Gmc Yukon 2023: Retiros, Quejas y Ley de Limón de California

The contact owns a 2023 GMC Yukon. The contact stated that while driving approximately 70-72 MPH, the vehicle lost automotive power, and the engine seized. The engine warning light was illuminated. The vehicle was towed to the local dealer but was not diagnosed or repaired. The manufacturer was not contacted. The failure mileage was approximately 45,504.

NHTSA #11733503

On April 7, 2026, I was driving my 2023 GMC Yukon Denali Ultimate on the interstate at approximately 70 mph, accelerating to pass a car so I could get off on my exit. Without warning, the dashboard displayed "Engine shut off, press start button" and the engine lost power. I coasted off the interstate to the shoulder safely. I was alone in the vehicle. I thought it was a battery issue and had a coworker attempt a jump. The vehicle would not restart. I called Moses GMC of Huntington, WV, and they dispatched a tow through GMC Roadside Assistance. I waited approximately 2 hours on the shoulder for the tow. After the tow, Pete, the Moses GMC service manager, called and said nothing was wrong with the vehicle, that it only needed an oil change. He said it started right up and he drove it into the bay. Moses performed the oil change. When the technician test drove it afterward, the engine fully shut down on the hill leaving the dealership property. My husband Zach happened to drive past and saw the Yukon stopped with hazard lights on at the top of the exit. Pete called that evening and said, "I think there actually is something wrong with it." On April 10, 2026, Pete confirmed the failure is the GM 6.2L V8 L87 engine defect covered under NHTSA Recall 25V-274 (connecting rod/crankshaft manufacturing defect). Full engine replacement required, estimated 6-7 weeks. This vehicle was previously inspected by Moses GMC under Recall 25V-274 in August 2025 and cleared at that time, approximately 8 months before the April 7 shutdown. Vehicle had ~38,000 miles, garage kept, full maintenance records, no prior engine issues or warning signs. No crash, no injury, no other vehicles involved in any of the three failure events.

NHTSA #11733280

My engine has metal flake in it and once which is a sign of engine failure. I reported it to GM they said it was a normal amount and to keep an eye on it the next day toil change. They issued a recall on the 6.2L motors and they have not on the 5.3L motors and this one is doing the same thing. I want to get ahead of the ball before my engine give out on the highway but GM is treating it like it’s not a big deal.

Months ago I took my car to the dealer for the engine failure recall and they said there were no issues and changed the oil to a higher viscosity oil. Today I was driving and my engine failed while turning onto a busy road and took multiple tries to get started. It finally started and the engine light was flashing. The dealer told me th flashing engine light was bad and to not drive at all. I pulled over and had it towed to the dealer. The engine light stopped flashing. The dealer said they pulled a code on the computer and would look at it. They had my car for a full day so far and have said they can't find an issue. I do not feel safe having my family in this car when the engine can fail and they say nothing is wrong. I am lucky that I wasn't hit at the location it failed at.

Loss of propulsion due to engine failure after recall repair completed.

NHTSA #11732401

Was driving approximately 70 miles per hour on the highway. While driving the vehicle just stopped in the middle of the highway after going 70 miles per hour. Was unable to put car in park. Car just shut off. Four police cars had to surround car due to being stuck in the middle of the highway with my small child in the car. Took an hour to get a tow truck. Being told our engine is now completely shot.

NHTSA #11726597

While my husband was driving me and our 2 kids getting off of the highway, we experienced catastrophic engine failure. The engine just shut off with NO warning. It went in to Neutral and then park and shut off and would not turn back on. We were stranded on the side of the road in the dark while it was raining. We waited on an active roadway for 1 hour for a tow to come. It was towed to the dealership. The dealership reported that the engine is blown and that they ordered a replacement. I have a case open with GM who has confirmed the engine replacement is under warranty but what is to say this won’t happen again with the new engine ? The vehicle is not safe.

NHTSA #11734687

On September 4, 2025, I brought my 2023 GMC Yukon Denali in for the product safety recall regarding the engine. My engine passed the recall inspection and I was given an oil change with high grade synthetic oil. This past Saturday, March 7, 2026 as I was driving in Tampa Florida with my [XXX] son, my Yukon experienced catastrophic engine failure and I lost all propulsion control. The car went into neutral and I pulled along the side of the road safely to avoid an accident. As I put my car into park, the engine shut off completely and would not turn on again. There was no clicking sound and no attempting to turn over. I contacted roadside assistance and they sent a towing company to bring my Yukon to Century Buick GMC in Tampa Florida. The symptoms of what happened are similar to those of the recall. The dealership is replacing the engine however this is a critical safety issue as my son and I could have been severely hurt and or killed. Please investigate.

The engine failed and had to be replaced with less than 70,000 miles on it. There has already been a recall associated with these vehicles where a part is either replaced or special oil has to be used. It does not seem that the fix prevents the engine from failing.

