The abs, hill assist, and the red triangle randomly come on, at this point, the truck stops downshifting by itself when slowing down or approaching red light,have to do it manually. Upshifts fine. When I turn the truck off and turn it back on, the lights go away, but come on sooner or later... pull different trailer every day. 3rd day with this problem. 2017 cascadia day cab single axle automatic

Sounds like a brief loss of power to the ECM, or the abs ECM.
