What's wrong?
The Hill Start Assist valve is part of the air brake system on affected International Lt and Rh trucks. Hill Start Assist holds the service brakes briefly during a hill start so the truck does not roll while the driver moves from the brake to the throttle. The valve's exhaust port lets air pressure vent when the system releases the brakes.
The failure point is that exhaust port. If it becomes clogged, air pressure does not leave the valve at the intended rate. The service brakes then release late or do not release when commanded, leaving the truck held by the brakes after Hill Start Assist is supposed to let it move.
There is no warning sign before failure. Once the problem happens, the driver can feel the truck stay held after releasing the brake pedal, or the truck can resist moving when throttle is applied.

A matching year and model does not guarantee inclusion. Check your VIN to confirm whether your specific truck is included.
What's the safety risk?
If the brakes remain engaged while the truck is moving, stopping and handling can change and crash risk increases. Schedule the recall repair when International makes it available, and ask the dealer how to move the truck if the brakes feel stuck or do not release. Repair will be free at any franchised International dealer once available.
What should I do?
- Check your VIN to confirm your 2023-2026 International Rh or Lt truck is included in this recall.
- Wait for International's repair instructions before scheduling dealer work, because the remedy is listed as under development.
- Contact International customer service at 1-800-448-7825 to ask when the free HSA valve exhaust relocation opens for your VIN.
- Reference recall number 25V781 when you call International or a franchised International dealer.
- Drive with caution until the repair is complete, because the clogged HSA exhaust port can delay or prevent service-brake release.
What happens at the repair
International has not opened the final dealer repair yet. Once it is available, an International technician will relocate the Hill Start Assist valve exhaust so the exhaust port is less exposed to clogging that can delay or prevent service brake release. The recall repair will be free, with parts and labor covered. International uses its general reimbursement plan for eligible out-of-pocket repairs already paid before the recall notice. Keep repair invoices and payment records, then ask International customer service or the dealer service desk how to submit documentation.
