general problems of the 2023 GMC Yukon - part 2

The contact owns a 2023 GMC Yukon xl. The contact stated that while driving 70 mph, the vehicle stalled, and the engine seized. There was no warning light illuminated. The vehicle was coasted to the side of the road. The vehicle failed to restart and was towed to the dealer, where it was diagnosed with engine failure. The contact was informed that the engine needed to be replaced. The vehicle was repaired. The contact stated that the vehicle had previously been repaired under an oil consumption-related recall. The manufacturer was made aware of the failure by telephone, and a case was opened. The failure mileage was approximately 34,000.

My car started making a knocking noise under the hood 2 days prior to it breaking down (6/19 & 6/20). On 6/21/26, I was driving down the interstate with my kids in the car and it shut down on its own. Lights came on my dash and the vehicle quickly slowed itself down and when I pulled over to a complete stop, the vehicle shifted into neutral and shut off. I was not able to crank it back up and had to pay a tow company $243 out of pocket to tow it to our local dealership in town. My insurance only covers $200 for towing. I am a week without a vehicle and just found out Friday (6/26) that a new motor will have to be ordered but it is on back order with no idea on when it may arrive. I cannot get an answer from gm or my local dealership on if a rental will be provided. I cannot make 2 car payments but I also have a job and cannot proceed without having a vehicle to drive. This has put me in a bind for a week already with no solution in sight. I expect gm to fix my problem ASAP since it is theirs to fix!!.

Vehicle had previously undergone the gm 6. 2l engine recall inspection on October 17, 2025, and was determined to have passed. On June 13, 2026, at approximately 80,390 miles, the vehicle suddenly lost propulsion while being driven with five children in the vehicle. The vehicle became inoperable and required towing. Dealer subsequently diagnosed engine failure and has ordered a replacement engine. This failure happened with out warning.

2023 Yukon with 6. 2; was "tested" at a local dealership in November 2025. Engine passed. Was given oil change with new oil/oil cap. In June of 2026, engine seized despite passing test in November & running the new oil since then.

Engine knocking vechile had loss of power. Had towed to dealer. Throwing all kinds of codes 6. 2 l v8. Truck passed gm crap test in September and here we are at 59,000 with a blown motor. Lucky it did not go out under power and kill me or my small kids and family that was going to vacation with this truck the next day.

My 2023 GMC Yukon denali xl, used as a commercial vehicle for my business, experienced sudden and complete engine failure at approximately 70,000 miles with no prior warning. No check engine light, no unusual noise, and no other symptoms. The vehicle had previously been inspected/serviced under gm safety recall 25v-274 (l87 engine loss of propulsion) and had been deemed safe prior to this failure. The failure occurred while driving on a two-lane road in durango, CO. The vehicle lost all propulsion and came to a stop in the roadway, blocking the lane of travel and forcing other vehicles to cross into the oncoming traffic lane to go around the disabled vehicle. This created a serious and immediate hazard to myself and to oncoming traffic. The vehicle was not driveable and had to be towed. The dealer confirmed catastrophic engine failure requiring a complete engine replacement. After the engine replacement, the morehart murphy GMC dealership in durango also failed to properly recalibrate vehicle sensors. They did not reinstall certain suspension components that had been removed for the engine replacement, requiring multiple additional dealership visits to resolve along with recalibration of the air ride suspension. After the replacement I was getting messages that the vehicle was "too low to drive with caution" and "reduced acceleration drive with care. " this vehicle failure occurred during our peak season (June 10-July 2). The vehicle being out of service, I was required to rent a replacement vehicle at my own expense because gm did not provide a loaner vehicle. I estimate loss revenue at $1k/day. When I attempted to raise this issue with gm directly, their response was to submit letter to a p. O. Box, with no other means of resolution or contact offered. Given that this vehicle had already undergone the recall remedy and was represented as safe, this incident is relevant to NHTSA's ongoing investigation into post-recall l87 engine failures (recall query rq26001).

