2016 NOVA BUS LFS ARTIC

SEAT BELTS:FRONT

Nova Bus (US) Inc. (Nova) is recalling certain 2010-2020 LFS Artic and 2012-2024 LFS vehicles. The driver's seat belt may not retract properly. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 209, "Seat Belt Assemblies."

Risk: A seat belt that does not retract properly may result in a loose seat belt, which can increase the risk of injury in a crash.

SERVICE BRAKES, AIR:DISC:CHAMBER

Nova Bus (US) Inc. (Nova Bus) is recalling certain 2016-2019 LFS and LFS Artic buses. The brake chamber on the rear axle may have been improperly manufactured, which can result in an air leak.

Risk: A brake chamber air leak may cause the brakes to engage unexpectedly, which can overheat the brakes and increase the risk of a fire. Additionally, unexpected braking can increase the risk of a crash.

SEATS:CRITICAL FASTENERS

Nova Bus (US) Inc. (Nova) is recalling certain 2015-2019 LFS and LFS Artic transit buses. The attachment hardware may have been incorrectly installed beneath the rear wheel well passenger seats, allowing the seat to detach from the frame.

Risk: A detached passenger seat may inadequately restrain a passenger during a crash, increasing the risk of injury.

EXTERIOR LIGHTING

Nova Bus (US) Inc. (Nova) is recalling certain 2016-2020 LFS and 2013-2022 LFS Artic buses. The momentary STOP and YIELD text message board is duplicating the stop light and turn signal light signals. As such, these vehicles fail to comply with the requirements of the Federal Motor Vehicle Safety Standard number 108, "Lamps, Reflective Devices, and Associated Equipment."

Risk: The momentary text message board duplicating light signals may cause confusion, increasing the risk of a crash.

FUEL SYSTEM, DIESEL:FUEL INJECTION SYSTEM:FUEL RAIL

Nova Bus is recalling certain 2016-2020 LFS and LFS Artic 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.

POWER TRAIN:AUTOMATIC TRANSMISSION

Nova Bus (Nova) is recalling certain 2016 LFS and LFS Artic buses equipped with specific Allison Transmission drive units. The pressure switches on these Drive Units may fail, possibly resulting in a loss of drive.

Risk: A loss of drive can disable the vehicle unexpectedly, increasing the risk of a crash. Additionally, offloading passengers to transfer them to another bus can increase the risk of injury.

SEATS

Nova Bus (Nova) is recalling certain 2014-2017 LFS and LFS Artic buses equipped with USSC cantilever seats. The hardware used to attach the cantilever seats to the side rail may have been improperly tightened. As a result, the cantilever seat may drop to the floor.

Risk: If the cantilever seat drops while it is occupied, there is an increased risk of an injury.

ELECTRICAL SYSTEM:SOFTWARE

Nova Bus (Nova) is recalling certain 2013-2018 Nova LFS Artic transit buses. A fault code in the engine may cause the vehicle to operate at zero velocity and lack of dampening reducing vehicle stability.

Risk: If there is a loss of vehicle stability, it can increase the risk of a crash.

SERVICE BRAKES, AIR:DISC:CALIPER

Nova Bus (Nova) is recalling certain 2015-2017 Nova LFS and LFS Artic transit buses, equipped with axles with radial air disk brakes. Surface roughness of a guide pin in the radial brake calipers may cause the brake carriage guide pin support bolt to break.

Risk: Breakage of the guide pin can cause loss of braking ability or loss of tire pressure, increasing the risk of a crash.

ELECTRICAL SYSTEM

Nova Bus (Nova) is recalling certain 2016 Nova LFS Artic transit buses. In the event of a loss of communication within the bus' multiplex network, the computer may command full throttle application, without input from the driver.

Risk: Unintentional, full throttle application may increase the risk of a crash.
