What owners report

  • Airbags failed to deploy during crashes, sometimes after the airbag warning light had already illuminated on prior dealer visits.
  • Electrical wiring issues led to smoke and, in one case, a fire under the hood.
  • A wiring problem was linked to a car moving out of control in reverse, with hot wires forcing the driver to wait for firefighters.
  • Headlights were reported to be aimed too low to illuminate the road at night, and a dark band blocked part of the windshield view.
  • Front tires showed severe vibration, roaring noise, and tread separation at low mileage.
  • Some owners reported the engine running rough and stalling shortly after starting or while driving.

2006 Kia Optima recalls

2 NHTSA recall campaigns list this model year.

  1. NHTSA 12V014000Jan 17, 2012Airbags145,755 vehicles

    Air bags:frontal

    Kia motors america, inc. (kia) is recalling certain model year 2006-2008 kia optima vehicles manufactured from september 29, 2005, through january 29, 2008, and model year 2007 and 2008 kia rondo vehicles manufactured from september 13, 2006, through march 21, 2008. The clock spring contact assembly for the driver's side air bag supplemental restraint system (SRS) may become damaged through usage over time. If the clock spring contact assembly becomes damaged, the driver's air bag electrical circuit will experience a high resistance condition potentially causing the driver's air bag to not deploy.

    Risk: If the clock spring develops high resistance, in the event of a crash, the drivers air bag will not deploy and will not be able to properly protect the driver, increasing the risk of injuries.

    Remedy: Kia will notify owners, and dealers will replace the vehicle's air bag clock spring contact assembly, free of charge. The safety recall began on july 11, 2012. Owners may contact kia customer assistance center at 1-800-333-4542.

  2. NHTSA 11V153000Mar 9, 2011Transmission & Powertrain70,115 vehicles

    Power train:automatic transmission:lever and linkage:column shift

    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.

    Risk: If the driver leaves the vehicle without engaging the parking brake, there is a possibility that the vehicle can roll injure a person in its path or cause a crash.

    Remedy: Dealers will inspect the shift cable and reinstall if necessary free of charge. The safety recall began on march 23, 2011. Owner may contact kia at 1-800-333-4542.

Why is the 2006 Optima capped at a Good verdict instead of Best?
