WE JUST PURCHASED IS CAR LAST SATURDAY AND WENT TO THE STORE AND LOCKED THE DOORS THEN WHEN WE WENT TO UNLOCK THE DOORS WITH THE KEY ON THE DRIVER SIDE THE DRIVER DOOR WOULD NOT UNLOCK. I WOULD TURN THE KEY AND PULL THE HANDLE AND THE DOORS WOULD LOCK BACK. I HAD TO GET IN AND BACK OUT THROUGH THE PASSANGER SIDE. WHEN I GOT HOME MY SON FINALLY GOT IT TO UNLOCK AND OPEN AND EVERYTIME WE WOULD LOCK IT IT WOULD NOT UNLOCK OR OPEN. WE JUST HAVE TO KEEP WORKING WITH IT UNTIL IT FIANLLY UNLOCKS AND THE DOOR OPENS. SO NOW I AM AFRAID TO LOCK IT. I READ ONLINE OF MANY REPORTS OF THIS SAME PROBLEM AND IT WOULD REALLY BE NICE TO GET A RECALL FOR IT. *TT

I EVEN CONTACTED KIA'S COMPLAINT DEP…
