2007 KIA SEDONA Structure Problems

VAN STARTED MAKING CLUNKING / GRINDING NOISE WHEN TURNING AND/OR HITTING SMALL BUMPS (BIGGER BUMP BIGGER NOISE). DEALER SAYS 3 OF 4 BODY BUSHINGS CRACKING / WORN. DEALER STATES NOT A COMMON PROBLEM. SAID HAS NEVER SEEN BEFORE YET HAS PARTS IN STOCK TO FIX FOR $850. I DO NOT BELIEVE THAT A VAN THAT IS 6 YEARS OLD WITH 72,000 MILES THAT IS DRIVEN EXCLUSIVELY ON PAVED ROADS SHOULD HAVE BODY BUSHINGS FAILING. I HAVE SEEN NUMEROUS COMPLAINTS ABOUT THIS ISSUE SPECIFICALLY, AND OTHERS THAT SOUND SIMILAR BUT HAVE GONE UNDIAGNOSED, RELATING TO 2006 / 07 & 08 SEDONA'S. MIGHT THIS BE AN ISSUE COVERED IN A RECALL? *TR

OCCASIONALLY, THE POWER SLIDING DOOR ON THE DRIVERS SIDE CLOSES AND THEN REOPENS ABOUT 6-12" AND HAS TO BE CLOSED BY HAND. THERE HAVE BEEN SEVERAL TIMES WHEN THE SAME DOOR OPENS ALL THE WAY AND IT CAN'T BE CLOSED, EITHER BY POWER OR BY HAND. IT WILL REMAIN OPEN UNTIL IT GETS READY FOR YOU TO CLOSE IT. THE TIME FRAME VARIES BUT USUALLY 10-15 MINUTES. SEVERAL TIMES, WHILE DRIVING WITH ALL OF THE DOORS CLOSED AND LOCKED, THE SAME SLIDING DOOR WILL OPEN A COUPLE OF INCHES AND I HAVE TO STOP AND MANUALLY CLOSE IT. THE VAN HAS BEEN IN THE SHOP SEVERAL TIMES AND EACH OF THE DESCRIBED INCIDENTS STILL HAPPEN FROM TIME TO TIME. THE REPAIR TECHNICIANS CANNOT DUPLICATE THE PROBLEM SO NO CORRECTIVE ACTION CAN BE TAKEN. IT'S JUST A MATTER OF TIME BEFORE SOMEONE FALLS OUT OF THE VEHICLE WHILE IT IS MOVING...
