My 2024 GMC Yukon XL Denali Ultimate (VIN 1GKS2KKLXRR331476, 6.2L L87) has been consuming engine oil excessively since early ownership. At the 20,219-mile oil change it was already a quart low, and it has needed repeated oil additions between changes since then. The vehicle is now at about 32,400 miles. I reported the problem in writing to the selling dealer on April 30, 2026, and again on October 9, 2026. GM opened case 115829578, but no oil consumption test or repair has been done. Low oil in this engine risks bearing damage and sudden engine failure while driving, the failure mode NHTSA is investigating under EA26005 for L87 engines built after Recall 25V-274's production window, which includes this vehicle.

2024 GMC Yukon XL Denali with approximately 30,000 miles. The vehicle previously completed the L87 recall remedy (NHTSA 25V274000). The dealer inspected the engine, it passed, and the higher-viscosity oil change, filter, oil-fill cap, and owner’s manual insert were performed. Despite that remedy, the vehicle later experienced a sudden loss of propulsion on the highway while traveling with family. The vehicle began shaking and the engine shut down. There were no check-engine lights, warning messages, or other notifications prior to or during the failure. The vehicle was towed to a GM dealer. Diagnostic testing at the dealer confirmed that the engine requires replacement under Special Coverage N252494003. The dealer indicated the replacement engine will be remanufactured. The service department also confirmed that the vehicle had been maintained in excellent condition and that all recommended services were completed as required, so the repair is being covered by GM at no cost to the owner. The prior recall remedy did not prevent a subsequent sudden highway failure with no advance warning. Once the current repair is completed, the vehicle will carry a permanent engine-related entry on its history report at low mileage, which will affect residual value. This complaint is being submitted to document the post-remedy failure involving sudden loss of propulsion on the highway with no warning.

Loud engine knocking. Told by dealer it was the 6.2 recall issue. Previously cleared as ok.

When stepping on the brakes out random the 63 mph speed limit alert along with service esc, front collision un available messages show on the dashboard and little by little the brakes stop functioning up until a point where brakes don’t work at all.

The contact owns a 2024 GMC Yukon XL. While the contact's daughter-in-law was driving 60 MPH, there was an abnormal sound coming from the vehicle before the vehicle shut off. The vehicle was restarted. While the contact's daughter-in-law was driving at an undisclosed speed, the accelerator pedal was depressed; however, the vehicle failed to accelerate 20 MPH. The vehicle was driven to the residence. The dealer was contacted and made aware of the failure. The vehicle was taken to the dealer where it was diagnosed with leaking fuel injectors. The contact was informed that the fuel injectors needed to be replaced. The vehicle was repaired. The manufacturer was contacted by phone and made aware of the failure. The failure mileage was approximately 39,744.

On September 17, 2026, at approximately 22,861 miles, the 6.2L L87 V8 engine in my 2024 GMC Yukon XL suffered a sudden loss of propulsion and was subsequently confirmed by an authorized GMC dealer to be seized and require complete replacement. I was entering northbound I-75 from the Mt. Paran Road entrance in Atlanta, GA with two of my children in the vehicle. This entrance has an extended acceleration ramp where vehicles accelerate to interstate merging speed. While accelerating, the engine briefly stuttered and then the vehicle stopped producing power when I pressed the accelerator. I was unable to continue accelerating and moved onto the limited shoulder. Other vehicles continued accelerating toward I-75 and passed immediately adjacent to us at significant speed. My children and I remained stranded there for approximately two hours waiting for a tow. The vehicle was towed to an authorized GMC dealer, which confirmed the engine is seized and requires complete replacement. The vehicle and failed engine are currently at the dealer and available for inspection. This vehicle was previously subject to NHTSA Recall 25V-274 / GM N252494000 for L87 engine failure and loss of propulsion. An authorized GMC dealer completed the recall procedure on November 3, 2025. The engine was not replaced; it passed the prescribed inspection and received the higher-viscosity-oil remedy. Despite completion of the recall procedure, the engine subsequently experienced the loss-of-propulsion condition