NHTSA #11720131

My 2023 Yukon Denali is part of the L87 engine loss of propulsion recall. On August 28, 2025 my Yukon was inspected by Sterling McCall Buick GMC (where I purchased it) and it was deemed to have passed inspection. They changed the oil and installed a new oil fill cap and filter. On February 13, 2026 I took my Yukon to my mechanic for an oil change. Upon initiation, he advised me that he found the oil stick to be dry, no oil on the stick. There was no leak.

NHTSA #11718012

While driving down the road, my 2023 Yukon 6.2L engine shut down, shifted to neutral, and a message on the screen said “press start again” leaving my family in a powerless vehicle in the middle of the road in moving traffic. There were no warning signs nor is my vehicle included in a current recall. The vehicle will be taken to the dealership tomorrow morning.

NHTSA #11716367

Post initial remedy, which included oil sand cap replacement to 0-40, as directed by the manufacturer's recall documents, and passing the PicoScope test on August 26, 2025, the vehicle lost propulsion while traveling 58 mph, in the center lane of a busy, notoriously dangerous Saeford-Oyster Bay highway. At the time, the vehicle was occupied by a 2-week-old infant, the child's mother, and a dog. Prior to the failure, there were no indications of a pending or present issue. The vehicle's engine shut off, it shifted into neutral, and upon stopping, it shifted into a parked position, where it remains to date. Subsequent to pulling the vehicle onto the shoulder, the engine failed to restart. Approximately 6 hours later, the vehicle was towed to a GMC dealer, which subsequently confirmed that the engine is seized. The dealer submitted a report to GM to remedy the condition, pursuant to the manufacturer's recall instructions, but the manufacturer is yet to approve the remedy.

NHTSA #11717529

We received a notification that our 2023 GMG Yukon Denali Ultimate engine needed to be tested as a part of a recall. We took the vehicle to our local GMC dealership. The engine was tested and determined to "pass". The "pass", we were told, meant that we did not need a new engine, just thicker oil, and that the engine was safe. Mind you, our car was a custom order, took 8 months to receive, and is not even 3 years old. The vehicle is my everyday driver. I have two kids and live in a large city with a lot of traffic. A few months after it was determined to "pass", I was driving with my kids and dog in the car. The abruptly stopped, putting itself in neutral. Luckily, I had just turned off of a major interstate and onto a side road. The car would not start or move out of neutral leaving me and my kids in the middle of the road. It now needs a new engine. Prior to this issue, the battery died a few weeks after we took delivery of the vehicle. SAFETY!!!! If this happened just a few minutes prior, I would have been on a major interstate in one of the nation's worst traffic cities. My car would have abruptly shut down absolutely risking other cars hitting my car. All of this could have been avoided if GMC recalled AND REPLACED all impacted engines. The GMC service tech admitted that they (GMC) knew it was a "band-aid" that wouldn't work. GMC is putting lives at risk. In addition, we now have a vehicle we paid more than $150k for that is virtually worthless.

NHTSA #11712387

Vehicle had already "passed" the GM testing and received 0W-40 synthetic engine oil. Engine failure. Vehicle is currently at the dealership. This event put my family at risk of serious injury and possible death as the vehicle suddenly stopped working while drive on a bust street. Engine failure has been confirmed by the dealership, who have recommended installation of a new engine. There were no warning lamps on the dash at the time of the event. However, there was a loud noise immediately followed by lose of engine power.

NHTSA #11712393

Engine had a burning smell and cranking sound. It lost propulsion, no indicator lights were illuminated and the car shutdown while driving. This is a recall item. It passed the recall inspection. I also had it inspected prior to leaving for my trip 2000 miles from home. Im currently stranded and awaiting my options. This is very unsafe, the engine failed while I had no service within 50 miles. Freezing temperatures at sunset. Im being told that my towing and rental car may not be covered. GM told the dealership to do the oil repair first. They covered up the failure. I also had an issue with electrical items after the purchase and that issue is why my alert lights never came on even when the vehicle was Inoperable.

NHTSA #11711742

Car driving down highway at ~70 MPH with wife and our three young kids. Engine spontaneously shut off while driving. Electronic and other systems continued to function (power steering, brakes, lights, screens etc). Dangerous situation but was able to stop car in shoulder. Tried turning car on and off but car would not restart. Police were notified but did not come. Tow truck came and tuck car to a GMC dealer (GMC Danvers). Next day when techs arrived at dealer, they were able to start and drive car without issue. There were no present or stored fault codes other than a warning pertaining to the battery. Battery has been replaced and GMC is stating car is now safe to drive. Because issue could not be replicated by dealer and car did not store any fault codes despite the engine shut off, we question whether the issue has been correctly identified and repaired. We noted to GMC that the issue experienced was the same issue associated with the recent recall (for which the car was previously serviced). At this time we do not believe the work GMC performed under recall properly addressed the known engine shut off issue. We requested GMC and dealer perform another picoscope test to conform no issues with crank shaft. GMC refused to perform the service, despite us offering to pay for the test out of pocket. GMC is not offering any additional solutions to identify the cause of the engine shut off issue.

