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.

Low engine oil message keeps flashing after less than 2,000 miles of driver. Excessive oil consumption. Took vehicle to GMC dealership and it was confirmed that an engine replacement or replacement of the pistons and rings is necessary. Only 77,000 miles on the vehicle. My car is currently not a part of the massive recall.

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.

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.

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.

Lifter failure with cylinder #6. Car violently shook prior to this failure. No engine lights or messages until the next day when tried to drive. Ended up towing car to dealer. Car had 76k miles on it. Recall on 6.2L, but not on the 5.3L which is not immune to this same issue as the 6.2L engine.

Dec 28, 2025

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.

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.

The Yukon has stopped while driving twice. The check engine light came on, the dealership says there is an oil problem and the oil pump is bad along with bad lifters. There is wear to the motor as well.

Aug 13, 2025

My lifters collapsed and camshaft got damaged AND my cylinder in the bottom of my engine failed also. I know there is a recall for engine failure on the exact year make and model as my vehicle, the only difference is the liter engine. Mine and my 3 children’s safety were all put at risk when we were left stranded on the side of the road 6 hours from home The problem was inspected by GMC themselves and the tech admitted to this being a big problem with motors like mine yet they are offering ZERO help to make it right with me because my liter engine isn’t on the recall list even though many are acknowledging its happening with the 5.3 liter engines as well. My engine has failed as part of GMCs negligence. There were absolutely zero warning signs prior to this happening

POWER TRAIN

9 complaints

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.

Transmission issue - 2021 Yukon XL broke down 5/6/25 while driving with 2 of our children in the vehicle. the RPMs skyrocketed but the vehicle wouldn't go. was hard shifting and speed would not exceed 35ish MPH. message popped up on vehicle that said acceleration throttled and engine light came on. Took it to dealership and it is a known problem. Transmission needs a valve body replacement. This part is on national backorder for months. Spoke with the dealership on 6/5/25 and they still do not have an ETA. They ordered one on 3/19/25 that still has not arrived. I received a case number from GM but they are extremely unhelpful.

Jun 05, 2025

Vehicle would not go in Reverse. Rear tires locked up. When I went forward an error came up "Reduce acceleration" and went into limp mode while driving down the highway and shifted hard and almost caused an accident. Bought into dealer and they found that it needs a valve body assembly Part which is on backorder with no ETA. Currently been waiting for a month and still no ETA on Part. This should be a recall for 5.3L 10 speed. .

I was driving with my [XXX] son and my car just stalled out in the middle of the road. I couldn’t start it and we were stuck in the middle of the road. My husband arranged for a tow and the repair shop (safe auto repair Mont Belvieu) told me that this type of thing they have seen a lot of. The fuel pump power control module needed to be repaired and they said when that happens it sometimes shorts out the fuel pump system too. They said they had to repair 4 like this already during the week. My neighbor said the exact same thing happened to her friend gmc at4 a month ago and was also driving and the car just stopped.

1. Fuel pump power control module Code #P129F 2. Sudden stalling of engine at potential high speeds/ dense traffic areas. This created a major safety hazard for a potential FATAL accident. 3. It has been currently confirmed by the dealer Gerry Lane Buick GMC after initial the breakdown it was sent there for investigation. 4. No, It has only been inspected at the dealership in Gerry Lane Buick GMC in Baton Rouge Louisiana. 5. NO warning lamps or symptoms before COMPLETE and INSTANT vehicle failure at NIGHT on 10/1/2023. Additional Information: Please see NHTSA Recall #N212332040 After our own investigation we have found a recall report for the same year make and model for the same issue of the fuel pump power control module. Our VIN was not included in this recall but has the exact issue and year as the recall. This is very dangerous to have these vehicles driving around without the owners knowledge of the potential FATAL Danger.

Oct 05, 2023

Vehicle without any warning quit running, had to be towed, 19,400 miles on vehicle. could have had a wreck since I was on a heavily traveled 4 lane highway. Dealer Heyward Allen in Athens Ga. determined that it was the fuel pump and is on national backorder. This would tell me that there are other vehicles with this issue. There was another recall for these types of vehicles that could have also included this one N212332040. GMC could not answer why my vehicle was not included in the recall. GMC has of today done nothing about this issue except to say that the NHTSA issued recalls and they did not. Would not even take responsibility for manufacturing the part.

