NHTSA campaign 18V259000
Hazard
Blue Bird Body Company (Blue Bird) is recalling certain 2017-2018 Blue Bird Vision school 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.
Consequence
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.
Remedy
Blue Bird will notify owners, and dealers will update the Smart Relay Module software. The recall began on May 24, 2018. Owners may contact Blue Bird customer service at 1-478-822-2242. Blue Bird's number for this recall is R18ZF - SB.
