The SUV has 46,000 miles on it. Recently, the check engine light illuminated, prompting me to take it to the dealership for servicing. The diagnostic codes retrieved were u0285 and u1345. I was informed that the aero shutter required replacement. There was no physical damage; it merely ceased functioning. The dealership confirmed the active check engine light and conducted a diagnosis. While my safety was not immediately compromised, I felt extremely frustrated upon learning that gm would not cover the repair under warranty, despite this being a recognized issue that gm has yet to address. This situation is simply unacceptable and warrants further investigation and resolution.
I have a 2024 GMC denali that had an engine service appointment in September 2025 for the engine recall where they did an oil change & put in performance grade oil & scoped my engine. Rochester serra GMC said they sent all the engine pictures to gm and my engine was okay according to them. After that appointment in November my engine light went on and my denali was leaking oil in my driveway. We took the truck back to serra GMC rochester and they replaced the oil filter that they said was defective & an oil change was done after my husband requested that just filling up the oil was not okay. They also told us the engine light didn’t show up on their computer system and it must have cleared out, so nothing was done for that. Today 1/25/26 now about a month later my engine light is back on and has remained on with multiple starts. This is not acceptable and needs to be investigated and I want this escalated. I do not feel comfortable driving my truck with this engine light on with a known engine propulsion recall that has no actual cure. The oil replacement and cap change has done nothing and engine light remains on. I just don’t want to hear the same thing that the computer must have cleared the error code. My engine light is on for a reason and I’m asking for a thorough diagnostic test to be done by a certified technician and a get a valid explanation of why my engine light keeps going on & not just changing my oil or waiting for something catastrophic to happen to me or my family. Gm is putting me and my family at risk by saying that my truck’s engine is fine when clearly the engine light keeps repeatedly going on for 3 months in a row now since November 17, 2025.
****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 investigations into post-remedy failures (rq26001) and out-of-scope bearing failures (ea25007), I request that this incident be evaluated as part of the broader defect pattern analysis.
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 dealership stated the failure was a fuse block. After replacement the vehicle was test driven and stated to be operating normally. A second dealership employee test drove the vehicle, it died again and had to be towed back to the dealership. The battery was replaced after draining while disabled. Repeated mechanical and electrical failures resulted in complete loss of power at highway speeds and placed my children and me in immediate danger. I no longer believe this vehicle is safe to operate.
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.
On 15 Aug 2025, I was driving this vehicle on rte 151 in raccoon township with my 2 children when the vehicle suddenly and unexpectedly experienced a “loss of propulsion” with a corresponding uncommanded shift to “neutral”. Attempts to shift the car back into drive were met with a “parameters not safe” caution. I was fortunate enough that the vehicle behind me was able to slow and an accident was avoided. The thought that this could have happened with my family on the highway, during adverse conditions, or any other scenario is frightening to say the least. Other owners of affected models weren’t as fortunate.
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.

The engine of my 2024 GMC Yukon denali failed unexpectedly at 45 mph, shutting off without warning and shifting into neutral. My wife, three passengers, and two dogs were in the vehicle, which coasted to a stop. After several attempts, it restarted, and the check engine light illuminated. Alpine Buick GMC confirmed catastrophic engine failure, requiring replacement of the engine, radiator, hoses, and other parts. The vehicle remains at the dealership, and the failed components are available for inspection. This sudden shutdown posed serious safety concerns. My wife lost control over acceleration and power steering, increasing the risk of an accident. Had this occurred on a highway or in traffic, the consequences could have been severe. This raises concerns about the engine’s reliability and potential risks to other drivers. Alpine Buick GMC confirmed the engine failure and the need for full replacement. I am the sixth customer awaiting this repair, indicating a broader issue. The estimated wait time for an engine is two weeks to three months, creating a significant disruption. Inspection by manufacturer, police, or insurance the vehicle has been inspected by dealership technicians but not by GMC representatives, police, or insurance adjusters. I am open to further inspections to determine the cause and assess whether a recall or corrective action is necessary. No warning lights or symptoms appeared before the engine shut down. The check engine light illuminated only after restarting on the third attempt. The absence of prior alerts suggests a flaw in the vehicle’s diagnostic system. Expedited engine replacement – given the safety risks, I request priority replacement. Investigation into failure cause – GMC should assess whether this is a manufacturing defect. Review of similar cases – if widespread, a recall or service bulletin may be necessary. Better communication – regular updates on repairs and GMC’s actions are needed. I expect prompt action to resolve.