I was driving home from a long trip and heard a large pop. Several warning signs and messages began popping up and the vehicle was shaking and struggling to maintain speed. I was able to get home and get my family out of the vehicle and get it to a dealer down the road. They stated the Fuel injector and harness had failed.

Jun 27, 2025

Noticeable ticking from the motor, loss of power while driving and smoking. Took to dealership to for repairs. Lifters replaced on one side, within 30 miles after leaving dealership vehicle lost power and would not crank. Per dealership same issue with spun bearing and crankshaft. New lifters and crankshaft placed. While driving 3 weeks later vehicle shifted into neutral and lost power and hand to coast to side of the road. Replace battery and still would not crank, had to be jumped off and able to drive home. 3 codes were retrieved from reader.

I was driving on a highway at speeds of 65 mph and the engine stalled on the left lane. I almost got struck by a tracker trailer. The dealer supposedly fixed the issue and a few months went by and the vehicle died again engine failure in middle of the highway.

Apr 26, 2025

I was driving on a normal local highway and my car started to slow and an indicator to 'press start' to restart the engine came up. I tried to do that and the engine wouldn't turn over. My car sputtered to a stop during rush hour traffic as I was able to drift over to side of the road. The car wouldn't start after that, waiting for 10-20 minutes and re-trying wouldn't work either. I had to have it towed and am now awaiting a fuel pump module that is on back order. No warnings to me that it would happen and I fear that this could have happened on the highway at high speeds, causing a crash. My car is a large SUV that takes a lot to stop, the car just sputtering and dying is unacceptable. I see my car wasn't included in the recall of this issue back in 2021, but I believe it was manufactured during the impacted window and I took deliver in May of 2021 of the new car. I think more cars should be recalled to prevent this from happening to other people. Very scary when it happens and the alternative situations it can happen in, especially for such a large vehicle that typically is carrying multiple passengers.

Jan 16, 2024

I was traveling on the highway and the vehicle started to jolt, sputter and speed acceleration was reduced in a highly congested area with little room to maneuver. I had to quickly shift lanes and get off at the first exit I could as I figure out what the issue was. I immediately contacted my Dealership and they were able to get me an emergency appointment so my vehicle could be inspected that day. After the Dealers analysis they said that a lifter needed to be replaced. I have a brand new vehicle with less than 8,611 miles on it. The lifter issue puzzled me so I went to the GMC Yukon message and sure enough there are ALOT of 2021 Yukon/Tahoe owners that have had this exact same issue with even worse stories than mine.

The contact owned a 2021 GMC Yukon XL. The contact stated that while driving 70 MPH, the “Service Safety Restraint Device” warning light illuminated. A dealer was contacted. The vehicle was taken to a dealer, and the contact was informed that the air bag was not repaired correctly because there was electrical tape and packing foam inside the air bag housing. The air bag was replaced and the front driver seat belt was replaced, and the vehicle was repaired. The manufacturer was notified of the failure and opened a case. The approximate failure mileage was 117,000.

Sep 25, 2025

The vehicle has 22,000 miles on it and is under warranty. The airbag light indicating a malfunction stays on. The vehicle has been to the dealer 2 different times. The dealer indicates the factory(GMC) is working on the problem but has no solution at this time. Researching I have found this to be a problem for years not just the 2021 model. I have asked the questions: do my airbags still work in a collision? Can the airbags inflate by mistake? I’m a grandfather and have young children in the car. Are they safe? No one will give me a firm answer. Know what if I want to sell the vehicle? Can’t do it? Someone needs to make GMC accountable. Peoples lives are at risk with this issue.

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!

