(1) I HAVE A 2003 BUICK REGAL WITH MILEAGE OF 17700.THIS MORNING AT 9 AM WHEN I STOPPED BEFORE THE TRAFFIC LIGHT IN THE INTERSECTION OF MOUND RD AND 13 MILE RD. (2) SUDDENLY THE BRAKE PEDAL APPEARS TO BE VERY LOOSE AND THE CAR STARTS GOING BACKWARD SLOWLY. I KEEP ON PRESSING THE BRAKE BUT THE CAR KEEPS GOING BACKWARD. I SWITCHED TO PARKING GEAR AND THEN DRIVING GEAR AND PRESS THE GASPEDAL AND THE CAR STARTS MOVING FORWARD. BOTH MY WIFE AND I WERE IN THE CAR. FORTUNATELY NO CAR WAS BEHIND US SO NO ACCIDENT OCCURED. (3) THE DEALER CHECKED THE CAR AND CAN NOT FIND WHAT IS THE PROBLEM. SO THEY ASKED US TO CONTINUE DRIVING UNTIL THE PROBLEM HAPPENS AGAIN! HOW CAN WE CONTINUE DRIVING A CAR WHICH ALMOST LED TO A FATAL ACCIDENT? THAT IS CRAZY!
WHILE TRAVELING AT 25 MPH IN TRAFFIC DRIVER APPLIED THE BRAKES AND THE BRAKE PEDAL WAS VERY HARD. AS A RESULT, THE DRIVER HIT ANOTHER VEHICLE. *AK THE AIR BAG FAILED TO DEPLOY DURING THE ACCIDENT. THE VEHICLE SUSTAINED $9700 DAMAGE BUT THE OTHER VEHICLE SUSTAINED NO DAMAGE. *NM
