“The gas tank on my 1998 Kia Sportage is seriously corroding. My local garage mechanic stated that this is a serious condition as it could start leaking or break loose from the car. As I understand there is a NHTSA investigation (ea06007) currently being conducted. Please include me into the investigation so that this problem can be remedied.”

“Driver and passenger scalded with boiling radiator fluid with foot on pedal, had to keep foot on petal to get off road on may 30, 2013, at approx. 4:30 pm edt, I was driving my 1998 Kia Sportage on the garden state parkway north, just after entering the highway at exit 98 in wall, nj. The air conditioner had not been working well. The local temperature was in the high 90s, near 100 degrees. I had a passenger in the front passenger seat. Suddenly, anti-freeze smoke came out of the dashboard vents, then, hot scalding anti-freeze began falling on my right foot as it was on the accelerator pedal. …”

“Strong odor of gasoline in and around the car indicated a fuel leak. When investigated the leak was found coming from the fuel tank underneath the center part of the vehicle. Appears to be due to corrosion of the tank. We are still checking on replacement fuel tanks for replacement and are not able to drive the vehicle.”

“Dt: the contact stated the check engine light illuminated. A diagnostic test indicated it was the maximum airflow unit. The vehicle hesitated while driving at any speed. The vehicle has not been inspected by a dealer to determine the exact problem with the vehicle. Updated 12/7/2005.”

NHTSA complaint #10141622, filed 2005-12, 80,000 miles

“Engine connectors c144 (throttle position sensor), c129 (mass air flow sensor) and c146 (idle speed actuator) lose circuit continuity with movement of the engine causing engine hesitation, loss of power and false check engine light indication on the instrument panel. Wiggling the appropriate connector restores continuity temporarily but it will recur again shortly within a day or two of operating the vehicle.”
