The car uses way too much oil to only have 40k miles on the motor with no leakage at all. It smokes white cloudy smoke, my check engine light came on, and it also makes a ticking noise constantly. Took it to the kia dealership multiple times. And they can't find anything wrong.
I bought my car 6 months ago, I have performed all required maintenance for the vehicle and at 17,000 miles there was a ticking sound while I was driving on a busy road with my handicapped mother. There was a loud noise and I thought I blew a tire, the engine seized up and I was in the middle of the road, I had to call emergency road service to get my mother and I safely home. After getting the vehicle towed to the kia dealership I am told the engine is needing to be replaced because a rod was thrown threw the motor. We were very lucky that neither one of us was injured with this incident however others may not be so lucky.
