Latches/locks/linkages

53 reports
“MY MAIN ISSUE IS THE DOOR LOCK ON THE DRIVERS SIDE. I CAN NOT OPEN MY DRIVERS SIDE DOOR FROM INSIDE OR OUTSIDE THE VEHICLE. THIS IS A MAJOR ISSUE AND THE PROBLEM HAS BEEN ALL OVER THE INTERNET FOR YEARS. EVERYONE THAT I KNOW THAT HAS A 2003 AND 2004 KIA OPTIMA HAS THE SAME PROBLEM. I BET EVERY VEHICLE KIA SOLD FOR THESE YEARS HAS THIS PROBLEM. MY OTHER ISSUE IS I AM UNABLE TO FILL MY FUEL TANK AS I NORMALLY COULD DO. I HAVE TO TRICKLE THE FUEL IN THE TANK BECAUSE IF I PUMP IT TOO FAST THE PUMP WILL CUT OFF. I'VE EVEN HAD THE FUEL SPILL OUT OF THE TANK BEFORE THE TANK WAS EVEN FULL (IT WAS AT ABOUT 3/4 FULL). PLEASE DEMAND THAT KIA RECALL THESE PROBLEMS. I CAN'T BELIEVE IT'S TAKING THIS LONG FOR THIS RECALL TO BE ISSUED. I JUST FOUND OUT ABOUT THIS FORM AND THAT IS WHY I HAVE TAKEN SO LONG TO PROCESS THIS FORM. THANKS AND I HOPE THAT YOU CAN HELP ASAP. [XXX] PS. AS OF TODAY MY VEHICLE HAS APPROXIMATELY 53,000 MILES. I'VE DRIVEN IT IN ONE WINTER SO FAR (LAST WINTER) AND IT STARTED HAVING THE DOOR LOCK PROBLEM AT AROUND 33,000. THE FUEL ISSUE STARTED AROUND 2 YEARS AGO. *TR”
