The defect
Lion Electric Company (Lion) is recalling certain 2019-2025 LionC hybrid electric school buses. The surge tank may move and crack the firewall, allowing the tank to contact and damage the high-voltage cables.
The risk
Damaged high-voltage cables can shut down the high-voltage circuit, causing a loss of steering assistance or drive power and reducing braking power, increasing the risk of a crash.
