  12/16/25 (evening): Warnings began cycling across the screen: 1) Service ESC, 2) Vehicle Leveling for Stability, 3) Rear Axel System Off, 4) Engine symbol began flashing, and 5) Service Traction Control. I felt vibration/bouncing while driving as well. 12/17/25 9 AM: Took 2021 GMC Yukon Denali to GMC dealership. They ran a computer scan and reported a misfire, but nothing else appeared to be wrong. They told me that sometimes a low battery can cause the warning lights and messages to cycle. They recommended that I keep driving it and return if the warnings appeared again. 12/17/25 9:18 AM: I left the dealership. I drove 4.5 miles, and all the same warning lights came back on. When I pulled into a parking lot, it smelled like my engine was on fire, and dark smoke was coming from my rear exhaust pipe. I called a flatbed tow truck and had the car returned to the dealership. Mileage: 52,285 GMC 2021Yukon Denali XL 6.2L V8 engine Well-maintained with regular oil changes. The dealership told me there was a lifter failure and that the engine could be damaged and would need to be replaced if the cam, pushrods, etc., were damaged. They also told me I was out of warranty by less than 60 days. The dealership said my warranty expired in October 2025, even though my vehicle is a 2021 with only 52,285 miles. They just informed me that the left lifter was replaced at 6,000 miles and that they will replace the right lifter. I am concerned about further damage down the road, given the recalls on the GMC 6.2L engines.

  While driving on a two lane road, my vehicle put itself into Neutral without me doing anything and the engine stopped. All things powered down. The engine stopped. not propulsion, nothing. I tried to pull over to edge of road. Car would not start - no activity. The vehicle had to be towed to the dealership. My safety was put at risk by my car simply stopping while driving down the road. The dealership has confirmed the engine needs to be replaced. There was no warning of engine problems or ANY indicators.

  On December 1, 2025 at around 5pm CST, my 2021 GMC Yukon XL started making a squeeling noise then stopped while driving down the road. It left me stranded in the middle of the road. A P0016 CODE was produced and the engine light came on. I had the vehicle towed the next day to Stew Hanses GMC in Clive, Iowa. The engine was torn down for inspection and was told the rod bearing went bad and it had low oil even though I was within the window since the last oil change and having documented all necessary required maintenance. I was told the engine needs to be replaced and am in the process currently of Stew Hanson GMC replacing all necessary parts. I was told I do not have a recall on the vehicles vin number by GMC corporate and the GMC dealer. It is coming up on a month since the incident happened and vehicle towed to dealership. I do not have pictures from the dealer yet or final invoice as this is still in process. I wanted to document this somewhere.

  Engine failure of lifters and piston rings at 58000 miles. Engine failure at highway speeds causing complete loss of power on highway. It is completely unacceptable to have such catastrophic engine failure on such a new vehicle.

• 12/19/2023· FORWARD COLLISION AVOIDANCE

  Driving down the interstate at 70mph and it randomly slams on the brakes. At about 45mph it let's loose and speeds back up. There's never anything in front of the car and it does it a few times a week. Usually throws everything on the floor that was on the seats and scares the hell out of anyone inside the vehicle. Waiting for it to do it with a semi behind us that can't stop as fast!

• 12/17/2025· POWER TRAIN

  While driving my 2021 GMC Yukon XL, the vehicle unexpectedly lost acceleration. After lifting off the gas pedal, it jolted forward, triggered a “Reduced Performance” dashboard warning, and remained in what felt like second gear, refusing to shift. I immediately pulled into a parking spot; when I attempted to reverse, the vehicle would not move backward. As you may imagine, this was a major safety concern, as I had my [XXX] and [XXX] children in the vehicle with me. I had the Yukon inspected at a GMC dealership, where a technician confirmed the issue originated from a faulty transmission valve body. My independent research has revealed this to be a widespread defect in the 2021 Yukon XL, prompting GM to issue Special CoverageXXX, which explicitly covers valve-body replacements for 2021 Yukon XLs experiencing reduced performance. Despite meeting these criteria and receiving identical diagnostic alerts, I was informed that my VIN is not covered. I am formally requesting that this safety-related defect—widespread among this model year—be recognized and my VIN included under Special Coverage XXX. The valve body causing the loss of propulsion in my Yukon XL is exactly the same defective component GM has acknowledged and is covering under this program.

  I was driving 30 mph when the car went into neutral and rolled to a stop. When I put on the brakes the engine shut off and it went into park. It would not restart or shift out of park . I was stuck in an active busy road. The car was towed to the dealer. They said it was a problem with the BCM. GMC had put out a bullletin which was to reprogram the BCM. My concern is that if this had happened on a busy interstate in traffic at highway speeds the results could have been fatal.

