2009 KIA SEDONA BOUGHT NEW IN DECEMBER OF 2009. IN MARCH ENGINE STARTED TO SEEM VERY LOUD. CHECK ENGINE LIGHT CAME ON IN EARLY APRIL. TAKEN TO DEALER AND THEY REPLACED THE MASS AIR FLOW SENSOR. CHECK ENGINE LIGHT CAME ON AND WAS IN SHOP 3 MORE TIMES BEFORE THEY UPDATED THE SOFTWARE IN AUGUST. CHECK ENGINE LIGHT DOESN'T COME ON BUT THE ENGINE STILL SEEMS VERY LOUD AND VAN VIBRATES AND RUMBLES WHEN FIRST STARTED - ESPECIALLY AFTER SITTING FOR SEVERAL HOURS OR OVERNIGHT. ENGINE SOUNDS LOUD WHILE DRIVING AND SOMETIMES REVS LOUDLY WHEN ACCELERATING. *TR
