Mci J4500
The defect
Motor Coach Industries (MCI) is recalling certain 2018 MCI J4500 buses. The primary air line was incorrectly hooked to the secondary air pressure gauge and the secondary air line was hooked to the primary air pressure gauge. As such, these buses fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 121, "Air Brake Systems."
The risk
The incorrect air pressure readings may increase the risk of a crash by delaying the driver's reaction to addressing the low air condition.
The remedy
MCI will notify owners, and dealers will inspect the air lines for proper connection, repairing them as necessary, free of charge. The recall began on December 12, 2017. Owners may contact MCI customer service at 1-800-241-29471. MCI's number for this recall is SB 455.
