I just bought a 2021 Yukon Denali with less than 5,000 miles on it. Before I even got it home, alerts started popping up. Steering assist, Service power steering, Trailer brake, Service traction control, Service Esc, etc. See video attached. I took it to Autozone and had them scan it. It showed 2 codes: P25A2 Brake System Control Module Requested MIL Illumination and U0139 Network Communication - Reserved by Document 13. I've taken it to 2 GMC dealers and both have shrugged and said "well it's not doing it anymore, so bring it back to us if it happens again." Well it happened again. 3rd time in less than a week.
I've uploaded a video.
Has this happened to anyone else?
