2021 GMC Yukon complaints

In January 2021, I purchased a new 2021 GMC Yukon Denali from a GMC dealership, which currently has only about 27,000 miles. To date, several recalls have been assigned and completed for my vehicle. per the websites for GMC and your agency. However, based on published recalls for my vehicle and a repair that is currently underway, I have reason to believe that my vehicle should have been subject to three prior recalls for which it was not [NHTSA ID Numbers: 20V735000 (Front Seat Bolts), 25V274000 (V8 Engine Failure, and 21V739000 (Fuel Power Control Module] Currently, the fuel pump control module is being replaced at a local GMC dealership because it failed last week and left my stranded at home. GMC issued a recall for this in 2021, but my vehicle was not included. Aside from risk and inconvenience, this is also costing my over $300 for a rental. Secondly, though my vehicle's make/model/year is cited in GMC's ongoing engine failure recall, which you are investigating, I have not received a recall notice. I note GMC's financial interest in minimizing vehicle's it recalls for such a costly repair. I have inquired with GMC and two of its dealers and have only received reiterations that my vehicle has not been subject to GMC's recall, which I already knew. I have not been given any explanation for why my Yukon has not been recalled despite my inquiries. Lastly, GMC issued a 2021 recall for front seat bolts; however, I did not receive a notice for my Yukon. I have occasionally fe

My vehicle is currently in repair due to a known issue with GM. GM has put out a Technical Service Bulletin 20-NA-038 referencing a "well-known" problem with Cylinder 5 failing in 2021 5.3L and 6.0L engines. However, there has not been a recall. Ironically, there were other vehicles brought to the dealership (Sam Boswell GMC in Enterprise, AL) for the same repair on the same day as my vehicle. I'm hoping to get an initiative started for a recall

We experienced catastrophic engine failure consistent with the current outstanding recall. A GM dealership replaced the parts that failed (crankshaft and connecting rods) however, based on the recall that was issued, the serial number on our engine would qualify under the remedies indicated by GM for a complete engine replacement, however, our VIN number is not currently included in the recall even though our year, make and model for the car and engine are consistent with other recalled vehicles. The GM dealer indicated that the catastrophic engine failure was not due to any lack or neglected maintenance and felt that our vehicle should be included in the recall. My wife and two toddler children primarily use this vehicle and I have serious concerns about their safety and would like to feel confident about their use of the vehicle.

Air bags never deployed . My car is totaled. The driver’s car hit so hard the front of her car was in my third row of seats. I was taken to the hospital for chest pains since the seatbelt was the only thing that saved me .

Problems with the engine shifting gears stalling delayed or won’t engage hard shifting while it’s in motion something’s going on with the engine we’ve called several and had it serviced times of times to ask them what was going on with it in Newport Oregon you can fill it still when you drive. The problem still is not fixed. It’s been happening since we purchased it took it in right away. we’ve asked if our Vin number has come up for a recall repairs we are worried for safety and are currently parking in the car because the dealership is unable to fix what is wrong with the car. They’re telling us there is something wrong and are aware of the recall and won’t fix the problem dealership refuses to take the car they don’t want it without the recall fixed due to safety concerns. you can definitely fill it when you drive I’m not exactly sure what the other issue if with the sounds it’s making when the issue keeps happening but it’s scary There is the recall on it. They are not taking into consideration or the seriousness of the situation and the safety of lives.

My engine is currently experiencing loud knocking/shaking. It worsens as my vehicle is accelerating it is causing my engine to lose ability to accelerate which has posed a safety concern. This vehicle is my main source of transportation for my family. We have taken this vehicle to the dealership where they were unable to service due to the recall not being open and available and i have contacted GM customer service with no remedy to be issued at this time. The dealership cannot perform any maintenance pertained to the recall and yet cannot remedy. I am concerned for my family's safety. I was advised that i shall continue to drive the vehicle until it breaks down or the recall is open for repairs.

GM may be installing recalled engines into other vehicles through warranty replacements, avoiding recall accountability. I purchased a 2021 GMC Yukon built before recall N252494002. Before my ownership, the original engine failed and was replaced under warranty at 24,339 miles on 9/16/2024. The dealer verbally told me it was new, but it had salvage yard markings and no serial number—indicating it was used. This donor engine was likely from a vehicle later covered by the recall. GM appears not to track donor VINs for warranty replacements, meaning recalled engines can remain in service without repair. This creates a serious safety risk and allows defective engines to escape recall compliance. I urge NHTSA to require manufacturers to track and report donor VINs for used engines and major components installed under warranty so they remain subject to applicable recalls.

