NHTSA Complaint #10090609 — 2000 KIA SEPHIA

I'VE HAD MANY PROBLEMS WITH THE CATALYTIC CONVERTERS DISINTEGRATING FROM WITHIN. I'VE HAD THEM REPLACED MANY TIMES AT LEAST 3 OR 4 TIMES IN THE LAST 2 YRS THE MOST RECENT WAS THIS SUMMER ABOUT 2 MONTHS AGO. I AM HAVING THIS PROBLEM AGAIN IT BEGINS TO ACT LIKE IT'S GOING TO STALL, THEN STARTS VIGOUROUSLY SHAKING, AND IT ALSO LOSES ACCELERATION SPEED. I'LL BE DRIVING AND ALL OF A SUDDEN IT STARTS ACTING UP AND LOSING SPEED AND IT WONT GO ANY HIGHER THAN 20 MPH OR SO. THIS IS A CONTINUOUS PROBLEM AND ONE THAT I CONSIDER VERY DANGEROUS BECAUSE I COULD BE DRIVING ON A BUSY STREET OR A HWY AND I LOSE ACCELERATION SPEED AND IT SHAKES. THIS POSES A PROBLEM TO MY OWN SAFETY AND THAT OF OTHERS DRIVING WHILE THESE EFFECTS OCCUR. I'M SCARED IT WILL BLOW UP, BURN UP, OR FALL APART WITH ALL THE SHAKING OR EVEN STALL AND CAUSE A MAJOR ACCIDENT. PLEASE HELP!!! I'VE TAKEN IT NUMEROUS TIMES TO THE DEALERSHIP TO GET THIS FIXED AND I'VE ONLY GOTTEN A TEMPORARY FIX AS YOU CAN SEE. IF ITS NOT THE CATALYTIC CONVERTER, ITS THE FUEL INJECTORS, OR THE FUEL GAUGE, IT'S ALWAYS ONE THING OR ANTHER. THIS CAR IS A LEMON!!! *AK
