NHTSA Defect Investigations for the 2006 Kia Optima

The Office of Defects Investigations (ODI) is an office within the NHTSA which investigates serious safety problems in the design, construction or performance of vehicles. The NHTSA is authorized to order manufacturers to recall and repair vehicles, if the ODI finds a safety issue. NHTSA investigations for the 2006 Kia Optima, both ongoing and closed, are listed below:

  1. INVESTIGATION: Transmission Shift Cable Detachment

    NHTSA Preliminary Evaluation #PE10046

    Component(s): Power Train:Automatic Transmission
    Power Train:Automatic Transmission:Gear Position Indication (Prndl)
    Power Train:Automatic Transmission:Lever And Linkage:Floor Shift

    Summary: During manufacture the automatic transmission shift cables in certain subject vehicles were installed incorrectly causing extra tension on the cable.This condition can cause the shift cable to detach from the gear shifter assembly's dowel pin preventing the transmission from being shifted.The shift lever can be moved into the Park (P) position while the vehicle transmission is still in the last used gear before detachment.If this were to occur, and if the driver leaves the vehicle without engaging the parking brake, the vehicle may inadvertently roll away thus creating the risk of a crash.Kia is conducting a safety recall (11V-153) to correct the subject problem in approximately 70,115 model year (MY) 2006 through 2008 Kia Optima vehicles produced from 9/29/2005 to 6/13/2007.Kia has stated that the early MY 2006 Optima vehicles built before 9/29/2005 had different automatic transmission shift cables and shift levers than the subsequent MY 2006 through early MY 2008 Optima vehicles built up to 6/13/2007.Beginning 6/14/2007, Kia changed the assembly process for the shift cables to ensure correct installation.As for the recall remedy, Kia dealers will inspect the shift cables for correct installation, and re-install them, if necessary.For more details on the recall, see NHTSA recall 11V-153.This investigation is closed.
