Plain-English summary

Tiffin Motorhomes, Inc. is recalling certain model year 2011 Allegro and Phaeton recreational vehicles built on Freightliner chassis. These vehicles are equipped with Cummins ISC, ISX, ISM, or ISL diesel engines. The recall involves the V-band clamp assembly used to connect the inlet and outlet cone sections to the diesel oxidation catalyst (DOC) and diesel particulate filter (DPF).

The defect involves a T-bolt within the clamp assembly 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 attached to the DOC/DPF housing to disconnect. This disconnection allows hot exhaust gases to 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.

The safety recall began on October 10, 2011. Tiffin is working with Cummins to identify and notify owners. Repairs will be performed by authorized Cummins dealers free of charge. Owners may contact Cummins at 1-812-377-5000 or Tiffin at 1-256-356-8661. Owners may also contact the NHTSA Vehicle Safety Hotline at 1-888-327-4236.
