Plain-English summary

Daimler Trucks North America is recalling 1,825 model year 2011-2012 Thomas Built Saf-T-Liner C2, Saf-T-Liner MVP-EF, and Saf-T-Liner HDX school buses. These vehicles were manufactured between September 1, 2010, and December 31, 2010, and are equipped with a Cummins ISX or ISL diesel engine.

The recall addresses a defect in 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 these 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. Daimler Trucks is working with Cummins to identify and notify owners. 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 Daimler Trucks at 1-800-547-0712.
