2016 Nova Bus Lfs Artic Recall

On certain vehicles, the recall repairs completed during Transport Canada recalls 2017-477 and 2018-062 may not have been done correctly. As a result, another repair is required. On certain transit buses, the coolant hoses for the heating system installed inside the roof could fail. As a result, coolant could leak into the bus.

A coolant leak could create the risk of a burn injury.

Nova Bus will notify owners by mail and provide you with instructions for how to inspect and, if necessary, replace the coolant hoses for the roof unit.

This recall is for brake chambers installed on certain transit buses or sold as a replacement part. On certain transit buses, the brake chamber(s) on the rear axle may be defective. As a result, air could leak from the chamber and cause the parking brake to apply while driving without the brake lights turning on. If this happens, the brakes could overheat.

A parking brake that self-applies while driving without the brake lights turning on could cause a person not to recognize that the vehicle is braking. This could increase the risk of a crash. Additionally, overheated brakes could create the risk of a fire.

Nova Bus will notify owners by mail and provide you with instructions for how to inspect and, if necessary, replace the brake chamber(s).

On certain buses, the convex passenger-side exterior rearview mirror may not be curved enough. If fitted with a convex passenger-side mirror, Canadian regulations require a minimum and maximum curvature radius of the mirror surface.

This small error does not affect safety, as the visibility out of the vehicle is not limited by the non-compliant mirror assembly.

This is not a recall. Nova Bus has made production changes to ensure that all new buses have compliant convex passenger-side rear-view mirrors.

On certain hybrid buses, a speed sensor fault could cause a loss of power steering assist.

A loss of power steering assist would result in a sudden increase in steering effort, especially at low speeds. This could increase the risk of a crash.

Nova Bus will notify owners by mail and provide them with instructions for updating the hybrid system software. This update will allow the power steering assist to remain active until the vehicle is stopped.

On certain transit buses, the stop lamps and tail lamps are located too high above the ground. Canadian regulations provide a maximum mounting height for the stop lamps and tail lamps.

Stop lamps and tail lamps that are mounted too high may cause reduced visibility, which could increase the risk of a crash.

Nova Bus will notify owners by mail and provide them with directions for changing the mounting position of the stop and tail lamps.

On certain transit buses, the hardware used to secure some of the seats was not properly tightened. This could cause the hardware or seat mount to fail. As a result, the seat could drop to the floor.

Seats that are not secure could create a risk of injury for passengers.

Nova Bus will notify owners in writing and provide them with directions for inspecting and replacing the seat rails and hardware.

On certain buses, the electrical connector for the engine door fan is too small and could overheat.

An electrical connector that overheats could create the risk of a fire.

The company will notify owners by mail. Owners will be supplied with parts and instructions for replacing the electrical connector for the engine door fan.

On certain articulated transit buses equipped with a Hubner turntable and Cummins engine, an engine fault code may cause the articulating dampener control unit to misinterpret the vehicle’s speed. This would result in no dampening in the articulation, which would reduce vehicle stability and increase the risk of a crash causing injury and/or damage to property. Correction: The articulating dampener control unit software will be updated to alert the driver in the case of an engine fault and put the vehicle into emergency mode if vehicle speed cannot be interpreted.

A failure of this component (suspension) may increase the risk of a crash or injury.

Authorized dealerships will inspect the vehicle and complete all necessary repairs free of charge (parts and labor).

On certain replacement seat belts sold through Prevost’s Part and Service Center for use on Recaro AM72 or AM80 driver seats, the buckle assembly of the driver’s seat belt may be defective. This may result in an inability to insert the seat belt tongue into the buckle assembly. In the event of a crash, an unbuckled seat belt may increase the risk of injury to the driver. Correction: Owners will be contacted by Nova Bus and supplied with the inspection and repair instructions. Replacement driver seat belts and hardware will be provided by Nova Bus as required.

A failure of this component (seats and restraints) may increase the risk of a crash or injury.

Authorized dealerships will inspect the vehicle and complete all necessary repairs free of charge (parts and labor).

On certain buses, there may be increased friction in a brake caliper guide pin due to a manufacturing defect. If undetected, this could cause the breakage of the guide pin bolt, irregular brake pad wear, and brake pad contact with the surface of the wheel. This could result in the sudden loss of tire pressure or brake function and possibly reduced parking brake functionality, increasing the risk of a crash causing injury and/or property damage. Correction: New guide pins will be installed at each wheel end on suspect axles.

A failure of this component (brakes) may increase the risk of a crash or injury.

Authorized dealerships will inspect the vehicle and complete all necessary repairs free of charge (parts and labor).

On certain vehicles, PEX connectors in the passenger compartment heating system may have been exposed to lubricant at time of assembly and/or if the transmission oil cooler were to fail, could be contaminated with transmission oil. This could cause the connection to degrade, potentially resulting in a leak. Leaking coolant could come into contact with passengers, resulting in burn injuries. Correction: Connectors will be replaced. Note: This is an expansion of recall 2017-477.

A failure of this component (heater and defroster) may increase the risk of a crash or injury.

Certain buses could experience a loss of communication within the bus multiplex network. This could cause the engine to accelerate to full RPM without throttle input by the driver, which could increase the risk of a crash causing injury and/or damage to property. Correction: Nova Bus will reprogram the vehicles to correct this issue.

On certain vehicles, the pin that attaches to the windshield wiper idler arm could strip. If the pin were to become stripped, it would result in the driver side windshield wiper to become inoperable. Loss of windshield wiping capability, should it occur during a rainy/snowy day, may compromise the driver's ability to see the road and its users, which could result in a crash causing property damage and/or injury. Correction: Dealers will replace the the suspect idler arm of the windshield wiper assembly.

A failure of this component (visual system) may increase the risk of a crash or injury.
