The front struts are going out on these vehicles. I know of another one that had the same issue and only had 38,000 miles on there Denali. This issue makes the front of the vehicle very stiff.

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.
