ELECTRICAL SYSTEM:ALTERNATOR/GENERATOR/REGULATOR
- The defect
- 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 it can cause
- If the engine shuts down or loses power while the vehicle is in motion, this may increase the risk of a crash.
- What the dealer does
- 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.
- NHTSA's note
- 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.
The repair is free, whatever the age or mileage of the vehicle, and whether or not you are the original owner.
Which vehicles
A recall reaches a range of VINs inside these model years, not every car built in them. Yours may not be covered even if it is listed here, and the only way to find out is NHTSA's own VIN lookup .

How this campaign compares
At 1,067 vehicles this is a bigger campaign than 59% of the 19,818 vehicle recalls filed since 1995 whose size NHTSA published. The middle campaign on file covers 472. It covers model years 2018 to 2020, so the oldest vehicles on it were 2 model years old when the defect was reported to NHTSA.
MCI vehicles have been recalled over the electrical system 10 times before this, most recently in April 2018 as 18V223000. That is not evidence the earlier repair failed.
The vehicles on this campaign carry 11 other recalls published here, the newest being: 25V853000 (structure), 24V073000 (equipment adaptive/mobility), 23V240000 (equipment), 21V971000 (fuel system, diesel).
Check your own car
A VIN check is the only answer for a specific vehicle, and it also shows every other open recall on it, which is usually the reason it is worth doing rather than reading one campaign.
Filed by Motor Coach Industries with NHTSA on June 12, 2020 as campaign 20V352000. Every word of the defect, consequence and remedy above is NHTSA's published record of that filing, not a summary of it.
