Recall 11V590 affects 684 2012 International Prostar trucks because ESC can apply an outer front brake. Repair is free at any franchised International dealer.
International is recalling 684 2012 Prostar commercial trucks because the electronic stability control system can misread body roll and road angle, then apply an outer front brake. If the driver reacts slowly during that braking, the truck can leave its intended line of travel and increase crash risk; the International dealer repair will be free once available.

What's wrong?
The 2012 International Prostar uses an electronic stability control system, often called ESC, to help the truck stay on its intended path. The system watches body roll, road angle, wheel behavior, and steering inputs, then applies individual brakes when it detects a stability problem.
On trucks included in NHTSA campaign 11V590, certain road and driving conditions can distort the ESC calculation of slip angle, which is the difference between where the truck is pointed and where it is actually moving. The system can read that bad calculation as oversteer. When that happens, ESC applies the outer wheel brake on the front axle until the truck is read as stable again.
The defect is in how the ESC unit interprets road inclination and body roll, not in normal brake pedal operation. There is no warning sign before failure. The driver would notice the problem only when the system intervenes and applies that front brake unexpectedly.

Not every 2012 International Prostar truck is on the list. Check your VIN to confirm whether your specific truck is included.
What's the safety risk?
During an ESC intervention, a slow driver response can let the vehicle move away from its intended line of travel, increasing crash risk. Drive cautiously, leave extra following distance, and schedule service soon if your VIN is included. Repair will be free at any franchised International dealer once available.
What should I do?
- Check your VIN to confirm your 2012 International Prostar is included in this recall.
- Contact International customer service at 1-800-448-7825 if you never received the recall instructions tied to this VIN.
- Ask a franchised International dealer about the free ESC module installation that fixes the stability-control brake intervention issue.
- Bring the recall notice if you have it. If not, reference recall number 11V590 when you call.
- Drive cautiously until the repair is complete, and tell the dealer if the truck has pulled away from its intended line during ESC activation.
What happens at the repair
At the dealer, an International technician installs a new electronic stability control module. That module controls how the ESC system reads body roll, road angle, and wheel slip before applying brake force. The dealer repair will be free once available, with parts and labor covered under the recall. The filing does not list a repair time, so ask the service desk how long the module installation is scheduled to take.
