I don't know why these light are all coming on at the same time, but it sure is making my Caddy run like sh*t. The mph went south really bad. The engine shakes around, and kinda vibrates when I'm driving. These lights are the traction, Stablizer, and the ABS. It also has that car with a squiggly lines behind the car light too. I reset them, but after a little while they all come back on. I don't know. It's just irritating.
