Service Driver Assist System

I have a 2025 Sierra Denali. Starting about a thousand miles ago I began noticing that upon startup the dash would throw an error message: Service Driver Assist. When this happened, I noticed the OnStart button would display red and the SuperCruise would not work. When I would later restart the vehicle the message would go away 50% of the time. Is this an OnStar issue or an issue with the vehicle, for the dealer to look at.

    I also have a 2025 Sierra Ultimate Denali with the same issue. I am experiencing the same symptoms as gssmith1050. Is there a solution?
