Gmc Yukon 2021: Retiros, Quejas y Ley de Limón de California

My 2021 GMC Yukon AT4 with a 5.3L engine failed as I was driving down a highway going to my child's ballgame. It put me at risk of wrecking on the highway with other traffic around me as I needed to get my vehicle off the road way. Thankfully, I was able to get the vehicle to a safe spot to get it towed. After having the vehicle towed to my local GMC dealer, they determined my lifters in my engine failed and my camshaft had irreparable damage. GM has a lawsuit going on right now against their faulty lifters in their engines. The dealership told me they recalled the 6.2L engine, but not the others. It is shameful that they haven't recalled the other engines that also have the same lifters with the same active fuel management system. My power trained warranty has just expired and they want to charge me over 15,000 to replace the engine and radiator. I am now fighting with GM to help cover this expense that I feel a recall should take care of. These vehicles are not safe on the road with these faulty engine systems specifically the lifters inside them that are known to fail and GM is aware of this and not doing anything. Please help me and other GM owners get these vehicles recalled and make GM replace these engines at no cost to the owner due to their faulty engine components. My daughter and I could have been seriously been injured or died that day in the highway due to the abrupt engine failure on the highway going 70mph. Thank you for your time and God Bless.

Vehicle had lifter failure. This could’ve have caused a devastating accident to myself or family which includes my 8 year old daughter. GMC has knowledge of this problem with this motor

Motor started knocking My safety and my family safety was put at risk because we were driving down the street. The car is now at Woody dealership in Naperville, IL. Being inspected as we speak. No symptoms prior to failing.

Engine is misfiring. Took it into local mechanic who mentioned he has seen many similar issues and knew there was a recall for similar 2021 Yukon engine issues but for some reason this model was not included. He encouraged me to trade in the vehicle because most likely the engine would need to be replaced (or a $10,000 repair) and it was not save to continue to drive in this condition. I call GMC and they suggested I contact the NHTSA to request that this year and model be added to the recall listing for other similar Yukon engines.

I was driving on the highway, I-55 N just north of Bloomington. I was on cruise control and was coming up to a lane merge going into construction zone. I braked, moved over, turned off cruise control and noticed the engine was cut off and rpm’s dropped to 0. Luckily I was able to get to the shoulder before the highway merged with no shoulder in construction zone. I have the 6.2 L engine in the GMC and have been through propulsion test and 2 oil changes since the test. My engine failed during highway travel and I see on several threads this unfortunately is an unsafe situation others have been in. What are my options as I do not feel safe in a vehicle that will turn off unexpectedly on highway travel.

NHTSA #11732129

While operating my 2021 GMC Yukon AT4, my vehicle suddenly developed a popping noise, the check engine light began flashing, and the traction control warning illuminated. The vehicle lost power and had reduced acceleration, forcing me to pull off the road because it was unsafe to continue driving. This created a serious safety risk and appears consistent with reported GM lifter or engine defects.

Lifter failure.

NHTSA #11733832

Hello, I was driving on the highway with my family and my engine had a sudden loss of power. I only have 52,000 miles on the engine and it has been serviced the entire time. We almost got in a major accident as we had cars and trucks moving around us at a very high speed as we tried to pull over in the breakdown lane. I brought the car to Daddario GMC in Shelton, CT. They did a diagnostic test and said that cylinder 2 was misfiring. Upon closer inspection they saw that there was oil sitting on top of the piston head which indicates engine failure. I have since contacted GM warranty services given my car was just past the warranty date of November 2025, but still under the 60,000 miles of coverage. I did some research and have seen this is a very common with these engines as GM did a recall on 600,000 already. For some reason my VIN # is not listed on the current recall even though my engine is in the same year as the others that were. I would like GM to cover my engine 100% but was told they may only pay a % to fix it. Can you do anything to help me get them to cover the engine at 100%? I also wanted to let you know about this issue as my VIN was not under recall and this may happen to other people/families who have the same engine as mine that isn't recalled.

ngine seized (according to GMC dealership service department). I was driving 75mph down the highway and the car shut down. I noticed it losing power so I was able to get off at the exit ramp, but not in a safe location. The car shut completely down in the right lane at the stop sign. Approximately 7:50pm car broke down - stuck on the road until 10:22pm. Yes safety of myself and others were put at risk. We purchased the car 2 weeks ago with no signs of issues. Bought the car with 103,499 miles. The car had very well maintained service records as well at time of purchase. We towed the car to the GMC dealership and they said the engine is seized up. No warning lamps or messages at time of failure. I drove the car early that day and it was running fine. I do not have any documents to upload at this time. Since this all happened on Friday and we are just now getting the report back today (Tuesday).

