On the inside trim, you can remove screws that are by the door handle, arm rest, under door and side of door and then gently pull back on the panel as there will also be retaining clips attached and you don't want to break them. You'll need to lift the door panel upwards in order to get it off the window ledge. Then you'll need to manipulate the panel and disconnect the door handle linkage from the door handle and disconnect the wiring for your controls. Then you can access the bolts that secure the mirror onto the door

Hi, This could be a turbo related problem, or at worst a broken piston or oil ring! check the turbo out 1st, as if your talking about a ring everything & engine stripped down. Please send me feedback to [email protected] Thanks Malcolm Campbell.

pull off the door panel an check to see if the striker rod is connected. it is a thin long steel bar...if the handle is broken remove the door panel an replace the handle

The rod connecting the outside latch handle to the latch catch is disconnected. Someone will need to take the door panel off and repair the connection rod. It was a broken plastic connector that joined the rods on my 2003 Kia Optima that caused the problem.

FIRST: If it is under warranty, take it to the dealer!
If not, from your rather limited description it sounds as though the attachment rod that operates the latch mechanism is either so loose or disengaged that it will not rotate the security latch to "unlock" your door. Open up the attachment point and the panel to determine what exactly has loosened or failed and replace the hardware and then properly secure eveything.

i would first try the local junkyards in your area if not jusdt try shopping online for the part www.kiacarparts.net is one source

This happened to me, I removed the interior light fixture on the rear hatch and reached in to pull the connecting rod, this works for an one off opening, you will need to take the panel off once the hatch is open and repair your outer handle, our connection was broken at the handle which I repaired and it works great. Hope this helps.

sorry, i am not sure what happened there!