Dec 19, 2023

On Wednesday, January 12, 2022, while driving from Columbia, SC to Cincinnati, we were heading northwest through the mountains of North Carolina, on I-40, just east of the TN border. Traffic was fairly steady and heavy, so we were traveling at approximately 45 MPH, in the right lane, winding through the mountains. Our friend, ** ***** was driving, my wife, ********* *****, was sitting in the right front passenger seat, working on her laptop, and I was sitting immediately behind her, also working on my laptop. With a semi-trailer truck slowing ahead of us, *** signaled to make a lane change into the left lane (this is only a two lane highway). As we were transitioning to the left lane, the vehicle suddenly – without any warning or driver inputs – slammed on its brakes, bringing the truck to a sudden and violent stop. Given the violent halting of the truck, we all assumed we had been rear-ended by a truck. The braking was so serious, luggage from the rear of the vehicle shot forward like a missile, striking my wife in the back of the head. She suffered what we believe to be a concussion, and she did seek medical attention in the days following the incident. Sitting behind her, the sudden stopping action caused me to twist my left knee, resulting in what might be a cartilage tear. I also saw my physician in the days following, and he acknowledged the swelling of the left knee. He advised me to monitor the knee carefully, and if the pain persists, to get an MRI. The pain has not gone away, and I plan to get an MRI in the next week or so. Our friend suffered a severely strained back in the incident, and has been treating his back with both ice and heat therapy. This was the THIRD time this happened, each nearly resulting in a tragic accident. The dealer said "it's just a software glitch." The "Brake Assist" program is clearly defective and unsafe.

Dec 09, 2025

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 am writing to express my concern regarding a serious issue with my 2021 GMC Yukon. Recently, while driving, I experienced a sudden surge in power. About five minutes later, when attempting to shift into reverse, the vehicle would not respond. I tried multiple times with no success. Afterward, while driving it briefly around the block, it made a clunking sound, which raised further concern. Ultimately, I had to call a tow truck, and the vehicle was taken to George Gee GMC in Liberty Lake, Washington. Unfortunately, the next day the dealership was unable to duplicate the issue. There were no warning messages on the screen at the time of the incident, and no diagnostic codes were found, so they could not move forward with any repair. I later discovered that this exact issue is addressed in Technical Service Bulletin N242454441-02. However, I was informed that my VIN is not included in the special coverage, despite my vehicle being the same year and equipped with the same transmission mentioned in the bulletin. I am deeply concerned that this problem could happen again—possibly while I am driving in Canada, transporting my children, or in a location where calling a tow truck would be very difficult. My safety and my family’s safety are at risk, and frankly, I am now anxious about driving a vehicle I used to trust. I also have an extended warranty, but when I contacted GM service, I was told that unless the problem can be duplicated, it would not be covered. This is extremely frustrating given the severity of the issue and the fact that it is already documented in an official bulletin. I am requesting that this situation be escalated. I would appreciate any additional support, coverage, or guidance GM can offer to help ensure this issue is resolved and does not put me or my family at risk again.

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 HAS BEEN AT THE DEALER WITH GM INVOLVEMENT STARTING JANUARY 6TH AND IT HAS BEEN OUT OF THE REPAIR FACILITY FOR LESS THAN 2 WEEKS UP TO TODAY, 4/1/2021. THE VEHICLE HAS AN ADAPTIVE SUSPENSION SYSTEM THAT HAS NOT ONLY FAILED, BUT HAS CONTINUED TO FAIL AFTER MULTIPLE REPAIR ATTEMPTS. THERE SEEMS TO BE AN ISSUE WITH THIS NEW ADAPTIVE SUSPENSION, SPECIFICALLY WHEN THE 'VEHICLE ACCESS' OPTION IS TOGGLED IN THE SETTINGS. THIS HAS CAUSED MULTIPLE SAFETY WARNINGS; 'VEHICLE TOO HIGH, DRIVE SLOWLY VEHICLE UNSAFE' AND 'VEHICLE TOO LOW, DRIVE SLOWLY, VEHICLE UNSAFE'. DEALER AND GM HAVE REPLACES MILLIE PARTS, SOFTWARE AND SENSORS, TO NO AVAIL. THE MAJOR CONCERN IS THAT MOST OWNERS DON'T REALIZE THE RISK AND THIS IS A FLAW IN THE DESIGN WHICH COULD LEAD TO ACCIDENTS. MY VEHICLE HAD TO BE TOWED IN AT THE LAST RESURGENCE BECAUSE IT WAS NOT IN AS STATE TO BE DRIVEN. THE SUSPENSION COLLAPSED AFTER HAVING 35 DAYS IN THE SHOP. IT SEEMS THAT THE SOFTWARE AND THE SYSTEM AREN'T PROPERLY FUNCTIONING/DESIGNED. THIS COULD BE ENDEMIC IN EVERY DENALI, OR OTHER GM VEHICLE WITH THIS SYSTEM, THAT ENABLES THE AUTOMOTIVE ACCESS (VEHICLE LOWERS WHEN IN PARK). THIS ISSUE OCCURRED WHILE PARKED AND WHILE DRIVING, BOTH LOCALLY AND HIGHWAY. THE SCARIEST WAS WHEN I WAS DRIVING TO THE DEALER AND THE SUSPENSION STARTED BOUNCING CAUSING ME TO GO NO MORE THAN 40MPH ON THE INTERSTATE TO THE DEALER.

