What's wrong?
The headlight software on the 2025 Ic Bus Cecb controls how the halogen headlamps switch between low beam and high beam. Low beams light the road close to the bus and help control glare for other traffic. High beams add farther-ahead lighting for dark roads, while the low beams are supposed to stay on as required by FMVSS 108.
On affected buses, the vehicle was built without the correct software for that lighting behavior. When the driver turns on the high beams, the low beams turn off instead of staying lit. That leaves the driver with less near-field light directly in front of the bus and creates a lighting setup that does not comply with the federal headlamp standard.
The warning sign is visible from the driver's seat. When the high beams are on, objects that were visible with the low beams no longer appear clearly in the light pattern.

Not every 2025 Ic Bus Cecb bus is on the list. Check your VIN to confirm whether your specific bus is included.
What's the safety risk?
Headlight low beam failure can reduce visibility and increase the risk of a crash. When high beams are activated, objects visible with low beams can disappear from view. If that happens, slow down, use caution, and schedule the software update. Repair is free at any franchised Ic Bus dealer.
What should I do?
- Check your VIN to confirm your 2025 Ic Bus Cecb is included in this recall.
- Contact a franchised Ic Bus dealer to schedule the free BCM software update that keeps the low beams on when high beams are activated.
- Bring the recall notice if Ic Bus mailed one. If not, reference recall number 25V177 when you call.
- Drive with care until the repair is complete, especially at night or in low-visibility conditions.
What happens at the repair
At the dealer, an Ic Bus technician updates the body control module (BCM) software so the headlight logic keeps the low beams on when high beams are selected. The update is available now, and the software work is free under recall 25V177. If you already paid for a related repair before the recall notice, International's reimbursement plan applies. Use the instructions in the owner letter and bring documentation for the service desk to review.
