What the defect is
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 could happen
If the engine shuts down or loses power while the vehicle is in motion, this may increase the risk of a crash.
What gets fixed
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.

Your rights
A safety recall repair is free. Under US federal law the manufacturer must fix a safety defect at no cost to you — no charge for parts, labor or diagnosis — whether or not you are the original owner. A dealer cannot charge you for recall work, and cannot require you to have bought the vehicle from them.
That entitlement is not unlimited. It applies where the vehicle was first sold less than 15 years before the recall was announced — 5 years for tires. Past that a manufacturer may still do the repair free of charge, and many do, but they are no longer obliged to. This recall was reported on 12 June 2020.
To arrange the repair, contact any franchised dealer for the brand. If a dealer refuses the work or tries to charge for it, you can report that to NHTSA at nhtsa.gov/recalls or on 1-888-327-4236.

Everything on this page — the models listed, the build dates and the repair figures — comes from the manufacturer's filing to NHTSA and describes the vehicle line as a whole, not any individual car. Only the manufacturer can confirm whether a specific vehicle is affected, and whether its recall work has already been carried out. Check yours by VIN and read the official notice at nhtsa.gov/recalls.
Additional notes
Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to www.safercar.gov.
Check your own vehicle
This page describes the recall, not any one car. To see which recalls cover a specific vehicle, search by make, model and year.
A VIN lookup here identifies your vehicle and shows recalls issued for that make, model and year. It cannot tell you what is still open on your individual car - only the manufacturer knows that. Search by VIN instead, or check your VIN at nhtsa.gov for whether a recall is still open on your individual car.
