2022 GMC Yukon Xl

Engine failure occurred while driving with two children in the vehicle, creating a serious safety hazard. The vehicle experienced a sudden loss of power and stalled completely while in motion, with no prior warning lights, alerts, or messages. Prior to this failure, the vehicle had already failed the GM PICO test related to the known L87 engine issue, and the recommended corrective action was changing the oil to 0W-40 synthetic and replacing the oil cap. Despite that intervention, the engine still failed at approximately 49,000 miles. A sudden complete engine stall without warning while driving created a dangerous situation, particularly with children in the vehicle. This raises concern that the prior corrective action did not resolve the underlying defect..

Recently my vehicle was serviced under recall N252494000 at an authorized GM dealership. Following completion of the recall remedy, which included an inspection and oil change to OW-40. As a result of this recall remedy, I have experienced the following adverse effects: •Significant increase in oil change costs from approximately $80.50 to $171.21 •Noticeable decrease in fuel economy (previously 18-20 mpg, now approximately 15-16 mpg). •Ongoing concern regarding engine reliability and safety •Diminished resale value due to the known engine defect and recall history. It is my understanding that this recall addresses a known defect involving internal engine components that may lead to catastrophic engine failure and sudden loss of propulsion. I am also aware that the NHTSA has initiated further investigation into failures occurring even after the recall remedy has been performed.

On April 12, 2026, while traveling approximately 65 mph westbound on XXX in [XXX] (just east of Exit XXX), the engine in our 2022 GMC Yukon Denali failed without any prior warning. This occurred on a four-lane highway where I was in the lane furthest from the shoulder. The engine shut off, the vehicle automatically shifted into neutral, and I had to cross multiple lanes of traffic to reach the shoulder without power steering while the vehicle was rapidly decelerating. I had my [XXX] son and [XXX] dog in the vehicle at the time, which created a significant safety risk. VDOT arrived on scene within minutes but was unable to jump-start the vehicle. I contacted Southern Buick GMC Kia in Greenbrier, VA and arranged for towing through their service. The vehicle was towed to their facility the same day. On April 14, 2026, the dealership informed me that the engine had failed and contacted GMC headquarters to order a replacement engine under the vehicle’s VIN. The vehicle remains at Southern Buick GMC Kia in Greenbrier, VA, where it is available for inspection by NHTSA. Previously, a PicoScope test was performed on October 7, 2025, under warranty code XXX. At that time, the engine was determined not to be eligible for warranty replacement; the oil was changed and a new oil cap was installed.

Engine failure with the 6.2 engine. My engine failed the Pico test in July of 2025 with 66k miles. The entire engine was replaced and I was told this would “fix” the engine issue. On April 25, 2026, my engine failed while I was driving at highway speeds. The engine was knocking and I pulled over as I could not accelerate it. I had it towed and was told by the dealership that the rod bearings failed and I would need an entire new engine. 9 months and 10k miles after a brand new engine was installed. This will be the third engine in this vehicle since I’ve owned it. GM’s “fix” for the 6.2 recall is not a fix. It’s pushing the problem down the road, risking lives by putting people in vehicles with known engine failures and no true fix.

I ordered and purchased this vehicle in November of 2021. Since it was new, it has consumed approximately one quart of oil per oil change interval as indicated on the oil life monitor system. Every time I have it serviced by the same dealership, I have inquired as to if this amount of consumption is "normal". They said it wasn't excessive yet to continue monitoring it. This vehicle did pass the recent engine recall inspection yet I'm still feeling as if there may be a problem that hasn't fully surfaced yet based on the initial recall.

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)
