Summary

NHTSA records recall 20V352000, published June 15, 2020 and initiated June 12, 2020. Recalling firm: Motor Coach Industries, Inc; 2020 Mci J4500 | 2019 Mci J4500 | 2018 Mci J4500 | 2019 Mci D45 Crt Le | 2018 Mci D45 Crt Le | 2020 Mci D45 Crt Le | 2018 Mci D4005 | 2018 Mci D4500 | 2018 Mci D4505 | 2019 Mci D4505 | 2019 Mci D4500 | 2020 Mci D4500 | 2019 Mci D4005 | 2020 Mci D4005 | 2020 Mci D4505 | 2019 Mci D4000 | 2020 Mci D4000 | 2018 Mci D4000 — Electrical system: alternator/generator/regulator.

What's the hazard

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.

What to do

MCI will notify the affected owners, and dealers will install a new application code in the Parker VMM multiplex modules increasing the overvoltage threshold limit, free of charge. The recall began July 23, 2020. Owners may contact MCI customer service at 1-800-241-2947. MCI's number for this recall is SB 479.
