Door latch won't open from inside or out, Kia needs to address this common problem now instead of waiting for a lawsuit.
When inside the car , and door locks are actuated The only way to unlock the door (s) is to roll the window down and use the key from the outside to sufficiently actuate the locking mechanism to beable to open the door.
The Locks all go click... and the little buttons all move in acordance to what once was the unlock proceedure... but in order to get the mechanism to enguage sufficiently , the key must be used while simultaniously pulling the latch handle.
Started on the drivers door only... and now the passangers side is the same way...

Looks like the latch assembly is "frozen". I have taken the inside door cover off and looking at the assembly and the actuator. The door is in the lock position and the lock itself will not allow me to leave the door unlocked. I push on the rods towards the back to unlock the door and the rods do push, but return to the lock position. I am trying to fix myself and will update everyone if they want to know.....

Front door locks unable to unlock manually or useing the switch. Resorted to rolling window down hitting the switch toggle back and forth while pulling external door handle. I would think this is a safety hazard if in an accident.

Door locks feeze up and it is extremely difficult to unlock the driver's door.
The only door that works properly is the drivers door. The back doors unlock sometimes. The front passenger door can unlock, but when I pull the handle it relocks. Sometimes I'll unlock all of the doors and try to open a door and they all relock. This is so dangerous. I can't have any passengers as they might get locked in. I hurt my rotator cuff trying to load the passenger side from the drivers side. This should be covered by Kia immediately.

Drivers door wont open. When I pulled the interior door handle to exit the car the handle moved but the door would not open. The passenger and rear doors worked. The drivers door would not open with the key either. You can hear the power door locks activate but the door will not open. After 15 minutes of trying different ways of pressing the power unlock on the remote the latch finally released. The door is open but after closing it again it failed to open. Took it to the dealer who replaced the latch at a cost of $255, cost to buy the latch at the dealer was $78 if I could do the repair myself.

Door locks freeze up and you have to lock and unlock the door several times for it to disengage and open up.
