Plain-English summary

Tiffin Motorhomes, Inc. is recalling certain model year 2011 Allegro Bus and Phaeton recreational vehicles built on the PowerGlide chassis. These vehicles are equipped with a Cummins ISX or ISL diesel engine. The recall involves 179 affected units.

The defect involves the V-band clamp assembly used to connect the inlet and outlet cone sections to the diesel oxidation catalyst (DOC)/diesel particulate filter (DPF). The assembly includes a T-bolt that can fracture and fail when subjected to stress or load. If the T-bolt fails, the clamp may loosen, causing the inlet or outlet sections to disconnect from the DOC/DPF housing.

If the sections disconnect, hot exhaust gases can vent before exiting the tailpipe, creating a risk of combustion and fire. In some applications, if both clamps fail, the DOC/DPF housing may detach completely, creating a road hazard. Repairs will be performed by authorized Cummins dealers free of charge. The safety recall began on October 10, 2011. Owners may contact Cummins at 1-812-377-5000 or Tiffin Motorhomes at 1-256-356-8661.
