Defect and consequence

Defect: 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.".

Why it matters: 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.
