WHILE DRIVING THE VEHICLE DOWN THE ROAD WITH THE HEATED SEAT (DRIVERS SIDE) ON, I BEGAN TO NOTICE A BURNING SMELL AND SMOKE COMING FROM THE PASSENGER SEAT AREA. STOPPED THE VEHICLE TO INSPECT TO FIND A SMOLDERING WIRING HARNESS AND MODULE, THERE WAS A SMALL FLAME. THE FLAME WAS EXTINGUISHED. THE VEHICLE WAS THEN TURNED OFF AND BROUGHT TO A GM DEALERSHIP THAT DIAGNOSED IT AS HAVING A BAD CONNECTOR. DEALERSHIP ALSO STATED THAT THIS IS A COMMON ISSUE ON THESE CARS. IN ORDER TO FIX THIS AND MAKE IT SAFE IT REQUIRED THE MODULE UNDER THE PASSENGER SEAT AND THE CONNECTOR TO BE REPLACED. WAS INFORMED THAT THE NEW MODULE IS AN IMPROVED DESIGN THAT SHOULDN'T HAVE THE SAME ISSUE. ALL SERVICE WAS PERFORMED AND THE VEHICLE AND ACCESSORIES IS NOW FUNCTIONING AS THEY SHOULD. *TR ....UPDATED 09-03-14 *BF UPDATED 09/8/2014 *JS
