SAINT-JEROME, Qué. — Lion Electric Company has agreed to recall certain model-year 2020-2022 LionC hybrid-electric school buses whose parking brakes may not function properly.
The 39 buses within the recall population may have inadequately adjusted parking brakes which would put them in violation of federal motor vehicle safety standard 105.
According to the National Highway Traffic Safety Administration (NHTSA) Part 573 Safety Recall Report 22V-530, “To meet this requirement, two main criteria must be met. The cable tension must be sufficiently high, and the cable sheath spring must operate freely to provide a constant parking brake force in both forward and reverse directions.”
The report did go on to state, “The identified failure of the parking brake may result in a crash, which is assessed as “unlikely”. The driver could be inside the vehicle and will therefore be able to apply the brakes if the vehicle begins to move. Also, the vehicle is more likely to move when fully loaded and parked on a high grade, which is not a common operational situation.”
The parking-brake cable route was changed during production producing the issue. It has since been modified to rectify the problem in production.