NHTSA #11707693

My vehicle was apart of the GM L87 recall. I took it to the dealership and it passed the recall and received the remedy which was an oil change. Now about 3 months later, I was driving in the highway at approximately 70 mph when the vehicle lost power and shifted to neutral. I had to attempt to veer off the highway with no acceleration. Upon getting it to the side of the highway, it wouldn’t do anything at all and had to be towed. The dealership has deemed it needs a new engine due to the failure the L87s are facing. We had no warning at all prior to the engine failure, and assumed that after passing a recall it had some degree of safety.

NHTSA #11707538

Vehicle was brought in for Campaign #25V274000 (6.2liter engine failure) and passed the manufacturer's testing. The oil was changed to a heavier weight with a new filter installed. Appx 770 miles later, the engine suffered a total failure. The engine was replaced under manufacturers warranty.

NHTSA #11712214

I brought my 2023 Yukon in for the 6.2 GM inspection, and was told my engine was good, and the engine oil was changed. Approximately 3 weeks later the engine in the Yukon failed (seized) while I was towing my boat at 55mph, nearly causing an accident. I was able to pull the vehicle and boat to the side of the highway in a precarious location, which put me, my family and property in danger. There were no warning signs or messages on the dash, and no engine sounds. I believe GM's recall inspection and "preventative" oil change did nothing, and gave me a false sense that the truck was safe to tow with. I want to make sure the NHTSA is aware that the engine failed even after being screened with the recall. THIS FALSE REASURRANCE THAT THE TRUCK IS SAFE IS PUTTING THE PUBLIC AT RISK

NHTSA #11704091

I was driving down 85 South bound at mile marker 16 the engine started messing up causing me and my family to be pushed over to the median. Once I was able to fight it over to the median it started smoking and i was afraid it was going to catch fire, so me and my family had to get out on the side of the interstate until help showed up and said it was safe to get back into the car. I had to use OnStar to get a tow truck, after the tow truck got there and i made it to the closest dealership to find out that the so called recall that the GM dealership fixed did not help the fact that the engine was messed up. So i tried to get a loaner or rental car for my family of 6 and they rented me a small SUV that I can not get all my kids into, I was told they did not have anything that bigger so now I am having to make multiple trips getting my kids to school. Plus they are saying it is going to be months before I can get my car back because the engine is on back order.

NHTSA #11698529

The vehicle engine experienced a failure on the highway at very high speeds with no warnings leading up to this occurrence, same as many of the experiences of the customers with the 6.2L engines, which have been recalled for these defects. This GMC Yukon has the 5.3L engine, however, has the same defects as the 6.2L engine, excessive oil consumption and eventually engine failure. I am without a vehicle, with an extremely high car loan, and have to replace an engine in a two year old $75,000 vehicle. This should be covered by GM as it was a known issue and continues to be sold to unknowing customers. Furthermore, I am paying even more money to put another engine in this vehicle with the potential of having the same issues as the problem has not been corrected. This is deceptive and theft by GM in my opinion, and not safe to have engines failing in the highway with no warnings at all.

NHTSA #11698845

At right under 40,000 miles the engine blew. The GM dealership that repaired my car would never tell me exactly what happened, and they were very sketchy about the whole experience, but it required a complete engine replacement from GMC when the engine quit working.

NHTSA #11714902

In April 2022, I purchased a brand-new 2022 Yukon Denali from Roberts-Robinson Chevrolet GMC in Excelsior Springs, MO. Shortly thereafter, the first engine failure occurred in October 2022. The vehicle was towed to GMC AutoNation in Golden, CO, where it remained until repairs were completed in January 2023. Soon after the vehicle was returned, the second engine failure occurred in February 2023. The vehicle was again towed to GMC AutoNation, and repairs were not completed until April 2023. At that time, given the repeated failures, I worked with GMC and Roberts-Robinson Chevrolet GMC to replace the vehicle entirely. I took delivery of a new 2023 GMC Yukon Denali as a resolution. On October 8, 2025, the engine on the 2023 Yukon Denali also failed, marking the third major engine failure I have experienced across these vehicles. The vehicle was towed again to GMC AutoNation in Golden, CO, where it remained for two months. I picked up the "repaired" vehicle on Tuesday, December 9, 2025. This pattern of failures has caused significant disruption and distress. I have spent countless hours coordinating tows, securing rental vehicles, and seeking reimbursement for out-of-pocket expenses. More importantly, these repeated engine failures, all of which occurred while I was driving 65 MPH on I-70 through the Colorado mountains, have created extremely dangerous situations for me and my loved ones. Navigating heavy traffic during sudden engine failure and waiting on the roadside for assistance has been frightening and unacceptable for a vehicle of this caliber. Overall, this experience has been incredibly stressful and disappointing.