Update to original claim filed 11760897. Dealership inspected on 9/9/2026 and found engine damage severe enough to warrant a complete replacement. Catastrophic damage. Unspecified what caused the damage, but service advisor made me aware of a deep gash along the cylinder wall after removing the cylinder heads, unspecified cylinder. Likely from cylinder 3 where the code was being displayed- P0303. Vehicle was in the beginning stages of an oil consumption test and had a history of oil loss without any visible leaks. Add oil light came on 650 miles after oil change. Oil was likely being burnt up through combustion due to damaged cylinder wall. Unknown time for new engine to be installed. Estimated backlog 600 engines, could be regionally or nationally. Replacing engine at 29,800 miles, however vehicle has been having these issues much longer- closer to 20,000 miles. I want consumers to be aware this vehicle was not part of the national recall. Vehicle was manufactured in July 2024, two months past the recall date established for these GM engines.

2024 Yukon XL 6.2L V8 following a complete engine failure at 37,446 miles and the significant safety incident that resulted. On XXX, while traveling from [XXX] to [XXX] on [XXX], the vehicle suddenly lost acceleration while traveling at 65mph on a 2 lane HWY, displayed a Low Oil Pressure warning, developed loud knocking and ticking noises, and became inoperable. We were forced to drift to a stop in an isolated desert location after passing a highway sign stating “Next Gas Station 94 Miles.” Our family of four remained stranded for approximately 5½ hours in temperatures exceeding 100°F. During that time, we spent more than three hours working with OnStar, but no workable transportation or towing solution was provided. Ultimately, my mother drove approximately five hours from [XXX] to retrieve our family, and we arranged and paid for commercial towing ourselves. As the hours passed, our focus shifted from transportation to protecting our children from prolonged exposure to extreme heat. This concern was heightened because our youngest son has an underlying medical condition that affects his ability to regulate body temperature and has a single functioning kidney, increasing concerns about dehydration. Following delivery to Michael Hohl GMC in [XXX], the dealership documented the following findings: “Metal in oil.” “Metal bypassed oil filter.” “Need to replace engine.” We appreciate the professionalism of the dealership throughout this process. Our request is not directed at the

ENGINE FAILURE

On August 20, 2026, while driving my 2024 GMC Yukon XL Denali equipped with the 6.2L V8 engine at approximately 70 mph on the interstate, the vehicle experienced a sudden and complete loss of motive power without adequate warning. The vehicle unexpectedly shifted into neutral and would no longer accelerate or maintain highway speed. This occurred in active interstate traffic and almost resulted in a serious accident as I attempted to maneuver the vehicle out of the flow of traffic. The engine would not restart, and the vehicle had to be towed to a GMC dealership. The GMC dealership subsequently diagnosed that the engine had locked up and determined that the engine requires complete replacement. This failure created an immediate and significant safety hazard for me, my family, and surrounding motorists. My vehicle is affected by the 6.2L engine recall, and I am extremely concerned about the safety and reliability of the proposed replacement engine. I have become aware of reports from other owners alleging failures involving replacement engines as well, including similar sudden losses of propulsion. I am concerned that replacing the engine may not adequately address the underlying safety risk if replacement engines are experiencing similar failures. I am requesting that NHTSA investigate not only the original engine failure, but also whether replacement engines used as a remedy are adequately correcting the defect. A sudden engine lockup and complete loss of propulsion at inter

My vehicle "passed" the engine recall only to have the engine blow at 33,000 miles. My vehicle was at the dealership for 52 days most of the time was spent waiting for the new engine. Dealership was amazing, GMC however is the worst. My new engine has about 1,000 miles on it and it stutters occasionally when the auto start turns on.

