Plain-English summary

Cummins Inc. is recalling certain ISB6.7, ISC8.3, ISL9, ISX11.9, and ISX15 engines that were shipped to vehicle manufacturers between September 2010 and December 2010. These engines are installed in recreational vehicles, emergency vehicles, buses, and certain truck applications. The recall involves a V-band clamp assembly used to connect the inlet and outlet cone sections to the diesel oxidation catalyst (DOC)/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. Cummins is working with vehicle manufacturers to identify and notify owners. Affected owners may contact Cummins at 1-812-377-5000 or their vehicle manufacturer for corrective action. Owners may also contact the National Highway Traffic Safety Administration's Vehicle Safety Hotline at 1-888-327-4236 or visit safercar.gov.