NHTSA #11705913

Recall issued in April states that the Engine could experience a catastrophic failure and needs to be inspected for possible replacement. At this time (8-30-25) they are not allowing the dealers to perform these inspections. Why can't they at least perform the inspection to see if in fact the Engine will not need to be replaced? They are being irresponsible with their approach to this issue.

NHTSA #11683857

After stopping at a stop sign, I accelerated for a few seconds, but then it shifted to Neutral and the screen said "Press Start Again". I pressed Start, accelerated for a few seconds, and again it shifted to Neutral and the screen said "Press Start Again." I repeated this process a few times and luckily made it to the end of our driveway. I could no longer move the car nor could I shift gears. When trying to shift gears, the screen said "Conditions Not Correct for Shift." I requested Roadside Assistance. There is no way to get this car into neutral so he had to manually pull it onto the tow truck bed. The nearest dealership diagnosed it as engine failure and replaced the engine. There were no warning signs prior to this incident.

NHTSA #11684451

There's a recall on my SUV ... recall ID 25V274. The dealer told me that there is no part available currently so they refuse to inspect my SUV. I believe if the inspection revealed that there is no defect relating to the recall, the dealer is required to use higher viscosity oil. I've asked them to perform this inspection while they wait for the parts, but they refuse to do so. As summer vacation is here, what if the defect in fact does exist in my SUV that will cause a dead engine while driving on the highway, and we get hit by a semitruck killing me and my family. That would be too late isn't it!? How long must I wait for the parts and continue to put my me and my family's safety at risk?

I am filing a complaint regarding my 2023 GMC Yukon Denali Ultimate, equipped with the 6.2L L87 V8 engine, which is currently under NHTSA Recall 24V-266 for a potential engine failure due to defective bottom-end components. I received the official recall notice indicating that the issue poses a serious safety risk, including possible loss of propulsion and engine failure without warning. However, despite this being a mandatory safety recall, I’ve been informed by my dealership that no remedy is currently available, and I have been provided no timeline for repair or inspection. This effectively renders my $115,000 vehicle unsafe for normal use, yet I am left with no clear recourse, no loaner vehicle, and no repair timeline. I am now forced to restrict my driving to short errands only to reduce risk—completely unacceptable for a vehicle of this cost, class, and usage expectation. I am requesting that NHTSA formally investigate the timeliness and adequacy of GM's response to this recall and consider enforcing provisions of the Motor Vehicle Safety Act that require manufacturers to remedy defects within a reasonable timeframe. Thousands of affected owners are currently left without a fix for a potentially dangerous engine flaw.

[XXX] [XXX] [XXX] April 17th, 2025 Spearfish Cadillac Attn: [Service Manager or General Manager] North Main Spearfish, SD 57783 Subject: Engine Failure and Safety Concerns – 2023 GMC Denali Ultimate (6.2L V8) Before ordering my 2023 GMC Denali Ultimate (MSRP $96,000), I raised concerns about online reports of engine problems with the 6.2L V8. I was assured by your staff that there were no known issues with this engine and that I had nothing to worry about. However, within the first year of ownership, I began reading verified reports about widespread engine failures involving this same 6.2L engine across various GM models. I contacted your dealership again and was told that my vehicle’s VIN did not indicate any problem or need for replacement. Since that time, I have experienced two severe engine failures, both at highway speeds of approximately 80 mph. Each failure caused my vehicle to abruptly shut down and lurch into a different lane of traffic—creating traumatic and extremely dangerous situations for both myself and surrounding drivers. In addition, I encountered another instance in which the engine would not start. A stranger helped me jump-start the vehicle on two separate occasions. Believing the issue could be battery-related, I replaced the battery (which was less than three years old), only to suspect later that the engine may have partially locked up. I am formally requesting the following: A written response confirming whether a replacement engine has been or will be installed in my vehicle, and if so, whether it is a new build, remanufactured, or an identical L87 engine model. Confirmation of whether any updated parts or engineering revisions were made to resolve known lifter or bearing issues.

