NHTSA's recall notice

As NHTSA's recall record states it for campaign 23V424000.

Defect description

Blue Bird Body Company (Blue Bird) is recalling certain 2022-2024 All American transit buses. A software error in the instrument cluster may cause the air pressure gauges and the visual and audio low air warnings to not function. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 121, "Air Brake Systems."

Safety consequence

Air gauges and warnings that do not alert the driver to air pressure loss, can result in driving without functioning brakes, increasing the risk of a crash.

Manufacturer remedy

Dealers will update the instrument cluster software, free of charge. Owner notification letters were mailed July 27, 2023. Owners may contact Blue Bird's customer service at 1-478-822-2242. Blue Bird's number for this recall is R23CH (NSB).
