2021 Colorado ZR2 - Was driving through town the other day and all of a sudden the dash said "Engine Power is Reduced", the check engine light came on and it started running really rough. Limped it to the dealer and they pulled 16 different codes. First time I've had any issues or codes. I know it's an electrical issue but don't quite know where to start. Any suggestions? Thanks!
