2006 Kia Optima Owner Comments

problem #4

Once the doors are locked, they can not be unlocked from the inside. The key must be inserted into the drivers side lock cylinder (outside) and manipulated for several minutes back and forth while at the same time pulling on the handle until the right combination of force and timing allow the door to be opened.

Optima 4-cyl

  • 60,000 miles
It is a well-known issue with Kia Optima cars that the door latch is faulty, and after various lengths of time, it will stop unlocking. By no longer unlocking, I mean under any condition. Using a remote, using the key, even sitting in the vehicle pressing the button on the door or manually moving the indicator by the handle. This is a severe safety issue. In the event of a wreck or other emergency situation, it is impossible to exit the driver's side door on my Kia Optima. No matter what you attempt, the door will not open. When you unlock it using any of the aforementioned methods, the car will automatically re-lock the door as soon as you touch the handle, either interior or exterior. While I can understand normal wear and tear eating away at the component, there is absolutely no reason for the car to default to the lock position in the case of such wear and tear. A simple solution would be to have the latch default to the open position, which will allow persons to exit the vehicle in case of emergency. If this has not already cost individuals their life, I am sure it is only a matter of time. This needs to be corrected immediately, before it costs me my family.

Optima 6-cyl

  • 100,000 miles
The drivers side door lock will not unlock with the electrical button or manually. The lock only opens half way - pull handle to open - door automatically locks. Can't open door with key from outside. Must enter in passenger side door and climb over. Big danger as driving with children in the car.
