Passenger and driver door locks will not unlock 85% of the time, preventing normal entry to / exit from the vehicle. Multiple attempts using the key in the door latch are required to gain entry the other 15% of the time. This is a huge safety issue in case of crash, fire, or carjacking. Internet research shows this to be a common issue around 100K miles. This should be a recall event...

Driver door would not open from inside or out. Power door lock would automatically re-lock all doors when attempting to open or unlock with key or inside lock lever. Had to crawl over console to get in or out when finally able to get passenger front door to open. Finally able to get door open by holding key cylinder in unlock position and forcing handle to open. Unhooked door lock actuator. As long as locked or unlocked door with key only, door would open. If locked door with inside lock lever, door would not open again. Mechanic replacing the driver front door latch assembly repaired vehicle. Very dangerous situation if in accident or vehicle fire.

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.

Sub frame rot leading to poor handling, tire wear, bad engine performance. The rotted supframe is separating from body, causing poor performance. The car is performing poorly at all speeds. Not safe...

Optima 6-cyl

  • 62,000 miles
I was driving on I-10 westbound, katy tx freeway, travelling about 65 miles per hour. The passenger's side front tire blew out causing the car to go back and fourth between two lanes of traffic. In the process, I was hitting the rubber dividers, damaging the hood of the car and the windshield. The blown tire caused damage to the oil pan, the radiator, and eventually the transmission. I got the car to the emergency lane. The car was towed off the freeway and eventually picked up and transported to a car repair shop. A few days later, the insurance adjuster and the repair shop owner both agreed the car was a total loss. I had to buy a new car.

Driver's door locks and cannot be opened with a key and does not open once inside of the car. The operator essentially is locked in the car. In the event of a crash or fire, the occupant may not be able to easily vacate the vehicle; the only way would be to climb over the console to the passenger compartment or the rear to exit the passenger doors. There have been numerous complaints with no action taken by the manufacturer to remedy the defect and affects multiple manufacturing years. In my opinion it clearly is a safety issue.

The passenger wheel came off the car as my son was backing out of a parking space at a grocery store. I bought this car new. That part of the car had never been worked on. The car had to be towed to a garage for repair. Kia used glue on life a support nut on a ball joint, where they should have used a cotter pin. I have bought four (4) Kia. These cars are still in the family. The Kia I drive daily is identical (except being automatic) to the one that the wheel came off.

problem #8

  • 110,000 miles
The drivers door will not open either from the inside or the outside. The door remains locked as the button and key do not fully unlock it. Using both button and key at the same time, I was able to unlock the door and open it. Dissassembly of the door and latch located the problem to be the door latch mechanism. The door latch is designed to fail as evidenced by the number of complaints listing this part. The lever that is moved into place when the door is unlocked is blocked by the cam that it interfaces with because the cam has rotated beyond the point that it should. This has the potential to trap someone in the car if it should fail at the wrong time.

Driver door refused to open. I have a disability so this created a huge problem for me. When I put gas in my car (regardless of grade or gas station) my car refuses to start. When I make a U-turn, my car makes loud clicking sound. I had it checked...my axle and every thing else looks fine. No one can establish where the noise comes from. My car has less than 60,000 miles on it, and it should not have all these issues but it does.
