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?

Vehicle was brought to dealership Fountain Buick GMC 8701 S Orange Blossom Trail, Orlando, FL 32809 (866) 465-4364 for recall on engine.

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

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 NHTSA 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.

The Office of Defects Investigation (ODI) has received 1,157 reports of engine bearing failure failures in the L87 6.2L engine produced by General Motors (GM). Of the 1,157 reports received, 173 are outside of the scope of recall 25V-274. These engines are installed in Model Years (MY) 2019–2024 Chevrolet Silverado 1500 and GMC Sierra 1500, and 2021-2024MY Chevrolet Suburban and Tahoe, GMC Yukon/Yukon XL, and Cadillac Escalade/Escalade ESV vehicles. The subject engine failures were investigated as part of a Preliminary Evaluation (PE25001). GM determined that these engine failures were due to multiple supplier manufacturing and quality issues. GM issued recall 25V-274 to address the supplier manufacturing and quality issues produced between March 1, 2021, and May 31, 2024. Based on the issuance of recall 25V-274, NHTSA has closed PE25001. ODI continues to receive a significant number of reports of engine failure in vehicles outside the scope of 25V-274. This presents a potential safety risk that warrants further investigation.
