We are located in Henderson, NV and we were driving on the freeway in a construction zone with no emergency lanes when the vehicle lost all power to the engine going the speed limit. The engine had seized up which is a known problem with the 6.2L GMC motors. We have done all the recalls recommended by the manufacturer. The engine seizing, locking up , put our family in danger . We were luckily enough to be close to an offramp where people in other vehicles barley let us over so we can pull off the road or we would of been stuck in the middle of the highway with cars flying by us with little kids in the car. This is unacceptable and as much as this happening and GMC not fixing the issues, people are going to get hurt or killed. IT IS A HUGE SAFETY CONCERN! . ThIS is a known issue with these motors and problems and GMC is putting bandaids on the situations when lives are in danger. Our truck is a 2023 GMC Yukon Denali with only 53k miles on it

Took my Yukon in for L87 engine recall. Advisor informed me my engine failed. No symptoms, sounds or messages appeared.’
My vehicle was apart of the GM L87 recall. I took it to the dealership and it passed the recall and received the remedy which was an oil change. Now about 3 months later, I was driving in the highway at approximately 70 mph when the vehicle lost power and shifted to neutral. I had to attempt to veer off the highway with no acceleration. Upon getting it to the side of the highway, it wouldn’t do anything at all and had to be towed. The dealership has deemed it needs a new engine due to the failure the L87s are facing. We had no warning at all prior to the engine failure, and assumed that after passing a recall it had some degree of safety.
The vehicle drove fine had no warning/ check engine lights. My girlfriend came up to a busy intersection and when she proceeded to cross the intersection the vehicles motor locked up stopping the vehicle in the middle of the intersection with traffic coming from both north and south direction. We had poor visibility due to blowing snow so she had to bail from the vehicle and stand on the side of the road so she would not be harmed if the vehicle was t boned. Vehicle stopped so hard and fast it threw her into the steering wheel. Was unable to get the vehicle restarted and could not get it to shift into neutral so vehicle blocked 1 lane of traffic completely and half of another lane until tow truck arrived to remove from road.
In April 2022, I purchased a brand-new 2022 Yukon Denali from Roberts-Robinson Chevrolet GMC in Excelsior Springs, MO. Shortly thereafter, the first engine failure occurred in October 2022. The vehicle was towed to GMC AutoNation in Golden, CO, where it remained until repairs were completed in January 2023. Soon after the vehicle was returned, the second engine failure occurred in February 2023. The vehicle was again towed to GMC AutoNation, and repairs were not completed until April 2023. At that time, given the repeated failures, I worked with GMC and Roberts-Robinson Chevrolet GMC to replace the vehicle entirely. I took delivery of a new 2023 GMC Yukon Denali as a resolution. On October 8, 2025, the engine on the 2023 Yukon Denali also failed, marking the third major engine failure I have experienced across these vehicles. The vehicle was towed again to GMC AutoNation in Golden, CO, where it remained for two months. I picked up the "repaired" vehicle on Tuesday, December 9, 2025. This pattern of failures has caused significant disruption and distress. I have spent countless hours coordinating tows, securing rental vehicles, and seeking reimbursement for out-of-pocket expenses. More importantly, these repeated engine failures, all of which occurred while I was driving 65 MPH on I-70 through the Colorado mountains, have created extremely dangerous situations for me and my loved ones. Navigating heavy traffic during sudden engine failure and waiting on the roadside for assistance has been frightening and unacceptable for a vehicle of this caliber. Overall, this experience has been incredibly stressful and disappointing.
I brought my 2023 Yukon in for the 6.2 GM inspection, and was told my engine was good, and the engine oil was changed. Approximately 3 weeks later the engine in the Yukon failed (seized) while I was towing my boat at 55mph, nearly causing an accident. I was able to pull the vehicle and boat to the side of the highway in a precarious location, which put me, my family and property in danger. There were no warning signs or messages on the dash, and no engine sounds. I believe GM's recall inspection and "preventative" oil change did nothing, and gave me a false sense that the truck was safe to tow with. I want to make sure the federal safety agency is aware that the engine failed even after being screened with the recall. THIS FALSE REASURRANCE THAT THE TRUCK IS SAFE IS PUTTING THE PUBLIC AT RISK
I bought my 2023 Yukon Denali Ultimate on or around August 9 2023, and I bought it brand new. On May 28 2024, around 30k miles, I was on the highway and could no longer accelerate. I luckily got myself into the breakdown lane before my car shut down & lost power, ended up being towed to the closest dealership. After 18 days at the dealership, I finally had my car back with a "new engine". Fast forward to November 25, 2025, I was on the highway again, my dash lit up telling me to "press start". As i figured that was not a good idea while driving in the fast lane on the highway, I did not. in a panic I got myself over to the breakdown lane where my car turned off. This time (November 2025), I still had power, but no car turnover. After 6 days of my car sitting at the dealership, they finally had the time to look at the issue. The Dealership did the recall and got the car started, but the car still had a funny sound that the mechanics didn’t like , so they were waiting to hear back from higher up people as to what to do. Today I got the call that they will be replacing the engine for a second time and I will not have my car back until the first week of January. There were zero warning lamps, Zero Symptoms, nothing. I am Lucky that the Highway wasn’t too busy in that moment, because there were many 18 wheelers on the road that day, and one almost swerved into my car missing it by about two feet while my dead car sat in the breakdown lane. Yes I called the state police, Yes one trooper kindly pulled behind me to ask if I was safe and had a tow on the way. But that truck that nearly plowed into my dead car could have prevented me from picking my [XXX] [XXX] [XXX] daughters up from school, forever . To say that I am disgusted with GM, is an understatement. They’re risking lives. I should not fear for my life, my kids lives in a new, "safe" vehicle. No pun intended, but this is highway robbery.

