What's wrong?
The 2024-2025 Lion Lionc school buses in this recall use a full-air brake system. The anti-lock brake system, or ABS, helps keep the wheels from locking during hard braking. It reads wheel speed sensors and uses air-operated valves to adjust brake pressure at the wheels.
On affected buses, assembly errors left ABS pneumatic valve connections and rear wheel speed sensor connections installed in the wrong positions. That means the ABS receives the wrong signal or sends brake-pressure changes to the wrong place. In a hard stop, the rear wheels can lock instead of being controlled by the ABS. This is the defect described in NHTSA campaign 23V710.
There is no warning sign before failure. A driver should not expect a dashboard light, pedal change, or other advance notice that the ABS connections are wrong.
Who's affected?
Both model years use the same full-air brake harness option tied to the brake system.

What's the safety risk?
During ABS braking, incorrectly installed ABS valves and wheel speed sensors can cause a wheel to lock or cause loss of vehicle control, increasing crash risk. There is no warning sign before failure, so schedule the dealer repair soon and drive cautiously under hard braking. Repair is free at any franchised Lion dealer.