My vehicle started making a weird noise and when I took it to the shop, they told me my crankshaft has gone bad and I was lucky I caught it before the entire engine blew

The engine has started using large quantities of oil. Not dripping oil, burning oil. I have been doing oil consumption studies with GMC for months now. It burned 7 quarts in 5,000 miles. The dealership tells me it is not part of the current recall on others with the same engine, make and model. It is doing the same thing as what the recall is for and my VIN number should be added to GMC’s recall list and the motor replaced. It is a serious safety issue for me and my children,

Loss of power while driving, no warnings, no lights on dash, no unusual noises, and no codes. The Yukon just randomly went into neutral while driving 65 mph and "Press Start Again" popped up on the dash. I struggled to get the truck to the side of the road safely. After getting the truck into park it started back up, and I was able to make it the 3 miles home. I scheduled it to go into the dealership as it still is making no noises, and had no engine light or codes, about 2 miles from my house it shut off again while driving, only this time when it restarted it now has a ticking sound coming from the engine however no warning lights and no codes being displayed. I am reporting this as I believe it falls under the open investigation EA25007, although it clearly is the same failures others have experienced on models that were included in the recall 25V-274. I am also attempting to contact GM as my vehicle is no longer under the powertrain warranty that was not extended for the vehicles that were not included in the recall.

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)

Engine is leaking alot of oil from crankshaft..I was informed there was a recall on the same type and years for the problem I am having but I do not have a recall on mine

NHTSA #11727698

I was driving down the highway at normal speeds under normal conditions and the engine light came on and started flashing. By the time I could find a safe place to pull over I heard the engine knocking. Left my wife, two young kids and myself stuck in the middle of the road with traffic coming. Managed to get it out of the road before going to get my truck and trailer to tow it home. I assume this is due to the L87 recall but mine was built in 01/21 and the recall is said to cover 03/21 and up. We don’t really know what to do at this point being its my wife and kids only way to work and school.

NHTSA Team, I am the current owner of a 2021 GMC Yukon Denali (VIN: [XXX] ) with the 6.2L L87 V8. At approximately 148,239 miles, I experienced a catastrophic lifter failure. My mechanic diagnosed a failed AFM lifter and metal contamination, requiring full engine replacement. This is documented under GM Case #XXX. CARFAX revealed that prior to my ownership, lifters were replaced twice (~10,469 miles and ~25,572 miles). The dealership I purchased from did not disclose these prior repairs, as they used an alternative vehicle history check. Only upon this third lifter failure did my mechanic identify this recurring defect. I submit this to NHTSA’s investigation into post-repair failures of the GM 6.2L engines. The pattern shows prior remedies were insufficient. Supporting documents (CARFAX, mechanic report) are available. Please advise if further details or inspection of the failed engine components are needed.

Driving the vehicle on the highway when I started to hear a ticking sound from the engine. After a few minutes, the check engine light came on and started flashing, traction control shut off and some system related to the rear end shut off. After inspection, it appears to have dropped a lifter.

On Christmas Day while driving on the highway, I noticed a ticking sound coming from the engine. Our 21 Yukon Denali just hit 85,000 miles. I first noticed the traction control light was became disabled and then the check engine light started flashing. The sound escalates when you step on the gas. It appears that the lifters and cams are damaged on the vehicle and had to be towed to a dealership were it currently waits to avoid further damage. I was advised by the dealership that this particular vehicle is not part of the engine, recall notice, but heard that they might be expanding vin numbers to the recall as more incidents occur. They did confirm that the lifters and Cam’s are the issue.The vehicle has had a great maintenance record and was just at the same dealership five weeks earlier for oil change.

I had the 25v-274 recall serviced at my GM Dealer and was never provide with any paperwork on the extended warranty that was part of the recall. as you can image, not having anything in writing is a big risk as these engines have been catastrophically failing. GM was supposed to provide a extended warranty and service manual update.