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.

Subject: Formal Complaint – Engine Failure in 2021 GMC Yukon Denali XL VIN: [XXX] Defect Number (GM): [XXX] GM Case Numbers: [XXX] / [XXX] / [XXX] Dear NHTSA Office of Defects Investigation, I am writing to formally report a critical mechanical failure in my 2021 GMC Yukon Denali XL, which resulted in a complete engine failure, rendering the vehicle inoperable and exposing my family to significant safety and financial risks. Despite following the recommended maintenance schedule and driving under normal conditions, the engine failed prematurely. The vehicle has been out of service for over four months, and I have yet to receive a definitive resolution or timeline from General Motors. I have incurred over $13,000 in out-of-pocket costs, including towing, repair estimates, rental vehicles, and continued loan payments on a non-functional vehicle. Key Details: Vehicle: 2021 GMC Yukon Denali XL VIN: [XXX] Failure Type: Total engine failure requiring full rebuild or replacement Time Out of Service: 4+ months and ongoing Financial Impact: $13,335.58 in documented costs GM Defect Number: [XXX] (noted internally by GM) Dealer(s) Involved: Midas Auto Service, Beaman GMC (Nashville, TN) I have made repeated efforts to escalate this through GM’s Case Advisors and Executive Team, but have received no meaningful resolution or written acknowledgment of my request for either reimbursement or a good faith vehicle buyback. Given the safety implications of such a catastrophic failure in a relatively new vehicle, I believe this may represent a broader manufacturing defect or quality control issue and warrants NHTSA investigation. I respectfully request that NHTSA: Log this complaint into your safety database Investigate whether similar failures have occurred in other 2021 Yukon Denali XL vehicles Contact GM for further information regarding this defect and associated safety risk Thank you for your attention to this matter.

I am the owner of a 2021 GMC Yukon Denali with the 6.2L V8 engine (VIN: [XXX] ). This vehicle has exhibited multiple serious issues affecting safety, drivability, and reliability. 1. Engine Noise & Oil Consumption: Since purchase, the vehicle has had a persistent loud knocking/tapping sound, especially under acceleration. The engine also consumes an excessive amount of oil between scheduled oil changes, with no visible leaks. I reported this to the dealership multiple times, but since there is no active recall or TSB, they refused to diagnose or repair the issue under warranty. I have since learned that many other 2021 Yukon Denali owners with the same 6.2L engine are experiencing similar issues and some have had repairs or engine replacements covered by GM. I have received no such support. 2. Braking Problems: The vehicle has ongoing brake performance issues. Despite replacing the brake components multiple times, the brakes feel inconsistent and unsafe, especially during highway driving or sudden stops. There is vibration and uneven response, and the braking system does not inspire confidence. These problems have persisted despite attempts to correct them. 3. Suspension/Handling Concerns: The suspension feels unstable and loose, especially at highway speeds or when turning. The ride quality is poor, and there is noticeable sway and body roll, which creates discomfort and concern for vehicle control. 4. Fuel/Propulsion System: The engine does not always respond smoothly to throttle input. I’ve noticed occasional hesitation or surging, which may be related to the previously mentioned oil consumption or fuel delivery. Again, the dealership has been unable or unwilling to resolve these issues without charging diagnostic fees. I’ve reported these issues to my local GMC dealer on multiple occasions, but no lasting solution has been provided, and I have not been able to afford expensive diagnostic costs out of pocket—especially for a vehicle of this price INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

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.

