MotorCoach Industries J4500 Air Brake Recall

MotorCoach Industries (MCI) is recalling certain model year 2017 J4500 motorcoaches manufactured March 14, 2016, to August 23, 2016. The affected vehicles may experience a multiplexing programming error that will not provide any visual or audible warnings if the vehicle’s primary service brake air reservoir system has low pressure. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 121, “Air Brake Systems.”


If the driver is unaware that the service brakes have low air pressure, the brakes may apply automatically, increasing the risk of a crash.


Motor Coach Industries will notify owners, and dealers will correct the programming of the multiplexing system, free of charge. The recall is expected to begin in October 2016. Owners may contact MCI customer service at 1-800-241-2947. MCI’s number for this recall is SB 439.


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
