Summary
Daimler trucks is recalling certain model year 2011- 2012 thomas built saf-t-liner C2, saf-t-liner mvp-ef, and saf-t-liner hdx school buses manufactured from September 1, 2010, through December 31, 2010, equipped with a cummins isx or isl 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
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.
Remedy
Daimler trucks is working with cummins to identify and notify owners of the recall campaign. 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.

Vehicles covered

As listed by NHTSA. A recall usually covers only some vehicles of each model and year, often a production date range.

Has your Thomas Built been repaired?

Recalls here come from NHTSA’s records for the model and year. Not every vehicle of a model is included in every recall, and this site can’t see whether a repair has been done. Only a VIN lookup can tell you that.

NHTSA’s VIN search doesn’t show recalls that were already repaired, recalls more than 15 years old, or some small manufacturers’ recalls. A Thomas Built dealer can also check your VIN. Recall repairs are free.
