Transport Canada recalls

Electrical#2020276June 17, 2020
111 units affected
Issue: On certain buses, a build-up of corrosion on the alternator connection could cause it to malfunction. If this happens, the alternator voltage output may increase. As a result, the control module may switch off the engine and cause a vehicle shutdown. Safety Risk: A sudden loss of engine power and vehicle shutdown could increase the risk of a crash. Corrective Actions: Motor Coach Industries (MCI) will notify owners by mail and instruct you to take your bus to an authorized repair facility to update the software in the Vehicle Multiplexing Module (VMM). MCI also recommends periodically inspecting, cleaning and re-applying corrosion inhibitor to the alternator.

U.S. NHTSA recalls

ELECTRICAL SYSTEM:ALTERNATOR/GENERATOR/REGULATOR#20V352000June 12, 2020
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.
Remedy: 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.
