Open the full vehicle complaint log (all categories)IN FILLING THE GAS TANK WHEN THE PUMP SHUT OFF GASOLINE POURED OUT OF THE GAS TANK. THE FIRST TIME I BLAMED THE GAS STATION. IT HAPPENED AGAIN WHEN MY DAUGHTER WAS FILLING THE TANK. EVEN AFTER THE FUEL NOZZLE WAS TAKEN OUT OF THE TANK, A GREAT DEAL OF GASOLINE POURED OUT OF THE TANK. THE DEALER CHECKED THE CAR OUT AND SAID EVERYTHING WAS ALL RIGHT. ITS NOT!
DT*: THE CONTACT STATED WHEN PUMPING FUEL INTO THE FUEL TANK, THE FUEL BLEW BACK OUT OF THE GAS TANK, AFTER THE AUTO SHUT OFF VALVE ON THE PUMP HANDLE STOPPED. THE SALES/SERVICE DEALER WAS UNABLE TO FIX THE PROBLEM AFTER SIX ATTEMPTS AND WHEN THE MANUFACTURER WAS NOTIFIED, AN OFFER TO BUY BACK THE VEHICLE WAS MADE.
I HAVE A 2006 KIA OPTIMA THAT WAS JUST PURCHASED 2 MONTHS AGO. IT HAS A PROBLEM STALLING WHEN COMING TO A STOP. I HAVE HAD IT LOOKED AT BY THE DEALER SEVERAL TIMES AND THE COULD NOT DUPLICATE THE PROBLEM. I ALSO WORK AT THE SAME DEALERSHIP. ONE OF THE LAST TIMES THIS HAPPENED I ALMOST HIT A BUSINESS SIGN TURNING A CORNER. I BELIEVE THE DEALER AND KIA ARE NOT DOING ALL THEY SHOULD SINCE I WORK THERE. THEY ONLY LOOKED AT THE VEHICLE ONE TIME AND ONLY CHECKED A COUPLE OF THINGS. I HAVE BEEN IN THE CAR BUSINESS ALMOST 20 YEARS AND I AM NOT SATISFIED WITH WHAT THEY HAVE DONE. THE FACTORY REP. FOR KIA DID NOT REALLY CARE. HIS NAME IS [XXX]. I DO NOT FEEL SAFE DRIVING THIS CAR. BEFORE I PURCHASED VEHICLE THE DEALER HAD ALREADY HAD TO REPAIR THE FUEL PUMP ON THE VEHICLE. *NM INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6). *TR