On the freeway in the middle of nowhere Denali jerked, went into neutral, and stopped completely. Needed to get towed and it was complete engine failure. Dealership needed to completely replace engine and radiator

The contact owns a 2024 GMC Yukon XL. The contact stated that upon taking the vehicle to the dealer to be repaired under NHTSA Campaign Number: 25V274000 (Engine and Engine Cooling), the contact was informed that the vehicle passed the inspection and no repair was needed. However, the vehicle experienced engine failure approximately seven months later. While driving 50 MPH, the vehicle lost motive power. There was no warning light illuminated. The driver pulled over, restarted the vehicle, and resumed normal driving. The vehicle was taken to the dealer the following morning, where the Electronic Control Module was replaced under warranty; however, the failure recurred while driving 70 MPH three weeks later. No warning light was illuminated. The driver pulled over, restarted the vehicle, and resumed driving; however, the vehicle failed to exceed 40 MPH and shut off. The vehicle failed to restart and was towed to the dealer, where it was diagnosed and determined that the engine, radiator and seal kit needed to be replaced. The vehicle was not yet repaired. The contact was concerned that the recall remedy failed to prevent the failure. The manufacturer was notified of the failure and a buyback was requested, but the request was denied, and the contact was referred to the dealer for additional assistance. The failure mileage was approximately 27,800.

Driving on highway, engine stopped while driving 70+ mph. Had to get to the side of the multilane highway. Was towed to nearest GMC dealership. Dealer said the engine was locked up, and they have many vehicles right now with similar problems. They will have to replace the engine due to complete engine failure.

6.2 engine seized again after oil change 3 days after This is my 3 rd Yukon that has done this and I’m not agreeing this shouldn’t be a recall I’ve been through this before

We're in the waiting period for our 3rd engine. 1st engine failure, while driving on interstate at 70+ MPH, engine stopped running, causing a very unsafe condition for family and surrounding vehicles. Engine failure 2 days later, towed to dealership for inspection, replacement engine was installed ~4 weeks later. 2nd engine failure, while driving on interstate at 75+ MPH, engine seemed underpowered and would rev upwards of 6000+RPMs, not exactly unsafe, but not usual operating conditions either. Returned to dealer, upon inspection, total engine replacement was recommended.

Cameras go black and become inop randomly. Been in shop multiple times for concern. Software updates have been performed, modules replaced, cables, and now it’s back for the same concern.

Driving on highway at 80 MPH and accelerator stopped working and car turned off. We had to coast off toll rd and hope for the best. No warning and happened with our whole family in the car. I had a recall notice from manufacturer but last time I tried contacting manufacturer/dealer they said no resolution was available to repair recall yet and that I couldn’t drop off my vehicle.

I perform all maintenance on my vehicles, I have previously been a ASE Certified Master Technician, so I know engines and vehicles very well. Vehicle is outside of current engine recall window due to the engine build date being July 15, 2024. Engine was over maintained, oil and oil filter changed 6 times in 17,732 miles, first oil and filter change performed at 544 miles, when 5W30 oil was put in engine, installed a magnetic drain plug and installed Filter Mags on oil filter. Ran 5W30 oil for 2 oil changes, then moved to 0W40 oil. Oil analysis performed for each oil change. Results were looking acceptable up until the next to last oil change at 13,801 miles. Changed engine oil and filter on 6/12/2026 @17,732 miles. Found a heavy build up of metal particles on the magnetic drain plug and when oil filter was cut open there was a heavy build up of metal particles where the Filter Mags were located and the filter element had fine metal particles in entire engine oil filter element. The engine has made no noise and is still running, but based on the evidence the engine is currently failing and if I would have continued to drive it, the engine would likely lock up on the highway. CLEARLY GM DID NOT solve the crankshaft problem July 1, 2024 and CLEARLY using a higher viscosity oil like 0W40 will not keep these engines from failing. If I would have continued to drive the vehicle and if I would have not changed oil and found metal in the oil, this engine would have absolutely failed o

Vehicle started making a knocking noise. Made a service appointment. While on the highway, engine suddenly died causing the vehicle to shift into neutral. After stopping on the shoulder, vehicle locked into Park and would not shift back into neutral or start again for tow truck driver. Towed to nearby dealer who said the engine is beyond repair and has to be replaced. Estimated time to get engine and replace is 4 to 6 weeks.

