Had some noise coming from the front of the car, had my mechanic look at it, he said we needed a control arm. When he took off the cover to replace the control arm, he found the sub frame had rotten and was cracking. As I looked online, I saw that KIA had a recall for this issue. When I contacted KIA, their response was "as my car is not under warranty, they are not required to repair the car" The car in question has 70, 558 miles on it. We are the 2nd owner.

Door lock/unlock mechanism has failed. Unable to unlock and open door from outside or inside. This defect causes the door to stay locked and unable to open. This can trap people inside of the car if they are unable to crawl out a window or exit from another door. There are many reports of this on Kia forums and general Google search. There was no warning that this part was wearing out until it became impossible to open the door.

DRIVER DOOR DOES NOT OPEN FROM INSIDE NOR FROM OUTSIDE. WHEN UNLOCKING THE DOORS, ALL DOORS WILL OPEN EXCEPT THE DRIVER'S DOOR. CENTER LOCK MECHANISM OR MANUAL USE OF KEYS DOES NOT HELP. THIS IS WITHOUT A DOUBT A SAFETY PROBLEM WHERE DRIVER CAN BE TRAPPED IN THE CAR IN CASE OF EMERGENCY. THIS IS VERY COMMON IN KIA OPTIMA MODELS.

DRIVER'S DOOR LOCKING SYSTEM WILL NOT UNLOCK, ALL OTHERS DO. THE DOOR LOCKS ITSELF IMMEDIATELY AS YOU TRY TO UNLOCK EITHER WITH THE KEY (OUTSIDE) OR PRESSING THE CENTRAL LOCK BUTTON (WHEN INSIDE). THIS WOULD BE A SERIOUS PROBLEM IF THE CAR WAS INVOLVED IN AN ACCIDENT AND/OR FIRE WAS AN ISSUE. RIGHT NOW IT IS INCONVENIENT TO CLIMB OVER THE CENTER CONSOLE. I SEE THIS IS NOT THE FIRST COMPLAINT ON THIS SUBJECT AND THE PROBLEM SEEMS ENDEMIC TO THIS CAR. THE PROBLEM STARTED INTERMITTENTLY FROM SEPTEMBER 2016 AND NOW IS PERMANENT AS OF NOVEMBER 30.

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...

ON SEVERAL OCCASIONS, WHEN MANUALLY UNLOCKING THE POWER DOOR LOCKS, THEY WILL IMMEDIATELY LOCK AGAIN AND WILL GO INTO A LOOP OF UNLOCK-RELOCK, WHETHER USING THE MANUAL DOOR LOCK OR THE POWER LOCK SWITCH (THE RELAY CLICKS BUT NOTHING HAPPENS WHEN USING THE SWITCH). THIS HAPPENS ABOUT 10% OF THE TIME.

DRIVERS DOOR LOCK WILL NOT OPEN FROM INSIDE AT ALL & ONLY 10%OF THE TIME FROM OUTSIDE WITH KEY. PULLED FUSE ON ACTUATORS & LOCK CONTINUES TO MALFUNCTION. CAN NOT EFFICIENTLY GET IN OR OUT OF THE CAR. HAVE TO SLIDE OVER CENTER TO REACH PASSENGER DOOR TO GET OUT. I AM 6'4" SO THIS IS A REAL SAFETY HAZARD.

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.
