After parking vehicle, went to exit and could not remove ignition key. Key turned off vehicle but would only go as far accs, which means while motor was not running, power was still on. Made sure dash indicator was in park, yet could not remove key. Spoke to a locksmith and added lube to around ignition key without any results. Left inside semi-heated garage overnight in case of frozen components without results. While dash indicator seemed to show proper gear selections, while in park, key could not removed, steering wheel would not lock, and vehicle could be moved forward and backward by manual pushing, in the meantime it was using up the battery. Kia dealership determined "shifter assembly failure", and after $600+ and 6 days for the special ordered part, vehicle was returned, but the failed part was returned to the supplier for a core charge. So if vehicle was parked in a parking lot and ignition key cannot be removed the car could be stolen, if parked on an incline car could roll away because it's truly not in park, and or your battery is dead. There was prior warning of any failure and owned since new.
