“I HAVE OWNED CAR SINCE NEW. ALL SERVICE PERFORMED BY SAME DEALER ON TIME. ALL REPAIRS DONE AS SUGGESTED BY DEALER. AIR BAGS RECALL PERFORMED IN 2006. NEW BRAKES WITHIN 6 MONTHS. DRIVING TO MY WIFE"S WORK (AIRPORT) ON SAME ROUTE FOR 38 YEARS (37 MILES FROM RESIDENCE). I OBSERVED RED LIGHT AND CARS STOPPED 100 YARDS AHEAD 1/4 MILE FROM DESTINATION. I APPLIED BRAKES SEVERAL TIMES TO NO AVAIL. I TOLD MY PASSENGERS THAT I COULD NOT STOP AND APPLIED BRAKES SEVERAL TIMES AGAIN. BRAKES DID NOT GO TO FLOOR. IT FELT AS THOUGH CRUISE CONTROL WAS ON - IT WASN'T. I AVOIDED A FEW CARS BY STEERING TO CURB AND SIDEWALK. I OBSERVED A LIGHT POST ON SIDEWALK AND HAD TO TURN INTO TRAFFIC HITTING TWO CARS. A MOTOR POLICEMAN WAS DIRECTLY BEHIND ME AND SAID NO BRAKE LIGHTS CAME ON. NO AIR BAGS DEPLOYED AND LEFT SIDE REAR PASSENGER'S SEAT BELTS FAILED. CAR WAS TOTALED. MY TWO PASSENGERS (MY WIFE AND HER CO WORKER) WERE TAKEN BY AMBULANCE TO HOSPITAL. *TR”
Structure

“THE CAR IS EQUIPPED WITH THE AUTOMATIC DOOR CLOSING SYSTEM, WHICH MALFUNCTIONED, CAUSING REAR SIDE PASSENGER DOOR TO BE INCAPABLE OF SECURELY BEING CLOSED. WHEN THE DOORS ARE SOFTLY PARTIALLY SHUT, THIS SYSTEM GRABS THE DOOR AND FINISHES COMPLETELY SHUTTING THE DOOR FLUSH TO THE OUTER BODY OF THE CAR. WHEN THE SYSTEM FAILS, THE DOOR CANNOT BE SHUT EVEN MANUALLY. IF THIS WERE TO HAPPEN WHILE ON A TRIP, THE DOOR WOULD FLOP OPEN AND CLOSED AND BE A SERIOUS HAZARD AND DANGER TO PASSENGERS, OTHER TRAFFIC AND THE POSSIBILITY THAT THE DOOR MIGHT COME COMPLETELY OFF THE BODY OF THE CAR. FORTUNATELY, IN MY INCIDENT, I WAS IN TOWN AND GOT TO A STORE TO PURCHASE ROPE TO TIE THE DOOR CLOSED BY STRAPPING IT TO THE OPPOSITE SIDE REAR DOOR AND TAKING IT TO THE DEALER FOR VERY COSTLY REPAIR.”