2024 Engine failed while moving at 70mph out of state. De-accelerated rapid as I was changing lanes and was almost hit by two vehicles. Once of the interstate, I made it to the shoulder of an exit ramp that was a blind spot. Cars exiting to this ramp almost always had to veer to keep from hitting me. I purchased this vehicle in October 2024, never knew anything about a recall, was never disclosed to me about recalls. To this day, if I enter my VIN, there is no recall and I have never received any communication stating this vehicle was on recall. I complained to the dealer twice about unusual noise from vehicle, which they dismissed. I took it back to the dealer because my oil light indicated I was "low", this oil is too low, my concern was a leak. Took into GMC dealer, they stated we did not see any leak. Now this. Problem, GA law states in order to qualify for buyback, 24,000 miles or under 2 years. Well, I have 24,986...this automatically disqualifies me. SMH The options I was given are all a NO WIN for me! I was almost killed on the interstate, not to mention the level of stress and issues this car nightmare has caused me. $100k vehicle and I still owe 87K

1.XXX XX— GM Recall Notification (Recall No. N252494000) I received official notification from General Motors of Recall N252494000 affecting my vehicle. I brought the vehicle to [XXX] as directed to have the recall remedy performed. 2. XXX — First Report of Engine Propulsion Issues I reported engine propulsion concerns to Jim Ellis. This was my first formal complaint regarding the performance of the vehicle following the recall remedy. 3. XXX — Oil Type Change Performed by Jim Ellis Jim Ellis performed an engine oil type change, switching to 0W-40 oil, and advised me that this change would serve as the fix for Recall N252494000. I accepted this remedy in good faith. 4. XXX — Low Oil Warning Light Activated Approximately nine months after the recall remedy, and well before the end of the recommended oil life cycle, the low oil warning light activated on my dashboard. This is abnormal and indicative of excessive oil consumption. I returned to Jim Ellis, who performed a fresh oil change and placed my vehicle on a 6,000-mile oil consumption test — an acknowledgment that an oil consumption problem exists. 5. XXX — Active Engine Misfires, Jerking, and Flashing Check Engine Light While operating my vehicle on Sunday, May 31, 2026, I experienced severe engine jerking and misfires. The check engine light began flashing — not steady — which I understand to indicate an active and serious engine misfire event. I was genuinely concerned for my personal safety and immediately parked the ve

Engine failed- threw a rod Available for inspection Engine failed in the middle of a 6 lane interstate with 70mph speed limit. Locked up. Loss of power. No warning. Engine replacement needed- confirmed by dealer. This is the second engine replacement in less than 2 years Vehicle purchased in June 2024 Engine replaced June 2025 Vehicle taken to Glockner of Ironton Ohio in Aug 2025, Jan 2026, Feb 2026 and March of 2026 due to a knocking and ticking noise in motor. I was consistently reassured it was a normal sound per GMC. Engine locked up in the middle of the interstate may 15, 2026

