This vehicle was identified as recalled in 2025 for total engine replacement and the engine did fail in May 2025 it would stall while driving. GMC performed the engine replacement in June of 2025. The car stalled again on Friday May 1. It was taken to the dealer on May 7 and was diagnosed as needing another complete engine replacement. I was told that gmc identified a need to replace more parts after my engine was replaced but I was never informed of this. I was told my this dealership that I am the first vehicle they’ve seen that will require a second full engine replacement It is a 6.3L v8. This car stalled while I was driving with a 3yo in the vehicle.

My 2023 GMC Yukon Denali is currently at the dealership due to a manufacturer recall involving the engine. The engine issue occurred while I was driving with my children in the vehicle, which required me to pull over and have the vehicle towed to the dealership After inspection, I was told the vehicle requires a full engine replacement. The dealership has stated there is no estimated time of arrival for the replacement engine due to backorder, and that other customers have been waiting for extended periods. I am currently without my vehicle and have been provided a temporary replacement that is not comparable. The extended delay and lack of timeline are causing significant loss of use.

I was on the highway heading home with my [XXX] son in the backseat and without warning the engine shut down and luckily we were on the exit ramp and away from heavy traffic. I pulled over to the side and tried to start it again but it won’t even crank. The cabin heater stopped working too, It was -9 Degrees outside that day and we started to freeze, luckily my wife was able to get to us in 20minutes. The vehicle was towed to GM dealership and they confirmed the engine seized and will need a new engine under special coverage N252494003-03. This was after the recall was completed for this vehicle. It had only 61392KMS on it. We live in [XXX] and it gets extreme winters with below -40degree temperatures. It’s a remote area and there is no service on the highway for 200KMS when heading south to city, if this would have happened on the highway with no services and extreme weather we wouldn’t have made it out alive. We are a family of 5 with a [XXX] and a [XXX] and we bought this vehicle after knowing that the engine recall was completed and GM deemed it safe. Unfortunately that’s a lie and GM is putting peoples safety and life at risk. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

on 2/28/26 i experienced complete engine failure on my 23 Yukon. I was going 70mph on the highway when the engine kicked and and kicked into neutral. the car spent 6 weeks in the dealer to have the engine replaced. i picked up the car on Wednesday, 4/15. On 4/16, i was once again driving, as normal when it suddenly turned off and kicked into neutral. 1 day after I picked up the vehicle it is once again being towed back to the dealer for the same symptoms it had when the entire engine had to be replaced. Both times, there is no warning. The car dings and a message comes up saying "restart vehicle". On 2/28, the car would not restart. On 4/16, the car did restart but only temporarily This is a major safety problem. The first occurrence I was going 70mph on the highway when i lost power. The second occurrence, I was driving 20mph on my neighborhood street and suddenly lost all power.
