What NHTSA recorded
Motor Coach Industries (MCI) is recalling certain 2011-2012 MCI D4000, D4005, D4500 and D4505 coaches equipped with Cummins ISX 12 liter engines. The vehicles may have an incorrectly installed exhaust bellow pipe, resulting in a bend in the pipe which can cause its premature failure.
Possible consequence
If the pipe fails and a diesel regeneration cycle occurs, the hot exhaust gases will increase the risk of a fire.
Remedy
MCI will notify owners and dealers will inspect and replace any deformed or failed bellow pipes if necessary, free of charge. The recall began on June 15, 2017. Owners may contact Motor Industries at 1-800-241-2947. MCI's number for this recall is SB 397B.
