What this recall covers
- The defect
- TIFFIN MOTORHOMES, INC. (TIFFIN) IS RECALLING CERTAIN MODEL YEAR 2011 ALLEGRO AND PHAETON RECREATIONAL VEHICLES BUILT ON FREIGHTLINER CHASSIS AND EQUIPPED WITH A CUMMINS ISC, ISX, ISM, OR ISL DIESEL ENGINE. THE V-BAND CLAMP ASSEMBLY, PART NUMBERS Q187684, Q187685, AND Q187686, USED TO CONNECT THE INLET AND OUTLET CONE SECTIONS TO THE DIESEL OXIDATION CATALYST (DOC)/DIESEL PARTICULATE FILTER (DPF) INCLUDE A T-BOLT WHICH CAN FRACTURE AND FAIL WHEN SUBJECTED TO STRESS OR LOAD. A FRACTURE OR FAILURE OF THE T-BOLT MAY CAUSE THE CLAMP TO LOOSEN AND THE INLET OR OUTLET SECTIONS ATTACHED TO THE DOC/DPF HOUSING TO DISCONNECT.
- The risk
- IF THE INLET OR OUTLET SECTIONS DISCONNECT, HOT EXHAUST GASES CAN VENT PRIOR TO EXITING THE TAILPIPE, CREATING THE RISK OF COMBUSTION AND A FIRE. IF BOTH CLAMPS FAIL, THERE IS A RISK IN SOME APPLICATIONS THAT THE DOC/DPF HOUSING MAY DETACH COMPLETELY, CREATING A ROAD HAZARD.
- The fix
