I even got into a rear-end accident 1 1/2 years ago that I could have avoided with competent brakes. I now have to replace the drums and rear shoes because they have been working overtime to compensate for the poor front brakes. Thanks a bunch Kia! Worst car I've ever driven.

I was then deployed to iraq. I left the car with a good friend. When I came back he informed me that the car wouldn't start. Dealer said it was the fuel pump. Friend replaced the fuel pump.friend then replaced fuel pump again when car wouldn't start. Friend left the car alone,when it didn't start, until I had returned from iraq. I came back and took the car to midas, due to the fact that the dealer didn't have an idea of what was going on. Midas then said it was the fuel pump. I had it replaced for a third time. Car ran for a day then died. I took the car back to midas they said it was the wiring harness. I had that replaced. Car still didn't start. …
