KIA IS RECALLING CERTAIN MODEL YEAR 2006-2008 OPTIMA VEHICLES MANUFACTURED FROM SEPTEMBER 29, 2005, THROUGH JUNE 13, 2007. THERE IS A POSSIBILITY THAT THE SHIFT CABLE MAY HAVE BEEN INSTALLED INCORRECTLY, CAUSING TENSION IN THE CABLE. IF PRESENT, THIS CONDITION COULD CAUSE THE CABLE TO DETACH FROM THE SHIFTER ASSEMBLY'S DOWEL PIN PREVENTING THE TRANSMISSION FROM BEING SHIFTED. THE SHIFT LEVER CAN THEN BE MOVED INTO THE PARK (P) POSITION WHILE THE VEHICLE'S TRANSMISSION IS STILL IN THE LAST USED GEAR BEFORE DETACHMENT.
