Car wouldn't start when I pushed it to start, the next day it started. On 1/4/2012 driving the car at approximately 30 mph and the car shut off. The car did restart but shut off again while driving. Restarted and had it towed to kia. They had the car until 1/9/12. I was told there was a problem with the fuse block. They replaced ems block control harness. On January 30,2012, the car wouldn't start again. Had it towed to kia. They kept the car and on 2/1/12 and 2/2/12 the car didn't start for them. I was told they moved around the computer and then the car started. I was also told that there was no fuel pressure that time. They replaced pcm. I took it to the kia garage on 4/26/13 for a routine oil change. That day got the car back and had oil leaking all over my driveway. I have had problems ever since. Took the car back 2 times for oil leak. During the time it was in the garage I was told the oxygen sensor needed replaced, after being replaced I was told there was to much voltage going to the sensor and they didn't know why. Currently I am told the cars computer needs to be replaced. We still haven't gotten the car back.
