International recall 10V037 covers 1,437 2009-2010 Lonestar and Prostar trucks with roll stability control air lines connected to the wrong air-tank port.

What's wrong?
The roll stability control system on 2009-2010 International Lonestar and Prostar trucks is designed to help manage a trailer during a potential roll event. It uses air pressure and control valves to modulate the trailer brakes when the system detects that extra stability help is needed. The driver's regular tractor and trailer service brakes still work through their normal brake controls.
On trucks equipped with the specified roll stability control setup, the air line that feeds the traction solenoid valve was connected to the wrong port on the air tank. That wrong connection changes how air reaches the trailer brake control circuit when roll stability control activates. During a roll stability event, trailer brake modulation from the stability system does not happen as designed, although the normal driver-applied service brakes and the tractor's own roll stability function are not affected.
There is no warning sign before failure. The issue appears only when the roll stability control system activates during a roll stability event, so a driver should not expect a light, noise, or brake-pedal change during normal braking.
Who's affected?
Covers Lonestar and Prostar trucks from the 2009 and 2010 model years, all tied to electronic stability control.

A matching year and model does not guarantee inclusion. Check your VIN to confirm whether this recall applies to your specific truck.
What's the safety risk?
During a roll stability event, reduced RSC control of the trailer brakes increases crash risk, with property damage, personal injury, or death as the stated consequence. If your VIN is included, schedule the air line inspection and relocation through the dealer and drive with added caution until the work is complete. Repair will be free at any franchised International dealer once available.
What should I do?
- Check your VIN to confirm your 2009-2010 International Lonestar or Prostar is included in this recall.
- Contact a franchised International dealer to ask for the free air-line inspection and relocation that restores proper roll-stability control of the trailer brakes.
- Reference recall number 10V037 when you call the dealer or International customer service.
- Bring the recall notice if you have it, plus any service paperwork for the truck.
- Drive with extra space and caution until the repair is complete, especially when towing.
What happens at the repair
International's remedy calls for an International technician to inspect the air line that supplies the RSC traction solenoid valve and move it to the correct port on the air tank. That routing matters because the RSC system uses that air path to modulate trailer braking during a roll stability event. The dealer repair will be free once available, with parts and labor covered under the recall.

Frequently asked questions
What is recall 10V037?
Recall 10V037 covers 1,437 2009-2010 International Lonestar and Prostar trucks equipped with feature code 04AZT roll stability control. The traction solenoid valve air line was connected to the wrong air tank port, affecting trailer-brake modulation during a roll stability event.
What should I do if my 2009-2010 International Lonestar or Prostar is on this recall?
Check your VIN to confirm your specific truck is included in recall 10V037. If it is, contact a franchised International dealer to schedule inspection and air-line relocation. Reference recall number 10V037 when you call. The dealer repair is free.
Does the recall repair cost anything?
No. Federal recall law requires manufacturers to repair safety defects at no cost, and International dealers will inspect and relocate the RSC traction solenoid valve air line free of charge. Parts and labor are covered for included vehicles.
What is the safety risk in recall 10V037?
The risk is reduced trailer-brake control during a roll stability event. NHTSA campaign 10V037 describes less than optimal RSC control of the trailer brakes, with increased crash risk that includes property damage, personal injury, or death.
What if I bought my International truck used?
The free repair still applies. Recall coverage follows the truck, not the first owner. Check your VIN to confirm whether your specific Lonestar or Prostar is included, then call a franchised International dealer and reference recall number 10V037.
