WHILE DRIVING MY 2003 KIA SORENTO ON AUGUST 14, 2007, THE ENGINE BEGAN TO MAKE NOISES, LOOSE POWER AND SLOW DOWN RAPIDLY. TWO BELTS POPPED COMPLETELY OFF AND THE CAR LOST ALL ITS POWER AND SHUT DOWN COMPLETELY. I TOWED THE CAR TO THE KIA DEALER AT ARBOR PLACE IN DOUGLASVILLE, GEORGIA FOR REPAIRS. THE DEALER INFORMED ME THAT THE CRANKSHAFT BOLT WAS BROKEN AND DID DAMAGE THE CRANKSHAFT PULLEY AND SPROCKET. THE DEALER MADE THE REPAIRS BUT AFTER DRIVING THE CAR A FEW DAYS LATER ON AUGUST 22, 2007 IT BEGAN LOOSING POWER AGAIN. I TURNED OFF THE VEHICLE FOR APPROXIMATELY 10 MINUTES AND TRIED TO START IT UP AGAIN BUT IT WOULD NOT START AT ALL. I AGAIN TOWED IT TO THE KIA DEALERSHIP AT ARBOR PLACE. IN SHORT, THEY SAID THAT THE CAR WAS DUMPING GASOLINE INTO THE CYLINDERS AND THAT WHEN THEY TEST DROVE IT, THE CAR LOOSES GASOLINE RAPIDLY. THE CAR CLEARLY HAS MAJOR MANUFACTURER DEFECTS THAT SHOULD BE FIXED BY KIA AT NO COST TO ME. *TR

LIKE MANY 2003 KIA SORENTO OWNERS THE OVERFLOW TANK IN MINE DEVELOPED A CRACK IN THE BOTTOM THAT IS ONLY VISIBLE WHEN IT IS PRESSURIZED. ALTHOUGH KIA KNOWS THERE IS A PROBLEM WITH THE OVERFLOW TANK IN MOST IF NOT ALL 2003 KIA SORENTO'S AND HAS SENT OUT A TSB TO THEIR MECHANICS OVER HOW TO REPLACE IT. AS SOON AS MY CAR HAD OVERHEATED DUE TO THE LEAK, I HAD TO PAY AROUND $100 TO BUY A NEW TANK FROM THE NEAREST DEALERSHIP BUT ALAS AFTER OVER HEATING MY CAR DEVELOPED MORE PROBLEMS AND ENGINE HAVING TO BE THROWN OUT. THIS HAS COST ME OVER $4300 IN REPAIRS SO FAR, AND HAVE NOT BEEN ABLE TO DRIVE THE CAR I AM STILL MAKING MONTHLY PAYMENTS ON IN NINE MONTHS. NONE OF WHICH ARE COVERED TO THE WARRANTY DUE TO THEIR "10 YEAR 100,000 MILE" POWERTRAIN WARRANTY NOT BEING TRANSFERABLE TO THOSE WHO BUY THE CAR USED. *TR

MY VEHICLE STARTED ACTING UP WHENEVER I TURNED ON THE AIR CONDITION I WOULD LOSE POWER. THE ENGINE LIGHT WOULD COME ON AND THE STEERING WHEEL WOULD GET REAL TIGHT AND I WOULD NOT BE ABLE TO TURN IT. THE VEHICLE IS CURRENTLY AT A KIA DEALERSHIP WHERE IT HAS BEEN FOR 3 WEEKS NOW WAITING ON PARTS. NOT TO MENTION I CALLED KIA ROADSIDE ASSISTANCE FOR 4 DAYS STRAIGHT BEFORE A TOW COMPANY FINALLY CAME AND TOWED MY CAR TO THE DEALERSHIP. I WAS TOLD I NEEDED A CRANK SHAFT, TIMING BELT, AND A ENGINE WHICH IS ALL COVERED UNDER WARRANTY, BUT THEY HAVE NOT RECEIVED ANY OF THE PARTS NEEDED FOR MY CAR. I AM STILL WITHOUT A VEHICLE KIA SAYS THEY DO NOT DO LOANER CARS OR RENTALS SO I AM JUST FRUSTRATED WITH THE WHOLE ORDEAL. *JB

