Blue Bird Body Company (Blue Bird) is recalling certain 2023 Vision school buses equipped with an Allison transmission. The starter interlock settings in the vehicle software are incorrect, allowing the engine to crank while the T-handle gear shifter is in Reverse or Drive. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 102, “Transmission Shift Lever Sequence/Starter Interlock/Transmission Braking Effect.”
