general problems of the 2024 GMC Yukon - part 1

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 identified by the recall. I understand NHTSA has investigated l87 engine failures occurring after completion of this recall remedy, including rq26001 and ea26005. I am reporting this post-remedy failure because it may be relevant to that investigation.

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.

Our Yukon was taken in for the recall. Dealer did the test and said it passed and used different oil. My wife and kids were driving to [xxx] from [xxx] yesterday. As they exited the highway, the car began acting weird. Then the car completely died. It was towed due to error code p0016. Dealer said they are going to put a new engine in. I saw online that cars with replacement engines were failing too? information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

The 6. 2 GMC engine has been replaced. I took my Yukon in for a oil change, on the second engine, the tech said that it now has a new oil synthetic 0-40, and I have to have the oil changed every 3 thousand miles. I checked with a couple of mechanics and they all said, synthetic is good for at least 5 thousand miles, and just thicker oil will not solve the engine problems that have plagued gm. I am bringing this to your attention as these vehicles are pretty much worthless in the marketplace, and as such gm should refund or exchange for the 2027, with the new motors.

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 interstate speeds presents a serious risk of collision, injury, or death.

I have a 2024 GMC Yukon denali equipped with the 6. 2l l87 v8 engine. The vehicle has approximately 23,000 miles. The vehicle previously underwent the remedy associated with the l87 engine recall. The engine now uses sae 0w-40 dexos r oil and has the corresponding 0w-40 oil fill cap. After the recall remedy was performed, the check-engine warning light began intermittently flashing while I am driving. The light may flash for a period of time and then turn off again. I have also intermittently experienced the engine running rough or the vehicle shaking while idling. I have noticed the flashing warning light occurring while the engine is under load, including while driving uphill. I have video documenting the check-engine light flashing while the vehicle is being driven. Because the condition is intermittent, the warning light is not necessarily illuminated afterward. I am concerned because this vehicle is equipped with the l87 engine that was subject to gm recall n252494000/NHTSA recall 25v-274 for potential engine damage/failure, and my vehicle appears to have already received the recall remedy. I understand NHTSA is currently investigating reports of l87 engine failures occurring after completion of that recall remedy. The cause of my vehicle's current symptoms is unknown and has not yet been diagnosed. The vehicle is available for inspection. I am filing this complaint because an intermittently flashing check-engine warning, rough/shaking operation, and the possibility of an engine malfunction or loss of propulsion present a safety concern, particularly if an engine failure occurs while the vehicle is being driven. I do have an appointment with a different GMC dealership for next week instead of the GMC dealership that sold it to me and preformed the original fix.

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.

Vehicle has 43k miles on it and a has a failed oil pump, already switched to the heavier oil and still have engine issue.

After having the recall inspection completed and changing to the recommended higher grade of motor oil, 0w40, my engine failed while driving on a major highway. We were traveling at high speed on a busy highway when the engine failed and the Yukon shifted into neutral leaving me little time to pull off the road. When the failure occurred the Yukon shifted itself into neutral and a message appeared telling me to press start again. I was able to get to the side of the roadway and called the state police for assistance. Six of us stood on the side of this major highway for 90 minutes waiting for a tow truck. Since the incident the engine has been replaced by the dealer but I am concerned that this may happen again. After the recall inspection they tell you that you are ok but clearly you are not, you are still in danger.

Driving about 75 mph car shuttered and motor quit running had to pull off of the highway and get towed to dealership. Motor had to be replaced due to 1,2,6,7 rod bearings spun on the crankshaft. 34367 miles.

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.

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 dealer; it reflects our belief that replacing the engine does not adequately address the circumstances surrounding this failure or restore confidence in the vehicle.

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.

