Plain-English summary

New Flyer of America, Inc. is recalling certain 2021 model year XD35 and XD40 vehicles equipped with Cummins L9 Diesel Engines. The recall involves 28 affected vehicles.

The defect involves the engine calibration software, which may manage the injection of Diesel Exhaust Fluid in a way that allows excessive ammonia to be emitted from the tailpipe exhaust. Exposure to high levels of ammonia can increase the risk of injury.

Cummins will recalibrate the engine free of charge to correct the issue. Owner notification letters were mailed on July 23, 2021. Owners may contact New Flyer's customer service at 1-800-204-224-6706 or the NHTSA Vehicle Safety Hotline at 1-888-327-4236.
