NHTSA Complaint #10269907 — 2003 KIA SEDONA EX

WE FIRST GOT OUR (USED) KIA SEDONA OCT. OF 2007. IT HAD ABOUT 45,000 MILES ON IT WHEN WE GOT IT- AND NOW IT HAS ABOUT 74,000. 2 MONTHS INTO HAVING IT THE CHECK ENGINE LIGHT WOULD COME ON WHENEVER THE TEMPERATURE DROPPED BELOW 20 DEGREES(F). THE CHECK ENGINE LIGHT WOULD USUALLY GO OFF BY THE NEXT DAY IF IT WAS WARMER OUT OR WOULD STAY ON FOR UP TO 3 DAYS IF IT WAS VERY COLD) IT STARTED TO BUCK A LOT (ABOUT 6 MONTHS INTO HAVING IT) AND WE BROUGHT IT TO THE SHOP AND HAD THE SPARK PLUGS, WIRES, BOOTS, AND COILS REPLACED. ABOUT A MONTH AFTER THOSE WERE REPLACED THE CATALYTIC CONVERTER WENT AND WE NEEDED TO REPLACE THAT. THE CHECK ENGINE LIGHT STILL COMES ON WHEN THE TEMPERATURES DROP-BUT THEY CANT FIGURE OUT WHY. NOW THE CAR STALLS (AND BUCKS) AT VARIOUS TIMES FOR NO REASON. WE'VE TAKEN IT TO THE SHOP BUT THEY CANT FIND ANYTHING WRONG WITH IT. THE RADIO WILL TURN ITSELF UP ALL THE WAY AT DIFFERENT TIME (USUALLY IF IDLING). SOMETIMES THE RADIO STATIONS WILL REVERT BACK TO THE PRESETS SO I HAVE TO RESET ALL OF THE STATIONS I HAD SET. (THIS USUALLY HAPPENS WHEN IT'S COLD OUT) WE WERE STUPID AND BOUGHT THE EXTENDED WARRANTY (WHICH DOESN'T COVER ANYTHING THAT HAS GONE WRONG!- ALTHOUGH THE CATALYTIC CONVERTER WAS COVERED BY THE ORIGINAL WARRANTY) WE OWE TOO MUCH ON IT TO SELL IT OR TRADE IT IN SO NOW WE'RE STUCK WITH AN UNRELIABLE VEHICLE THAT I AM SCARED TO DRIVE MY DAUGHTER AROUND IN- THERE'S NO TELLING WHERE THE CAR MIGHT STALL NEXT! WHAT CAN WE DO? *TR