I am reporting a serious safety defect and unreasonable delay in addressing it under safety recall n252494000 (l87 engine – loss of propulsion). My GMC Yukon has an illuminated check engine light and is now also overheating. According to gm’s own customer service r, this can lead to knocking, unusual engine noises, hesitation, high rpms, abnormal shifting, reduced propulsion, and sudden loss of propulsion while driving, increasing the risk of a crash. I have contacted multiple dealerships for urgent repair: cappllino GMC keller Chevrolet joe basil all three have advised me that they do not have enough technicians to get my vehicle in for repair. Each has urged me to continue driving the vehicle despite the active check engine light and recall, and all have refused to provide a loaner vehicle. I have also contacted GMC corporate directly for intervention. Instead of providing a loaner or expediting repairs, they have only offered post-repair rental reimbursement (up to $44/day after a repair order is opened). This leaves me with no safe transportation option. I have been told I can “drop off” the vehicle, but I have no alternative way to get home or to work. GMC and its dealerships are putting my safety (and the safety of other road users) at serious risk by directing me to continue operating a recalled, overheating vehicle with an active check engine light while refusing to provide any loaner or timely repair. My vehicle has 34,700 miles and is nearing the end of its warranty coverage, which raises additional concerns about potential delay tactics. Please review: the l87 engine defect and related check engine/overheating issues in GMC Yukons. GMC’s handling of this recall, including widespread failure to provide loaners and instructions to customers to keep driving defective vehicles. I authorize the release of my contact information to GMC to assist with the investigation. Attachments I can provide: screenshots of communications with GMC.

My 2024 GMC Yukon denali equipped with the 6. 2l l87 v8 experienced an engine failure on July 4, 2026. Prior to the failure, there was no visible damage, warning, or other evidence that the engine was about to fail. I drove the vehicle to purchase fireworks and shut the vehicle off normally when I arrived. When I returned to the vehicle after shopping, the engine problem became apparent. There had been no noticeable indication of an engine failure before I turned the vehicle off. The vehicle was subsequently taken to a gm dealership, where the engine failure was confirmed and ultimately required replacement of the 6. 2l l87 engine. The vehicle remained out of service from July 4, 2026, until it was returned to me on August 21, 2026. The original failed engine was in the possession of the servicing gm dealership I purchased the car from. Not even 8 months later of purchase the vehicle needed a 3rd engine (original, recalled engine, warranty engine). The lack of warning before the failure is a significant safety concern to me. The vehicle had been operating immediately before I parked it, and there were no apparent symptoms that would have alerted me that a major engine failure was imminent. Had the failure occurred while the vehicle was traveling at highway speed or in traffic, the sudden loss of engine operation could have created a dangerous situation. The failure was confirmed by the gm dealership and resulted in replacement of the l87 6. 2l v8 engine. I am submitting this complaint to document the failure and because of continuing concerns regarding the l87 6. 2l v8 and the effectiveness and long-term reliability of the recall remedy. I am still currently waiting for the repair work documentation for the new (assuming it was new) motor. I have attached attempts to talk to gm, app incidents, repair work being completed.

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.

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.

Engine locked up and seized traveling 75mph on interstate with only 28,000 miles.

The engine began knocking on startup and on acceleration. The vehicle would sometimes have difficulty accelerating. Upon taking it to the dealership, they were able to duplicate the issue. Upon inspection by the dealership, 2 rod bearings had spun and caused crankshaft damage. The manufacturer approved a full engine replacement under the warranty. There were no warnings lights, messages, or any other symptoms of the problem prior to the first incident.

This truck has the 6. 2 gm engine. While driving it late at night at approximately 28mph the engine blew, leaving the truck in the lane and unable to move. This was very dangerous since there was no warning and it just died. The truck receives regular maintenance by GMC and was tested to see if it was a “bad engine” and we were instructed that it wasn’t. Gm said it will take 4-8 weeks to get an engine and the value of the truck to trade in is very low due to “marketing issues” which in my opinion is their issue not mine. I am battling stage 4 cancer and just had an operation and need a car to go to the doctors. They have officially said that they don’t have a truck to loan me. This has been going on for years apparently and the government is not doing anything to rectify it for the us tax payers per my research. I need a truck and gm said that they would get back to me within 24-48 hours, we are way past that. What is the government going to do, these trucks are not safe. What if I was traveling late at night to snowmobiling and it blew, it would be a different story. Need some help.