First incident April 9 2024 not even a month after purchased. Vehicle dashboard lit up light a Christmas tree all warning lights while driving on highway. Vehicle shook and sputtered and turned off. The vehicle was serviced explanation given was loose spark plugs on a new vehicle. 2nd incident roughly month after recall repair for engine propulsion campaign. February 26 and 27 2026 . While driving the following lights came on Engine failure ,Brake failure , Service Transmission now unable to shift soon. I was terrified because I could not control the vehicle. I had the vehicle towed to the dealership. The answer to the issues was Battery failure. Third incident April 17th 2026 I driving on highway 70 miles check engine light comes on flashes dashboard goes dark. Vechicle sputters and shut down. I restarted the vehicle the warning on the display disappeared and the vehicle restarted. I reached returned the vehicle again to the dealership because the problem resumed slowing down even though I’m depressing the gas. Vehicle is shifting and dragging. Resulting unexpected lurching. My vehicle has been at the dealership since end of April 2026 it remains there currently. My representative stated a code indicating misfiring has appeared 18 times. Also everyday my vehicle keeps saying software update even I installed the update and it says complete. I know GM is not updating my vehicle software everyday. That indicates there is a computer issue as well. My anxiety level is through the

Had my oil changed Wednesday and noticed a new noise. Brought to dealership, this particular year is known for 6.2 L engine failure but was told mine wasn’t in the recall. Well I was told today I have engine issues and they are replacing

Purchase this Vehicle November 1st 2025 as a GM certified used vehicle. Had several issues with the camera system including the backup camera. Would go offline and not be usable for days. Vehicle went back to shop several times for this with no resolution. Now February 18th 2026 at approximately 630PM EST (after sunset) on the way into work traveling on the highway the engine lost power and engine shutdown. Vehicle shifted into neutral with the indication to press the start button in order to shift into Drive. This cause all of the lights to shutdown when it tried to start the engine. I was barely able to pull this over to the shoulder before I lost forward motion. Narrow shoulder. Tried to restart again with the same results. Call towing company. They attempted to jump start vehicle. Same results. All power shutdown. Truck was loaded onto flatbed and towed to dealership. Dealership states bad battery. Got authorization to replace battery from the dealer in which I purchased the truck. hey attempted to start and then it burned out the main fuse. They determined that the engine had seized and they were going to replace the engine. I looked up to find that GM had performed the engine oil replacement procedure in June of 2025. This vehicle is listed in the "recall" for defective L87 engines. Clearly changing the oil had no effect to remedy the issue. I have no faith that the new engine will not fail the same way this one did.

On March 14th the 6.2L engine was making a loud noise so I took it straight to the dealership and dropped it off. It was determined to be a failed engine. I have not been able to use my vehicle for 5 weeks now.

This is a Post-Remedy Failure of Recall 25V-274 (GMC 6.2L L87 Engine). Following a full engine replacement performed by the dealer under this safety recall, the vehicle has suffered a catastrophic electrical compromise. The vehicle is currently throwing codes P2534 (Low Ignition Voltage) and U3018 (BCM Communication). Safety Hazards: The vehicle experiences sudden loss of power, engine stalling at highway speeds, and total failure of the exterior turn signals (hyper-flash). The AC system has been disabled by the Body Control Module due to low voltage, creating a hazard in high temperatures. This vehicle fits the exact profile of NHTSA Recall Query RQ26-001 and Engineering Analysis EA25-007. The manufacturer's remedy for the safety recall has failed to restore the vehicle to a safe operating condition, and the dealership is attempting to charge diagnostic fees to investigate their own defective recall workmanship.

While driving I had a sudden loss of power. Contacted dealership and was ask for engine code light. Told them no light had appeared on dashboard. Did note intermittent shift changes while driving after this occurrence. Transmission and or engine feels like it has a studder. Concerning.

The contact owns a 2024 GMC Yukon XL. While the contact's wife was driving at an undisclosed speed, the accelerator pedal was depressed; however, the vehicle failed to accelerate as intended. In addition, the contact's wife noticed an abnormal knocking sound before the engine seized. The check engine warning light illuminated. The vehicle was towed to the dealer, where it was diagnosed and DTC: P0305 (lifter on cylinder 5); was retrieved, and the intake valve detached and damaged the camshaft. The contact was informed that the lifters and related parts, camshaft, and the coolant pump needed to be replaced. The vehicle was repaired; however, the failure reoccurred. The vehicle was taken back to the dealer where it was diagnosed with engine failure due to the metal shavings found in the oil. The contact was informed that the engine needed to be replaced. The vehicle was not diagnosed. In addition, the failure had occurred within 2,500 miles of the initial repair. The manufacturer was made aware of the failure ,and a case was filed. The failure mileage was approximately 14,589.