The evening of Tuesday [XXX] driving from College Station, TX to Pasadena TX my GMC 2023 GMC Yukon starting making a clicking noise but no warning lights. For about an hour the noise persisted louder and softer and the check engine light would flash 3 times then stop, for a while then flash again. I did notice that when applying gas I didn't get the normal increase in acceleration but I couldn't tell if it was a power issue or a transmission issue. I was traveling about 60mph on a freeway thankfully in the right lane the vehicle suddenly shut off with no warning. I had no power, brakes did work and I could steer and I was able to make it to the area between the main lanes of the freeway and the lane of an onramp. Once stopped I attempted to restart the vehicle and nothing happened. We were stuck. Onstar was contacted and a tow to a dealership was arranged. A sheriff deputy stationed his vehicle behind us to provide protection until the tow truck arrived. The vehicle is now at a GCM dealer and I have been told the engine has locked up and needs a complete replacement. I have no other information in those regards. There is a long back order for new engines and the estimate is at 4 weeks. I did see the check engine light flash 3 times and then go off for a while then start again, but we were no where close to home and it was somewhat late at night. I also had coworkers in the vehicle taking them back to our office. At this point this is as much as I know but thankfully i was already in the right lane or this might have been a much more difficult situation.

I was driving approximately 45 MPH and my 2023 Yukon STOPPED completely and it would not move at all, it stopped just into where the intersection starts. After 2 hours it was towed to the GMC dealership. I am now told that it needs a new engine at just 15,000 miles. Apparently this is a “thing” I had no warning whatsoever. The dealership has it now and it is waiting on a new engine. Extremes scary and now they said they will put a new one in and it “shouldn’t happen again”. Ridiculous Engines are on back order for at least 60 days because of this problem I’m told.

Driving 75 mph on [XXX]. No power under gas pedal. Transmission shifted on its own to neutral and there were no lights warning on the dash. Yes my safety and that of 3 children ([XXX, XXX, and [XXX] ) as well as my mother [XXX] ) and my wife [XXX] ) were all put at risk. I had no way to accelerate or warning from the vehicle that the engine had failed. It just so happened my wife noticed it was in neutral and luckily I had room to get from the left lane to the shoulder where the speed limit is 75 mph. Dash information center said "Press start to restart vehicle". I pulled off safely to the shoulder with 7 passengers (including myself). Tried to restart the car but it was no working. The vehicle wouldn't shut off the electrical accessories either and kept repeating the same warning. The vehicle was inspected at the dealer after it was towed. There were no warning lights or signs of any issues prior to this incident. Had the vehicle for less than 2 years and under 19k miles. GM towed the vehicle to the dealership who held it for the weekend and then Monday afternoon told me the engine was blown. I was not offered a comparable vehicle under their warranty to replace it and was told I need to wait an unknown amount of time to get the vehicle back on the road as all engines are on back order.

We were driving our 2023 GMC Yukon AT4 from Phoenix, Arizona to Flagstaff, Arizona, which is about 2.5 hours north. A few hours into our drive, about 40 miles away from Flagstaff, as we were driving ~75mph on the [XXX] highway (in the middle of nowhere), all of the sudden our GMC just stopped working - it started slowing down on its own, put itself into Neutral, and nothing was working. We were able to pull over to the side of the road where we used OnStar to reach GMC Service, who called us a tow truck. As we were on with OnStar we tried restarting the vehicle and nothing was responsive. For hours our family, two adults and one child, were stuck on the side of the [XXX] highway with semi-trucks flying by us waiting for the tow truck. We were then told the two truck could only fit two persons, so I had to order my own Uber to pickup myself and my son in the middle of nowhere, leaving my husband to wait alone, dangerously, for the tow truck. Important to note a major winter storm was coming in this afternoon, so with no power it was also freezing cold in the broken down vehicle. The GMC was towed to the Chevy dealer/service center in Flagstaff, who was able to have a mechanic look at the vehicle that day. After a few hours they contacted us and let us know the entire engine blew and would need to be replaced. They let us know this is a "known issue" with certain Chevy/GMC/Cadillac SUV's that have the 6.2 engine. We purchased this vehicle brand new in late 2023 - at the time of this "catastrophic engine failure" issue, it had only ~12,000 miles on it. We were forced to leave our GMC in Flagstaff for repair, and told it would likely be 4 weeks or more to get the new engine. We were also left without a 4x4 vehicle for the entirety of our "vacation" in a major winter storm. There were no warning lamps, messages, or other symptoms of the problem prior to failure.

I was traveling on the highway when my 2023 Yukon Denali engine shut off and switched to the neutral gear with any warnings. The dashboard display read "press start again" as I coasted to the shoulder of the highway. I was able to put the vehicle in "park" and re-start the engine after a couple of tries. I got a couple miles down the road, got off on an exit ramp then it shut off again and I again coasted to the shoulder of the highway. Again the display read "press start again", but this time the vehicle would NOT restart at all. I had full electrical power in the vehicle during both engine failures. I had the vehicle towed to my local GMC dealership. The dealership told me that I needed a new engine after assessing the vehicle.

