The defect
Blue Bird Body Company (Blue Bird) is recalling certain 2017-2018 Blue Bird Vision transit buses equipped with Gen4 Ford engines with an optional brake and throttle interlock. The brake and throttle interlock is supposed to apply the service brakes and prevent accelerator pedal input when activated, however the throttle input is not being blocked.
The risk
If throttle input is allowed, the bus may be able to overpower the applied brake, causing the bus to move unexpectedly, increasing the risk of a crash or an injury.