****This complaint is an addendum to ODI Complaint #11715415 **** This report updates the prior complaint to reflect complete engine seizure and pending engine replacement following post-repair loss of propulsion. I respectfully request that NHTSA include my vehicle’s failure in its ongoing evaluations related to L87 engine failures, including Recall 25V-274, Engineering Analysis EA25007, and Recall Query RQ26001. My 2024 GMC Yukon XL Denali experienced progressive internal engine failure beginning at approximately 61, 975 miles. First attempt: The vehicle required camshaft and lifter replacement due to internal mechanical damage. Immediately after 4.5 week repair, the vehicle suffered sudden loss of motive power at highway speed. The engine shut down without warning at 75 mph with children in the car. (Car was in owners possession for no more than 15 hours, and was driven 25 miles on the highway when it switched to neutral and shut down). Second attempt: The vehicle was towed back to the dealership. Additional electrical repairs were then attempted. (Fuse box) It shut down again during dealer testing. Third attempt: Subsequent internal inspection revealed cylinders 5 and 6 seized, requiring full engine replacement. This represents: • Repeated loss of motive power • Escalation from top-end failure to catastrophic lower-end seizure • Failure occurring immediately after dealer-performed repair(s) • A 2024 model-year vehicle with relatively low mileage Given NHTSA’s ongoing inve

About 4 weeks ago my vehicle began shaking uncontrollably while driving. The check engine light illuminated and multiple warnings appeared including emissions system, variable valve timing system, engine and transmission failures shown on the GMC app. I contacted the selling dealership and was given an appointment 4 days later. Later that day I drove less than 5 miles to pick up my children from school. During that drive the vehicle filled with a strong gasoline odor and exhaust fumes were overwhelming. I feared the vehicle could catch fire. I contacted the dealership again, stated the vehicle was unsafe, dropped it off at approximately 8:00 PM and was required to obtain my own rental vehicle. After one week I was told the engine required a camshaft and lifter replacement. Inspected & approved by extended warranty, parts were ordered and installed. I retrieved the vehicle on 23 days after the initial failure. The following morning (24th day) while driving approximately 75 mph on a major interstate with my children the vehicle suddenly shifted into neutral and would not re-engage. I was unable to shift into any gear and coasted to a narrow shoulder inches from traffic and guardrail.The dashboard stated the vehicle could not shift into gear and instructed me to push the start button. The engine would not restart. We were stranded approximately two hours in 10-degree weather on a major interstate with heavy semi-truck traffic. Roadside assistance was required. 3 days later the d

I am filing this complaint regarding a serious and ongoing safety issue with my GMC Yukon Denali that began with a complete engine failure while driving on the highway with my entire family in the vehicle. While driving at highway speed (about 60–70 mph), the vehicle suddenly lost power and shifted into neutral on its own. While still moving, I tried multiple times to shift back into Drive so I could safely get off the road, but it would not engage. I was only able to coast partially onto the shoulder before the vehicle came to a complete stop, still partly exposed to traffic. The engine shut off and would not restart at all. It would not go into Drive or Neutral, and the vehicle was completely dead. And it had to be towed. The dealer later told me the engine had failed and that a new engine was installed. About a week later, I picked the vehicle up. Less than 20 minutes after leaving the dealership and getting back on the highway, smoke started coming from the vehicle and warnings appeared, messages that the engine was overheating and that I needed to stop the engine immediately. The vehicle was not drivable again and had to be towed back. I again had to arrange transportation home. A few days later, I picked the vehicle up again. Since then, I have had serious four-wheel-drive and drivetrain issues. The vehicle became stuck in 4 Low and I could not get it out for over a day. When it finally came out, the drive mode buttons stopped working correctly. Selecting 2 High sometim

Transmission appears to be lunging and shuttering. Dealer has indicated that the valve body need to be replaced or the vehicle could leave me stranded or without propulsion while driving. From my research this appears to be related to other safety recall and service campaigns for this type of vehicle and the transmission that I have in my vehicle. Also the camera system doesn't work correctly as it relates to parking assist and collision control. My repair dealership has stated they are having trouble getting GM to cover this repair.

