WHILE DRIVING IN NORMAL RUSH HOUR TRAFFIC MY WIFE HEARD A LOUD POP FROM THE ENGINE COMPARTMENT. THE CAR LOST POWER, BRAKES. SHE STARTED TO COAST TO THE SIDE OF THE ROAD WHEN OTHER COMMUTERS STARTED TO YELL AT HERE TO GET OUT OF THE VEHICLE, AT THAT TIME THE CABIN STARTED TO FILL UP WITH SMOKE. SHE TRIED TO LOWER THE WINDOW BUT THAT HAD LOST POWER ALSO. SHE WAS ABLE TO DRIVE THE CAR INTO THE SNOW AT THE SIDE OF THE ROAD TO STOP IT AND THEN EXITED THE VEHICLE. THE 325XI STARTED TO BURN AND SHORTLY WAS A TOTAL LOSS. THANK GOD SHE GOT OUT OK BUT WAS TRAUMATIZED BY THE INCIDENT. SINCE THIS HAPPENED WE HAVE FOUND MANY SIMILAR FIRES DOCUMENTED ON THE WEB. *TR
