In my 2017 Chrysler Pacifica, purchased in December 2016, the Electronic Stability Control light always comes on when I drive faster than 50 mph and doesn't disappear even when I drive slower. It only shuts off when I turn off the car. The ESC light reappears when I start the car and reach about 50 mph. Just recently, the brake light on the dashboard will come on continuously soon after the ESC light comes on and doesn't disappear until I turn off the car. The parking brake is not on. Why do these lights signify. a problem with my electronic system?
