DRIVING DOWN I-85S IN BETWEEN MORELAND AND GRANTVILLE, GA MY CAR MADE A THUMP SOUND AND THEN CUTOFF. I PULL THE CAR TO THE SIDE OF THE INTERSTATE TO SEE WHY IT CUT OFF. I EXITED THE CAR WITH MY PASSENGERS AND WE NOTICED SMOKE FROM THE ENGINE AREA. THE NEXT THING WE NOTICE IS THAT THE CAR CAUGHT FIRE AND WENT UP IN FLAMES.
