140 units potentially affected
The defect: Motor Coach Industries (MCI) is recalling certain 2019-2021 D45CRTLE, J3500, and J4500 coaches, equipped with a rear-mounted bike rack. The vehicle's rear lighting may be obstructed when bikes are installed on the bike rack. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 108, "Lamps, Reflective Devices, and Associated Equipment."
The risk: Obstructed rear lighting may reduce the visibility of the vehicle to other drivers, increasing the risk of a crash.
The remedy: MCI will provide instructions and a kit to add lighting to the rear-mounted bike rack, free of charge. Owner notification letters were mailed August 31, 2023. Owners may contact MCI customer service at 1-800-241-2947.

FUEL SYSTEM, DIESEL:FUEL INJECTION SYSTEM:FUEL RAIL

Dec 15, 2021
1,125 units potentially affected
The defect: Motor Coach Industries (MCI) is recalling certain 2019-2022 D4000 ISTV, D4500, 2021 D4000, D4520, 2020-2021 D4505, D4005, 2020-2022 D45CRTLE, and 2019-2021 J4500 vehicles equipped with certain Cummins X12 diesel engines. The fuel tubes between the fuel rail and the injectors for cylinders four, five, and six may fatigue and crack, which can result in a high pressure fuel leak.
The risk: A high pressure fuel leak in the presence of an ignition source can increase the risk of a fire.
The remedy: On engines with 75 miles or less, Cummins dealers will install vibration isolators to the fuel tubes. Engines with more than 75 miles will receive new fuel tubes with vibration isolators. Repairs will be performed free of charge. Owner notification letters were mailed March 11, 2022. Owners may contact MCI customer service at 1-800-241-2947. MCI's number for this recall is R21-028.

Aug 31, 2020
1,561 units potentially affected
The defect: Motor Coach Industries (MCI) is recalling certain 2017-2020 J4500 motor coaches. The coolant hose may fail, resulting in a low coolant warning followed by an engine shut down sequence, as well as the potential for engine coolant spilling on the roadway.
The risk: The spilled coolant may increase the risk of a crash. Additionally, transferring passengers from the disabled bus can increase their risk of injury.
The remedy: MCI will notify owners, and dealers will replace the coolant hose, free of charge. The recall began October 30, 2020. Owners may contact MCI customer service at 1-800-241-2947. MCI's number for this recall is SB 486.

ELECTRICAL SYSTEM:ALTERNATOR/GENERATOR/REGULATOR

Jun 12, 2020
1,067 units potentially affected
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.
The risk: If the engine shuts down or loses power while the vehicle is in motion, this may increase the risk of a crash.
The 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.

SEAT BELTS

Apr 29, 2020
641 units potentially affected
The defect: Motor Coach Industries (MCI) is recalling certain 2015-2016 D4000, 2015-2020 D4500 and D4505, 2016-2020 J4500, 2018 J3500, and 2017 D4005 buses. The seat belts may not extend from the retracted position, rendering the seat belt unusable. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standards (FMVSS) number 208, "Occupant Crash Protection," and number 209, "Seat Belt Assemblies."
The risk: Inability to use the seat belt may increase the risk of injury in the event of a crash.
The remedy: MCI will notify the affected owners, and dealers will inspect and replace the seat belts, as necessary, free of charge. MCI issued owners an interim notification June 26, 2020. The recall began January 13, 2021. Owners may contact MCI customer service at 1-800-241-2947. MCI's number for this recall is SB 482.

What a recall is

Safety recall
A safety recall is issued when a manufacturer or NHTSA determines that a vehicle has a safety-related defect or does not comply with a federal motor vehicle safety standard. Recall repairs are free. Whether a specific vehicle is covered depends on its VIN — a recall listed for a model year does not necessarily apply to every vehicle of that year.
Safety investigation
NHTSA opens an investigation to examine whether a safety defect may exist. An open investigation is not a determination that a defect exists, and many investigations close without a recall. Investigations can, however, lead to one.
Manufacturer communication
Manufacturers file copies of the bulletins they send to dealers with NHTSA. These often describe diagnostic or repair procedures for a known condition. They are not recalls: repairs described in a bulletin are usually only free if the vehicle is still under warranty or the manufacturer has extended coverage.

Safety investigations

NHTSA inquiries naming this vehicle. An investigation is not a finding of a defect, and it is not a recall.

PE20001ClosedPreliminary Evaluation

Supply and return heater hose rupture

Opened Mar 13, 2020
Closed Sep 21, 2020

By letter dated August 31, 2020, Motor Coach Industries (MCI) notified the Office of Defects Investigation (ODI) of a safety defect that may exist in certain model year (MY) 2017-2020 J4500 vehicles. An ODI review of Early Warning Reporting (EWR) submissions by MCI, on MY 2017-2019 J4500 buses, identified ruptured heater hoses on multiple motor coaches leading to the vehicles becoming disabled. ODI communications with fleets found that a low coolant level light with an audible warning would provide notice to the bus driver to pull off the roadway before the bus shut down to prevent catastrophic engine damage. According to the fleets interviewed, there is not sufficient time between the warning and the engine shutting down to allow the driver to pull to a safe location. Multiple reports/interviews describe buses requiring passenger transfer to a second bus at roadside. Analysis of data provided by MCI in response to an ODI Information Request (IR) letter showed an elevated frequency of heater hose ruptures. The heater hoses may fail, resulting in a low coolant warning followed by an engine shut down sequence, as well as the potential for engine coolant spilling on the roadway. Following discussions with ODI about the elevated failure rates on the heater hoses, MCI decided to conduct safety recall 20V-526.With recall action 20V-526 taken by MCI, this investigation is closed. Further use of agency resources does not appear to be warranted.The closing of this investigation does not constitute a finding by NHTSA that a safety-related defect does not exist on other model or MY vehicles outside of the recall scope. The agency reserves the right to take further action if warranted by the circumstances.The ODI report cited above can be reviewed at: http://www-odi.nhtsa.dot.gov/owners/SearchNHTSAID Using the following identification number: 10168841
