THE EMISSIONS TUBES HAVE CONSTANTLY BURNED OUT OF THIS TRUCK. THEY HAVE BEEN REPLACED NUMEROUS TIMES! THE DEALER STATED THAT THESE PARTICULAR PARTS HAVE BEEN REDESIGNED BY FORD TWICE. THIS DEFECT HAS CAUSED TWO MINOR FIRES IN THE FIREWALL. WE HAVE BEEN UNABLE TO GET A FULL ACCOUNTING OF ALL WORK DONE AT ALL THE DIFFERENT DEALERSHIPS IT HAS BEEN IN. I KNOW FORD CAN PULL UP ALL WARRANTED WORK DONE BY VIN HOWEVER THEY WILL NOT DO SO. I WAS TOLD BY A FOREMAN AT A FORD TRUCK SERVICE CENTER IN CULLMAN, ALABAMA THAT THESE PARTICULAR TRUCKS WERE PRONE TO THIS DEFECT AND MOST PEOPLE DID NOT REALIZE THIS WAS A FACROTY PROBLEM AND TRADED THEM OFF. WE CANNOT AFFORD TO "TRADE IT OFF" AND WOULD BE LIABLE IF WE DID NOT LET PROPLE KNOW OF THIS PROBLEM. CURRENTLY OUR EXTENDED WARRANTY HAS EXPIRED AND ALL 4 TUBES ARE BURNOUT.*AK
