WHILE DRIVING IN THE EXPRESSWAY OR ROAD THE CAR WILL SUDDENLY SHUT OFF. ALL OF THE LIGHTS WILL COME ON IN THE DASHBOARD AND I HAVE TO PUT THE CAR IN NEUTRAL OR PARK TO START IT BACK UP. IT WILL ALSO SHUT OFF IF I'M TURNING SLOWLY AROUND A CORNER OR IF I COME TO A COMPLETE STOP AFTER DRIVING FOR AWHILE.
