disabled vehicle created a serious safety risk to me and other motorists. The engine shut down and would not restart. It initially cranked as though it was attempting to start, but it did not start. I received a diagnostic alert stating, “Service the engine and transmission system immediately.” The vehicle required a tow. The tow operator later reported that it appeared locked up and could not be shifted into neutral. The vehicle has approximately 77,000 miles and has been serviced regularly. Its most recent oil-change sticker indicated the next oil service was due at approximately 81,000 miles. While safely pulled over, I checked the engine-oil dipstick and confirmed that the engine had oil, with oil visible across the dipstick’s normal measuring area. Despite this vehicle having the 6.2L L87 engine and experiencing a sudden loss of propulsion and no-start condition, its VIN does not currently appear in GM’s public recall lookup for the existing L87 recall. The vehicle is being transported to an authorized GMC dealer, and the precise failed component has not yet been confirmed. This sudden loss of propulsion created an immediate risk of a serious highway collision, particularly because it occurred immediately before a bridge. I understand NHTSA is investigating continuing L87 engine failures, including failures involving vehicles outside the original recall population. I am submitting this complaint so this incident is formally documented and considered as part of that investigation.
Lifters failed under 80k miles. Had lifters replaced with gm parts and engine is continuing to eat up oil and lifters are failing again in less than 3 months after the repair. Vehicle was out of warranty and all costs were out of pocket including a rental for over a month bc parts were on backorder
My 2021 GMC Yukon Denali with approximately 88,000 miles developed a significant engine knocking noise and was towed to a GMC dealership for diagnosis. The dealership confirmed diagnostic trouble code P0301 (engine misfire) and documented a “knocking noise in lower end at piston rod crankshaft area.” The dealership advised that my vehicle is not currently included in the existing GM recall for certain 6.2L L87 engines. The vehicle has the 6.2L L87 V8 engine. I am concerned because the documented knocking is located in the lower engine area involving the piston/connecting rod/crankshaft area, which is consistent with the type of internal engine failure associated with the L87 engine investigation and recall. I am concerned about the possibility of sudden engine failure and loss of propulsion while driving. I am requesting that NHTSA investigate this failure and consider whether vehicles outside the current recall population should also be included. I also recently experienced an engine replacement on another 2024 GMC vehicle. I am providing that information as additional customer experience, but I am not claiming that the two failures are necessarily caused by the same defect.
this year model was recalled do to engine problems. Ours wasn't one that was on the recall list. We ended up having to have the motor rebuilt and cost us around $7000. We have seen where these models are still having problems, so i wanted to report our problem and the money spent to get it fixed.