At 35k miles our 2024 Yukon denali with a 6. 2l engine blew on a roadway with no known warning. Extremely dangerous situation with my pregnant wife and child in the car.

6/16 vehicle issues while driving home from work. Rough idle, multiple check engine lights coming on, multiple warnings display on dashboard. Vehicle in limp mode from work to home. 6/20 while driving in roanoke rough idle began. Vehicle check engine light appeared, limp mode only lasted for less than 30 seconds before it went back to normal. 6/23 vehicle issues began again while driving to work. Pulled into parking lot, turned vehicle off and restarted. Vehicle seemed back to normal. Made appointment through GMC app for first available on 6/29. Leaving work vehicle check engine lights came on again and went into limp mode. 26,764 miles. Drove straight over to hart GMC (2 miles away) and dropped it off. 6/30 picked up vehicle at hart GMC. Miss fire on cylinder #3. Replaced spark plug #3 and cleared all dtcs codes. 8/6 oil change with consumption test started 29,072 miles 8/28 engine oil low-add oil alarm. Instructed by dealer to not tamper with test. Must drive 2000 miles before returning vehicle to validate consumption test. 29,728 miles 8/30 pulling into drive way rough idle began. Vehicle check engine light appeared, limp mode, multiple lights. Scanned with obd2 scanner- p0303 code. Misfire cylinder 3. 8/31 vehicle towed from home to hart motors 29,860 miles. Scanned by service showing p0300 codes along with other codes. I have documented all events with this engine since owning. Concerned the engine would run out of oil before validating consumption test (2000 miles). Dealer told me to keep driving even if it says add oil. Engine historically 2 qts low when add oil warning flashes.

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.

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 on the highway. This vehicle has over 80% highway use.

Issues with the google voice, transmission issues, engine failure to start or restart. Reported same year vehicle was bought. Repeatedly. Dealership even with video evidence stated could not repeat issue and nothing wrong. My car then starts rattling in the engine and they do a full replacement had it for over three months. Now it’s leaking fluid and smoking. They try to send the consumer away and delay delay until the warranty is over. Unethical practices. They knew there was an issue with my engine as it was on the recall list but kept denying any issues until complete failure. Now less than 20 days after that repair the car is leaking and smoking.

This is a supplemental report to my original complaint (NHTSA id xxx) regarding my 2024 GMC Yukon (VIN [xxx]). I am providing additional detail: prior to gm's recall being issued, I contacted hatchett Buick GMC by phone and visited in person on multiple occasions reporting engine sputtering, stalling, hesitation, and total loss of power and electrical shutdown while driving. I was repeatedly told these were minor issues not affecting anyone and not to worry about them. As a result, the vehicle was not formally serviced for these issues until September 2025 — roughly three months after the recall was finally announced, more than a year after I purchased the vehicle. Since that recall repair and a subsequent "best guess" repair performed by gm technicians (their own description, not mine), the vehicle continues to sputter, hesitate, stall, and intermittently lose power. I have ongoing safety concerns driving this vehicle information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

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.

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.

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 vehicle. It has not been driven since. 6. Xxx — gm corporate case opened I contacted gm customer care and was assigned corporate case number information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

On our way home from vacation our engine failed and stranded us. This is the second engine that has failed and the vehicle only has 30220.

The contact owns a 2024 GMC Yukon. The contact stated that while her husband was driving at approximately 45–50 mph, the vehicle stalled. No warning light was illuminated. The driver pulled over to the side of the road, and the vehicle was towed to the dealer, where it remained for five weeks before being diagnosed. The dealer determined that the engine was blown and needed to be replaced. The vehicle was repaired at the owner's expense. The contact associated the failure with NHTSA action number: ea25007 (engine, engine and engine cooling). The manufacturer was notified of the failure, but no assistance was provided. The failure mileage was approximately 63,073.

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.

Complete engine failure, recall was performed before engine failed on highway with family inside.

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.

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.
