Consumer Description

The fuel tank expanded causing the vehicle to become immobile. The car is sitting at a dealership after I declined to sign Kia's buyback so yes it available for inspection. As for my safety and other the fact a fuel tank is swelling under where people would sit and it is highly flammable/ combustible is kind of alarming to me. Yes, there are plenty of people having the same problems. The dealership has sent pictures and videos into Kia for their engineers to look over. The day before the car became immobile it was getting horrible gas mileage. There was no other things that happened no lights on the dash.
