THE SCION XB 2009 WAS DRIVING ON THE HIGHWAY, AT SPEED LIMIT, 10 MILES AFTER THE "NEEDS MAINTENANCE" OIL LIGHT CAME ON. AFTER 15 MINUTES, THE CAR MADE A LOUD BANG NOISE WHICH WE THINK CAME FROM THE ENGINE.AFTER THE BANG, CAR PULLED OVER. ANOTHER CAR PULLED OVER TOO, SINCE A PIECE OF FLAMING DEBRIS FROM MY CAR CAME OUT FROM UNDERNEATH AND BROKE THAT CAR'S WINDSHIELD. THAT DRIVER INDICATED THAT MY SCION WAS ON FIRE AND TO GET OUT OF THE CAR! ~5 SECONDS LATER THE FIRST OF MANY EXPLOSIONS HAPPENED. THE CAR QUICKLY, WITHIN ONE MINUTE, BECAME COMPLETELY ENGULFED IN FLAMES. BY THE TIME THE FIRE DEPARTMENT ARRIVED THE CAR WAS "FULLY ENGAGED" (100% BURNING). IT IS A TOTAL LOSS.
