Example complaints

Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.

“Doors (all) will lock after unlocking when you're trying to get in. I unlock the door, either manually or with the key fob, when you pull the handle to open the door the doors lock. You can play with it and finally get in but I've heard alot of problems with the same thing on the same model.”

NHTSA complaint #10680712, filed 2015-02, 93,400 miles

“I parked my car for the day to go to work. At that point in time there were no issues with the car. Upon returning that night I found that the driver's side door would no longer unlock. I must now enter and exit my vehicle through the passenger door. The door will not unlock with a key, the unlock-all button, remote entry, interior unlock button, or by turning the car off.”

NHTSA complaint #10510692, filed 2013-05, 75,000 miles

“Power door locks instantly lock after unlocking continuously, prohibiting entry or exit to the vehicle. This poses a safety hazard if there were to be an accident locking me and my children inside the vehicle. Sometimes it takes 5-10 minutes to get in or out of the car trying to catch the door handle at just the right time to be able to open it.”

NHTSA complaint #10410184, filed 2011-07, 90,000 miles

“Door lock for the drivers side does not work and also does not unlock. This presents a huge safety concern, driver cannot exit the drivers' door! We have been able to unlock the drivers' door but it will not open! I reviewed the issue online and found hundreds of the same complaint. Kia needs to address the drivers door issue asap as it is a huge liability since it is an extremely common problem.”

NHTSA complaint #10505583, filed 2013-04, 109,000 miles

“The doors on my Kia Optima (2003) lock by themselves after I unlock the car. When I go to open my driver side door is when the car locks by itself. I am afraid of locking my kids in the car because of this problem. The other day I couldn't get the driver side door open at all.”