On [XXX] I brought my vehicle to Rivard Buick GMC with a squeaking noise that was check and attempted to be repair four times at the same location. They provided a quote for $2,309.10 stating it was the Master Cylinder. Rick the Services director said it was not cover under warranty and it need it to be cover by me, at that point I explain to him the vehicle has been in and out of his services department for the same issue since it had 20,000 miles. 1st time-They replaced the front brake pad stating GM had a defect on them (Noise went away for a few thousand miles) 2nd time- They apply conditioner to the brake and lubricant so they say (noise went away for a few thousand miles) 3rd time- They said it was not the front brakes anymore making the noise. They said warranty did not cover rear brakes due to GM not flagging it as defected pad. I complained the noise was coming from the front of the vehicle but they insisted it was the rear so I paid $500 plus to get the rear brakes at 60% life left on them. At the time of picking up the vehicle after repair completed the noise came back within a few miles from the dealer. I returned to the dealer and spoke with the Services Manager Troy, he apologized for the inconvenience and said they will take care the front brake at no cost to me, however they submitted a claim to GM to get the work done and kept my money when they misdiagnosed the issue. 4th time- Noise comes back at this point the warranty it's expired and they tell me it's the master cylinder the actual issue. When I talked to Rick, he said that GM was willing to pay for half of the work and the other half it's my responsibility. On [XXX], my wife and three kids almost hit a wall while trying to stop and the braked did not work. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The vehicle had a total failure of its rear safety package which includes blind spot monitoring, rear cross traffic alert, rear parking sensors and rear safety alert. The warning illuminated on the dash that all of these functions were offline and service was needed. We took the Yukon to a GM dealer and they replaced a computer and had a hard time getting it to program. This failure also affected the HVAC system in the car, with the fan staying on high. After 23 days of service, the dealer thought they fixed it. After two weeks of having the vehicle back the same alert came on 5-6 times in the same day, with another safety package failure. Now the alert doesn’t come on but none of those safety features work, they are all offline. It is bad enough driving a 20’ long vehicle without the safety package working, but now it is worse in that the car doesn’t alert you to the fact it isn’t working and you might not remember that it is defective. This could cause a collision on the highway or result in the driver backing into something or someone, relying on this technology.

I'VE OWNED OVER A DOZEN GM TRUCKS OVER THE LAST 20+ YEARS AND THIS MODEL IS THE WORST EVER! MY COMPLAINT: GM TOOK AWAY THE TURN SIGNAL LIGHTS ON THE SIDE MIRRORS. THE TURN SIGNAL INDICATORS ON THE DASH ARE TOO SMALL AND LOCATED WITH MANY OTHER LIGHTS/INDICATORS, SO THEY CANNOT BE SEEN QUICKLY NOR 'EASILY' AND CAN'T BE HEARD UNDER NORMAL TRAFFIC CONDITIONS. THIS CREATES AN INCREDIBLY DANGEROUS SITUATION WITH DRIVER DISTRACTION TRYING TO SEE IF A TURN SIGNAL HAS BEEN ACTIVATED AND INCREASES THE RISK OF VEHICLES NEXT TO THE TRUCK NOT EXPECTING A LANE CHANGE IF THEY ARE AHEAD OF THE TAIL LIGHTS. NUMEROUS TIMES OVER THE PAST FEW WEEKS I'VE OWNED THIS VEHICLE, I'VE ALMOST RUN INTO ADJACENT VEHICLES I COULDN'T 'SEE' BECAUSE THE BLIND SPOT WARNING SYSTEM DOES NOT DETECT VEHICLES WELL ENOUGH TO AVOID TURNING INTO THEM AND ALSO BECAUSE I WAS DISTRACTED TRYING TO SEE THE TURN INDICATOR ON THE DASHBOARD, OOK INTO THE SIDE MIRRORS AND WATCH MY DISTANCE TO CARS IN FRONT OF ME. THE TURN SIGNAL INDICATORS ON THE MIRRORS ON THE PRIOR MODEL SIGNIFICANTLY REDUCED DRIVER DISTRACTIONS AND INCREASED SAFETY TO THE DRIVER, PASSENGERS AND ADJACENT VEHICLES. GM MUST BE HELD ACCOUNTABLE FOR REMOVING SAFETY FEATURES! THEY MUST BE FORCED TO REPLACE THE MIRRORS WITH ONES THAT HAVE TURN SIGNAL INDICATORS IN THEM LIKE ON PRIOR MODEL YEARS. IF IT'S NOT A SAFETY ISSUE, WHY DID THEY HAVE THE INDICATORS IN THE MIRRORS BEFORE?? REMOVING THE MIRROR SIGNAL LIGHTS WAS OBVIOUSLY A SICK WAY FOR GM TO SAVE A FEW DOLLARS WITH INTENDED DISREGARD FOR THE SAFETY OF IT'S OWNERS, PASSENGERS AND EVERYONE ELSE ON THE ROAD. THESE PROBLEMS EXIST WHEN THE VEHICLE IS STOPPED (BLIND SPOT ISSUES), TURNING, CHANGING LANES AND MOVING ON EVERY TYPE OF ROADWAY, BUT ESPECIALLY AT HIGHWAY SPEEDS WHERE HUNDREDS OF FEET ARE TRAVELED IN ONLY A FEW SECONDS, AND DISTRACTIONS BECOME EVEN MORE UNSAFE AND DANGEROUS TO EVERYONE.

