Recall 14V186 affects 34 2008-2011 International 7400, M2, 4400, C5500, 4300, and F-750 vehicles for converter fire risk. Repair is free at an International dealer.
International is recalling 34 2008-2011 utility vehicles, including 4300, 4400, and 7400 trucks, because Sure Power DC-DC converters use epoxy insulation that can conduct electricity after heat exposure. Once conductive, the material can melt and burn, increasing the risk of a fire; the dealer repair will be free once International makes it available at a franchised dealer.

What's wrong?
The Sure Power DC-DC converter in these 2008-2011 International utility vehicles is part of the battery and electrical system. Its job is to take power from one electrical circuit and provide the correct direct-current voltage to another circuit. Inside the converter, an epoxy sealing material, also called potting compound, insulates electrical parts and helps keep moisture and vibration away.
In the affected converters, that potting compound does not stay electrically insulating after heat exposure. Once heated, the material can conduct electricity. That creates a path for current where the converter is supposed to keep circuits separated, so the converter no longer protects the electrical system the way it was designed to.
There is no warning sign before failure. An owner should not expect a dashboard light, sound, smell, or visible change to confirm that the converter has started to fail.
Who's affected?
Spans six medium-duty truck models across the 2008-2011 model years, all tied to the battery system.

| 2010 International 4400 | battery |
| 2008 GMC C5500 | battery |

The year and model narrow the scope, but the VIN decides. Check your VIN to confirm whether your specific truck is included.
What's the safety risk?
Electrically conductive material can melt and burn, increasing the risk of a fire. If your VIN is included, schedule service and avoid delaying the converter replacement. Repair will be free at any franchised International dealer once available.
What should I do?
- Check your VIN to confirm your 2008-2011 International 7400, M2, 4400, C5500, 4300, or F-750 is included in this recall.
- Use the owner notice mailed on May 29, 2014, or call International customer service at 1-800-558-4004 if you never received one.
- Reference recall number 14V186 when you call so the service desk can find the DC-DC converter recall.
- Ask about the free Sure Power DC-DC converter replacement, which fixes the heat-exposed potting compound that can conduct electricity and increase fire risk.
- Avoid adding electrical load or using aftermarket equipment tied to the affected converter until the repair is complete.
What happens at the repair
The repair calls for Sure Power to replace the DC to DC converters that use the heat sensitive potting compound. The record does not list a current remedy status, so confirm the open repair before arranging service. Once the repair is available for your VIN, the converter replacement is free under the recall. An International service desk can help route the vehicle through the correct repair process and confirm whether the supplier replacement is already open for your vehicle.

Frequently asked questions
What is recall 14V186?
Recall 14V186 covers 34 2008-2011 International 7400, M2, 4400, C5500, 4300, and F-750 vehicles with Sure Power DC-DC converters. The converter insulation compound can conduct electricity after heat exposure, then melt and burn, increasing the risk of a fire.
What should I do if my 2008-2011 International 7400, M2, 4400, C5500, 4300, or F-750 is on this recall?
Check your VIN to confirm your specific vehicle is included in recall 14V186. If it is, contact an International dealer or call DUECO at 1-800-558-4004 and ask for the free Sure Power DC-DC converter replacement.
Is the recall repair free?
Yes. DUECO's remedy states that Sure Power will replace the affected DC-DC converters free of charge. Federal recall law requires the recall repair to be performed at no cost to the owner when the vehicle is included.
What is the safety risk?
The safety risk is fire. The epoxy sealing compound inside the affected DC-DC converter can become electrically conductive after heat exposure. Once that happens, the material can melt and burn, increasing the risk of a vehicle fire.
What if I bought this vehicle used?
The free recall repair still applies. Recall coverage follows the vehicle, not the first owner. If you did not receive the 2014 owner notice, check your VIN and reference recall 14V186 when you contact the dealer or DUECO.
