An official Health Canada notice concerns Tiffin. On certain motorhomes equipped with a Cummins engine, the V-band clamps 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. Should this occur, hot exhaust gases can vent prior to exiting the tailpipe, creating a risk of combustion or damage to adjacent materials, which could result in a vehicle fire. If both clamps fail, the DOC/DPF housing could detach completely, separate from the vehicle, and strike another vehicle, stationary object, or bystander. These issues could result in property damage and/or personal injury. Correction: Cummins will install updated V-band clamps. Published 2012-06-01.