  GMC currently has bulletin out on the issue and how to fix it. unfortunately this doesn't not fix it and I am going to have to replace my whole rear differential at only 60,500 miles. Gmc is well aware of the situation and has not done a recall. The fix the bulletin proposes would not work and there was over and inch of metal shaving found. This is a huge issue in the specific vehicle and the part to replace the rear differential isn't even available (national backorder with no ETA) leaving customers without a vehicle or solution for their faulty issues. GMC should be liable for their negligence and putting customers in potential harm if the vehicle is continued to be driven with a failing rear differential. The vehicle did not prompt any warning messages but the grinding sound was very loud. Bulletin No.: 21-NA-028 Date: January, 2023

  Vehicle indicated that the suspension system was disabled. Vehicle then lost power and disabled itself driving through the Eisenhower Tunnel I-70 Colorado. This tunnel is over a mile and a half long. We called 911 as we were very worried we were going to have another vehicle crash into us as there are no breakdown lanes. The tunnel had to close to West Bound Interstate traffic and the vehicle had to be dragged up a tow truck because the back wheels were locked. The CDOT tow truck then dropped our vehicle outside the tunnel. We had a private tow company (again dragging the locked tires onto the next truck) take us home and to our personal repair shop. Vehicle was diagnosed as a blown engine. We then had to tow our vehicle, again dragging tires, to a GMC certified shop. We have spent $1502 on towing. This vehicle has approximately 57,000 miles and was 9 days out of the powertrain warranty. The repair shop has the same diagnoses and a dead battery because we could not turn the vehicle off. We have no vehicle to drive as ours sits at the repair shop waiting for parts. GM told me we were out of warranty and would not help. The dealership says GM may do cost sharing but will still cost us $2000.

  Our 2021 GMC Yukon XL for the third time now has shifted from Drive to Neutral and then turned off on us on the highway. The first time GM changed the motor (at approximately 35,000 miles), the second time was about a month ago we were at the White Mountains and it shut off on a highway, the third time was yesterday [XXX] (with 61,057 miles), my wife and I were driving on [XXX] in Massachusetts and when I accelerated the vehicle shifted from Drive to Neutral and then shut off on me. This vehicle is not safe and on all of these three occasions I have been lucky not to be hit and have been the driver. I am a trained and professional driver and I must state that this vehicle is not safe at all. I need to find a solution to this with General Motors.

  Routine oil change by professional local mechanic. Upon completion we were told that the vehicle would not turnover. The mechanic diagnosed and found that were 2 recalls for our vehicle - one for the fuel pump module and one for the engine. We had our vehicle towed to the local GM dealership. They then replaced the fuel control module. GM tried to manually crank over but engine seized once again. We spoke to the GM Advisor prior to this and were told that our vehicle was not part of the engine recall because our VIN was not listed as part of it even though our vehicle had the same exact issues as described in the engine recall and was for the exact year/make/model of the engine. The dealer quoted us $14,896 to replace the engine. They stated they would submit a Goodwill claim to GMC to help discount the cost to repair/replace the engine. The dealer called back later that day and said GMC would be willing to cover 30% of the cost so our expense would be around $10,000. All this for a vehicle we've only driven for less than a year and a half. The vehicle went in for a routine oil change and has never had any issues prior to this. This happened suddenly without any sort of warning. To make matters worse, our powertrain warranty expired a day or two before this occurred. We are still trying to fight with GMC to cover this engine failure. The car has less than 75,000 miles and is only used for basic personal needs like driving to school and the store so it is shocking that the engine would suddenly fail like this and to make matters, the manufacturer refuses to take responsibility for it and to cover it under the recall even though there has been known widespread issues with this engine.

  GM has consistently failed to deliver safe and reliable vehicles to the american public. I purchased a 2021 GMC Yukon Denali XL and the transmission needs to be replaced completely after the valve body was already replaced once. This issue proves to me that GM is not a reliable and trustworthy brand, with poor business ethics and a track record of having to be bailed out by our very own government for low quality vehicles. I am asking for the Federal department to investigate thoroughly and recall all transmissions that could negatively impact american families. These vehicles are not affordable for the average household and the quality of workmanship does not match the price point. Please find attached a document from GM directly that covers all recalls and previous repairs done to my vehicle. I am now fighting to get my down payment refunded as well as the payments that I have made on my vehicle.