This vehicle had a complete engine failure. We lost power and could not start it. We were stranded on a busy highway. This all happened going 65 mph. The dealer told us that we would need a complete engine replacement. We had about 16,500 miles on it. I personally know two other people that this has happened too.

We own a 2023 GMC Yukon Denali with the 6.2L engine. On [XXX], I was driving to work and merging into traffic on [XXX] just south of Nashville. When getting up to speed, the engine shut off and the truck started to decelerate. Only warning light was notification to "Hit Start Button" - which off course I was feverously doing as I was in rush-hour traffic. Luckily, I was able to move across two lanes and came to a stop on the freeway shoulder. Called OnStar services where they sent a tow truck, but the driver didn't know how to tow the truck since he was unable to shift into 'neutral' as the electronic system didn't allow that without the motor on. A second tow truck was sent by my local dealer and then they had to 'drag' the Yukon onto the tow truck bed so they could haul it. After the dealer reviewed the issue, determined we needed an entire motor as the engine oil had metal shavings in it and had frozen the motor. We are one of seven vehicles at our dealership waiting on a new 6.2L motor. GM has provided a large SUV rental during the time we have been waiting.

WHILE DRIVING ON HIGHWAY ON 2/21/25. MY 2023 YUKON (WITH GM ENGINE L87 IN IT) WARNING LIGHT CAME ON CALLING THAT THE TRUCK SHIFTED INTO NEUTRAL, PRESS START. PULLED OVER TO BREAK DOWN LANE, RESTARTED AND WENT ON OUR WAY. CALLED DEALERSHIP AND THEY HAVE NOT HEARD OF ANY TYPE OF ISSUE AND STATED TO BRING BY IF IT HAPPENS AGAIN. 8 DAYS LATER THE 2023 YUKON WITH GM ENGINE L87 SIEZED ON 3/1/25 WITH ~23,000 ON IT WHILE DRIVING ON THE HIGHWAY. VECHIE WAS TOWED TO GMC DEALERSHIP WHERE THE SUV WAS PURCHASED AND HAS BEEN SITTING EVER SINCE WHILE WE WAIT FOR A NEW ENGINE COME IN. DEALER HAS BEEN HELPFUL, BUT I HAVE READ THAT THERE IS A BIGGER ISSUE WTH THE L87 ENGINE.

On Friday 2/21/25, while driving on the Interstate at Highway speeds, the dashboard said to idle the engine. The engine then stalled and thankfully I had enough speed and there was a shoulder available to pull off on. The dashboard then gave many messages including voltage, overheating, high oil temperature, idle engine, etc... I was unable to restart the vehicle on the side of the interstate. I was towed to the dealer who advised the engine would have to be replaced. This vehicle has a 6.2L gas engine with 39,223 (approx) miles.

catastrophic engine failure

NHTSA #11643147

Traveling at 65 MPH on highway when electronic dash went completely blank, audio on car stopped as did the engine! Steering of vehicle remained in tact so I was fortunate to be able to "coast" to the side of the highway. GMC Dealer has confirmed a total engine failure and stated they will need to replace the entire engine. There were no prior warnings, symptoms or problems with my vehicle prior to this incident.

NHTSA #11643491

I was driving home from work at around 60 mph. Very sunddly their was a rattling metal sounds and then vehicle struggled to maintain speed. Before pulling off the highway at the next exit. On the exit ramp the engine turned off and would not turn back on. The vehicle was also stuck in neutral and not able to shift out of neutral for towing. There was no worning lamps or messages even after the noise and reduced power. Vehicle was towed to local dealership on Tuesday evening, as this was not scheduled it took them to diagnosis the issue as engine failure and recommending to replace the engine. The vehicle is a 6.2L GMC Yukon Denali with 23k miles. All service has been done at the dealer with no outstanding work prior to the engine failure. Where it gets more disappointing is the lack of information for time to fix. The replacement engine was ordered by the dealer on February 14th. As of February 28th they did not have any information....So i called GMC on that 1800 number listed on GM Document DCS6866 referencing customer satisfaction program N232413430. The first agent disconnected without filing a case. The second agent had to restart the process and was told that there was nothing they would do for 14 days after the case was opened before it would be elevated. When talking to the agent they denied any information related to the GM Customer Satisfaction Program or any knowledge of what seems to be a wide spread defect on 6.2L engines. The service and support for a $90k vehicle from, in fairness they have provided access to rental vehicle from a local auto shop. The vehicle is far smaller and different from our vehicle we purchased. The vehicle is still sitting at the dealership service center and is not functional until the engine is repalced.

