This occurred from day 3 of ownership. Same issue so many others reported. Warnings constantly rotating on screens that trailer not connected, or lights burned out when not trailer even hooked up. This occurred when wet and cold. Service claims fixed with software update, but will have to wait and see once cold again in fall. This truck has many issues..... Lemon
