Waggs

blckblt, thanks for the info. I will check and make sure they are all pushed in. I have an appointment with the dealer tomorrow.

Purchased a 2021 Sierra SLT diesel on 6/1 and started it on the morning of 6/3 with remote start and the following happened. The infotainment screen was black no noise from radio, USB ports did not charge phone and turn signal does not make clicking noise. Has anyone had this happen do them.
