OUT OF NOWHERE MY DAUGHTER'S CAR DOOR WOULD NOT OPEN, TRAPPING HER INSIDE. IT WON'T OPEN WITH THE KEY OR REMOTE. I CALLED KIA AND THEY SAID MY WARRANTY RAN OUT AND THERE IS NO RECALL DESPITE THIS BEING A COMMON ISSUE-- A VERY DANGEROUS SAFETY ISSUE I MUST SAY, SINCE THE DRIVER AND PASSENGERS COULD POSSIBLY BE TRAPPED AND DIE IN AN EMERGENCY.
THE DRIVER SIDE DOOR WILL NOT OPEN FROM THE INSIDE OR OUTSIDE, WITH OR WITHOUT THE KEY. I'VE TRIED EVERYTHING AND CAN'T GET IT TO OPEN. I HAD TO CRAWL TO THE PASSENGER SIDE AFTER GETTING HOME TO GET OUT.
