Error message in DIC shows "Service Driver Assist System"

[dasto]

Purchased a New 2024 CT4. Super Cruise & Lane Keep do not work. Called OnStar and they confirmed my account active and the highways were Super Cruise compatible. Set adaptive cruise and then Super cruise button but no white steering wheel icon appears. The DIC shows "Service Driver Assist System" at start-up.

I am experiencing the same issues with 2025 Sierra 1500 Denali Ultimate. DIC shows "Service Driver Assist System" at start-up and Super Cruise does not work. I have verified via OnStar app that account and services are active. When using Super Cruise I receive a message that no connection available. I am logged into Google and able to use Google Maps.

eejd : Is there a fix?

eejd: Does the Lane Assist button need to be on to use Super Cruise?
