When it is hot and the sun is shining down on the vehicle for a long period of time, the drivers door and rear passenger door locks will not operate from the key fob? when it cools down such as evening or early morning the locks work just fine from the key fob? seems to be related to hot or cool weather. No clue at this point why I have to work the locks manually when it is hot outside?.
Various doors will not properly lock/unlock from the electric switch and the key fob. This is an interment failure affecting multiple doors in the vehicle. Different doors locks are failing at different times, both locking and unlocking. Based on my research on the internet, this affects a significant number of 2005 to 2010 Optima’s. This defect could cause occupants to be trapped in the event of an accident or emergency.
Power door locks will not work at times both inside and with the remote preventing all ability to get out of the vehicle. This occurs when the car is at a stop both while running and not running. I generally do not try to open the doors while I'm driving.
