Service Drivers Assist

I bought a 2026 GMC Sierra 1500 Denali in December of 2025. At 200 miles service drivers assist came on and will not turn off. I have owned the truck for 7 months now and all GM will tell me is they are aware of the situation and a fix is coming. I currently do not have lane assist, front sensors, automatic hi beams or cruise control because of this error. i currently have a 70K truck that does not function like it should. Cant sale it because of the driver assist problems that GM wont fix. I have been a loyal GM fan my whole life but after this i will be looking at other options.
