My vehicle is equipped with anti lock brakes. The same system is used for traction control and stability control. My vehicle is prone to brake sensor failures. Whenever one of the sensors fails the onboard diagnostic system disables all 3 of these safety features. I currently have the third sensor failure since I have owned the vehicle.
