What's wrong?
The air dryer on 2016-2018 International Rh, Prostar, Lonestar, and Lt trucks removes moisture from the compressed-air system. That air system feeds the service brakes, so it has to hold pressure and route air through the brake lines without leaks. The mounting bracket is the steel support that keeps the air dryer fixed to the truck frame.
On affected trucks, that bracket was not strong enough for the load it carries. Over time, vibration and stress can fatigue the metal until the bracket cracks or breaks. If the air dryer separates from the frame, an airline can pull loose, creating an air leak or dropping pressure to the brake system.
The driver can see the warning before the brake system loses pressure. Watch the air-pressure gauge, and listen for the in-cab buzzer that sounds when air pressure drops.

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?
Brake air pressure loss lengthens stopping distance and increases crash risk. If an airline separates from the dryer while the truck is operating, the driver can see air pressure drop on the gauge or hear the cab buzzer. Treat either warning as a reason to pull over safely and arrange service. Repair is free at any franchised International dealer.
What should I do?
- Check your VIN to confirm your 2016-2018 International Rh, Prostar, Lonestar, or Lt is included in this recall.
- Contact a franchised International dealer to schedule the free air-dryer mounting-bracket replacement that fixes the bracket fracture tied to brake air pressure loss.
- Bring the recall notice if International mailed one. If not, reference recall number 17V174 when you call.
- Drive cautiously until the repair is complete. Avoid hard braking and leave extra following distance.
