2018 BLUE BIRD ALL AMERICAN

POWER TRAIN:DRIVELINE

Blue Bird Body Company (Blue Bird) is recalling certain 2018-2021 All American and Vision School Buses, equipped with PowerDrive 7000 electric drive systems. The System Control Module (SCM) may activate the anti-rollback feature, causing the vehicle to reverse faster than expected when the vehicle is in reverse and pointing downhill with the brake pedal not applied.

Risk: A vehicle reversing faster than expected can increase the risk of a crash.

STRUCTURE

Blue Bird Body Company (Blue Bird) is recalling certain 2014-2024 All American school buses equipped with 39" High Back seat restraining barriers. The bolts securing the restraining barriers to the floor may separate when fully loaded. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 222, "School Bus Passenger Seating and Crash Protection."

Risk: An unsecured seat restraining barrier may not properly restrain an occupant during a crash, increasing their risk of injury.

STEERING

Blue Bird Body Company (Blue Bird) is recalling certain 2018-2021 Vision and All American school buses. The drivetrain may experience an electromagnetic noise on the Control Area Network (CAN) bus, which may cause a loss of electrical power to the power steering pump.

Risk: A loss of assisted power steering increases the risk of a crash.

FUEL SYSTEM, DIESEL:FUEL INJECTION SYSTEM:FUEL RAIL

Blue Bird Body Company (Blue Bird) is recalling certain 2018-2022 All American vehicles. The sealing washer may not seat correctly in the pilot bore holes, allowing the high pressure fuel rail assembly to leak.

Risk: A fuel leak in the presence of an ignition source increases the risk of a fire.

FUEL SYSTEM, DIESEL:FUEL INJECTION SYSTEM:FUEL RAIL

Blue Bird Body Company (Blue Bird) is recalling certain 2018-2022 All American buses. The sealing washer may not seat correctly in the pilot bore holes, allowing the high pressure fuel rail assembly to leak.

Risk: A fuel leak in the presence of an ignition source increases the risk of a fire.

ELECTRICAL SYSTEM:SOFTWARE

Blue Bird Body Company (Blue Bird) is recalling certain 2018-2021 Vision and All American school buses. The electric drive train cannot detect isolation faults when the high voltage contactors are closed.

Risk: An undetected high voltage isolation can expose service personnel to high voltage, increasing the risk of injury.

SEAT BELTS:FRONT:ANCHORAGE

Blue Bird Body Company (Blue Bird) is recalling certain 2018-2021 All-American and 2019-2021 Vision school buses. The three-point seatbelt assembly may have been installed without reinforcing washers under the floor at the anchorage point, possibly preventing the assembly from remaining anchored in the event of a crash. As such, these vehicles fail to comply with Federal Motor Vehicle Safety Standard number 210, "Seat Belt Assembly Anchorages."

Risk: In the event of a crash, seat belt anchorages that do not remain secured increase the risk of injury to those seat occupants.

SEATS:BARRIERS

Blue Bird Body Company (Blue Bird) is recalling certain 2008-2021 Vision and All American school buses. The seat barrier behind the driver seat with an integrated 3-point seat belt may have been installed incorrectly and may be missing the reinforcing bracket. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 222, "School Bus Passenger Seating and Crash Protection."

Risk: In the event of a crash, the seat barrier may not adequately protect the occupant seated behind the seat barrier separating them from the driver seat with integrated 3-point seat belt, increasing the risk of injury.

POWER TRAIN

Blue Bird Body Company (Blue Bird) is recalling certain 2018-2019 Vision and All American school buses equipped with 7000 EV electric drivetrain units. A connector within the wire harnesses may become unplugged causing loss of communication between control modules, resulting in sudden loss of drive power and power steering.

Risk: A sudden loss of drive power and loss of power steering increases the risk of a crash.

SERVICE BRAKES, AIR:DISC

Blue Bird Body Company (Blue Bird) is recalling certain 2015-2020 Vision and All American school buses equipped with Bendix ADB22X air brakes. The driver side rear brakes may drag.

Risk: A dragging brake may cause damage to the brake components, which may activate the ABS warning light. The warning light may cause the driver to immediately stop the vehicle and transfer occupants. Additionally, the high temperatures at the wheel end can increase the risk of a fire. Either condition increases the risk of injury.

EQUIPMENT ADAPTIVE/MOBILITY

Blue Bird Body Company (Blue Bird) is recalling certain 2015-2019 Vision and All American school buses equipped with Ricon S-Series Titanium Wheelchair lifts. The wheelchair lift positioning input cam may fail while the lift is in use, allowing the platform to travel higher than the vehicle's floor height. As such, this vehicle fails to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 403, "Platform Lift Systems."

Risk: If the wheelchair lift platform raises above the height of the vehicle floor, the wheelchair user could fall inwards toward the vehicle, increasing their risk of injury.

HYBRID PROPULSION SYSTEM

Blue Bird Body Company (Blue Bird) is recalling certain 2018-2019 Vision and All American school buses equipped with PowerDrive 7000 EV electric drivetrains. The Vehicle Control Unit (VCU) may unexpectedly shut down the high voltage contactors, resulting in loss of all systems powered by high voltage, including the traction drive system and power steering.

Risk: An unexpected loss of drive and power steering may increase the risk of a crash.

POWER TRAIN:AUTOMATIC TRANSMISSION:CONTROL MODULE (TCM/PCM/TECM)

Blue Bird Body Company (Blue Bird) is recalling certain 2018-2019 Vision and All American school buses equipped with Cummins PowerDrive 7000 EV electric drivetrain units. Due to a software error, the VCU may activate the anti-roll back feature during slow moving or stop and go conditions, which can cause unexpected vehicle movement.

Risk: Unexpected vehicle movement can increase the risk of a crash.

SERVICE BRAKES, AIR:DISC:CALIPER

Blue Bird Body Company (Blue Bird) is recalling certain 2016-2020 Vision and 2015-2020 All American non-school buses equipped with ADB22X disc brakes. The driver side rear brakes may drag.

Risk: A dragging brake may cause damage to the brake components, which may activate the ABS warning light. The warning light may cause the driver to immediately stop the vehicle and transfer occupants. Additionally, the high temperatures at the wheel end can increasing the risk of a fire. Either condition increases the risk of injury.

STRUCTURE:EMERGENCY:ESCAPE/EGRESS/EXIT

Blue Bird Body Company (Blue Bird) is recalling certain 2018-2020 Vision and All American school buses equipped with Specialty Manufacturing Prolo roof emergency exit hatches. Due to a manufacturing issue, the roof hatch external handle may unexpectedly break under reasonable use. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 217, "Bus Emergency Exits and Window Retention and Release."

Risk: If the roof hatch external handle breaks, in the event of an emergency, the hatch cannot be easily opened from outside the vehicle, increasing the risk of injury.

EQUIPMENT

Blue Bird Body Company (Blue Bird) is recalling certain 2007-2019 Blue Bird All American ambulance buses. The clamps that secure the stacked stretchers may fail from repeated use or from high loads.

Risk: If the clamps fail with patients in the stretchers, it can increase the risk of injury.

SERVICE BRAKES, AIR

Blue Bird Body Company (Blue Bird) is recalling certain 2018-2019 Blue Bird All American and Vision school buses. The primary and secondary air brake gauges on the instrument cluster may intermittently indicate "0 PSI" instead of the correct air pressure in the tanks. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 121, "Air Brake Systems."

Risk: If the gauges do not correctly display the air pressure that is in the tanks, the operator will not be able to know when the air pressure is actually dropping, increasing the risk of a crash.
