The defect
Motor Coach Industries (MCI) is recalling certain model year 2012-2013 D4000, D4000ISTV, D4005, D4500, and D4505 motorcoaches manufactured from May 2012 through December 2012 and equipped with a Cummins ISX EPA 2010 engine. In the affected buses, the bellows pipe in the exhaust system may have been incorrectly assembled, which could result in a failure of the pipe during operation.
The risk
During a regeneration process to clean exhaust emissions, if the bellows pipe has failed, the hot exhaust gases may not be contained, resulting in a fire.