While driving on the and merging onto the highway, the check engine light and other alerts came on our 2021 GMC Yukon. There was a fluttering noise coming from the engine and the vehicle started to have decreased acceleration. We had to immediately exit the highway and park the vehicle. We then had to take our vehicle to our regular mechanic since GMC dealership was backed up and we needed the vehicle repaired. Our mechanic has identified the issue to be with the engine. The lifters in the engine broke which also damaged the cam shaft. This is a very costly repair. Our vehicle is four years old and out of warranty since we have 80k miles on our four year old Yukon. This problem with the GMC L84 5.3L V8 engines seems to be a common issue and other owners have posted their frustrations on various websites and there is currently no recall on this 5.3L engine. This is a safety issue and a recall should be issued like the one for the 6.2L engine. Why is there no recall for the 5.3L engine? A recall needs to be issued for the GMC L84 5.3L V8.

NHTSA #11730701

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.

NHTSA #11679754

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.

NHTSA #11678448

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.

My GMC Yukon with 6.2 is using 1 quart of oil every 1000 miles. An oil consumption test was performed and documented with the dealer. In addition there is now a very rough idle while at a stop. The date on the engine build is just months ahead of the current recall.

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 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.

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.

I took my vehicle into the GMC dealer near my home in Beaver Dam, Wisconsin (Napleton) on April 30, 2025 to have the L87 engine recall addressed. I had a video with sound where a loud clacking noise could be clearly heard, coming from the passenger side of the engine. The service attendant and the mechanic assigned to my vehicle listened to it and both agreed that the sound was not normal, or good. Four hours later, they called and said the vehicle was ready to be picked up. They did neither pass or fail the engine, and didn't put in thicker oil. I was told that they aren't doing anything until they received clearer direction from GM. This is very disappointing for me and now afraid to drive on the highway for fear of catstrophic failure and potential crash. I called another GMC dealer nearby, in Watertown, WI, who said they weren't doing anything either with the L87 engines (year 2021-2024) until they recieve clearer direction from GM. I have taken my vehicle in 2 previous times to address the "clacking" noise, each time they say they hear nothing wrong.

I am having an oil burning issue in my 2021 GMC Yukon Denali 6.2L engine and understand that some Yukon's have been recalled for this, but not all. GMC directed me here. My check engine light went on last week and when it was plugged in it showed critical oil life despite being well below my next scheduled oil change (which has also resulted in me having a Rejected state inspection sticker due to this being in the computer at time of inspection). I am concerned that not all Yukons have been recalled but I'm clearly having the same issue as others as this is only a 4 year old vehicle and otherwise in very good condition. This would be available for inspection by you at any time. Also, this issue has been confirmed with the dealer but my VIN is not part of the current recall. Is there a way to get this VIN added to the recall for further inspection/resolution at GM?

I started the 2021 Yukon Denali this morning and there was a slight squeaking noise coming from the front of the car. I began driving and the noise went away. I parked the car and completed an errand. I then started the car to return home and on the way it started making the noise but much louder. I pulled over and the car died and refused to start. GMC Roadside Assistance sent two different tow truck that were not able to tow the car. Tow Truck #1 - Flatbed truck. Car did not go in to neutral because it couldn't start so the driver said that he was unable to pull it up onto the flatbed. Tow Truck #2 - Tow truck w/ Dolly wheels. Driver said it was too heavy for his Dolly to tow the Denali. GMC Roadside Assistance then said that they're two trucks were unable to pickup the Denali and that I was on my own to call and get a tow truck and they would reimburse me. I am on the side of the road all morning not knowing what tow truck company nor what type of tow truck to ask for...... Denali still does not start and am now awaiting a local tow company to make the pickup. GMC Roadside Assistance was a total failure.

The vehicle was handed off to the dealer for a routine oil change and transmission flush. The dealer stated over the phone that during the engine's oil draining process, the tech noticed metal particulates in the oil. The oil was allowed to completely drain until no drips fell from the drain plug. The tech then filled the engine with new oil to the correct level. After the trans flush was complete, the tech took the vehicle for a test drive, during which they noticed strange engine noises. The tech then parked the vehicle in the garage bay, where the engine subsequently failed. What component or system failed or malfunctioned, and is it available for inspection upon request?: The dealer has not confirmed the exact cause of the failure, however it is expected to be because of a failed connecting rod bearing.

