Over the last few weeks my BAS/ESP and skidding car warning lights have ben coming on here and the sometimes they stay on other times they don't ! When i press the ESP on-off button on the dash the skidding car would go off after to times of pushing the button ! never and the first try but the BAS/ESP would stay lit ! Last few days they stay on all the time ! Had a friend put a scanner on the vehicle and it showed performance brake switch ! did not mention any thing about speed sensor ! Just had the tires balanced and rotated the vehicle rides smoother then ever , just installed brand new ceramics all the way around ! Has any one had any of these issues ? and what did you do ? thank's wingslevel.