Loss of some power. No haul power.

Dealership refused to inspect engine and provide new oil in regards to recall, they charged me $208.75 for oil that was supposed to be completed under recall L87 for GM

The electronic solenoid in the valve body failed and it is available for inspection. it was struggling to shift on freeway at speeds of 65 mph and i would lose power. the vehicle was inspected by a gm dealership service man. there were no warning lamps when part started to fail, luckily when I parked the vehicle would not go into gear and then the warning light (check engine light) came on.

The contact stated that the gear shifter failed to shift into the intended gear. There were no warning lights illuminated. The vehicle was not diagnosed or repaired by an independent mechanic or dealer. The contact received notification of NHTSA Campaign Number: 25V274000 (Engine and Engine Cooling); however, the part to do the recall repair was not yet available.

Engine started missing out. After taken to dealer, cylinders 5 and 6 were filled with oil. New engine is needed, and is on nationwide back order as thousands of these are effected.

While driving the vehicle, the engine started to make a knocking noise and we experienced illumination of the check engine light. We also experienced engine performance issues with hesistation and reduced acceleration. We were able to take the vehicle to a GM dealer and it was determined that the lifters and crankshaft were defective and need to be replaced. There is a warranty out for 2021 GMC Yukon Denali vehicles that were manufactured less than a year after ours that have currently have a recall issued by GM for the same problems that we experienced. My wife and two young children, ages [XXX] and [XXX] , frequently ride in this car and catastrophic engine failures put their safety and livelihood at serious risk.

A valve in the transmission is sticking causing a loss of power, engine light warnings to flash, and hard gear shifts from park to drive or reverse. First occurred on 5/25/25, went to the dealer service department on 5/26/25. Part still not available and it’s been sitting at the dealership since.

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.

See attached document for complaint.

Knocking, banging, engine noises, illumination of the check engine light, engine performance issues at high rpm and fluttering at low rpm. oil consumption but not leaking. The engine needs to be replaced as the bearing is shot, cylinder 7 is shot. I believe this is directly related to NHTSA Recall #25V-274 and Manufacturer Recall #N252494000

Per the dealership where we purchased our vehicle, one lifter gave out and damaged the camshaft. Since there are no guarantees if we replace one lifter this will not happen again. We chose to purchase a new engine rather than purchasing a rebuilt engine. I don't know if this qualifies as a safety issue but we were afraid to drive our vehicle. It has now been at the dealership since May 15 waiting for a new engine. The following warnings showed up on our dash: leveling suspension engine failure stability control head on collision Our GMC denali has a 6.2L v8 engine

Acceleration failing. Knocking of motor, winding sound, a huge clicking sound when accelerating, and engine burning very excessively. We have 4 children and its very unsettling to say the least on a 100,000 vehicle we paid for. I hope and pray you include our vin number with the 6.2 recall as the dealer is well aware of this problem long before the current recall. It's very unfortunate that our vin wasn't part of this very serious safety issue. Thank you

The GMC is starting to loss power in the engine. GMC has not send me an appointment to inspect the engine. This vehicle is my only transportation to work and doctors appointment. This is not fair for a powerful company like GMC is not taking the ownership of the engine in this vehicle. I need action asap. Please assist. Thank you

Vehicle: 2021 GMC Yukon Denali Component: Fuel System, Gasoline – Fuel Pump Control Module Incident Date: 7-10-2025 Mileage 61,263 Location: SR 2006 Coats, NC Summary of Complaint: While my wife was pulling out of our neighborhood in our 2021 Yukon Denali, the vehicle suddenly shut off while navigating a slight curve. It came to a complete stop in the roadway and could not be restarted. The engine would not crank, and the vehicle could not be shifted into neutral, making it impossible to move out of traffic. The Yukon remained disabled in the roadway for over an hour and ultimately had to be towed. Upon inspection, the dealership mechanic immediately identified the issue without even running diagnostics. He confirmed it was a failed fuel pump control module, which he stated is a common issue with this model. This failure represents a serious safety risk, particularly had it occurred on a high-speed interstate or in dense traffic. A sudden loss of power and inability to move the vehicle can result in dangerous roadside situations or collisions. GMC needs to address this recurring defect before it leads to more severe incidents or injuries. No warning lights or indicators appeared prior to the failure.

