I RECENTLY BOUGHT A 01 MUSTANG WITH 103K MILES ON IT. NOT 2 DAYS LATER THE PASSENGER SEAT BELT STOPPED WORKING. I TOOK IT DOWN TO OUR LOCAL FORD HOUSE AND THEY TOLD ME IT WAS JUST ODD THAT IT HAPPENED TO BREAK AND WOULD COST 300 DOLLARS TO CHANGE THE SEAT BELT. I DID SOME RESEARCH ONLINE AND FIND THAT MANY PEOPLE HAVE THIS PROBLEM. EITHER THE SEAT BELT LOCKS UP AND TAKES A WHILE TO STRAITEN BACK OUT OR LIKE MINE IT JUST STOPS WORKING. ONE POST ON A FORUMS SAID THAT HIS 2003 MUSTANG'S WENT OUT BEFORE 50000 MILES. I THINK THIS SHOULD BE CHANGED BY THE DEALER BECAUSE IF IT IS HAPPENING SO MUCH IT IS OBVIOUSLY A DEFECT. I HAVE A 95 THUNDERBIRD AND 01 ALERO THAT STILL HAVE THEIR SEAT BELTS WORKING PERFECTLY. THANKS FOR YOUR TIME ON THIS MATTER. *TR

I PULLED MY PARKING BRAKE AND GOT THE SAME RESULT. I THEN PUT MY CAR IN PARK AND AT THAT TIME I WAS DOING ABOUT 60 IN A NEIGHBORHOOD HEADING STRAIGHT FOR A LIGHT POLE. I JUST BARELY MISSED THE POLE BUT STILL HIT THE CURB AND TOTALED MY CAR. AFTER TURNING THE KEY THE ENGINE STOPPED. A MECHANIC AT THE COLLISION CENTER LOOKED AT MY ENGINE AND SAW THAT MY THROTTLE WAS STUCK WIDE OPEN. THE CAR IS STILL SITTING AT THE COLLISION CENTER WAITING FOR A FORD REPRESENTATIVE TO COME AND LOOK AT IT. *TR
THE LEFT DRIVER SIDE OF THE CAR CAME COMPLETELY OF AND FELL ON THE RIM AND BROUGHT THE CAR TO AN ALMOST COMPLETE STOP. *TR
