DRIVING DOWN THE I75 EXPRESSWAY IN HEAVY RAIN SPEED AT THE TIME WAS APPROX 60 MILES PER HOUR, DECIDED TO GET OF AT THE NEXT EXIT UNTIL THE RAIN COOLED DOWN. I THEN TURNED BY STEERING WHEEL SLIGHTLY TO THE RIGHT TO MERGE ONTO THE EXIT LANE WHEN THE CAR INSTANTLY STARTED SPINNING OUT OF CONTROL...SPUN 5-7 TIMES ON THE HIGHWAY AND THEN HIT THE MEDIAN WITH THE RIGHT TAIL END. UPON IMPACT THE STEERING WHEEL ALONG WITH PART OF THE STEERING COLUMN SNAPPED OFF INTO MY LAP WITH NO AIR BAG DEPLOYMENT. THE STEERING WHEEL WAS IN PULLED RIGHT OUT AND WAS NOW IN MY LAP. THE CAR IS NOW IN REPAIR AND I HAVE REQUESTED THE PARTS TO BE SAVED, THE STEERING WHEEL IS GOING TO BE REPLACED. I HAVE CONTACTED PONTIAC AND WE HAD A DISCUSSION...BUT I DON'T THINK THEY UNDERSTAND WHAT HAPPENED I HAVE NOT HEARD A WORD FROM THEM SINCE THE DISCUSSION. *TR
