Recalls, owner-reported complaints, investigations and safety data

Owner complaintsComplaints are reports submitted to NHTSA by owners and drivers. NHTSA does not verify most reports before publishing them, and a complaint does not establish that a defect exists. Volume is influenced by how many of a vehicle were sold, how long it has been on the road, and how much attention an issue has received.
0
Safety recallsA 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.

InvestigationsNHTSA 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.
0
Crash or fire reportedComplaints whose submitter recorded that a crash or a fire occurred. These are the reporter's own answers on the NHTSA form, not verified findings.

ELECTRONIC STABILITY CONTROL (ESC); SERVICE BRAKES, AIR:ANTILOCK

Dec 19, 2025
6,673 units potentially affected
The 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."
The 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.
The 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.
