25 of the
190 complaints about the 2003 KIA Optima are about the
electrical system — 13% of everything
reported for this model year.
Half of the failures with a mileage on record happened before
78,769 miles.
AFTER 60,000 MILES, WHILE DRIVING OR WITH THE ENGINE RUNNING, THE ENGINE LIGHT CAME ON AND STAYED ON. THIS HAS BEEN REPAIRED THREE TIMES BY REPLACING A MAIN FUSE. EACH TIME IT HAS BEEN REPAIRED, THE PROBLEM HAS REOCCURRED. IN CONNECTION WITH THIS PROBLEM, THE DOOR WILL LOCK AFTER THE DRIVER EXITS THE CAR. SOMETIMES, THE KEYS HAVE BEEN LOCKED IN THE CAR.

FIRST: IN THE AFFECT PARTS SECTION OF THIS COMPLAINT THERE IS NO WHERE TO MARK DEFECTIVE LOCKS. I HAVE 2003 KIA OPTIMA SE FOUR-DOOR. IT WILL CONTINUOUSLY LOCK AND UNLOCK AUTOMATICALLY. WILL ONLY STOP CLICKING ON AND OFF WHEN ENGINE IS TURNED OFF. THIS POSES A SAFETY ISSUE BY BEING LOCKED IN AN AUTO WITH ELECTRONIC LOCKS THAT CANNOT BE UNLOCKED EITHER MANUALLY OR WITH THE KEY FOB. WHEN WILL THERE BE A RECALL, EITHER INVOLUNTARILY OR VOLUNTARILY. I BOUGHT THIS AUTO NEW AND STILL HAVE IT.

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.

POWER DOOR LOCKS RE-LOCK AFTER YOU UNLOCK THEM AND PULL ON THE DOOR HANDLE TO OPEN THE DOOR. THIS CAN EITHER TRAP YOU IN YOUR CAR, OR TRAP YOU OUT. YOU HAVE TO GO AROUND TO THE OTHER SIDE, BUT CRAWLING OVER THE CENTER CONSOLE TO THE DRIVER'S SIDE IS ALMOST IMPOSSIBLE. HAD THE SWITCH AND ACTUATOR REPLACED ON THE DRIVER'S SIDE. ABOUT A YEAR LATER, THE SAME THING HAPPENED WITH THE PASSENGER SIDE DOOR. KIA DOESN'T SEEM TO CARE SINCE IT GETS THEM OVER $300 WORTH OF BUSINESS EACH TIME.
