Recalls
47 campaigns cover the J4500; the latest 12 are below.
Motor Coach Industries (MCI) is recalling certain 102DL3, 102D3, MC12PTV, E4500, D4000, 102D3ISTV, D4500, J4500, D4000ISTV, D4005, D4505, and J3500 transit buses. Please refer to MCI's recall report for specific model year information. The front door lower curb view glazing material is incorrect. As such, these vehicles fail to conform to Federal Motor Vehicle Safety Standard (FMVSS) number 205, "Glazing Materials."
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."
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."
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.
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.
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."
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.
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.
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.
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.
Motor Coach Industries (MCI) is recalling certain 2015-2016 D4000, 2015-2020 D4500 and D4505, 2016-2020 J4500, 2018 J3500, and 2017 D4005 buses. The seat belts may not extend from the retracted position, rendering the seat belt unusable. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standards (FMVSS) number 208, "Occupant Crash Protection," and number 209, "Seat Belt Assemblies."
Motor Coach Industries (MCI) is recalling certain model year 2014-2019 J4500 and 2018-2019 J3500 motor coaches. The brake hoses may crack or otherwise fail resulting in an air leak. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 121, "Air Brake Systems."
