DRIVING S.IN RT LANE AT 60 MPH ON I-26, LSR EXIT, ON OVERPASS, CAR STARTED TO VEER LEFT. WHEN I CORRECTED TO RIGHT, CAR OVERCORRECTED WAY TOO MUCH, TRIED CORRECTING TO LEFT AND CAR OVERCORRECTED WAY TO MUCH AGAIN. IT STARTED GOING RIGHT AND LEFT AND SPUN IN CIRCLES (AS IF IT WERE ON ICE-IT WAS A WARM, SUNNY DAY) AND HIT THE CONCRETE DIVIDER ON THE LEFT..I BEGGED THE INSURANCE ADJUSTER TO LOOK UNDERNEATH BUT THE CAR WAS SO SMASHED DOWN IN FRONT THAT SHE COULDN'T GET UNDERNEATH TO SEE WHAT CAUSED THE FAILURE. I CALLED AND AGAIN REQUESTED HER TO DO THIS WHEN THEY HAD IT ON A LIFT AT THE JUNKYARD, BUT I DOUBT THAT IT WAS DONE. IT WAS DEFINITELY MECHANICAL FAILURE. IT HAD NEW FRONT BRAKES RECENTLY INSTALLED BY THE DEALER AND A DRIVE SHAFT INSTALLED BY CUSTOM BRAKES A FEW WEEKS BEFORE THE ACCIDENT. AN OIL CHANGE AND SERVICE WAS DONE THE WEEK BEFORE. I HAD PRIOR TO THIS NO NOTICE OF IMPENDING FAILURE OF ANY KIND. FROM THE LOOKS OF THE CAR, IT WAS AMAZING THAT I WALKED AWAY. I HAVE PHOTOS. *TR
