I was merging onto a highway when all of a sudden I heard a loud thud and my battery light & e brake light came on and I lost power steering. I was able to drive the vehicle to a local mechanic who informed me that the harmonic balancer had fallen off due to the crankshaft bolt sheering off. Once it was fixed by an ase certified mechanic, approximately 8000 miles later I was driving to work and the car started shaking like I was driving on rumble strips. I took it back to a service garage and after replacing the harmonic balancer and crankbolt again they came to the conclusion that the crankshaft was bent. The garage suggested replacing the entire crankshaft and balancer and then having the engine rebalanced or a complete engine replacement both of which are greater than $3500 to repair on a vehicle that's worth about $5500. . It's been approximately $2000 that I've already spent to correct this problem and the problem still exists. It's at a local kia dealership now, where I purchased the vehicle and they told me that it's not fixable and they can only recommend to replace the engine which would cost $6,700 for a used engine with 71,000 miles on it. It seems that this same issue happens on these motors between 60k and 90k miles then from doing some research, it seems after repairs are done the same problem happens approximately 6k-10k miles later. After looking into it, it leads me to believe that the only cause of this problem would be manufacturer defects and faulty parts. This has caused me to be out of a vehicle since mid November of 2012. It's disturbing with how many other complaints I'm reading on this site about the same exact thing!.
