I LEFT MY HOUSE TO PICKUP MY STEPSON FROM PRACTICE. WHILE DRIVING TO THE SCHOOL I BEGAN TO SMELL AN ODOR OF MELTING PLASTIC, PULLING INTO MY STEPSON'S SCHOOL, I BEGAN TO SMELL AND SEE SMOKE. WHEN I GOT CLOSER TO THE PARKING AREA, SPARKS BEGAN TO FALL FROM UNDERNEATH THE RIGHT PASSENGER DASH. I IMMEDIATELY PARKED THE CAR AND RAN AROUND TO THE RIGHT PASSENGER SIDE AND OPENED THE DOOR. I TOLD THE KIDS TO MOVE BACK AND PLACED A COFFEE CUP UNDERNEATH TO CATCH THE FLAMES DRIPPING FROM UNDER THE DASHBOARD WHICH WAS QUICKLY SPREADING AND BURNING THE CARPET. I TOLD MY STEPSON TO CALL THE FIRE DEPT. I TOOK HIS PHONE AND GOT THROUGH TO COLLIN COUNTY. AND THEY SWITCHED ME TO THE LOCAL FIRE DEPT. BEFORE THE FIRE DEPT ARRIVED, MY CAR WAS ENGULFED IN FLAMES AND A TOTAL LOSS. THE FIRE REPORT CONCURS WHERE THE FIRE BEGAN. I HAVE SEARCHED ONLINE AND FOUND THAT THIS IS A COMMON REOCCURRING PROBLEM WITH HUMMERS AND THERE ARE MANY REPORTS SIMILAR TO MY EXPERIENCE. AS A MATTER OF FACT, I HAVE HAD TO REPLACED THAT SAME HARNESS ABOUT SIX MONTHS AFTER I PURCHASED THE CAR BECAUSE WE SMELLED SMOKE AND REALIZED THE VERY SAME PART HAD BURNED. MANY OTHER HUMMER OWNERS HAVE REPLACED THIS PART MULTIPLE TIMES DO TO THIS DEFECTIVE BLOWER MOTOR FAN HARNESS. THE PROBLEM IS HUMMER KNOWS THE PART IS DEFECTIVE AND THE REPLACEMENT IS ALSO DEFECTIVE. ALSO, THAT PART IS A DEALER ITEM. THIS PROBLEM NEEDS TO FIXED WITH A NATIONAL PUBLIC RECALL BEFORE SOMETHING TERRIBLE OCCURS. WHEN MY CAR CAUGHT ON FIR
