      I have 2020 Yukon XL Denali and have 5 things that either work or don’t work all at the same time.
      Before I get into the vehicle I try the lift gate if it works then the other 4 will work. If the lift gate will not open either by key fob or button then when I get into the vehicle then the following also won’t work.
      1. Lift gate
      2. Rear Air
      3. Rear wiper
      4. Blind spot indicator on my mirrors
      5. Side detection air bags need service light comes on
      These will not work until I shut the car off and leave and come back later and try it again.
      It’s like a flip of the coin if they work or not

      Those sound like serious issues. Take it back to the dealer for a warranty.