GM has failed to resolve repeated issues on my vehicle (VIN: [XXX] ). I was never notified of any official buyback denial. GM Customer Assistance continues to avoid clarifying the status and refuses to provide documentation of the denial. This creates an unresolved safety and reliability concern. I need an investigation into the consistent mechanical defects paired with GM’s refusal to properly process my claim.

The vehicle engine experienced a failure on the highway at very high speeds with no warnings leading up to this occurrence, same as many of the experiences of the customers with the 6.2L engines, which have been recalled for these defects. This GMC Yukon has the 5.3L engine, however, has the same defects as the 6.2L engine, excessive oil consumption and eventually engine failure. I am without a vehicle, with an extremely high car loan, and have to replace an engine in a two year old $75,000 vehicle. This should be covered by GM as it was a known issue and continues to be sold to unknowing customers. Furthermore, I am paying even more money to put another engine in this vehicle with the potential of having the same issues as the problem has not been corrected. This is deceptive and theft by GM in my opinion, and not safe to have engines failing in the highway with no warnings at all.
I was driving down 85 South bound at mile marker 16 the engine started messing up causing me and my family to be pushed over to the median. Once I was able to fight it over to the median it started smoking and i was afraid it was going to catch fire, so me and my family had to get out on the side of the interstate until help showed up and said it was safe to get back into the car. I had to use OnStar to get a tow truck, after the tow truck got there and i made it to the closest dealership to find out that the so called recall that the GM dealership fixed did not help the fact that the engine was messed up. So i tried to get a loaner or rental car for my family of 6 and they rented me a small SUV that I can not get all my kids into, I was told they did not have anything that bigger so now I am having to make multiple trips getting my kids to school. Plus they are saying it is going to be months before I can get my car back because the engine is on back order.
my 2023 GMC Yukon Denali (VIN: [XXX] ), which is included in Safety Recall N252494003 for a known defect affecting the L87 6.2L V8 engine. My vehicle was first inspected under warranty in December 2024 at Serra Traverse City Buick GMC due to a burning smell. I was informed at that time that no issues were found. I was later told by the former service manager that the technician who evaluated my vehicle during that visit was let go due to poor workmanship and lack of product knowledge. Since that time, on two separate oil changes — January 8, 2025 and May 9, 2025 — my engine was found completely out of oil, with no oil on the dipstick. The documentation had to be retroactively added after my request. This pattern raises serious concerns about oil consumption or internal engine damage consistent with the recall defect. The dealership declined to replace the engine or perform any further diagnostics beyond the standard recall inspection. I was advised to retrieve the vehicle. However, I remain deeply concerned about the long-term safety and reliability of this vehicle, especially given GM’s acknowledgment that this defect may lead to engine failure and loss of propulsion. I have made multiple efforts to escalate this issue through both the dealership and GM’s customer service line. I was advised by Service Advisor [XXX] to contact the GM representative for regional review. He directed me to file a bbb claim.. Both GM and bbb denied my claim, stating out of warranty. However, the dealer explained that my issue were documented under warranty and would be handled appropriately if the issue persisted. GM contacted me an offered a $4000 credit. Unfortunately the problem still persist. I’m 3000 miles from being due for an oil change and again have no oil on my dipstick.

