I WAS DRIVING MY '02 CHEVY TRAILBLAZER ON THE INTERSTATE. THE VEHICLE SLIPPED AND FISHTAILED A BIT AND I PRESSED THE BRAKES TO BRING THE VEHICLE TO A STOP. WHEN THE VEHICLE CAME TO A STOP, I TRIED TO ACCELERATE FORWARD, BUT IT WOULD NOT MOVE. THE VEHICLE HAD NOT TURNED OFF ON ITS OWN. I MANUALLY SHUT OFF THE ENGINE AND RESTARTED THE VEHICLE AND PROCEEDED TO MOVE ONTO THE SHOULDER OF THE INTERSTATE. I THEN NOTICED SMOKE AND A SMALL FLAME COMING FROM UNDER THE HOOD NEAR THE FRONT PASSENGER TIRE/WHEELHOUSE. THE FLAMES GOT BIGGER AND SOON IT SPREAD TO THE ENTIRE ENGINE. THE FLAMES STARTED NEAR THE RIGHT PASSENGER WHEELHOUSE AND MOVED TO THE LEFT DRIVER WHEELHOUSE. IN ABOUT 20 MINUTES THE ENTIRE VEHICLE WAS ENGULFED IN FLAMES. I HAVE NO IDEA HOW OR WHY A FIRE STARTED. I LOOKED AT FORUMS ONLINE AND MANY VEHICLES LIKE MINE HAVE CAUGHT ON FIRE WHILE DRIVING. *TR
