Among the ninety (90) recalls the NHTSA announced this past month came news of the following:

Logo - Motor Coach Industries ("MCI")Motor Coach Industries (“MCI”), a Des Plaines, Illinois establishment and a subsidiary of New Flyer (part of the NFI Group) of Winnipeg, Manitoba recalled an estimated 918 model year 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 marketed, sold and delivered in the United States.

Recall Category: Electrical System – Overvoltage Alternator may cause engine shutdown

NHTSA Safety Notification 20V352000 reports 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.

According to the NHTSA, if the engine shuts down or loses power while the vehicle is in motion, this may increase the risk of a crash, MVA or other impact event with consequential injury and/or life-changing results.

MCI will notify the affected registered 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 is expected to begin July 10, 2020. Owners may contact MCI Customer Service toll-free at 1-800-241-2947 during normal business hours, Monday to Friday, Central Standard Time (“CST”). MCI’s designation for this recall is SB 479.

You may also contact the US National Highway Traffic Safety Administration Vehicle Safety Hotline toll-free at 1-888-327-4236 (TTY 1-800-424-9153) during normal business hours, Eastern Standard Time, or visit