Good morning. It’s about the safety recall for loss of propulsion due to manufacturing defects that can lead to engine damage and engine failure. GM notified me about this in September 2025 . So, I drove my vehicle to the dealership to inspect my vehicle , my SUV passed the examination, they replaced the oil recommending now another one with higher viscosity, new oil cap and an owner’s manual insert free of charge. Ladies and gentlemen; My concern from here on now is, just doing this is going to give me a peace of mind? Meaning the manufacturer defects issue is not longer in my vehicle? I paid a top dollar for this specific unit because I like to travel across the country even to go to Mexico. Right now I’m driving the truck silent, no music at all.driving the vehicle just to go to the store, to buy groceries,very short trips, around my neighborhood Trying to hear any noise, any knocking noise on my engine, observing the dashboard controls constantly, my family and I decided to stop traveling due to my vehicle is not secure to do it with this particular 6.2 engine because my notification letter from GM says that if the vehicle fails during operation will lose control increasing the risk of crash. As a GM customer, using my vehicle with my family I don’t feel safe and comfortable with my vehicle therefore I am asking and expecting for a better solution from General Motors. Not just replacing the oil for another one with a higher viscosity because doing this only is telling me

My vehicle failed the Picotest that GM is conducting on the engine. It is currently sitting at Romain GMC in Evansville Indiana. I am not sure if I was at risk but the dealership says it's unsafe to drive so my assumption is that my safety was at risk. The dealership states that it will take 3 months before a new engine is installed. There were no symptoms leading up to this recall inspection.

The contact owns a 2024 GMC Yukon XL. The contact stated that while driving at 70 MPH on the highway and attempting to accelerate around a possible drunk driver traveling on the roadway, the vehicle failed to respond as needed. The driver was able to pull over safely. There were no warning lights illuminated. The contact called 911 and called for Roadside Assistance, and the vehicle was towed to a local dealer, where it was diagnosed with an engine failure. The vehicle was not repaired. The vehicle was previously taken to the local dealer to be repaired under NHTSA Campaign Number: 25V274000 (Engine and Engine Cooling). The manufacturer was contacted, but no assistance was provided. The failure mileage was approximately 32,000.

I was driving on interstate and thank God I got off the exit and vehicle suddenly cut off. An indicator came on stating to push start to restart vehicle while the vehicle shifted to Neutral on its own. Then a Low oil pressure sign came up on dashboard. I tried push start again and nothing happened. Lucky by this time I was just off the exit so I was able to come to a stop and shift to Park. I tried push start again and the dashboard just went dark and started making a clicking noise. After some time around 1 min I tried again and it did crank up and I was able to try and get as close the the edge as possible but still in a two lane road on the bridge of an off ramp. I say thank God because 30 seconds sooner I was going around 60mph with my 4 month old in the backseat. Lucky I got to the exit when this happened. From the research I have done apparently this happens a lot to this model I have 2024 GMC Yukon Denali XL. I had a recall for this issues supposedly fixed back in October 2025. Things could of been much worse. Also this all happen coming from just having an oil change done at the dealer. Literally leaving the dealership going home. The dealership loaned me a vehicle they say for 3 days for free after that I may have to pay because it may not be covered by GM which is ridiculous. The vehicle is at the dealer and I will be waiting to hear there analysis.

