2024 GMC Yukon: engine stalls while driving

Filed Sep 29, 2026 · Engine · NY

My 2024 GMC Yukon Denali has experienced repeated and serious stalling, restart hesitation, shutdown, and loss-of-propulsion issues that have created an ongoing safety concern for me, my children, and other drivers. On one occasion, while I was actively driving with my children in the vehicle, the Yukon completely lost propulsion and died. I was only able to coast/roll the vehicle to a complete stop because it no longer had power. I previously reported that incident to the federal safety agency. Since then, there have been numerous additional occasions when I have been driving and come to a stop at a traffic light, stop sign, or in traffic and the vehicle has stalled or seriously hesitated before restarting. On September 23, 2026, while driving with my children in the vehicle, I stopped at a red light in heavy traffic. Without warning, the vehicle completely shut off, shifted into neutral, and displayed a message instructing me to restart the vehicle. I had to manually restart the Yukon before I could continue driving. This was the first time while stopped that the vehicle completely shut off, went into neutral, and required a manual restart. During these incidents, my children were in the vehicle and I was surrounded by other vehicles and heavy traffic, creating a serious safety concern. GMC has been repeatedly notified about these issues. Despite multiple complaints and prior repair attempts, the problems have continued and GMC has not provided a meaningful resolution. The cause of the most recent failure is currently unknown.

This is a supplemental report to my original complaint (the federal safety agency ID XXX) regarding my 2024 GMC Yukon (VIN [XXX]). I am providing additional detail: prior to GM's recall being issued, I contacted Hatchett Buick GMC by phone and visited in person on multiple occasions reporting engine sputtering, stalling, hesitation, and total loss of power and electrical shutdown while driving. I was repeatedly told these were minor issues not affecting anyone and not to worry about them. As a result, the vehicle was not formally serviced for these issues until September 2025 — roughly three months after the recall was finally announced, more than a year after I purchased the vehicle. Since that recall repair and a subsequent "best guess" repair performed by GM technicians (their own description, not mine), the vehicle continues to sputter, hesitate, stall, and intermittently lose power. I have ongoing safety concerns driving this vehicle INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

This report documents two separate safety incidents involving the same vehicle that occurred on different dates. Approximately one month prior to the most recent incident, while driving my young children to school, the vehicle experienced a sudden and severe loss of braking effectiveness while in motion. I was unable to stop normally at stop signs and had to roll through and roll to a stop. I was required to press the brake pedal fully to the floor to slow the vehicle, and even then braking response was significantly reduced and not functioning as designed. The engine remained running and the vehicle could still accelerate. After stopping and restarting the vehicle, braking function temporarily returned. On a later date, while again transporting my children, the vehicle experienced a complete loss of power while driving. The vehicle abruptly shut down while in motion. I was unable to accelerate and experienced loss of power assisted braking. The vehicle only came to a stop after coasting. Following this shutdown, a burning or melted plastic odor was present. The vehicle was later towed and inspected by a dealership. The battery was replaced; however, this did not resolve the issue. After the battery replacement, the vehicle later hesitated to start again. The exact cause of these failures remains unknown. These incidents occurred without warning and represent serious safety critical failures involving braking and propulsion systems. Both incidents placed my children, myself, and other motorists at risk. Had either event occurred on a highway or heavily trafficked roadway, there would have been little to no ability to safely slow or stop the vehicle, creating a significant risk of collision or serious injury. Due to these events, I no longer feel safe operating this vehicle and have stopped driving it. The vehicle remains available for inspection.

On March 21, 2025 my 2024 GMC Yukon Denali's engine died while driving 80 miles an hour down the highway with my family. We were able to coast to the shoulder. The vehicle would not restart. We called a tow truck. When the tow truck arrived the vehicle started but we decided to take the vehicle to closest GMC dealer. They ran diagnostics on the lights that were showing on the dash and nothing was reported. They had no recommendations. We were 3 hours from home returning from Spring Break so we decided to keep traveling. We made it about 120 miles and again the engine died while traveling 70+ miles on the highway. We were able to safely coast to the shoulder. We called a tow truck and the Yukon was towed to the local GMC dealership. The next week it was reported to me that the Yukon would need a new engine. The 1, 3, 5 rod bearing had spun and the 3rd trust bearing had spun. Since there were no rental cars in the city available we rented a U-Haul truck and drove 2 hours home. Almost one month later we are awaiting the new engine to be delivered.

The motor is randomly revving at braking so far only under 10 miles an hour. Yesterday it stalled twice on me and cut off braking under 10 miles an hour. I had to come to a complete stop while restarting the vehicle. Definitely has me worried if it happens on the highway or higher speeds.

On [XXX], I was driving approximately 70 MPH on [XXX] when the engine stopped without warning. I had the vehicle towed to Causley GMC where it was repaired. I was on the way home from Causley driving on [XXX] when the engine stopped again. I had it towed back to Causley. The next day they called me and said that the engine was destroyed and needed to be replaced. Both times it stalled I was on the expressway and if I were not able to coast to the side of the road, I would have been in a very dangerous position for me and everyone else on the highway. There was not a warning before the engine stopped, so it was very fortunate for me that I had enough momentum to be able to coast far enough to get in a safe position.
