DRIVING NORTHBOUND ON HIGHWAY 116. VEHICLE IN FRONT OF ME STARTED TO SLOW DOWN AND SLIGHTLY PULLED OFF TO THE RIGHT OF THE HIGHWAY. AT THE TIME BEFORE THE CAR IN FRONT OF ME STARTED TO SLOW DOWN I HAD THE CRUISE CONTROL SET AT 70 MPH WHEN THE CAR IN FRONT OF ME STARTED TO SLOW DOWN. I SLOWED DOWN TO ABOUT 60-65 MPH AND PULLED OFF THE ROAD SLIGHTLY. THERE WAS A SEMI TRUCK TRAVELING SOUTH BOUND ON THE HIGHWAY I THOUGHT EITHER THERE WAS SOMETHING IN THE ROAD AHEAD OF THE CAR IN FRONT OF ME OR THE TRUCK WAS IN OUR LANE. THE ROADS WERE DRY AND THE SUN WAS COMING UP. AS I BEGAN TO COME BACK ON THE ROAD MY RIGHT FRONT TIRE WAS FEELING WOBBLY AND I EITHER HIT THE CURB ON THE BRIDGE OR A PIECE OF METAL CAUSING ME TO LOSE CONTROL OF THE VEHICLE. I RAN HEAD ON TO THE SOUTHBOUND SIDE OF THE BRIDGE THEN STARTED SPINNING AND HITTING THE BRIDGE SEVERAL TIMES. I FINALLY ENDED UP BACK ON THE NORTHBOUND SIDE OF THE BRIDGE ABOUT 3/4 OF THE WAY DOWN THE BRIDGE. WITH MY FRONT END HITTING THAT SIDE OF THE BRIDGE. WHAT CONCERNS ME IS THAT MY AIR BAGS NEVER DEPLOYED IN THE VEHICLE AND I SUSTAINED NECK, SHOULDER AND RIGHT KNEE INJURIES. AT THIS TIME THE VEHICLE IS AT A LOCAL BODY SHOP WITH THE INSURANCE, AND COMPANY THAT MAKES THE VEHICLE INVESTIGATES THE DAMAGE. I HAVE FILED A COMPLAINT WITH SATURN LETTING THEM KNOW THAT I BELIEVE THAT THIS IS A PRODUCT DEFECT. *NM
