GMC Complaints

I was driving down the road, got a quick message. It said something about lean and to pull over (on dashboard). And by the next stop light the engine stopped. The truck no longer turned on. It did put my life in danger because it left me stranded in between two lanes. The truck was inspected by one of my mechanic friends who owns a shop. He let me know my engine is seized.

I possess a 2020 GMC Yukon XL. During multiple highway drives, I experienced a persistent loss of power. When accelerating from a stop, the vehicle struggled to shift gears smoothly, resulting in a rough, jerking motion. I opted to take the car to the dealership; however, before I could reach it, the vehicle lost all power and failed to change gears entirely. I am fortunate this complete loss of power and ability to change gears did not occur while I was on a busy highway. I purchased the car when it had 63,000 miles, and at 120,000 miles, the dealership informed me that the transmission had completely failed. A replacement of the transmission will be necessary.