Lost power going down highway and coasted to a stop on the side of the road. Car was towed to a nearby GMC dealership and after inspection a new 6. 2 motor is needed. I did not notice any warning signals when I lost power.

Completed the oil change requirement in the recall for the 6. 2l but engine blew while driving on I-10 while doing 75mph. 50k miles. Completely left stranded on major highway with family in car and vehicle flying by. Gm needs to be held accountable. Their fix is not a fix.

I had the recall remedy of the v8 completed. They said it only required thicker oil which now lowers fuel economy and costs more for oil changes. After the recall, the engine still makes a knocking sound.

The contact owns a 2023 GMC Yukon. The contact stated that while driving at an undisclosed speed, the engine became inoperable, causing the battery to discharge. The contact further stated that no warning lights illuminated prior to the failure. The vehicle was taken to the dealer, where it was diagnosed with a seized engine; however, the vehicle was not repaired. The manufacturer was not notified of the failure. The approximate failure mileage was 31,000.

Recall notice received, went to dealer to have inspected and was told it passed the recall inspection. Oil changed from 0w20 to 0w40. Motor locked up less than 3000 miles later. My wife was 2 hours from home on the interstate on a Saturday night. Was forced to the left shoulder of the road pinned between concrete dividers and the fast lane. Had to wait 2 hours for a tow truck, $500 later the Yukon was delivered back to our driveway. Mind you, the electronic transmission can’t be shifted so it was dragged on and off a rollback in park 4 times. Dealer had it towed to their shop where they discovered the blown motor. 2 months later the replacement motor was installed.

On may 8th of 2026 my 2023 GMC Yukon with approximately 42,900 miles experienced an complete failure of the 6. 2l engine requiring replacement. The engine failure occurred despite the engine having recently undergone inspection and special oil being used related to NHTSA 25v274 / gm n252494000 recall. When the engine failed, the vehicle could not be towed or pushed out of the flow of traffic because the computer will not allow the vehicle to be shifted into neutral, only showing "conditions not correct for shift" in the instrument cluster. This sudden and unexpected loss of engine power combined with the inability to remove the vehicle from the lane of traffic creates a dangerous situation.

I was traveling with my family on the ohio turnpike. We were traveling west in our 2023 GMC Yukon denali when we lost all propulsion and the engine seized. There was no warning lights or other symptoms prior to this incident on may 3, 2026. In fact, I had the vehicle in for the prescribed recall to test the engine for the known defect earlier in 2026. The vehicle passed that test and was given the upgraded oil change to presumably prevent the engine failure in the future. It did not work. Our safety and others on the turnpike were at risk while we were traveling at highway rates of speed with sudden loss of all propulsion. The vehicle was towed that evening to local gm dealer - yark chevy in [xxx] . Upon inspection on may 5, 2026, the dealership informed me the engine had seized and would be replaced by gm. They were unable to provide a timeline for this repair. I have the tow expense of $260. 70 and now the uncertainty of when I might have a vehicle back. The safety of my family and all others traveling the ohio turnpike that date were at significant risk. The vehicle remains at yark chevy in perrysburg, ohio available for inspection upon request.

This vehicle was identified as recalled in 2025 for total engine replacement and the engine did fail in may 2025 it would stall while driving. GMC performed the engine replacement in June of 2025. The car stalled again on Friday may 1. It was taken to the dealer on may 7 and was diagnosed as needing another complete engine replacement. I was told that GMC identified a need to replace more parts after my engine was replaced but I was never informed of this. I was told my this dealership that I am the first vehicle they’ve seen that will require a second full engine replacement it is a 6. 3l v8. This car stalled while I was driving with a 3yo in the vehicle.

My 2023 GMC Yukon denali is currently at the dealership due to a manufacturer recall involving the engine. The engine issue occurred while I was driving with my children in the vehicle, which required me to pull over and have the vehicle towed to the dealership after inspection, I was told the vehicle requires a full engine replacement. The dealership has stated there is no estimated time of arrival for the replacement engine due to backorder, and that other customers have been waiting for extended periods. I am currently without my vehicle and have been provided a temporary replacement that is not comparable. The extended delay and lack of timeline are causing significant loss of use.

