| Defect 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. |
| Consequence summary | 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. |
| Corrective action | Tiffins is working with cummins to identify and notify owners of the recall campaign. Repairs will be performed by authorized cummins dealers free of charge. Owners may contact cummins at 1-812-377-5000 or tiffins at 256-356-8661. |
