Hi guys!! Here is Korea.
First, I'm sorry about my poor English.
I have a problem with my 2023 Sierra1500 denali 6.2.
The C.C has not been working since yesterday. A.C.C neither of course.
When I press the cruise button, the instrument's icon is not displayed.
(As a message, switching to ACC or NCC works If I hold the button.)
Nevertherless, there is no warning messages from the truck.
That's what happened after using HDC(hill decent control) yesterday.
GM Korea lacks maintenance knowledge of Taho and Sierra. Because the sales period is short and the sales volume is low.
So please help me if you have any advice for me.
Thanks!!
