I STARTED TO NOTICE AN ODD SMELL IN THE VEHICLE AND NOTICED A LACK OF COOLANT IN THE RESERVOIR TANK. AFTER A FEW WEEKS I REALIZED THERE WAS COOLANT ACCUMULATING ON THE PASSENGER SIDE FLOORWELL. MY VEHICLE IS AT 53,500 MILES AND WAS DIAGNOSED BY THE DEALER AS HAVING A "HEATER CORE FAILURE." THE ESTIMATE THEY GAVE IS $1,300 TO REPAIR. I CANNOT AFFORD IT SO IT LOOKS LIKE MY VEHICLE WILL BE GARAGED UNTIL A RECALL IS ISSUED. *AK
