So I've noticed that when I am trying to lock the doors from the inside lock button on both the driver and passenger side only the rear left passenger door is able to lock, I hear the locking sound though, then when I unlock the door on the front passenger side from the outside all doors are able to unlock. I know that is part of the function of the car. Is there a problem with the door lock actuators or could it be something else?