I am filing this complaint regarding my GMC Yukon denali, currently at greg lair GMC in canyon, texas, for gm safety recall n252494000, NHTSA campaign number 25v274, l87 engine loss of propulsion. My vehicle has been at the dealership for over two weeks for this recall, which in my case requires a complete engine replacement. I have been advised the repair may take another 4 to 5 weeks. During this time, neither general motors nor greg lair GMC has provided a comparable loaner vehicle or adequate transportation. This is not routine maintenance, elective service, or damage caused by me. My vehicle is unavailable because of a gm safety recall involving potential engine damage, engine failure, and loss of propulsion. The burden of this manufacturer issue should not be placed on the customer. I was told gm only can reimburse $44 per day for a rental. That amount does not reasonably cover a comparable vehicle to a Yukon denali and may not even cover a basic rental in the current market. A compact sedan or small vehicle is not an acceptable substitute for a full size SUV. I pay for and rely on a Yukon denali because my family needs the seating capacity, space, size, safety, and functionality of a full size vehicle. My family has more people than seats available in many compact vehicles. Being forced into a smaller vehicle is not only inconvenient, it creates a safety and functionality concern. If this recall is widespread and repair times are expected to take several weeks, general motors should have ensured that dealerships had access to comparable loaner vehicles or adequate rental authorization. I should not have to compromise my family’s safety, transportation needs, work obligations, or daily responsibilities because of a manufacturer safety recall and complete engine replacement. I am requesting that this complaint be documented and reviewed. General motors and greg lair GMC should provide a comparable full size SUV loaner, arrange and pay for a full size SUV.

I am filing this formal complaint to report a series of catastrophic, life-threatening mechanical failures involving my 2023 GMC Yukon. This vehicle has become a weapon on the road, exhibiting erratic behaviors that nearly resulted in a multi-vehicle fatality on a high-speed highway. 1. High-speed power loss (highway failure while my wife was traveling at 60 mph in heavy highway traffic, the vehicle’s transmission spontaneously and without warning disengaged and shifted into neutral. This caused an immediate and total loss of motive power. In a split second, my wife was left piloting a 6,000-pound unpowered projectile in the middle of high-speed traffic. By the grace of god alone, she managed to navigate to the shoulder without being rear-ended. This is a clear "sudden loss of motive power" defect that poses an immediate threat to life. 2. Unintended directional movement (reverse shift) following a total engine replacement—a repair that took over 45 days—the vehicle has now developed a new, terrifying defect. While stopped at a traffic light, the vehicle spontaneously engaged in reverse. This unintended movement occurred without driver input, creating a high risk of pedestrian strikes and intersection collisions. 3. Systematic failure and dealer evasion the vehicle previously exhibited "ghost shifts" into park and neutral at low speeds. Despite my repeated warnings to the general motors service department, I was dismissed until the engine ultimately failed. Furthermore, the dealership has been inconsistent and evasive regarding the serial numbers of the replacement components, leading me to believe that unsafe or defective parts are being recycled into these vehicles. General motors is aware of these powertrain defects, yet they continue to allow these "death traps" to remain on the road. My family will not be the "crash test dummies" for gm’s manufacturing negligence.

I was on the highway heading home with my [xxx] son in the backseat and without warning the engine shut down and luckily we were on the exit ramp and away from heavy traffic. I pulled over to the side and tried to start it again but it won’t even crank. The cabin heater stopped working too, it was -9 degrees outside that day and we started to freeze, luckily my wife was able to get to us in 20minutes. The vehicle was towed to gm dealership and they confirmed the engine seized and will need a new engine under special coverage n252494003-03. This was after the recall was completed for this vehicle. It had only 61392kms on it. We live in [xxx] and it gets extreme winters with below -40degree temperatures. It’s a remote area and there is no service on the highway for 200kms when heading south to city, if this would have happened on the highway with no services and extreme weather we wouldn’t have made it out alive. We are a family of 5 with a [xxx] and a [xxx] and we bought this vehicle after knowing that the engine recall was completed and gm deemed it safe. Unfortunately that’s a lie and gm is putting peoples safety and life at risk. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

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.