After stopping at a stop sign, I accelerated for a few seconds, but then it shifted to Neutral and the screen said "Press Start Again". I pressed Start, accelerated for a few seconds, and again it shifted to Neutral and the screen said "Press Start Again." I repeated this process a few times and luckily made it to the end of our driveway. I could no longer move the car nor could I shift gears. When trying to shift gears, the screen said "Conditions Not Correct for Shift." I requested Roadside Assistance. There is no way to get this car into neutral so he had to manually pull it onto the tow truck bed. The nearest dealership diagnosed it as engine failure and replaced the engine. There were no warning signs prior to this incident.
Recall issued in April states that the Engine could experience a catastrophic failure and needs to be inspected for possible replacement. At this time (8-30-25) they are not allowing the dealers to perform these inspections. Why can't they at least perform the inspection to see if in fact the Engine will not need to be replaced? They are being irresponsible with their approach to this issue.
The contact owns a 2023 GMC Yukon. The contact received notification of the federal safety agency Campaign Number: 25V274000 (ENGINE AND ENGINE COOLING); however, the part to do the recall repair was not yet available. The contact stated that while starting the vehicle there was an abnormal sputtering sound coming from the engine. Additionally, several attempts were needed to start the vehicle. The local dealer was contacted. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was not made aware of the issue. The failure mileage was unknown.
Driving on the highway and the engine completely shut down. The car was automatically placed into neutral and I coasted off the highway to a nearby gas station. The car was taken to the dealer, and they confirmed that it requires a brand new engine.
I am writing to formally express my concern and frustration regarding the prolonged delay in implementing a remedy for General Motors Safety Recall N252494000, which affects vehicles equipped with the L87 6.2-liter VB engine. This recall, issued in April 2025, was prompted by serious safety concerns involving sudden engine failure and loss of propulsion-conditions that significantly increase the risk of a crash. Despite the recall being acknowledged and a Special Coverage Bulletin (N252494003) issued in May 2025, there has been no clear timeline or actionable fix provided to affected vehicle owners like myself. The root causes, as identified by GM, include rod-bearing damage due to sediment and out-of-spec crankshaft dimensions-both stemming from supplier manufacturing defects. Given the severity of the issue and the number of vehicles involved (nearly 600,000), the lack of timely resolution is unacceptable. I urge the federal safety agency to take further action to ensure that GM expedites the development and deployment of a permanent fix. Vehicle owners deserve transparency, accountability, and above all, safety.
There is a safety recall but it has not yet been resolved, risking lives.

