NHTSA Complaint #11093752 — 2013 TIFFIN ALLEGRO BUS

COOLING SYSTEM FAN DRIVE BELT TENSIONER DEVELOPS CRACKS THAT PROGRESS TO THE POINT OF CATASTROPHIC FAILURE WHERE HALF THE BRACKET END AND TWO HEAVY PULLEYS ARE EJECTED FROM THE VEHICLE BY THE FAST MOVING FAN BELT.. THIS HAS BEEN A KNOWN PROBLEM AND TIFFIN HAS REDESIGNED THE BRACKET AND IS REPAIRING THEM AS THEY FAIL. THERE HAVE BEEN NUMEROUS FAILURES AND POSTS ABOUT THEM POSTED IN THE ON-LINE RECREATIONAL VEHICLE FORUMS. AS A RESULT OF THESE POSTS, I ADDED A CHECK OF THIS BRACKET TO MY MAINTENANCE CHECKLIST. A MAJOR MAINTENANCE CYCLE WAS COMPLETED JUST BEFORE CHRISTMAS AND NO PROBLEM WAS FOUND. ANOTHER MAINTENANCE CYCLE WAS COMPLETED THIS MAY, APPROXIMATELY 6000 MILES LATER, AND THE CRACKS WERE FOUND. TIFFIN WAS NOTIFIED AND A REPLACEMENT BRACKET IS BEING SENT TO ME. *DT
