2011 MCI E4500; 2011 MCI J4500
Check against the official notice below — it lists the full affected range.
Motor Coach Industries is recalling certain 2011 E4500 and J4500 motor coaches manufactured between December 2010 and January 2011 that are equipped with Cummins ISX 11.9 diesel engines. The vehicles contain V-band clamp assemblies with T-bolts that can fracture and fail under stress or load, causing the clamps to loosen and the inlet or outlet sections of the diesel oxidation catalyst/diesel particulate filter housing to disconnect.
If these sections disconnect, hot exhaust gases can vent before exiting the tailpipe, creating a fire risk. If both clamps fail, the housing itself may detach completely and create a road hazard. MCI will notify owners and will perform repairs at authorized Cummins dealers at no charge. Owners should contact MCI at 1-800-241-2947 or Cummins at 1-812-377-5000 for more information regarding the recall.
