Defect
Blue Bird Body Company (Blue Bird) is recalling certain 2020-2022 Vision and All American school buses. A retainer was not properly seated in the SC-3 single check valve and may not provide source air isolation when pressure is applied. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 121, "Air Brake System."
Safety risk
Unintended spring brake application may occur, increasing the risk of a crash.
Remedy
Dealers will replace the SC-3 check valves, free of charge. Owner notification letters were mailed on November 18, 2021. Owners may contact Blue Bird customer service at 1-478-822-2242. Blue Bird's number for this recall is R21BE-SB.
