Recalls 5

Electronic stability control (ESC)Reported December 19, 2025 · 6,673 vehicles affected

What is wrong: New Flyer of America, Inc. (New Flyer) is recalling certain XD35, XDE35, XE35, XN35, XD40, XDE40, XE40, XHE40, XN40, XT40, XD60, XDE60, XE60, XN60, XT60, and XHE60 transit buses. Please refer to New Flyer's recall report for specific model year information. The antilock braking (ABS) and electronic stability control (ESC) module may lose communication and fail without illuminating the warning lights. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard numbers 121, "Air Brake Systems" and 136, "Electronic Stability Control Systems on Heavy Vehicles."
Risk: An ABS or ESC warning light that fails to illuminate will not alert the driver to the loss of ABS or ESC, increasing the risk of a crash.
Remedy: New Flyer will update the software, free of charge. Owner notification letters were mailed February 17, 2026. Owners may contact New Flyer's customer service at 1‑800‑241‑2947.

Recall number 25V898000 · Recall details

Fuel system, diesel: fuel injection system: fuel railReported May 18, 2021 · 3,600 vehicles affected

Risk: A fuel leak in the presence of an ignition source increases the risk of a fire.
Remedy: New Flyer will inspect the rail threads, and replace the rail as necessary, free of charge. Owner notification letters were mailed on June 28, 2021. Owners may contact New Flyer customer service at 1‑204‑224‑6706. New Flyer's number for this recall is R21-008.

EquipmentReported November 22, 2018 · 463 vehicles affected

What is wrong: New Flyer of America, Inc. (New Flyer) is recalling certain 2015-2017 New Flyer XD40 and XN60, 2015 XD60 and XDE40 and 2013-2017 XN40 vehicles, equipped with certain Kidde Technologies, Inc. (KTI) KDS-25 fire extinguishers as part of the optional fire suppression system. The actuator of the extinguisher may not function properly, preventing the fire extinguisher from discharging the fire suppression agent in the event of a fire.
Risk: If the fire suppression system does not work as intended, it can increase the risk of injury in the event of a fire.
Remedy: New Flyer has notified owners, and KTI will inspect the fire suppression systems and replace the electrical piston actuators, as necessary, free of charge. The recall began on November 29, 2018. Owners may contact New Flyer customer service at 1‑204‑224‑6706. New Flyer's number for this recall is R18-020.

Recall number 18V827000 · Recall details

Service brakes, air: antilockReported January 9, 2018 · 283 vehicles affected

What is wrong: New Flyer of America Inc. (New Flyer) is recalling certain 2017 XD40, XDE40, XN40, XT60, and 2016-2017 XDE60 transit buses. The air brake hose connections for the front axle ABS modulator valves may not be properly tightened, possibly resulting in the air brake hose disconnecting. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 121, "Air Brake Systems."
Risk: If the brake hose disconnects from the ABS modulator valve, there will be no brake force applied to either of the front axle brake assemblies, lengthening the needed braking distance and increasing the risk of a crash.
Remedy: New Flyer will notify owners, and will reconnect the air hose using the proper tightness, free of charge. The recall began on January 11, 2018. Owners may contact New Flyer customer service at 1‑204‑224‑6706. New Flyer's number for this recall is R18-001.

Recall number 18V020000 · Recall details

Seat belts: front: buckle assemblyReported August 30, 2017 · 214 vehicles affected

The seat belt buckle may be stuck in the locked position, preventing the seat belt tongue from being able to be inserted and locked.
Risk: If the seat belt cannot be latched, the bus may be operated without the seat belt being used, increasing the risk of injury in the event of a crash.
Remedy: New Flyer has notified owners and work with the supplier to replace the buckle housings, free of charge. The recall began September 15, 2017. Owners may contact New Flyer customer service at 1‑204‑224‑6706. New Flyers' number for this recall is R17-017.
