2011 Tiffin Allegro BUS & 2011 Tiffin Phaeton recall: engine

⚠️ What's wrong

Tiffin motorhomes is recalling certain model year 2011 Allegro BUS and Phaeton recreational vehicles built on the powerglide chassis equipped with a cummins isx 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.
