OnStar Light Red - Service Driver Assist Message - '25 Sierra 1500 Denali Ultimate

Ive had the same problem with the same truck. Also have had mt cruise increase speed with me realizing it. I mentioned it to the service center when had my first oil change and they pretty much blew me off and then at a different service center and they said “couldn’t replicate and no codes”. I thought this truck was/is GM’s best offering but Im not impressed. There are a couple other issues as well.