TL*THE CONTACT OWNS A 2003 KIA SORENTO. THE CONTACT RECEIVED A RECALL NOTICE IN JULY OF 2007 REGARDING THE CRANK SHAFT BOAT. HE TOOK HIS VEHICLE TO THE DEALER AND THEY STATED THAT THE PARTS FOR THE REPAIR WERE UNAVAILABLE. WHILE DRIVING 25 MPH, THE CHECK ENGINE LIGHT ILLUMINATED ON THE INSTRUMENT CONTROL PANEL AND THE ENGINE FAILED SIMULTANEOUSLY. HE TOOK HIS VEHICLE TO THE LOCAL KIA DEALER AND THEY STATED THAT THE TIMING BELT CAUSED THE FAILURE. AN INSPECTOR FROM CARFAX STATED THAT THE ENGINE FAILED BECAUSE OF THE CRANK BOAT SHAFT. THE MANUFACTURER REFUSED TO REPAIR THE VEHICLE WITHOUT A SERVICE CHARGE. THE RECALL NUMBER WAS UNKNOWN. THE CURRENT AND FAILURE MILEAGES WERE 67,000.

COOLANT SPILLING FROM THE RESERVOIR (WHICH WAS REPLACED IN DECEMBER 2006, THE PART WAS ON NATIONAL BACK ORDER. I WAITED 5 WEEKS FOR THE PART TO ARRIVE). THE CAR STALLED SEVERAL TIMES AND STEAM CAME FROM THE RIGHT SIDE OF THE HOOD. TODAY IS 8/31/07, SIMILAR INCIDENT HAPPENED WITH THE CAR. THE DEALER SAID THAT THE HOSE FROM THE COOLANT RESERVOIR WAS CRACKED. I ASKED SINCE THE PART WAS RELATED TO THE RESERVOIR WHY DID I HAVE TO PAY ADDITIONAL FOR THE HOSE REPAIR ($193.30). THE DEALER SAID THE HOSE WAS A SEPARATE PART. I DON'T UNDERSTAND WHY KIA DOESN'T RECALL THE RESERVOIR AND ANY ASSOCIATED PARTS. *TR

ON JULY 20, 2007 DRIVING HOME FROM WORK IN THE RAIN, ON THE HIGHWAY MY CAR MADE A LOUD NOISE AND I LOST STEERING AND DID EVERYTHING I COULD TO NOT HIT CARS BESIDE OF ME AND THE POOR GUY BEHIND ME FROM CRASHING IN TO ME. CALLED MY HUSBAND WHO CAME AND PICKED UP THE HARMONIC BALANCE OFF THE HIGHWAY, LIFTED THE HOOD TO FIND A LARGE BOLT (NOW I KNOW CRANKSHAFT BOLT) BROKEN. WHICH I HAVE. I SEARCHED AND FOUND WHERE THERE WERE SEVERAL COMPLAINTS AND THAT KIA WAS GOING TO RECALL. I CALLED KIA ON THE 1ST OF AUG. (CAR HAS BEEN SITTING IN MY DRIVEWAY BECAUSE IT HAS 68000 MILES AND I AM THE SECOND OWNER), WHO HAD MY CAR TOWED TO THE RUSTY WALLACE KIA IN LOUISVILLE, TN. (CHECKED THE MAIL WHEN I CAME HOME AND THERE WAS A RECALL ON CRANKSHAFT BOLTS) IMAGINE THAT. IT IS STILL SITTING THERE AT THE DEALERSHIP. THEY KEEP TELLING ME THE DISTRICT MANAGER IS TRYING TO DECIDE WHETHER OR NOT TO FIX IT. I HAD SPOKEN TO A COUPLE OF TECH'S. AND THEY TOLD ME MY MOTOR WAS GONE. THE BOLT BROKE OFF INSIDE THE MOTOR. KIA IS NOW JERKING ME AROUND. I HAVE HAD TO PUT OFF VACATION AND MY HUSBAND AND I ARE SHARING A VEHICLE WHICH IS COSTING ME A FORTUNE IN GAS BECAUSE WE WORK IN OPPOSITE DIRECTIONS AND I WORK ABOUT 30 MILES FROM MY HOME. CAN NOT GET ANY HELP. I HAVE RESEARCHED AND FOUND HUGE COMPLAINTS ABOUT THIS. KIA HAS KNOWN ABOUT THIS. *JB

