The problem
Motor Coach Industries (MCI) is recalling certain 2011-2016 D4500, D4505, D4000, D4005, and D4000 ISTV motor coaches equipped with ISX engines. Due to vibrations, the exhaust bellow pipes develop a hole.
The risk
If the pipe develops a hole, during a regeneration cycle, hot exhaust gases may leak out, increasing the risk of a fire.
The fix
MCI will notify owners, and dealers will replace the bellows pipe assembly with an improved part, free of charge. The recall began July 10, 2018. Owners may contact MCI customer service at 1-800-241-2947.
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.
