I was driving the car when I suddenly started hearing rattling noises from the engine. The power steering stopped working and the steering wheel would not turn. Thankfully, I was on a side street with no other traffic. If I had been in traffic or traveling at a higher speed, this would surely have caused a crash. My mechanic says that the crankshaft bolt is sheared off and must be drilled out to be replaced. Kia won't cover this expensive repair, says it is not covered by their warranty. After researching this issue, I see that kia is aware of a defect in the bolt and has issued service bulletins and discontinued the bolt, issuing a new part to replace it. There are already numerous complaints on this and other sites due to this issue, spanning several model years. To date, I have not seen a recall from kia. Dangerous defect and alarming lack of concern (not to mention customer service) from kia. I would never have bought this car if I had known the gamble I was taking with my family's safety. I hope others will not make the same mistake.