I WAS DROPPING OFF SOMEONE AT WORK WHEN THE CAR MADE A THUMP AND ALL THE DASH WARNING LIGHTS CAME ON. I DROVE IT HOME ABOUT TWO MILES AWAY, AND TOOK IT TO A AUTOMOBILE SERVICE CENTER THE NEXT DAY. THEY TOLD ME THAT THE CRANKSHAFT PULLEY WAS READY TO FALL OFF. THE NEXT DAY I HAD IT TOWED FROM THE SERVICE CENTER TO THE DEALER. THE DEALER SAID THE SAME THING AS THE SERVICE CENTER, AND THAT IT WAS UNDER WARRANTY. ALSO, IT A NEEDED A 60000 MILE SERVICE FOR WHICH I PAID EXTRA. WHEN I WENT TO PICK THE CAR 5 DAYS LATER THE CAR WAS MAKING A BELT NOISE, IT WAS SLOW IN STARTING, THE DASH LIGHT WOULDN'T COME ON, AND THE AIRBAG LIGHT WAS ON. WHEN I TOOK IT BACK TO THE DEALER, THEY TIGHTENED THE BELTS AND CHECKED THE OTHER PROBLEMS AT A COST OF $150, AND THAT THESE OTHER PROBLEMS WERE NOT UNDER WARRANTY, AND WOULD COST $1400 TO FIX THEM. I HAVE NEVER HAD A PROBLEM WITH THIS CAR UNTIL THE CRANKSHAFT PULLEY FAILED, AND COULD NOT SEE WHY IF A WARRANTY FAILURE CAUSED SOMETHING ELSE TO FAIL, WHY WASN'T IT FIXED UNDER WARRANTY? ALSO, THE PERSON WHO WORKED ON THE CA RCOMPLAINED ABOUT THE OIL PAN WITH THE SEALER THAT WAS USED TO SEAL THE ENGINE.*AK

Complaints allege that while refueling the vehicle, fuel can spill out or spit back from the fuel filler port on model year (MY) 2003 Kia Sorento vehicles (subject vehicles).Consumers report that the spilled fuel can splash on the person fueling the vehicle, or on the side of the vehicle and the ground.The subject vehicles are equipped with an evaporative emissions control system that, among other things, manages air exchange between the fuel tank and the atmosphere in an environmentally safe manner.The system consists of a vapor canister, various control valves and tubing, and a canister filter (fuel tank air filter) through which the air that flows in and out of the fuel tank must pass.Kia's testing found that if the canister filter becomes significantly clogged, excess pressure can build up in the fuel tank and cause fuel to spit back from the filler port during refueling.Kia has stated that the canister filter requires regularly scheduled service maintenance; however, the component is not listed as a maintenance item in the owner's or service manual for the subject vehicles.ODI notes that Kia does list the filter on the maintenance schedule in the owner's manual for MY 2005 and newer Kia Sorento vehicles.To address the issue of fuel spit back during refueling, Kia will conduct a service campaign of approximately 86,000 MY 2003 and 2004 Kia Sorento vehicles.The campaign will provide a one-time replacement of the canister filter, at no cost to the owner.Kia will begin notifying the affected owners in late January 2012 and will inform the owners that the filter must be serviced at regular intervals.Kia will also provide an updated service maintenance schedule.Consumers should refer to the service campaign bulletin number SC092 available in the investigative file.A safety-related defect trend has not been identified at this time and further use of agency resources does not appear to be warranted.Accordingly, this investigation is closed.The closing of this investigation does not constitute a finding by NHTSA that no safety-related defect exists.The agency will monitor the issue and reserves the right to take future action if warranted by the circumstances.
