2024 GMC YUKON Complaints

Catastrophic engine failure while in motion. Clicking sounds while traveling 70 miles or more on interstate. Exited interstate and traveling 15-20 mph when vehicle came to sudden stop in roundabout. No lamps or alerts prior to failure. Vehicle would not transfer gears and was towed to Chevrolet dealership where diagnostic was completed. Engine replaced after 6 weeks but unknown if replaced engine is under recall.

The engine seized on us. It only has 18,000 miles on it. This could have caused a serious accident! There was no warning, no indication, it just died and would not restart. We had to have it towed over an hour to get to our closest dealer (and don't get me started on how they treated me!). We were stopped at a stop sign at the intersection and it just died. Thankfully we weren't driving down the highway or in the middle of traffic, we just ended up blocking people from using our lane for quite sometime. The cops were called for traffic control, but no police report was filed.

Engine started making noise no codes no alarms pulled off hwy had to have it towed to dealership. Service told us needed to replace engine had no time frame on when vehicle would be returned.

The contact owns a 2024 GMC Yukon XL. The contact stated that while driving at an undisclosed speed, the engine vibrated abnormally. There was no warning light illuminated. The contact received notification of NHTSA Campaign Number: 25V274000 (Engine and Engine Cooling); however, the part to do the recall repair was unavailable. The local dealer was contacted and confirmed that parts were not yet available. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was not made aware of the failure. The approximate failure mileage was 12,350. VIN tool confirms parts not available.

My vehicle stalled while driving on a busy highway & I had no option but to pull over, which left me & my family in a very dangerous position. Had to remove my daughter's wheelchair onto a tow truck as the vehicle had no power to use the hoist for her powerchair. Again, on the side of a busy road! Towed the vehicle to a GM dealership, who stated there was catastrophic engine failure & the engine had to be replaced. Had no way to transport my daughter until I got a new engine since her hoist was stuck at the dealership.

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.

Transmission will not shift out of 1st and 2nd gear. Backordered Valve Body Nationwide... none in the country. No ETA for this fix. Car has been in the shop over a month.

My engine quit in the middle of a intersection on 2-25-25 with approximately 20,777 miles and has been in shop waiting on a new engine ever sense and they can not tell me when the new engine will be in. I have call GM and get no time line on new engine.