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 driving my vehicle at a speed of around 50 MPH when the vehicle had an sudden loss of power. The vehicle displayed press the start button while the vehicle was still moving with the motor off. I pressed the start button and the vehicle shifted to park and went to complete loss of power functions. The hazard lights would not work, the vehicle would not start or move out of park. The vehicle was stuck in the fast lane in park with no way of moving it or warning others with hazard lights. My daughter and I almost got hit by a semi due to the vehicle issues. I had to call 911 to get police there for safety concerns and a tow truck to take the vehicle back to the dealership. The tow truck couldn't get the vehicle out of park as well, so he had to drag my vehicle onto the tow truck. I have a 2021 Yukon Denali with the 6.2 engine. The dealership told me I need a new engine because of a known failure with the engine. They can't promise me replacing the engine will fix the issue. The vehicle has less then 60,000 miles on it. This engine issue put my life and my daughters life in danger. I had to carry my daughter across the highway because it was unsafe to stay in the vehicle. I can only imagine what could of happened if we were traveling at higher speeds with no way to exit the vehicle. The dealership told me it is going to be 3 to 4 months before I get my vehicle back and they can't promise the new engine won't do the same thing. This is a huge safety concern that GMC needs to address. I am stuck paying for a vehicle that puts my family in danger. Something needs to be done immediately. The dealership told me they have several Yukons in the shop with the same issue waiting for an engine replacement.

Was driving normal down interstate. Interstate has two barrie walls making it a two lane road with no shoulders. Car was almost rear ended 3 times while it was stopped in middle of interstate. Me, my husband, my [XXX] , [XXX] and [XXX] were all in the car. I had to jump out the car while it was still rolling to make sure my children made it to safety before someone didn’t see us and hit us at 70mph. We had to cross the road and jump over a barrier in the construction zone. It took our high way patrol 35 mins just to show up and shut the road down to get the vehicle moved. According to the GM mechanic, a rod went through the block causing a hole. There was no warning of this happening, the car made noise and the vehicle automatically said low oil pressure, shut vehicle off, then an instant pop and smoked everywhere. The motor is on back order and won’t be able to be replaced for over 6 months if that. We had just purchased the vehicle and the motor was blown not even 3 hours after owning it.

I was pulling out of my driveway when I noticed that my mailbox was blown open from a recent storm. I stopped and put it in reverse (well tried to) but the vehicle would not shift. Quickly I continued to drive to make a u-turn instead and at that point my vehicle would not drive normally. The rpms would not go up despite pressing the gas and the engine was reving very high.gm dealer said 700 to pull the transmission to determine the issue, but after my research I’m certain it’s the valve failure in the transmission just as it’s done the same to others. Why is this transmission not recalled, but the disel engines on the same model are? Seems as though it is a similar issue. I’m afraid to see what they will charge me as my vehicle has 76,000 miles and I’m told is outside warranty coverage.

NHTSA #11724498

I live in Alaska. It was -13f. We were out and about and when I tried to leave and back up, the vehicle would not go into reverse. If it hadn’t been for a passing motorist my daughter and I would have been stuck there overnight, in negative temps. I was able to drive it home, in limp mode. Come to find out, it is the valve body on the transmission. That in cold temps the valve body can fail. After some research I found that it is a KNOWN issue with these vehicles and there has even been a “Urgent-Distribute Immediately” Service Update regarding the problem. Urging dealerships to review the VIN’s they have in their possession for the issue. I had the vehicle towed to a shop, where they confirmed the problem was the transmission valve body. They were unable to perform the work as it takes a qualified technician to replace. So it got towed to the closest GMC dealership. They have had it for two weeks now. They confirmed that it is a known issue and there have been no recalls. But they did tell me I was “in luck” because they stock that item so we won’t have to wait for a part. Not only is it going to cost me $3500 to replace something that is a know issue with this vehicle, but it could have ended in tragedy if no one would have come along when we were stranded. I urge you to make this a recall on these vehicles.

NHTSA #11704122

While my wife was driving to pickup my son from school, the vehicle was stopped at a stoplight and the engine turned off approximately 1 mile after departing the house. After getting the vehicle towed to the dealership because it wouldn’t start, it was determined by the dealership that the engine was seized. The vehicle has 60,500 miles on it and is driven by a suburban woman and has always had all maintenance done at the dealership. The vehicle is parked in our driveway and there are no signs of oil leaks or anything else that would indicate a potential engine failure. This VIN was not recalled with the larger GMC 6.2L engine failure recall, however other 2021 model years were recalled. Recommend immediate expansion of recall due to the unforeseen engine failure while driving with no previous warning lights (oil or check engine) or other indications prior to seizing. This experience indicates that the initial recall was not sufficient enough to locate and identify all of the 6.2L engines affected by the poor quality control issues at GMC.