I received an official safety recall notice from GM (Recall Number N252494000) for my 2021 GMC Yukon due to a defect in the engine's connecting rod or crankshaft components. GM stated that this defect can cause engine failure and loss of propulsion, which significantly increases the risk of a crash. The notice also confirmed that parts to fix the issue are currently unavailable and provided no timeline for resolution. Despite the serious safety risk, GM and my local dealer have not offered a loaner vehicle while waiting for the repair, leaving me without a safe means of transportation. I am filing this complaint because I believe GM is not taking sufficient steps to protect customers from a known and documented safety hazard.

Vehicle engine seized. Approx 80,000 miles. After discussion with mechanic and dealership, this problem is common with GM L87 6.2L gas engines. Engine seize likely caused from defective crank bearings. No warning light, oil was in engine, vehicle recently serviced. No oil warning light on dash or temperature sensor on dash, or check engine light. Drove car on road trip - when arrived at destination parked car - few hours later went to start vehicle and wouldn't start. My VIN is not subject to recall - currently; however, many 2021 GM engines are recalled. Why wouldn't my 2021 engine be included in this recall? Or all customers notified of potential dangers? I frequently drive carpools with many children in the car - and an engine seizure at any point while driving puts me as driver and any passengers at risk. Vehicle currently being towed to dealer for 2nd diagnosis. First autobody shop diagnosed with engine seizure.

I have again taken my vehicle in for about 8th time trying to get an understanding of why my vehicle vibrates. Again, I was told that the problem could not be duplicated. However, when picking up, I had a discussion with the service manager whom had driven the vehicle as well.. He stated that he felt and heard something from the rear end. I explained that I had the differential fluid change about 2 months ago due to a growling noise when making a left turn. He printed the service bulletin for the differential and put it with my paper. I was told I would receive a call from him the following Monday to bring my truck back in to further investigate because it sounded like the vehicle has a bad rear end. I have not received a call back and have attempted to make contact with service manager twice. My powertrain warranty is almost up and fear that after is when they will finally make a diagnosis of the issue. My engine and transmission vibrates and the whole vehicle shakes when cranking and turning off. This is in addition when driving at any speed. At idle it vibrates and can be felt throughout the entire vehicle. I am afraid that this vehicle is going to stall or fail why traveling with my family. The problem is only getting worst, transmission fluid temperature is starting to rise higher than normal. I am just afraid at this point that I have wasted thousands of dollars on a vehicle and GMC is not willing to fix the problem. I have the L87 and just not understanding with the pr

While driving the vehicle shut off, leaving my family stranded in the middle of traffic. It was a 90+ degree day and my family was stuck in a hot car unable to move off the roadway. This was very unsafe. No warning lights prior, the engine just stopped. After multiple times trying to restart the vehicle, the battery died. After waiting several hours, the vehicle was towed to the local dealership where it was determined that the driver fuel control module needed replaced and re programmed.

My Denali had no previous problems, I pull out of the driveway and I felt a hard Lunge forward without me pushing the gas. Almost like the car accelerated like a hard jerk. I pulled over because I thought I had been hit by another car. After checking no cars around, I pull back out and I felt it again a hard lunge forward. If someone would have been in front of me I would have hit the car in front of me without even pushing the gas. These GMC are dangerous and can’t trust my vehicle. After getting stranded on the road found out the transmission went out. My suv is now being repaired at GMC at my expense. Only had the vehicle 6 months. Recall the transmission.

The contact owns a 2021 GMC Yukon. The contact stated that while driving at an undisclosed speed, there was an abnormal knocking sound coming from the engine compartment before the vehicle lost motive power. The check engine warning light was illuminated. The contact pulled over to the shoulder of the roadway, where the failure persisted. The vehicle returned to normal functionality, but the failure became a regular occurrence. The vehicle was taken to the dealer, who determined that the engine was extremely low on oil even after a recent oil change but was unable to determine the cause of the failure. The vehicle was not repaired. After investigating the failure, the contact related the failure to NHTSA Campaign Number: 25V274000 (Engine and Engine Cooling), but the VIN was not included. The manufacturer was notified of the failure, a case was opened, and the contact was referred to the NHTSA Hotline for assistance. The failure mileage was 70,000.

