My 2020 XT4 computer took a dump on me, For no particular reason it died at a stoplight and really started acting strange. When trying to start it the brake peddle pushed up, the wipers came on, the “Service Transmission” message came on the screen, the “low battery” message also came on, all the tires showed no pressure, the radio speakers started “thumping” very loud. I tried to reset the computer by disconnecting the battery ground like the internet said. Only made matter worse.
Am I the only one with this problem? I can get into my local Caddy dealer in a week !
