A owner told me before that its really hard to source parts for old KIA cars. Also it is really hard to change parts. Sometimes have to dismantle entire engine to change anything. So if the formen is not experienced, during reassembling, he might miss something and you will end up with another problem. But I'm not sure for 2010 model. Best would be, if you know any formen or workshop owner, pay a visit and ask about frequent wear and tear and the repair cost.