While driving my 2023 Yukon Denali on [XXX] towards [XXX] , the check engine light came on and my truck stopped hard as if I jammed the brea but my foot was still on the gas and the RPM’s was moving. I was lucky that I was in the far right lane and there was no car behind me at the time or I would have caused an accident. I after 30 minutes waiting on the side of the road, I started up my 2023 Denali after letting it sit and put it in drive and drove 30 mph because I did not want to take the chance of my suv stopping abruptly again. I contacted a GMC Dealership and explained the situation and I told I am on my own and I would have to pay up to $10,000 for a engine and it would be no guarantee of being reimbursed by GM should I need a engine.

i was with my entire family 3 hours from home on a ski trip loaded with gear and the motor decided to go. i had to pull into an abandoned lot, leave my family in a car with no heat, walk 6 miles up a mountain to get another vehicle and pick up the family. Then i had to call a local tow company to drive out pick up the vehicle and myself and drive 3 hours home drop the vehicle at the dealer and then myself at home. The vehicle was not even pulled in for 2 weeks to be looked at (no other vehicle was available) and then they told us the motor was shot - lifters cam and other things and that the head gasket was on back order indefinitly. This happened the beginning of February its now March 6, the vehicle is in pieces at the dealer with no time frame of when we can get it back. Meanwhile its costing me 1670$/ mo plus insurance. For a 100k$ vehicle to go with 30k miles is wildly unacceptable. I have had no luck getting a return call from a representative with GM which is why i am filing this complaint now.

Our Yukon Denali at around 34k miles lost power while in motion, it automatically put it in neutral and said try to restart. Rolled to a stop in a turn lane and when we tried to start ignition…nothing happened. On star was called and ran diagnostic, showing no issue. Towed vehicle to dealership and the engine seized up. 4 piston rods had broke and the engine needed to be rebuilt.

While we were driving at a high speed all control of the vehicle shut down. There was absolutely no warning that this was going to happen to that anything in the vehicle was breaking down. We were able to get to the side of the road and the vehicle locked into N. From that point on the car did not work. After being looked at my GMC, they decided that it needs a new engine. It only has under 15K miles. We were told that some somehow pieces of metal were in the engine. Engines are currently on a national backorder and we have been without our vehicle for over 4 weeks. They have no expected date that this will be fixed.

On Jan. 19, 2025, while driving home, I started hearing a loud knocking noise from my engine. Lucky I was still on residential streets so I was able to safely pull over to a parking lot. I was planning to drive the 40 miles home on the freeway when my wife said it might not be safe. That was when I decided to drive to my sister's house. Only when I pulled into the drive way the check engine light finally came on. The next day, I had the vehicle towed to the dealership and they diagnosed that I needed a new engine. They did not go into specifics as to why I will need a whole new engine but they did tell me that this was common and that they had other vehicles waiting for an engine also. My vehicle has been sitting there since.

January 16, 2025: Driving down the interstate near Atlanta Ga going 75 MPH, our 2023 Yukon Denali with 28,585 miles on it, abruptly started gearing down. The vehicle would not accelerate, it was coming to a stop on its on. Traffic was very heavy and it was a very scary situation. After managing to get the vehicle barely off the interstate it totally lost power and would not start.

We had to get a rental car to continue our trip and haven’t had much luck, so far, getting reimbursed. As of today February 6th, GMC cannot give us an estimated repair date as our engine is on back order!

The engine turned off while driving TWICE with NO WARNING. The first time the engine turned off without warning doing around 60MPH but was able to be restarted and ran normally for about a week or so. The second and final time that the engine turned off without warning was about a week after the first incident. The engine would not restart, in fact, it would not even crank. The vehicle was towed to the dealership where it was determined to be a crankshaft bearing failure causing a bottom end engine failure. Metal shavings were found in the oil pan. Vehicle is only 14 months old and has 22,754 miles. All service was done by dealer at manufacturers suggested intervals.

Owner was driving at highway speeds and the vehicle experienced multiple sudden stops. After consulting with the GMC certified repair facility, the control valve body of the transmission was determined to be faulty and replaced.

My name is [XXX] , and I am writing to formally lodge a complaint regarding a serious safety defect in my 2023 GMC Yukon with a 3.0 Duramax diesel engine. The issue involves the transmission valve body, which has caused rear wheel lockup at highway speeds. I experienced this issue at 34,000 miles on my vehicle, and it has been in the shop for over 5 weeks with no estimated time on parts availability. Despite opening a case with GM support, as detailed in the attached email transcript, I have not received a resolution. GM has refused to replace the complete transmission on the vehicle and only offered to replace the valve body. This is unacceptable as the defective valve body has already caused damage to the transmission. I also opened a BBB Auto Line case, which was closed immediately after I denied the offer from the GM support representative. This raises concerns about a potential conflict of interest, as the BBB Auto Line seemed aware of my interactions with GM support. I am seeking a complete transmission replacement with a valve body upgrade kit from NextGen transmission, which I believe would resolve the issue. However, GM has not accepted this offer. I request that the NHTSA investigate this matter promptly to ensure the safety of my vehicle and others that may be affected by this defect. If this issue is not resolved, I will have no choice but to pursue legal action. Thank you for your prompt attention to this matter.

