MY 2003 KIA SORENTO STOPPED WITH NO WARNING OR INDICATION OF A PROBLEM AT 67,735 MILES DUE TO WHAT WAS LATER DETERMINED TO BE ENGINE OVERHEATING. AT FIRST THE KIA DEALER SAID IT WAS DUE TO THE COOLANT RESERVOIR CRACKING AND GOING EMPTY. SINCE THIS IS NOT A PART OF THE ENGINE'S ACTUAL MEANS OF COOLING, THEY CHANGED THEIR STORY TO THE THERMOSTAT FAILED. KIA SAID THAT THIS PORTION OF THE WARRANTY PASSED AT 65,000 MILES. THEIR WARRANTY SAYS 100,000 MILES. COST OVER $3,600.00 TO REPAIR, SIMILAR SITUATION AT 80,000 MILES FOR $1,400.00. STILL NO WARRANTY COVERAGE. I HAVE FURNISHED COMPLETE MAINTENANCE RECORDS SHOWING MAINTENANCE AT EVERY INTERVAL REQUIRED BY KIA. LOOKING FOR SOME ONE TO JOIN IN A CLASS ACTION SUIT. *TR

MY 2003 KIA SORENTO KEPT LOSING ANTIFREEZE AND TO FIND OUT THE RESERVOIR HAD A CRACK IN IT. ALSO, AFTER I PURCHASE BRIDGESTONE FIRE DESTINATION TIRES A YEAR LATER THEY WERE WORN AFTER SPENDING $600.00 I HAD TO HAVE TWO OF THEM REPLACED WITHIN A YEAR. P245/70R16. ALSO 2 DEFECTS RECALLS WHEN MY CAR WAS PUT IN THE SHOP ONE FROM 2007 SC073 AND SC072 WHEN MY CHECK ENGINE LIGHT CAME ON. IT WAS STILL ON AFTER THE CAR WAS SUPPOSEDLY FIXED BY QUIRK KIA IN BRAINTREE. WHEN I WAS DRIVING OUT OF THE PARKING LOT THE CHECK ENGINE LIGHT WAS STILL ON. I WAS TOLD THE CAR WAS FINE AND IT WAS JUST A SENSOR AND TO FIX IT THE COST WOULD BE OVER $200. A YEAR LATER, I BROUGHT IT TO GET A STICKER, THEY REJECTED MY FOR ANOTHER RECALL THAT SHOULD HAVE BEEN FIXED WHEN I BROUGHT IT IN LAST YEAR. THE RECALL WAS FROM 2005. NOW I AM TRYING TO CONTACT THE DEALERSHIP BECAUSE OF THE INCONVENIENCE OF ME GOING TO GET THIS FIXED WHEN IT SHOULD HAVE BEEN TAKEN CARE OF LAST YEAR. I WILL NEVER BUY A KIA AGAIN, THE DEALERSHIP DOES NOT CARE ABOUT THEIR CARS OR CUSTOMERS. *TR

HEAD GASKETS WARPED AT 28,000 MILES, OVERHEATED WITHOUT WARNING, NO SPIKE IN TEMP GAUGE, WHAM SMOKE FROM EVERYWHERE AND EVEN WITH PROOF OF MAINTENANCE UPKEEP IT TOOK KIA 2 MONTHS TO DECIDE TO HONOR THE WARRANTY. THIS WAS AFTER THE CHECK ENGINE LIGHT WOULD COME ON EVERY TWO SECONDS AND HAVE TO BE IN THE SHOP FOR MONTHS FOR THEM TO SAY NOTHING WRONG WITH IT, EVEN WHEN IT WAS TOWED IN EVERY TIME BECAUSE IT WOULD JUST SHUT OFF. THEN THE HEADLIGHT ISSUES ARE INSANE. EVERY OTHER MONTH AND THAT IS NO EXAGGERATION I HAVE TO REPLACE EITHER LOW BEAMS, HIGH BEAMS, BRAKE LIGHTS & TAIL LIGHTS. *TR

KIA INFORMED ME OF A "CRANK SHAFT BOLT" RECALL FOR MY 2003 SORENTO LX. 3 DAYS AFTER HAVING THIS REPAIR PERFORMED, MY CAR BEGAN TO JUST "DIE" AT HIGH SPEEDS ON THE FREEWAY, BUT IT WAS INTERMITTENT AND THE KIA DEALERSHIP TOLD ME THEY PROBABLY WOULDN'T BE ABLE TO FIND THE PROBLEM IF THEY COULDN'T RECREATE IT. AN INTERNET SEARCH ON THE ISSUE REVEALS MANY CONSUMERS HAVING THIS SAME PROBLEM WHICH ULTIMATELY TURNS OUT TO BE A DEFECTIVE "CRANK SHAFT SENSOR" -- BUT KIA SERVICE JERKS PEOPLE AROUND AND KEEPS THEIR CARS FOR DAYS/WEEKS SAYING THAT THEY "CANNOT RECREATE THE PROBLEM". THIS IS A HUGE SAFETY ISSUE WHEN YOUR VEHICLE JUST SUDDENLY DIES ON THE FREEWAY WITH ABSOLUTELY NO WARNING... NOT EVEN SPUTTERING. I PRINTED OUT SEVERAL CONSUMER ACCOUNTS DESCRIBING MY EXACT PROBLEM--REVEALING IT'S ULTIMATELY THE CRANK SHAFT SENSOR, AND KIA IS REFUSING TO ACKNOWLEDGE THE RELATIONSHIP BETWEEN THEIR REPAIR WORK AND THE LIKELIHOOD THAT IT'S THE CRANK SHAFT SENSOR -- ADMITTEDLY HOLDING MY VEHICLE WITHOUT EVEN REVIEWING THE BASIC DIAGNOSTICS. *TR

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.
