None of my Driver Assist features work on my brand new 2024 GMC Denali pick up

I have a 2024 gmc sierra 2500 hd, had an issue where I couldn’t shut it off accessories mode, this caused the batteries to completely drain. Since this both my lane departure and front crash sensor do not work. Dealer says it’s because the truck is lifted, even though it’s worked great with the lift for 2 months prior to this incident. Crazy part ever is if I spray windex/water on the front camera and side mirrors and wipe them, then start the truck all sensors work fine for that ignition cycle until I turn it off. GM doesn’t know what to do and refuses to do anything because it’s lifted even though clearly it’s not because of the lift, not trying to spray my cameras every time I go to drive!