  WITH ONLY 52 MILES (2-DAYS OLD), I WAS DRIVING HOME WHEN I HEARD A KNOCK. THEN THE ENGINE LIGHT CAME ON AND THE VEHICLE STABILITY CONTROL LOWERED THE VEHICLE AND THE VEHICLE SHUT OFF. I WAS LEFT IN THE MIDDLE OF TRAFFIC UNABLE TO MOVE THE VEHICLE TO A SAFE LOCATION. NEUTRAL WOULD NOT WORK EITHER. WHEN THE VEHICLE WAS TOWED TO THE GMC DEALERSHIP, THEY KNEW EXACTLY WHAT WAS WRONG WITH THE CAR, BROKEN SPRINGS IN THE ENGINE. APPARENTLY THEY SENT A NOTICE STATING THAT THE ENGINE SPRINGS WERE BREAKING AND NEEDED TO BE REPLACED. THE DEALERSHIP ONLY OFFERED TO REPLACE THE 2 BROKEN SPRINGS, NOT ALL OF THEM SINCE MY VEHICLE WAS BUILT AFTER THE DATE NOTED FOR HAVING ISSUES. THEY WOULD NOT PROVIDE ME WITH ANY PAPERWORK ABOUT THE SERVICE. I'M NOT SURE HOW THIS COMPANY CAN GET AWAY WITH SELLING VEHICLES THEY KNOW HAVE ISSUES WITH FAULTY PARTS.

  GM's 2021/2024 6.2 engine recall began with vehicle production March 1st, 2021. My Yukon XL Denali was produced Feb 26, 2021, THREE days before the recall start. The engine was replaced by GM approximately 6/21/2023 (previous owner), the replacement engine was built the 129th week of 2023. With my recent call to GM, they only reference the original vehicle's build date. If my vehicle missed that by three days, and now has another engine built during this recall period (2023), they have no help for me, it is NOT covered in this safety recall. Neither GM or my dealer has been able to tell me which oil to run 0w20 or 0w40. This vehicle's engine failed just outside of the current recall dates. With the expansion of dates, I can have my motor inspected and be covered under the extended year and milage warranty given to other owners. I am requesting NHTSA to expand the existing recall date. Thank you.

  Vehicle Information Make: GMC Model: Yukon XL Denali Year: 2021 VIN: [XXX] 1. What component or system failed or malfunctioned, and is it available for inspection upon request? The engine failed due to defective lifters and camshaft components, along with excessive oil consumption. These issues rendered the vehicle inoperable and required over $10,000 in repairs. The failed components are available for inspection upon request. 2. How was your safety or the safety of others put at risk? The engine failure occurred while the vehicle was in motion, creating a dangerous situation for my family and other drivers. Sudden loss of engine power could have led to a collision or left us stranded in unsafe conditions. 3. Has the problem been reproduced or confirmed by a dealer or independent service center? Yes. The issue was diagnosed and confirmed by DeFouw GMC in Lafayette, Indiana. GMC has acknowledged the defect and agreed to cover all but $2,000 of the repair costs. 4. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? The vehicle has been inspected by DeFouw GMC. GMC is aware of the issue under Case #[XXX]. No inspections have been conducted by police or insurance representatives. 5. Were there any warning lamps, messages, or other symptoms of the problem prior to the failure, and when did they first appear? No, it all happened at once. The vehicle was extremely well cared for, and GM has all of the oil change records. Additional Comments: We have been without our family vehicle since [XXX], and GMC has not provided an estimated arrival date for the replacement engine. We are now entering month four without a vehicle, which has severely impacted our family’s mobility and safety. This delay is unacceptable and reflects poorly on GMC’s commitment to customer safety and service. Has also cost us over $10,000 out of pocket, which I will seek reimbursement for legally, if I must.

  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.

  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.

  My 2021 GMC Yukon XL Denali is part of the April 2025 recall for the 6.2L V8 engine defect. The dealership confirmed the engine must be replaced, but the part is on backorder, potentially for several months. In the meantime, GMC only authorized a GMC Acadia as a courtesy vehicle. The Acadia is not comparable to our Yukon XL. We are a family of six, and while the Acadia has a third row, there is almost no cargo space with it in use. Our Yukon XL has over three times the cargo capacity, which is necessary for safely transporting luggage and sports equipment during our frequent trips (2–3 times per month). Because of this, we have already been forced to rent a larger SUV at our own expense for a recent trip. GMC’s Courtesy Transportation Program states that owners should receive comparable transportation during recall repairs. Despite escalating through the dealership, GMC Customer Assistance, and even the regional manager, we were denied a comparable loaner or guaranteed rental coverage. This leaves our family in an unsafe and impractical situation while waiting months for the recall repair.

  I was driving from New Orleans with my family when traveling at 75 mph when it’s like the transmission started straining and the engine was losing power/pressure it’s like the engine or transmission was struggling I’m not sure what was causing it but it was a scary experience knowing I’d my kids and my wife with me and we were out in the middle of nowhere.

  The OEM tires, Bridgestone ALENZA A/S 02 - SIZE: 275/50R22 hydroplane and have very poor wet traction. Why traveling at low speeds , under 40mph in moderate rain, the vehicle will owe control.

  GM is unable to remedy this recall. I have been waiting since April 2025 (when the recall was issued) to our family vehicle in to be corrected. This is a serious recall that GM is not taking serious, and this is our family car.
