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.
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.
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.
Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to www.safercar.gov.
