 Model years 2002-09 contain a defective engine crank sprocket that when the bolt breaks, causes you to loss your power steering and the engine is JUNK.  The bolt broke while I was on the highway doing 65 MPH.  When I went to steer on to the on ramp, I had NO power steering and almost went off the road.  I had the car towed to the dealer and they told me the crank shaft bolt broke and I needed a new engine to the tune of $5000.00  I purchased the car used 6 months before for $8900.00 and there was less than 91,000 miles on it.  I ended up losing my shirt on this piece of junk that Kia KNEW was defective.   They don't seem to care that someone can get killed when this happens.
