“Locked car after buying it used drivers door will not unlock. Multiple complaints online about this problem. My daughter was going to drive this thing. Kia dealer did not even mention this to me, but did say it was 200 minimum. I hope this gets investigated. In an accident the door will never open. I drove the car home and after 2 hours it will not unlock.”

“My passenger side door will not unlock, and can not be opened from inside or outside of the vehicle. The only way to exit the vehicle is to either crawl out of the window or crawl over the center console. My fear is if in the event of emergency the door would not open and we would be sick in the vehicle.”

NHTSA complaint #10618806, filed 2014-08, 111,000 miles

“The driver side door will not unlock from the inside or outside. I can hear the assembly trying to work, the key will unlock the other doors. This is a huge safety issue in an emergency. I called the Kia dealership iand they told me they had never heard of this with this vehicle. How many people are going to possibly lose their life in an accident,because of this defect before there is a recall.”
