NHTSA campaign 23V448, reported June 27, 2023, 133 vehicles potentially affected.

What this recall means for you

A surge tank in these hybrid electric school buses may move and crack the firewall. If that happens, the tank can contact and damage the high-voltage cables.

Damaged high-voltage cables can shut down the high-voltage circuit. This can cause a loss of steering assistance or drive power and reduced braking power, which increases the risk of a crash.

The repair is free. Lion technicians will install a new surge tank support bracket to the accessory plate at no charge. Owners can contact Lion customer service at 1-855-546-6706. You can also check your vehicle's VIN for open recalls.