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

I am filing a complaint regarding my 2023 GMC Yukon Denali Ultimate, equipped with the 6.2L L87 V8 engine, which is currently under the federal safety agency Recall 24V‑266 for a potential engine failure due to defective bottom-end components. I received the official recall notice indicating that the issue poses a serious safety risk, including possible loss of propulsion and engine failure without warning. However, despite this being a mandatory safety recall, I’ve been informed by my dealership that no remedy is currently available, and I have been provided no timeline for repair or inspection. This effectively renders my $115,000 vehicle unsafe for normal use, yet I am left with no clear recourse, no loaner vehicle, and no repair timeline. I am now forced to restrict my driving to short errands only to reduce risk—completely unacceptable for a vehicle of this cost, class, and usage expectation. I am requesting that the federal safety agency formally investigate the timeliness and adequacy of GM's response to this recall and consider enforcing provisions of the Motor Vehicle Safety Act that require manufacturers to remedy defects within a reasonable timeframe. Thousands of affected owners are currently left without a fix for a potentially dangerous engine flaw. Vehicle: 2023 GMC Yukon Denali Ultimate Mileage: ~28,000 miles VIN: [XXX] Recall #: 24V‑266 (GM internal reference N232414720) INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
I was driving on the highway going about 50 mph and the engine just stopped. It was very dangerous, and I couldn't get to a completely safe spot. I was stuck for 45 minutes there until police could get to my Yukon and help provide safety. I had 2 other passengers in the car. All of us were put at great risk and the surrounding traffic was also at risk. The Triple A towing took over an hour to get the vehicle on a flatbed because they couldn't get the Yukon in Neutral. There were absolutely no warning lights or any weird noises, the car shifted out of drive and would not go back into any gear. I am waiting for the dealership to decide what to do. My main reason for writing this complaint is this is a BIG HAZARD, not only for people who drive/ride in these vehicles but for every vehicle on the roads around them. When they stop with no warning, accidents and I'm sure some with fatalities will happen. This is a critical situation, and these vehicles should all be off the road. My Yukon was in my dealership service for an oil change about 1 week prior to this incident and I had a long conversation about the recall. They said my Yukon looked great and nothing was needed unless I had any problems. Since there have been so many others with the failed engine, ALL vehicles with this recall should be off the road to prevent totally innocent people from being in these dangerous situations. This is preventable if these cars are forbidden on the roads!!! GM must take responsibility before lives are lost due to this negligent reaction of issuing a recall but saying it is safe to keep driving unless there is a problem. If the first sign of a problem is failure with resulting catastrophic outcomes, then just issuing a recall is not enough. This must be addressed, PLEASE. This was a terrifying experience for me and my riders. I have no idea if the police filed the report but they spent alot of time trying to keep everything safe due to this issue.

While traveling away from home with my son my vehicle said push to start. I was able to coast over to the side of the two lane highway and attempted several times to restart my vehicle. After several phone calls between two dealerships, I was told “If you can get it here we can help you”. So I had to file a claim with my insurance to have my vehicle towed to a dealership with only having service while the WiFi was operating. The tow truck kept getting pushed further and further back. Over 2 and a half hours later, keeping my son restrained inside the vehicle for safety, luckily an officer stopped and took myself and my son out of the 97 deg heat all the way to our destination another 2 hours away. From July to September my vehicle was in the dealership service dept waiting on a galactic back ordered 6.2 engine and main fuse repair.
Recall for engine propulsion. Say that there is no remedy yet. I have read the warnings about what may happen and I am terrified to drive the vehicle. GM says to contact the dealer, dealer says to contact GM. No one wants to take initiative. If they cannot fix the car, they should buy the car go back so I can get something different. I have been driving an old car around because I’m am afraid of this one. Please help me.
I own a 2023 GMC Yukon Denali with the 6.2L V8 engine. A safety recall was recently issued for this vehicle due to a potential engine defect that could result in sudden and severe failure. However, GM has not provided a remedy, and dealerships are unable to offer any repair or trade-in options while the recall remains open and unresolved. I live in a rural area with limited cell service and long distances between towns. This makes the potential for sudden engine failure even more dangerous. Out of serious concern for my family’s safety, I no longer feel comfortable allowing my wife or our [XXX] child to ride in or use the vehicle. The risk of being stranded—or worse, getting into an accident due to engine failure—is too great given our location and the nature of this defect. I attempted to trade in the vehicle at a GMC dealership to get into a safer and unaffected vehicle, but the dealer refused to accept it because of the recall. This leaves me stuck with a vehicle that has a known safety issue and no solution in sight, limiting both my transportation options and peace of mind. There were no warning lights or prior symptoms before the recall. The issue was disclosed by the manufacturer. A dealer has confirmed the recall is active, but no fix exists. This situation is unacceptable and has real-world safety and financial consequences for families like mine. I urge the federal safety agency to hold GM accountable and ensure a remedy is made available immediately to protect consumers who are left in limbo by this unresolved and serious safety defect.
