Hi All, I just purchased a 2021 Acadia SLT V6 on May 29th, 2021. Car currently has 175 miles on it. Driving home last night (day 2 of ownership) the entire instrument panel as well as the infotainment display went dark. I pulled over to a service station and kept the car running while playing with the dimmer switch.....Eventually the lights came back on. Defective dimmer switch? Why would the entire instrument cluster as well as the infotainment system go completely dark? Any TSB on this matter? I will be bringing the car into the dealer at my earliest convenience. Not thrilled that on day 2 of ownership my car has issues.
