NOVA BUS LFS

ELECTRICAL SYSTEM:PROPULSION SYSTEM:TRACTION BATTERY

Nova Bus (US) Inc. (Nova Bus) is recalling certain 2022-2023 Nova Bus LFS transit buses. The high voltage batteries may have loose hardware that can fall inside the battery pack and create a short circuit.

Risk: A short circuit increases the risk of a fire.

STRUCTURE:EMERGENCY:ESCAPE/EGRESS/EXIT

Nova Bus (US) Inc. (Nova Bus) is recalling certain 2006-2007 LFS transit buses. The buses may have been built with an incorrect number of emergency exits. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 217, "Bus Emergency Exits and Window Retention and Release."

Risk: An insufficient number of emergency exits can prevent or delay passengers from exiting during an emergency, increasing their risk of injury.

EXTERIOR LIGHTING:TURN SIGNAL

Nova Bus (US) Inc. (Nova Bus) is recalling certain 2022-2023 LFS buses. A digital display firmware error may cause the instrument panel indicator lights to remain solidly illuminated even when the turn signal are off. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 108, "Lamps, Reflective Devices, and Associated Equipment."

Risk: A faulty indictor light, that cannot provide the driver with information about the status of the turn signals, increases the risk of a crash.

STEERING:ELECTRIC POWER ASSIST SYSTEM

Nova Bus (US) Inc. (Nova Bus) is recalling certain 2020-2023 LFS transit buses. The electric power steering system may be missing a check valve, allowing hydraulic pressure to turn the steering wheel without the driver's input.

Risk: A steering wheel that turns unintentionally increases the risk of a crash or injury.

ENGINE AND ENGINE COOLING:COOLING SYSTEM

Nova Bus (US) Inc. (Nova Bus) is recalling certain 2013 LFS transit buses. The coolant hoses routed through the HVAC roof unit may fail and leak coolant into the passenger seating area.

Risk: Hot coolant that leaks into the passenger seating area increases the risk of injury.

ELECTRICAL SYSTEM:WIRING

Nova Bus (US) Inc. (Nova Bus) is recalling certain 2022-2023 LFS transit buses. The engine wiring harness may be the incorrect length, which can result in harness damage and a loss of drive power.

Risk: A loss of drive power can increase the risk of a crash.

VISIBILITY:DEFROSTER/DEFOGGER/HVAC SYSTEM:WINDSHIELD:ELECTRICAL HEATING ELEMENT

Nova Bus (US) Inc. (Nova Bus) is recalling certain 2019-2024 LFS and 2019-2023 LFS Artic buses. The auxiliary heater module may allow contaminants to enter the electronic controller, which can cause an electrical short. Additionally, the auxiliary heater may fail, causing the defrosting system to not function properly.

Risk: An electrical short circuit can increase the risk of a fire. Additionally, a windshield defrosting system that does not function properly can decrease the driver's visibility, increasing the risk of a crash.

PARKING BRAKE:CONVENTIONAL:AIR

Nova Bus (US) Inc. (Nova Bus) is recalling certain 2021-2024 LFS and 2021-2023 LFS Artic buses. An air leak may occur in the parking brake valve and unintentionally engage the parking brake without activating the brake lights.

Risk: A bus that stops suddenly without activating brake lights increases the risk of a crash.

ELECTRICAL SYSTEM

Nova Bus (US) Inc. (Nova Bus) is recalling certain 2022-2023 LFS buses. The ground connection on the bus bar in the HVAC roof unit may not be secured properly, which can result in an unexpected engine shutdown or an overheated ground connection.

Risk: An unexpected engine shutdown increases the risk of a crash. An overheated ground connection can increase the risk of a fire.
