What's wrong?
The brake lights on the 2024-2025 Ic Bus Ce Sbus and Cesb school buses are controlled through software tied into the air brake pressure monitoring system. In normal operation, pressing the brake pedal changes air pressure in the brake circuits, and the software reads that signal so the rear stop lamps turn on. Those lamps tell traffic behind the bus that the driver is slowing or stopping.
On affected buses, the software was built with the wrong configuration for the installed air brake pressure monitoring hardware. If pressure is completely drained from one air brake circuit while pressure remains in the other, the software does not read the brake pedal signal correctly. The brakes can still be applied, but the stop lamps do not illuminate when the driver presses the pedal in that condition.
There is no warning sign before failure. The driver has no separate alert that the brake lights stayed off while braking.
Who's affected?
Covers two school bus models from the 2024 and 2025 model years, both tied to brake light software.
| 2024 Ic Bus Ce Sbus | Brake lights |

| Units affected | 319 |
| Field incidents | NHTSA has logged no field incidents to date. |
The year and model narrow the scope, but the VIN decides. Check your VIN to confirm whether your specific bus is included.
What's the safety risk?
Brake lights that fail to illuminate make the bus harder to see and fail to tell other drivers that the bus is slowing, increasing crash risk. There is no warning sign before the brake lights fail, so schedule the software update soon and use extra care around following traffic. Repair is free at any franchised Ic Bus dealer.
What should I do?
- Check your VIN to confirm your 2024-2025 Ic Bus Ce Sbus or Cesb is included in this recall.
- Contact a franchised Ic Bus dealer to schedule the free software update that fixes the brake-light illumination failure.
- Bring the owner letter if you have it, and reference recall number 24V375 and Ic Bus recall 24508 when you call.
- Verify the brake lights before service, and keep the bus out of route service if the brake lights fail to illuminate.
- Call Ic Bus customer service at 1-800-448-7825 with questions about the recall or dealer scheduling.
What happens at the repair