Engine seized after the pico test. Been 3 months waiting on an engine.

On 2/28/26 I experienced complete engine failure on my 23 Yukon. I was going 70mph on the highway when the engine kicked and and kicked into neutral. The car spent 6 weeks in the dealer to have the engine replaced. I picked up the car on Wednesday, 4/15. On 4/16, I was once again driving, as normal when it suddenly turned off and kicked into neutral. 1 day after I picked up the vehicle it is once again being towed back to the dealer for the same symptoms it had when the entire engine had to be replaced. Both times, there is no warning. The car dings and a message comes up saying "restart vehicle". On 2/28, the car would not restart. On 4/16, the car did restart but only temporarily this is a major safety problem. The first occurrence I was going 70mph on the highway when I lost power. The second occurrence, I was driving 20mph on my neighborhood street and suddenly lost all power.

Ok so my first issues were with the vehicle stalling while driving in gear. Happened a few times intersections off-ramps etc…and the car would roll to a stop. Luckily no one killed. Again happened a few times. Went to dealer they “fixed”it. Then it happened a couple other times…scary shit…went to dealer then they“fixed” it again. Happened again I didnt bring it back. By this point I was carrying a 10 millimeter wrench in the glovebox to disconnect the battery so the body computer would reset. Car would start after cycling the power from the battery terminal. And those were my electrical problems …as far as mechanical problems I brought car in for the recall notice “ the pico test’ . Went for the recall oil change /test/per the recommendations. 300 miles later car engine failure at 70 miles an hour on route [xxx] south wife driving. She started crying doesn’t want anything to do with this car. Too many incidents… safety of my family at risk. Please help. Fyi I am a mechanic / car electrician [xxx] so could probably be much more descriptive if need be tow trucks ubers rental cars etc… shit show. Engine died April 16 so car has been at a dealer in [xxx] for 31days. I have dealer receipts and some play by play video of a few of the incidents information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

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.

This car was subject to the gm recall n2524940000 – this is related to engine failure in the vehicle. My Yukon denali received the recall service on xxx at liberty Buick GMC in xxx. It was determined that my engine would not fail and the car needed the heavier oil and a new oil filter. The car also received a 10 year warranty on the engine as part of the recall. Xxx we were traveling down xxx southbound on xxx headed to atlanta to see family for easter break. My wife, son cj (age -xxx), xxx (xxx), and our english cream golden retriever , goose. We were traveling at 75 mph on cruise control when a car came out in front of me. The car slowed down to adjust for the car moving out in front of us and then the engine completely shut-off and the car shifted into neutral. The car electronics turned off briefly, then came back on, with the dashboard saying “push start to turn on”. I hit the start button and nothing happens, I pushed the button several more times and still nothing happened. This occurred between 1:45 - 2:00 at this point, I begin to move into the right lane as we are approaching exit xxx in [xxx]. I pull off on the exit, go about half way down and pull to the side, stopping the car. I place the car into park and then push start on the car, nothing happens. I attempt to do this for about 5 minutes and the engine still will not start and the car will not shut off completely (all electronics are still working). There were no warning signs that the vehicle would fail. The vehicle was inspected by GMC who determined that the engine had failed and would require full replacement. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

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.

The contact owns a 2023 GMC Yukon. The contact stated that while driving at an undisclosed speed, the engine seized. No warning lights were illuminated. The vehicle was towed to the dealer and was diagnosed with engine failure. The contact was informed that the engine needed to be replaced. The vehicle was repaired. The contact was informed that the repair was covered under an unknown recall repair. The vehicle was released back to the owner; however, the failure reoccurred. The contact stated that the vehicle was idling roughly and jerking abnormally. In addition, the contact stated that the drive to the residence was not a smooth drive. The vehicle was taken back to the dealer, where a technician performed a ride-along. The contact stated that the engine seized three times during the ride along. The contact was informed that the engine needed to be replaced a second time. The contact stated that when the vehicle was released, the rear bumper was damaged. Additionally, while attempting to start the vehicle, the forward collision avoidance warning light was illuminated. The vehicle remained with the dealer. The manufacturer was made aware of the failure, and a case was filed. The failure mileage was approximately 44,000.

