Recall Summary:Tiffin is recalling certain model year 2011, 2012, and 2013 recreational vehicles, models phaeton and zephyr, equipped with a cummins isb, isc, isl, or isx 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.
