2007 KIA RIO Latcheslockslinkages Problems

MY REAR PASSENGER DOOR WILL NOT OPEN, EVEN WITH FORCE. I NOTICED THIS ABOUT A MONTH AGO WHEN I ATTEMPTED TO OPEN IT TO PUT IN PACKAGES. PRIOR TO THAT I DO NOT KNOW HOW LONG THE PROBLEM OF THE STUCK DOOR EXISTED SINCE I AM A SINGLE PERSON AND RARELY USE IT. I BROUGHT IT TO PHIL SMITH KIA, THEY SAID IT NEEDS A COMPONENT FOR THE LOCKING MECHANISM, IT WOULD COST ME AROUND $300. I SAID I WOULD GET IN TOUCH WITH THE NHTSAS(YOU) THEY TOLD ME TO CALL KIA-WHICH I DID, TALKED TO JUSTINE(EXT-45161), SHE SAID THEY WOULD PAY FOR PARTS IF I WOULD PAY FOR LABOR. I FEEL THAT IS NOT GOOD ENOUGH, I NEVER USE THE PASSENGER REAR DOOR, ITS A DEFECT AND THE REST OF THE DOOR LOCKS MIGHT ALSO BECOME DEFECTIVE. THEN I DID A SEARCH AND THIS SEEMS TO BE A COMMON...

LEFT FRONT DRIVER'S DOOR INSIDE LATCH RELEASE HANDLE SUDDENLY FAILED TO RELEASE THE DOOR LATCH, THE DOOR WAS UNLOCKED AT THE TIME. THIS OCCURRED AT 0445 HOURS ON 30 OCT 2009 WITH APPROXIMATELY 62,200 MILES ON THE ODOMETER. A NEW PART HAS BEEN ORDERED FOR REPLACEMENT OF THE BROKEN PART ON THE SAME DAY, THE OLD PART WILL BE AVAILABLE. *TR