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.

The vehicle has the l87 gm engine. It lost complete power and the engine seized up and would not start again. Fortunately I was able to roll into a neighborhood and get off the main road with no issues. The dealer has confirmed the seized engine and a replacement engine has been ordered with no eta. There was no prior warning of the failure, besides a shuddering, like I was running out of gas, and then a lose of complete power.

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.

The 6. 2l motor in my GMC Yukon failed due to the camshaft and stalled me in an intersection on a highway. Had to shut the lanes down to get towed. Lost all power and couldn’t do anything but sit in the road. Just did a pico test and it “passed” but failed 3k miles after the recall was done.

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.

2023 Yukon xl denali passed the pico scope changed to 0w40 and 3 months later stopped working in the middle of driving just completely shut down. Engine started to smoke had it towed to dealership and they removed my oil filter and found crankshaft bearings in the filter. Needs a new engine now. Bought it brand new only has 45,000 miles on it currently.

The brake system control module, engine control module, and vehicle stability control system have repeatedly failed across 24 months and 9 repair attempts at two authorized GMC dealerships in tennessee. As of March 17, 2026 the vehicle has 27 active diagnostic fault codes including u160f and u1610 (brake system control module lost communication on both can buses), u1611 (engine control module lost communication), and c2a0a (vehicle stability control disabling inhibited). All components are available for inspection at beaman GMC in antioch, tennessee where the vehicle currently remains in an undrivable condition. Safety risk: vehicle has stalled on the highway with my family including young children in the car. Brakes have randomly engaged over 100 times with nothing around and also failed to engage when needed. Stability control is disabled. These are active safety failures confirmed by GMC's own diagnostic scans. The problems have been confirmed by both darrell waltrip GMC and beaman GMC across 9 visits. GMC's own technical assistance center (case xxx) was involved and could not resolve the defects. The vehicle was returned with more active codes than at drop-off after 57 consecutive days in GMC custody. Two unresolved GMC safety recalls are open on this vehicle — l87 engine loss of propulsion (n252494003) and brake fluid leak detection failure — directly related to the reported defects. Warning codes have been present and documented since October 2023 beginning at 1,381 miles. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

I just survived a terrifying incident that proves the current gm 6. 2l (l87) engine "recall fix" is a dangerous myth. Living with the "ticking time bomb" I bought my 2023 GMC Yukon at4 brand new, but for the last two years, I haven't truly "owned" it—it has owned me. Every long-distance trip with my family was filled with anxiety. I constantly worried that I’d be the next one stranded on the side of the road while my neighbors' and friends' 6. 2l engines were seizing all around me. I traveled with fear that I’d be coming home in a rental car. The false security of the recall when the recall finally arrived, I thought the nightmare was over. On sept 15, 2025, my dealer in newburgh, NY, inspected the truck at 48,000 miles. They told me my engine "passed," switched the oil to 0w-40, and issued me a 150,000-mile extended warranty. I realized then what I know for sure now: 0w-40 oil is a band-aid, not a cure. Gm used thicker oil to "cushion" a physical manufacturing defect in the crankshaft and bearings just to avoid the multi-billion dollar cost of engine replacements. They traded my family’s safety for their bottom line. The catastrophic failure last Friday, March 13, 2026, the "fix" failed. I was traveling 70 mph uphill on I-84 with my **newborn baby** and two other kids in the back. Without warning, the engine seized solid. I lost all propulsion in heavy traffic and had to fight to get my children to the shoulder. We sat in the freezing cold for over an hour while traffic flew by us. An extended warranty is worthless when your engine dies in a high-speed traffic lane with an infant in the car.
