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.
