On [XXX], my 2022 GMC Yukon Denali XL (VIN [XXX] ) experienced a complete loss of propulsion while I was driving on [XXX] in El Paso, Texas, with my wife and two young children in the vehicle. Mileage was approximately 50,364. While in motion, the vehicle was displaying abnormal behavior, concerned the vehicle would stall on the highway, I exited at the Geronimo exit. As the vehicle slowed, it shut down entirely. Multiple restart attempts failed. The dashboard cycled on and off, displaying a "Service 4WD" warning while the vehicle was in 2WD mode. The transmission locked, and the vehicle became inoperable in the middle of the roadway with traffic passing on both sides. OnStar SOS was activated to communicate the unsafe location. The El Paso Police Department was requested to divert traffic. A city tow vehicle arrived after approximately fifteen minutes; my family was assisted across the roadway. Roadside assistance did not arrive for approximately three hours. This was the second loss-of-propulsion event on this vehicle in less than twelve months. The first occurred in March 2025 and resulted in engine replacement under NHTSA Safety Recall 25V274 (L87 Engine Loss of Propulsion). The [XXX] failure occurred after the recall remedy had been applied and the engine was replaced. The vehicle was towed to the dealer who replaced the throttle body, intake air duct and a service item titled "Repair open ground circuit". I am filing this report to document a second loss-of-propulsion event on a vehicle that already received the remedy under Recall 25V274, and to ensure NHTSA has visibility into the potential pattern of recurring or inadequate remedy on the L87 platform.

The current 6.2L engine recall was completed by Janssen Chevrolet in Holdrege, NE and it was noted the vehicle was fine. On April 11th, while driving down Interstate 80 in Nebraska, the engine suddenly died and would not restart. No warning lights or indicators illuminated prior to the failure and there were no symptoms. By sheer luck, it occurred before the head to head construction area with no shoulder and there was a rest area within coasting distance that and we were able to reach. I had little children in the car and we were stranded on the highway until friends were able to pick up the family and transport them to Lincoln and I was able to travel with the tow truck to deposit the vehicle at Husker Auto Group in Lincoln, NE. I was forced to rent a vehicle from a 3rd party as the dealer was closed and it was Saturday evening. On Monday, the dealer confirmed metal in the oil and filter and that the engine was completely dead and unable to be repaired, requiring replacement under the current recall. A much smaller loaner vehicle, insufficient to transport my family has been provided. It has been 13 days and there is no update on how long the vehicle will be out of service awaiting an engine.

I am submitting a complaint regarding a serious engine failure in my 2022 GMC Yukon XL equipped with the 5.3L engine (VIN: [XXX] ). The vehicle has experienced a complete failure of the lifters and camshaft. Prior to the failure, there were noticeable engine performance issues, including abnormal ticking noises, rough operation, and loss of power. The condition worsened rapidly, ultimately resulting in the engine becoming inoperable. This failure presents a significant safety concern, as the sudden loss of engine performance or power could occur while driving at speed, increasing the risk of a crash. The vehicle is currently not drivable and requires extensive engine repair or replacement. Given the severity of this issue and the potential safety risks, I am requesting that this complaint be formally investigated. I understand that similar issues have been reported in vehicles with this engine, and I believe this may indicate a broader defect affecting reliability and safety. Please let me know if any additional information or documentation is needed. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

What component or system failed or malfunctioned, and is it available for inspection upon request? The engine, battery and alternator seem to be failing or not working together. Car will sit in garage for less than 12 hours and will not start the next morning. Take the battery and alternator to get tested and everything passes. Have had the battery tested at multiple times but believe this is due to engine recall. Check engine light comes on, we take it to the GMC dealer and they say they can't determine the issue or why it is happening. How was your safety or the safety of others put at risk? Car will not start or check engine light comes on in middle of trip. Has the problem been reproduced or confirmed by a dealer or independent service center? Service center can't "reproduce" any of the issues and are telling us they have no way of checking why the light comes on in software module. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? Yes Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? Yes, check engine light comes on and then goes away.

While driving in traffic on a 2 lane road with small shoulders, the engine stopped, dash indicated automatic shift to neutral, restart vehicle. vehicle coasted to a stop partially blocking the lane due to lack of shoulder and size of vehicle. Turned off ignition and attempted to restart. there was a click and the dashboard/electronics all went blank/off for several seconds then came back on. Attempted this 4 times with the same results. Called GMC roadside assistance for a tow to the dealership. The vehicle could not be shifted to neutral due to not being able to start. The tow driver had to forcefully pull the vehicle onto the flatbed with the vehicle still in park. I do not know what method was used to get the vehicle off the flatbed tow truck. Vehicle was partially blocking the roadway for an hour before the tow truck arrived leaving me vulnerable to a high speed crash. And leaving the tow operator open to an accident during the 30 minute loading Upon diagnostic the dealer informed me the engine has seized/locked up. All recalls for loss of propulsion were completed at 48,711 miles on September 7, 2025 passing inspection and dealer performing an oil change to 0W40 oil. Engine failure was 3429 miles after the recall was performed with 52,140 miles. There was no warning or difference in driving characteristics prior to failure. There was not a loss of oil pressure prior to failure according to dash gauges.

My vehicle experienced complete engine loss while driving due to a crankshaft failure. There were no warning lights, no messages, and no indication of a problem. The vehicle suddenly lost all power in traffic and then the engine seized completely. This is extremely dangerous and could easily cause a crash. The dealership confirmed this is part of the known national crankshaft defect, but the replacement engine is on backorder for over a month, leaving me with an unsafe and unreliable vehicle. GM has replaced or attempted to replace the motor multiple times, and the defect continues. This truck should not be on the road. I am reporting this because it is a serious safety hazard to me and other drivers. A vehicle losing all power with no warning is a life-threatening defect

After getting the engine recall done on my vehicle over 6 months ago, I was driving down the highway at 70 mph last Saturday and without warning "Press Start" began flashing on my dashboard and I immediately began decelerating and my car put itself in Neutral. I was able to get to the side of the road safely. I was then able to turn the car off and back on. I was able to again accelerate into the road but once I reached 3/4th gear my car again began beeping with the "Press Start" warning and put itself into neutral. I was again able to coast on the side of the road to a stop where I called a tow truck to drop at my local GMC dealer. When roadside assistance showed up the car wouldn't even turn on anymore and I'm now being told that I need a full engine replacement even though I correctly completed the recall previously.

Car would not engage in reverse. Stranded and needed a tow into dealership. Also experienced rough shifting especially when accelerating in lower gears. Dealership said It needs a new Transmission Control Valve which is a known issue with my model and there has been a recall yet my specific VIN was not included in this recall!!! Dealer says the part needed is on backorder with no listed date of when it will be coming back in stock. Quoting me $3300 out of pocket to cover this repair once they can locate the needed part. No loaner car available and this is our main family vehicle!!! They called earlier to tell me they found the needed part at another dealer but it’s now going to cost me $600 more bc they had to buy it off the other dealership. What is happening!? This is not ok! My car should be covered under the recall!

On April 24, 2025, GM issued recall 25V-274 to address the concern with L87 engines produced between March 1, 2021, and May 31, 2024. GM cited the root cause as a supplier manufacturing and quality issues. GM’s recall remedy will be either an oil change to an oil with a different viscosity or engine replacement depending on the results of the remedy inspection procedure.
