What's wrong?
The 2011 International 4300 uses fuel lines to carry fuel to the MaxxForce 7 engine. It also has a transmission electrical harness, a bundled set of wires that carries power and signals for transmission operation. Both parts are supposed to be routed with enough clearance from hot exhaust components, especially the turbo exhaust pipe.
On recalled trucks, the fuel lines and the harness were routed too close to that turbo exhaust pipe. The turbo exhaust pipe gets extremely hot during operation, so nearby lines and wiring lose their safety margin. Fuel line heat damage can let fuel leak onto the turbo pipe. Harness heat damage can melt insulation and lead to burning wires.
There is no warning sign before failure. A driver should not count on a light, smell, or drivability change before the fuel line leaks or the harness overheats.

What's the safety risk?
Fuel leaking onto the turbo exhaust pipe or a melting electrical harness can start a vehicle fire, with risk of property damage, injury, or death. Schedule the recall repair soon and keep the truck out of service if you see fuel or burning. Repair will be free at any franchised International dealer once available.
What should I do?
- Check your VIN to confirm your 2011 International 4300 is included in this recall.
- Contact a franchised International dealer to ask whether the free fuel-line and electrical-harness routing repair is open for your truck.
- Reference recall number 10V631 when you call, and ask the dealer to confirm that the fuel lines and wiring are routed away from the turbo exhaust pipe.
- Bring the owner notice if you have it. If not, bring your registration so the dealer can match the VIN.
- Avoid driving with any fuel smell, visible fuel leak, smoke, or burned-wiring odor before the repair.
What happens at the repair
For recall 10V631, the dealer repair path is a free inspection and correction of the fuel line and transmission electrical harness routing near the engine turbo exhaust pipe. An International technician should move or secure those parts so the fuel line and harness are no longer too close to the turbo exhaust area. The remedy text does not give a current scheduling status or a repair time, but it states that the dealer repair is free.
