My fuel tank expanded while I was driving on the highway, causing my car to stall and would not respond to me pushing on the gas. I pulled over on the side of the highway and looked back and saw my rear seats were pushed up. Got it towed to the Kia dealership and they informed me that my car was totaled because the gas tank expanded so much it bent my frame. This has been an ongoing issue with Kia/Hyundai vehicles but they have still not issued a formal recall, only a voluntary callback even though this is a very dangerous defect.

The car has a sudden loss of power but doesn't shut off. The drivers eat doesn't move towards or back and the back seat popped up for no reason whatsoever. We have taken it to the dealership and they say its not a recall but its doing the same things that others in the same year and model are doing. Why isn't this one on the list . Its paid off and haven't been able to drive it for a year now . Wasted money getting it towed to dealership and back . Ridiculous!!!!