NHTSA #11692647

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.

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.

NHTSA #11671846

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.

Valve body failure 72000 miles and warranty ended at 60000

NHTSA #11659348

I have had major transmission failure in my 2021 GMC Yukon Denali (6.2L V8, 10-speed automatic). The vehicle has approximately 72,000 miles. Recently, a critical internal clip/retainer in the transmission broke loose, sending metal debris throughout the transmission. This catastrophic failure has rendered the vehicle undrivable and requires a complete transmission replacement. Unfortunately, the vehicle is just outside the powertrain warranty, yet I firmly believe this failure is due to a manufacturing/design defect – not normal wear and tear. I purchased this Yukon Denali as a premium, flagship SUV and have maintained it carefully. I expected the transmission to last well beyond 72k miles under normal use. It is disappointing and that a core component failed so early. Not only has this imposed a significant financial burden, but it also undermines my confidence in the vehicle’s safety and reliability for my family. A modern transmission should not self-destruct at this mileage, especially given GM’s reputation and the Denali’s top-of-the-line status. Importantly, I have discovered multiple known issues and GM bulletins related to the 10-speed automatic transmission used in my Yukon. For example, GM issued a major recall in late 2024 (NHTSA Campaign 24V797000, GM recall #N242454440) affecting 2021 Yukon models (among others) due to a defective transmission control valve that could fail and cause the rear wheels to lock up, this demonstrates that GM has acknowledged serious problems in the 10L80/MQC 10-speed transmission design. Additionally, a recent GM service bulletin (PIP6008C, Jan 24 2025) indicates that internal transmission retaining rings can dislodge, causing the internal gears to separate – which leads to loss of reverse and internal damage. This scenario is similar to what happened in my transmission. My family was left stranded away from home with no warning. The vehicle just stopped working. The warning lamp did not come on until diagnostics was run.

NHTSA #11657665

The car is by hard shifting. The dealership found, “THE TRANS TO HAVE A SHUDDER AND DEBRIS IN THE TRANS FLUID INDICATING TORQUE CONVERTER FAILURE RECOMMEND REPLACING TRANS DUE TO TORQUE CONVERTER FAILURE SENDING DEBRIS THROUGH THE PUMP AND VALVE BODY.” The first time we brought the vehicle into the dealership they just replaced the fluid and didn’t inspect for failures. The dealership now did and if the torque converter fails the car won’t drive, if I’m on the freeway that could cause a crash or worse.

NHTSA #11652675

Driving at normal speed when my 2021 Yukon backfired and began to lose power. The check engine light came on. The vehicle would go into reverse and would not get over 20 miles an hour. It has been at a GM repair shop since March 24th waiting on the tranmission valve body. There is no ETA from General Motors on when this part will be available. Could this be associated with the most recent GMC recall of 2021-2024 Cadillac, Chevrolet and GMC vehicles?

NHTSA #11657840

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

NHTSA #11686249

Knocking coming from engine, seems like engine failure

NHTSA #11670400

The engine needs replaced and GM doesn't have any engines or know when we will get any engines. Evidently this affects numerous 6.2 liter engines that GM made from 2021-2024.

My 2021 GMC Yukon Denali is affected by NHTSA Recall #25V-274. The recall notice states that defects in the engine’s connecting rod and/or crankshaft can cause engine damage and failure, resulting in sudden loss of propulsion and increasing crash risk. The recall status for my vehicle is currently listed as “Incomplete – Remedy Not Available.” My dealership confirmed that no repair is available and further told me that GMC will not authorize a buyback, trade-in, or loaner vehicle until a remedy is developed. This has left me with an unsafe vehicle that cannot be repaired, yet I am still obligated to make monthly payments. This defect creates a serious crash risk because the engine may fail and the vehicle could lose all propulsion without warning. My family is forced to either risk driving a defective vehicle or go without reliable transportation. Dealer Interaction •Dealer confirmed that the recall is active but has no available remedy. •Dealer stated GMC will not authorize a buyback, trade-in, or loaner vehicle until the recall repair is developed. •I am effectively stranded with an unsafe vehicle and no safe options. Remedy I am requesting that GMC be required to: 1.Buy back my vehicle under federal recall and warranty obligations; or 2.Provide a safe, comparable loaner or replacement vehicle at no cost until the defect is remedied. If a loaner is provided, I will continue making my monthly payments on my Yukon Denali.

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.
