So the crankshaft bolt on my 03 KIA Sorento LX, has broken/sheared off in the engine. I bought it used and have only had it a month, it's not even paid for yet. I see a lot of people with the same problem on many years and have even seen a few class action law suits out there, has anyone had the same problem? My mechanic is trying to back out the screw, has anyone encountered this problem, replacing the option isn't an option at this time. Any info you can give would be greatly appreciated.
