Problem Blue Bird Body Company (Blue Bird) is recalling certain 2020 Blue Bird All American and 2019-2020 Blue Bird Vision school buses, equipped with certain HSM NextGen 45" 3PT school bus seats, part number GenQ3-45 LH. There may be an insufficient number of bolts attaching the seat to the bus floor, allowing the seat to detach from the bus floor in the event of a crash. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 210, "Seat Belt Assembly Anchorages." Risk In the event of a crash, if the bus seat detaches from the floor, it can increase the risk of injury. Fix Blue Bird will notify owners, and dealers will install a secondary floor mounting brace, free of charge. The recall began December 12, 2018. Owners may contact Blue Bird customer service at 1-478-822-2242. Blue Bird's number for this recall is R18ZT-SB.

Two numbers, one recall

Every safety recall carries two identifiers. R18ZT-SB is the number Blue Bird assigned in its own system: it is what appears on the owner letter, on the dealer’s service screen and on the repair order. 18V846000 is the number NHTSA filed the same recall under when the manufacturer reported it, and it is the one every federal record, this site included, is keyed on.

The repair is free by federal law for vehicles up to fifteen years old. Whether one particular vehicle is included is settled by its VIN against the manufacturer’s build list, not by its model year.

Check one specific vehicle

Both lookups check a VIN against the manufacturer’s own list and say whether the repair is still outstanding on that vehicle.