On April 30, 2025, my 2023 GMC Yukon with 68,000 miles on it (8,000 miles outside of the warranty and that I had purchased on 4/27/2024) randomly downshifted as I was turning into a parking lot and gave me a computer notification stating "Service transmission now, unable to shift soon." I immediately put my car in park and called OnStar for her to read me the computer code. She said it came up with two codes so we brought it to Wyatt Johnson GMC in Clarksville Tennessee. They plugged in their computer reader and that's when the service provider informed me that my car was un-drivable because it was unsafe. We left it there for them to do a diagnostic test on it to see exactly what is wrong with it. A few days later they contacted us and informed us that it was a malfunction in the transmission valve body. The dealership informed us that it would cost $2754.25 to fix but the issue is the part is on back order and they don't know when it will be available. We have been in contact with the dealership and with General Motors customer service almost weekly trying to find out, when the part will be available and where I am on "the list" and no one has an answer. With the personal research that I have done, I have seen that people have been waiting for over a year. I also know that there are current class-action lawsuits for GM's Yukons for years a little older than mine and currently multiple complaints for the newer Yukons for the same transmission valve body issues. The dealership does not give out loaners anymore after Covid. I have asked, general motors. Customer service has informed me that it's up to the dealership if they will give me one General Motors said they would look into a possible reimbursement program if I have to purchase a rental, but they will only cover a car that cost $44 a day and that is not including taxes and extra fees, but I can't afford to rent anything and I'm missing work.

The vehicle drove fine had no warning/ check engine lights. My girlfriend came up to a busy intersection and when she proceeded to cross the intersection the vehicles motor locked up stopping the vehicle in the middle of the intersection with traffic coming from both north and south direction. We had poor visibility due to blowing snow so she had to bail from the vehicle and stand on the side of the road so she would not be harmed if the vehicle was t boned. Vehicle stopped so hard and fast it threw her into the steering wheel. Was unable to get the vehicle restarted and could not get it to shift into neutral so vehicle blocked 1 lane of traffic completely and half of another lane until tow truck arrived to remove from road.

While driving on the mass pike with my fiancé and 4 kids our motor suddenly died. We were using cruise control going 75mph and the vehicle shifted into neutral itself and the car died. I managed to make it to a break down lane and we had to sit there for 2.5 hours before a tow showed up to help. The dealership said the motor seized and we were under the 60K for warranty and it was covered. They got us a rental the next day and then on the 3rd day they called and said it was lack of oil changes that caused it and they asked if i had records of service history. We bought the vehicle used and only had the vehicle long enough to perform 1 oil change. We did our oil change on time and I'm trying to locate service records from the dealership we bought it from. However there were no signs of dark and contaminated oil when i did the oil change at my shop and also no sounds or warnings coming from the vehicle prior to the motor seizing up. I think they are trying to get out of paying for the motor when its clearly a known problem with these 6.2l engines.

My vehicle experienced a sudden and complete loss of OnStar and telematics functionality during or immediately following a routing/software update. I had taken my vehicle in for my engine recall and noted another software update was required and specifically was told by multiple service members over the phone that the onstar services/telematics module was impacted and this update should resolve it. After some initial research it appears this is related to N212331730, which impacts OnStar and telematics services. I brought the vehicle to an authorized GMC dealer for the recall. After inspection, the dealer informed me that the telematics control module has failed and must be replaced. This failure resulted in the loss of all OnStar safety-related services, including emergency response and vehicle communication features. The failure appears directly related to the recall condition or software update process, yet I am being told the module replacement is not covered. This creates a safety concern because emergency communication systems required for crash response and roadside assistance are nonfunctional. I am concerned that the recall remedy may be causing or accelerating telematics module failures and that affected vehicles may be left without critical safety systems unless owners pay out of pocket.

we brought my 2023 gmc yukon into Parks GMC in greenville sc on july 26, 2025 for the engine recall that we received a letter from. We left it as we were going on vacation for the week and picked it up the following saturday august 2nd. the next week my engine light started lighting up and my husband contacted the dealership and we were asked to bring it back in. We did and were told that we now had a bad Telematics Communication Interface Control Module that was causing my engine light to come on and that we were going to have to pay $600.00 out of our pocket to have this repaired. After researching we found that this is a VERY common and widespread problem with a lot of owners right after they bring their vehicles in to be serviced. We declined the repair, one because they did not have the part in stock as that apparently is also a big problem of not being able to get the part in stock and two because we feel like we should not have to pay to have this part replaced as it appears to be a widespread issue that is happening. The dealership also charged me $182 for diagnostic charges that I once again feel like we should not have had ton pay.