Knocking coming from engine, seems like engine failure

The contact owns a 2021 GMC Yukon. The contact received notification of NHTSA Campaign Number: 25V274000 (ENGINE AND ENGINE COOLING); however, the part to do the recall repair was not yet available. The local dealer was contacted. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was made aware of the issue. The contact had not experienced a failure. VIN tool confirms parts not available.

Purchased certified used from Davis Chevrolet in 2023 with multi-point inspection. Had motor replaced due to engine lifter failure in July 24, 2024. Electronic fuel module failed June 22, 2025. I have had multiple issues in between including alternator, belt/pulley system, rear end issues costing thousands of dollars all while paying a large amount monthly. The vehicle is giving constant issues and is not safe.

Had the engine replaced at 10,342 and the engine just went out again at 85,343 Old engine #N1210061cu8x0090 replaced at 10,342 Faulty replacement engine #t2211729l92x0913 I show this engine is part of the recall from but GMC is telling me my engine isn’t part of this recall and won’t cover my faulty engine that just went out.

The engine and transmission shakes and they say all this normal. Vibration occurs throughout vehicle at idle or driving at any speed. Also, rpm hand slightly moves up and down while idling in park. The vibration is more prominent in 2 and 3 row seats. I have taken it in about 7 or 8 times for the same issue to 4 different dealerships. Only one has actually felt the issue and visually saw the vibration/hop in rear of vehicle. The technician could not determine the problem as GM only allowed a visual inspection. He was not allowed to take anything apart so I am still left with the issue and it is getting worse. In addition, vehicle taken to collision shop to inspect frame, vehicle was within spec. Vehicle is now back at another dealership to address the issue. The only thing that all the dealerships have done is road force balance tires, alignment, and changed out driveshaft axle from a prior recall. I paid to have to have a differential fluid change still has vibration. At this point, it is concerning because as I stated the problem is getting worse. Also, dealers are looking for a computerized answer and I dont think a powertrain issue will be diagnosed this way. My truck should be under recalls but none has applied to it.

The contact owns a 2021 GMC Yukon. The contact stated while driving 68 MPH, the vehicle stalled. There was no warning light illuminated. The contact was able to pull over to the shoulder of the road. The vehicle failed to restart and was pushed into a parking lot, where a mobile mechanic determined that the battery and the starter needed to be replaced. The parts were replaced; however, the failure persisted. The mechanic determined that the engine had seized. The vehicle was towed to Pruneda Auto Mechanic, where it was diagnosed that the engine had seized and needed to be replaced. The vehicle was not repaired. The contact related the failure to NHTSA Campaign Number: 25V274000 (Engine and Engine Cooling); however, the VIN was not included in the recall. The dealer and the manufacturer were not notified of the failure. The failure mileage was unknown.

On 05.29.25 my 2021 GMC Yukon Denali with 24,000 experienced engine issues and ultimately a total failure. While driving at 65 miles an hour the engine light began blinking and a thumping/knocking noise began on the front passenger side of the vehicle. I was 1 mile away from the GM dealership and went there immediately. They called me two hours later confirming the engine failure and that it would have to be replaced. They stated, however, the engine is experiencing a national backorder. No timeline has been provided for the engine to be received or replaced. I am curious to know if the new engine will come from the same engine group that is currently having issues, and if this can happen again.

The oil level reads way below from what the engine percentage tell me. The vehicle Oil consumption happens to fast. My last two oil changes have been within a month

The #3 lifter on my cars engine failed with 80101 miles on it. The engine started to run weak by shuttering. My wife was driving and the car was shaking at a stop and vibrated upon acceleration. I took the car to the dealer and they said the #3 lifter collapsed and could have caused engine failure. The dealer replaced the lifters on that side of the engine.

For whatever reason our 2021 GMC Yukon Denali is not listed in the current 2025 GMC motor recall including cams and lifters and accompanying parts. While driving our truck about a mile from the house the vehicle began seizing and shaking (almost as if we had blown several tires); we immediately pulled over and accessed. Called Dealership and had truck towed there immediately. We are told that it needs cams and lifters and that b/c our VIN does not pull up a recall that the repairs will cost ~$9800.
