What's wrong?
The air dryer discharge line on 2025-2026 Ic Bus Cecb buses is a nylon air line connected to the air brake system. The air dryer removes moisture from compressed air, and the discharge line routes air away from the dryer so the system maintains the pressure needed for braking and parking brake release.
On affected buses, the right passenger-side tire can rub that line during a full right turn. The line was routed without the needed clipping points, so tire contact can wear or damage it near the right fender. Once the line leaks, the air system loses pressure, and the parking brake can apply without the driver intending it.
Drivers or maintenance staff can see low air pressure warnings on the gauge cluster, hear low air system pressure alarms, or hear an air leak from the right passenger-side fender area. Those signs mean the air line needs inspection before the bus stays in service.

What's the safety risk?
Unintended parking brake activation while driving raises the risk of a crash. Treat low air system pressure alarms, pressure changes on the gauge cluster, or an audible air leak near the right passenger-side fender as a reason to stop in a safe place and call the dealer. Repair will be free at any franchised Ic Bus dealer once available.
What should I do?
- Check your VIN to confirm your 2025-2026 Ic Bus Cecb is included in this recall.
- Watch for International's repair instructions for your VIN before booking the final repair.
- Contact a franchised Ic Bus dealer to ask about the free air-line inspection for recall number 25V647.
- Bring the owner letter if International mailed one, and reference recall number 25V647 when you call.
- Drive cautiously until the repair is complete. Stop in a safe place if the parking brake activates while driving.
What happens at the repair
The final dealer repair is still under development. Once it opens, the Ic Bus dealer will inspect the air dryer discharge line, replace damaged lines, and reroute the lines so the tire no longer contacts them. Parts and labor are covered under the recall. Owner letters were mailed November 17, 2025. If you already paid for this line repair before the recall notice, contact International customer service at 1-800-448-7825 or ask the service desk about the manufacturer's standard reimbursement plan and bring repair documentation.
