So it was 43 below on the drive into work this morning, and about halfway in the Christmas tree lit up on the dash. It was showing me the ABS warning, Hill Assist warning and TCS off warning lights. I had this happen last year when it hit 35 below. The brakes seem to work fine, ABS and TCS are definitely offline when this happens. I put the car in the garage for a few hours and it was fine. Has anyone else had this type of problem or know what may cause/prevent it? Oh yeah '08 sedan, might need to put that in there.