GM CHANGED THE TRAVEL OF THE STEERING COLUMN SO NOW IT'S ONLY A FEW INCHES FROM THE DASHBOARD. IN PRIOR MODELS, THE STEERING WHEEL (SW) TRAVEL WAS MUCH MORE. DUE TO GM'S DESIRE TO SAVE MONEY AND COMPLETE DISREGARD FOR DRIVER, PASSENGER AND OTHER VEHICLES SAFETY, THE DRIVER HAS TO REACH OUT TO THE SW RESULTING AT DANGEROUS ELBOW ANGLES. IN PERFORMANCE CARS, THE SW IS DESIGNED TO BE CLOSE TO THE DRIVER BECAUSE PHYSICS PRINCIPLES OF TORQUE REVEAL: THE GREATER THE ANGLE OF REACH, THE MORE TORQUE IT REQUIRES TO TURN THE SW. SO REACHING OUT WITH THE ELBOW AT ZERO TO 10 DEGREES REQUIRES A MUCH LONGER REACH, THUS GREATER FORCE/TORQUE AND LONGER REACTION TIME, THAN HAVING THE SW AT A 30-40 DEGREE 'ELBOW BEND'. THE POINT IS, FOR A DRIVER TO TURN THE SW ON THIS VEHICLE, IT TAKES TOO MUCH STRENGTH AND TOO LONG A REACTION TIME TO SAFELY OPERATE IT. I DO NOT FEEL SAFE DRIVING THIS MODEL LIKE I DID WITH PRIOR MODEL YEARS. WITH THIS 'LAND YACHT' HAVING AN EVEN LONGER WHEELBASE THAN BEFORE, THE DISTANCE TO THE SW IS EVEN MORE CRITICAL IN REGARDS TO REACTION TIME AND SAFE DRIVING! PLUS, SINCE THE SW IS SO CLOSE TO THE DASHBOARD, WHEN I RAISE MY LEG TO STEP ON THE BRAKE PEDAL (WHICH NOW I HAVE TO DO BECAUSE GM ALSO TOOK AWAY THE FOOT PEDAL ADJUSTER!), MY LEG HITS THE BOTTOM OF THE SW! THE TIME IT NOW TAKES TO BRING A FOOT UP OVER THE BRAKE PEDAL, TO LOOK DOWN TO SEE IF YOUR LEG IS GOING TO HIT THE SW AND CAUSE THE SW TO EITHER STOP MOVING OR RE-DIRECT THE VEHICLE INTO AN UNPLANNED DIRECTION, ALL WHILE TRYING TO STOP THIS OVER 7,700 LB VEHICLE WITH MUSHIER BRAKES THAN ANY MODEL EVER, IS DANGEROUSLY LONG. THE OVERALL REACTION TIME TO GENERALLY STOP THIS MODEL IS AT LEAST 5 TIMES THAT OF MY 2018 YUKON XL DENALI. THE TRAVEL LENGTH OF THE SW NEEDS TO BE INCREASED 2-3 INCHES TO SAFELY OPERATE THIS TRUCK. GM MUST BE HELD ACCOUNTABLE FOR INCREASING DANGEROUS SITUATIONS WITH THEIR VEHICLES!