Vehicle parked for extended period, 7-10 days, entered vehicle on 12/05/25 and proceeded to start - immediately service transmission appeared in display, check engine light on, dash flashing and door locks going up and down and chiming of alarms. was able to place in reverse, backed up, put into drive and vehicle would move approx 5-8 ft, lock up and stop, start again and repeat, etc.. put vehicle in low1 was able to get back in driveway and parked. had vehicle towed to closest dealer who had a transmission specialist available and worked with GM warranty plus GM CarBravo warranty to address issues (multiple dealers refused or didn’t have available personnel and/or were multiple weeks out for repairs). called and advisor said i needed a new battery (22mo of a 36mo free battery replacement GM AC Delco) and to have transmission valve body replaced and no tcm, 3-5 days for part delivery and that this was under a GM Service bulletin # PIP6069 (which i pulled up online), stated this repair (valve body) fixed most vehicles but knew of a few instances where complete GM 10spd transmissions had to be replaced. glad this happened in my driveway versus while being on a long distance trip. waiting on part delivery and unable to use vehicle due safety issue with transmission.

Vehicle was operating on the interstate with cruise control activated. Time was approximately 9:15pm. Weather was fair with temperatures in the lower 60's. Speed was approximately 73mph. Without any audible or warning light notifications the engine stalled and all exterior lighting, power assisted braking and steering was lost. The emergency flashers were immediately activated to warn vehicles in nearby proximity of our emergency status. I tried to restart the engine(the transmission was showing to be in N)with no success. During the attempt to restart, the exterior lighting was restored. With the path of travel now visible, I was able to slow the vehicle to a safe speed and exit from the roadway onto the shoulder. Upon stopping, the vehicle was placed into P and OnStar was notified of the event. We remained in the vehicle until one of our friends was able to take us home. Onstar contacted AAA to remove the vehicle to the nearest GM dealership.

ChatGPT said: There is a design flaw with the automatic light function. When you turn the knob to disable the automatic lights to avoid blinding someone while parked, the knob returns to the auto position as expected. This is a good system to ensure that the next time you start the car, the lights are in auto again. The issue is with the way the system indicates what is happening to the driver. When the lights are set to auto, the “auto” indicator on the knob is illuminated. If you turn the knob to running lights or full lights, the corresponding indicator lights up as expected. However, when you turn the lights off, the indicator light returns to “auto” even though the lights are actually off. While the physical knob should return to auto to make sure the system resets properly at the next startup, the indicator should switch to the “off” position so the driver knows the lights are off. I drove off in the city and assumed my lights were on because the knob said auto, but I later realized they were off. This creates a serious safety hazard. There is no way to know in that situation if your lights are actually on by looking at the knob unless you cycle the lights again. A recall should be issued to change the software or replace the button to make sure that this is clear to the driver.

I am filing this complaint regarding GM Recall N252494000 (NHTSA Campaign Number 25V274) for my 2024 GMC Yukon XL (VIN: [XXX] ). The issue involves a serious engine defect related to the crankshaft and/or connecting rods, which can result in catastrophic engine failure and loss of propulsion while driving—a clear and dangerous safety risk. I first became concerned when early reports of this issue began circulating publicly. As a father of young children, I became increasingly uneasy that my vehicle could potentially fail while in operation. Receiving GM’s formal recall letter only validated my growing concern for my family’s well-being. It’s deeply frustrating and unsettling. The notice states that parts to repair or replace the engine are not currently available, and offers no clear timeframe for when a remedy will be provided. I feel like we are being strung along while forced to continue using a vehicle that may become unsafe at any moment. This delay is unacceptable. There has been no offer of a loaner vehicle, no proactive communication from the dealer, and no assurance from GM that they are prioritizing driver safety over logistics. I am requesting that NHTSA investigate whether GM is doing enough to provide timely remedies to affected customers. I also urge you to consider whether interim solutions (such as alternative transportation or more aggressive recall execution) should be mandated. Thank you for your attention to this matter.
