NHTSA's recall notice

As NHTSA's recall record states it for campaign 18V309000.

Defect description

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.

Safety consequence

If the pipe develops a hole, during a regeneration cycle, hot exhaust gases may leak out, increasing the risk of a fire.

Manufacturer remedy

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.

Notes

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.
