Our assessment, not the agency’s: severity 4/5 (Severe).

The hazard poses a serious risk of illness, injury, or structural failure. Stop using the product immediately and contact the manufacturer for a refund or repair.

Our severity reasoning: The recall involves a structural defect in the exhaust system that creates a risk of fire and road hazards, meeting the rubric criteria for 'Severe' severity due to significant injury/property-damage potential.

Plain-English summary

Motor Coach Industries, Inc. (MCI) is recalling certain model year 2011 E4500 and J4500 motor coaches manufactured between December 2010 and January 2011. These vehicles are equipped with a Cummins ISX 11.9 diesel engine. The recall involves 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 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.

Owners should contact MCI at 1-800-241-2947 or Cummins at 1-812-377-5000 for more information. Repairs will be performed by authorized Cummins dealers free of charge. The safety recall began on September 19, 2011. Owners may also contact the NHTSA Vehicle Safety Hotline at 1-888-327-4236.
