NHTSA recall 13V142000

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.
The remedy
MCI will notify owners and dealers will inspect and replace the bellows pipes, as necessary, free of charge. The recall began on April 29, 2013. Customers may contact MCI at 1-847-285-2000.
