FUEL TANK LEAKS DUE TO CORROSION NEAR FILLER TUBE. THIS IS A SIMULAR PROBLEM TO THE FUEL TANK CORROSION EXPERIENCED BY 2006-ON KIA SPORTAGES. DESCRIPTION: FUEL WILL LEAK FROM THE TANK WHEN THE TANK IS FULL DUE TO RUST/CORROSION OF THE TANK NEAR THE FILLER TUBE. THE VEHICLE IS OPERATED/OWNED IN MICHIGAN, AN AREA THAT USES LARGE AMOUNTS OF ROAD SALT DURING THE WINTER MONTHS. FUEL LEAKAGE IS POSING A POTENTIAL FIRE/EXPLOSION RISK AS FUEL VAPORS FROM THE LEAKAGE MAY BE IGNITED. FUEL LEAKAGE OCCURS BOTH WHEN THE VEHICLE IS STATIONARY AND IN MOTION. IF THE VEHICLE IS PARKED IN A CLOSED GARAGE THE VAPORS CAN ACCUMULATE, ELEVATING THE RISK FOR FIRE/EXPLOSION. (SIMULARLY THE REAR COOLANT LINES RUST THROUGH AS WELL DUE TO ROAD SALT, WHICH IS A KNOWN PROBLEM WITH THE KIA SEDONA)
