2004 kia - gas leaking under car when filling gas tank. Kia told us it was a "sensor" and replaced it. It happened again - they replaced the same sensor. When it happened for the third time, we brought the car in and they told us it was a gas overflow problem and by the time they looked at the car, we had over 27 pounds of gas sitting under the back seat. They told us (because so much time had passed, we had to pay which we did to get the car. They also told us they would contact kia and try to get us reimbursed. All to no avail. The first sensor was replace within first year. By the time the finally realized what the "real" problem was - the car was 4 years. They told us warranty had run out. This sounded like we were sitting on a time bomb! they tried to blame us - they say it's the way we pump gas.
