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 Souther...

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.

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-...
