THE PAST TWO WEEKS WHILE DRIVING THE VEHICLE, IT SUDDENLY TURNS OFF AND THE BRAKE LIGHT COMES ON FOR THE EMERGENCY BRAKE. IT IS SO SCARY WHEN DRIVING DOWN THE ROAD AND MY VEHICLE SUDDENLY STOPS. I HAVE TO PUT IT BACK IN PARK AND TRY TO GET THE EMERGENCY BRAKE OFF. IT TAKES A BIT TO GET IT OFF. THEN I CAN START IT AGAIN. I HAPPENED TODAY WHILE SITTING AT A RED LIGHT AND WHILE DRIVING DOWN THE ROAD. I WAS ON A CITY STREET.
