MCI J4500

EQUIPMENT:OTHER:LABELS

Motor Coach Industries (MCI) is recalling certain 2025 D4520, D45CRTLE, D45CRT, J3500, and 2025-2026 J4500 buses. The emergency exit label may be placed in the incorrect location. As such, these vehicles fail to conform to Federal Motor Vehicle Safety Standard (FMVSS) number 217, "Bus Emergency Exits and Window Retention and Release."

Risk: Incorrectly located labels may prevent or delay the use of the emergency exit, increasing the risk of injury.

EQUIPMENT:MECHANICAL:CARRIER/RACK

Motor Coach Industries (MCI) is recalling certain 2019-2021 D45CRTLE, J3500, and J4500 coaches, equipped with a rear-mounted bike rack. The vehicle's rear lighting may be obstructed when bikes are installed on the bike rack. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 108, "Lamps, Reflective Devices, and Associated Equipment."

Risk: Obstructed rear lighting may reduce the visibility of the vehicle to other drivers, increasing the risk of a crash.

FUEL SYSTEM, DIESEL:FUEL INJECTION SYSTEM:FUEL RAIL

Motor Coach Industries (MCI) is recalling certain 2019-2022 D4000 ISTV, D4500, 2021 D4000, D4520, 2020-2021 D4505, D4005, 2020-2022 D45CRTLE, and 2019-2021 J4500 vehicles equipped with certain Cummins X12 diesel engines. The fuel tubes between the fuel rail and the injectors for cylinders four, five, and six may fatigue and crack, which can result in a high pressure fuel leak.

Risk: A high pressure fuel leak in the presence of an ignition source can increase the risk of a fire.

EQUIPMENT ADAPTIVE/MOBILITY:WHEELCHAIR LIFT/RAMP

Motor Coach Industries (MCI) is recalling certain 2005-2009 E4500 and 2005-2012 J4500 motorcoaches equipped with Ricon Baylift Wheelchair Lifts. When the lift's outer barrier is fully deployed, it may not withstand a sufficient amount of force, which could cause it to fail. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 403, "Platform Lift Systems," and number 404, "Platform lift installations."

Risk: In the event that a mobility device pushes into the outer barrier, the barrier may fail, increasing the risk of injury for the lift occupant.

ELECTRICAL SYSTEM:12V/24V/48V BATTERY:CABLES

Motor Coach Industries (MCI) is recalling certain 2018-2021 J4500 and 2018-2020 D45CRTLE vehicles. The power cables may have been improperly installed and routed in the vehicle battery compartment, which may result in chafing.

Risk: The power cables may chafe, increasing the risk of a fire.

ELECTRICAL SYSTEM

Motor Coach Industries (MCI) is recalling certain 2018 D4000, 2018-2020 D4005, D4000ISTV, 2017-2020 D4500, D4505, 2018-2021 J3500, 2017-2021 J4500, 2020 D4520, and 2018-2021 D45CRTLE motorcoaches. The Main Distribution Panel (MDP) located within the battery compartment contains a circuit board that may fail.

Risk: MDP circuit board failure can result in a fire or an unexpected vehicle shutdown, increasing the risk of a crash.

FUEL SYSTEM, DIESEL:FUEL INJECTION SYSTEM:FUEL RAIL

Motor Coach Industries (MCI) is recalling certain 2017-2018 D4000, 2017-2019 D4005, D4000ISTV, D4505, 2017-2020 D4500, J4500, 2018-2020 D45CRTLE, and 2018-2021 J3500 vehicles. The sealing washer may not seat correctly in the pilot bore holes, allowing the high pressure fuel rail assembly to leak.

Risk: A fuel leak in the presence of an ignition source increases the risk of a fire.

ENGINE AND ENGINE COOLING:COOLING SYSTEM:HOSES/LINES/PIPING/FITTINGS

Motor Coach Industries (MCI) is recalling certain 2017-2020 J4500 motor coaches. The coolant hose may fail, resulting in a low coolant warning followed by an engine shut down sequence, as well as the potential for engine coolant spilling on the roadway.

Risk: The spilled coolant may increase the risk of a crash. Additionally, transferring passengers from the disabled bus can increase their risk of injury.

ELECTRICAL SYSTEM:ALTERNATOR/GENERATOR/REGULATOR

Motor Coach Industries (MCI) is recalling certain 2018-2020 D4000, D4005, D4500, D4505 and D45CRTLE buses manufactured with electric cooling fans (E-fan) for the radiator and charge air cooler, Borg Warner 55SI model dual alternator configuration (with a sense stud and wire), and Parker Vansco Multiplexing Module (VMM) Multiplex system. A build-up of debris, corrosion, and/or water flow could cause a high resistance path to ground for the sense stud on the back of the alternator and cause the alternator to produce excessive voltage output, which may exceed the threshold limit currently programmed in the VMM and result in a loss of engine power and vehicle shutdown.

Risk: If the engine shuts down or loses power while the vehicle is in motion, this may increase the risk of a crash.
