Plain-English summary

Nova Bus Incorporated is recalling certain model year 2010 LFS buses manufactured between September 1, 2010, and December 31, 2010. These vehicles are equipped with Cummins ISB, ISX, ISC, 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 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.

Owners should contact Cummins at 1-812-377-5000 to schedule a repair. Authorized Cummins dealers will perform the repairs free of charge. The safety recall began on October 10, 2011. Owners may also contact the NHTSA Vehicle Safety Hotline at 1-888-327-4236 or visit safercar.gov for more information.
