GMC is recalling 9,371 2007-2011 Sierra 3500, Sierra 2500, Silverado 2500, and Silverado 3500 trucks equipped with an auxiliary battery because trailer-harness current can melt the auxiliary-battery fusible link.

What's wrong?
The auxiliary battery system on these 2007-2011 GMC Sierra 3500, Sierra 2500, Silverado 2500, and Silverado 3500 trucks supplies extra electrical capacity for equipment and trailer use. A trailer harness is the wiring connection that sends power from the truck to a trailer. A fusible link is a short protective wire that is designed to melt and open the circuit when current gets too high.
In affected trucks equipped with an auxiliary battery, the trailer harness can draw more current than the fusible link can safely carry. The owner does not have to make a mechanical mistake for this to happen. When the current load rises through that harness, the fusible link for the auxiliary battery can melt, damaging that part of the electrical path.
There is no warning sign before failure. The issue is tied to electrical load through the trailer connection, so an owner can notice the problem only after the fusible link has already melted.

The year and model narrow the scope, but the VIN decides. Check your VIN to confirm whether your specific pickup truck is included.
What's the safety risk?
A melted fusible link can touch nearby parts, damage the electrical center cover, wiring harness conduit, and other vehicle components, and increase the risk of a fire. If your VIN is included, schedule the recall repair soon and follow any dealer handling instructions. Repair will be free at any franchised GMC dealer once available.
What should I do?
- Check your VIN to confirm your 2007-2011 GMC Sierra 3500, Sierra 2500, Silverado 2500, or Silverado 3500 is included in this recall.
- Contact a franchised GMC dealer and ask whether the free jumper-harness repair is open for your VIN.
- Reference recall number 14V407 when you call, and ask the dealer to replace the trailer-harness jumper with the fused 40 amp inline harness that prevents auxiliary-battery overcurrent.
- Bring the recall notice if you have it, plus any owner manual supplement GMC sent with the recall.
- Avoid heavy auxiliary-battery trailer loads until the repair is complete, since too much current through the trailer harness can overheat the fusible link and raise fire risk.
What happens at the repair
When the dealer repair is available, a GMC technician replaces the auxiliary battery jumper harness with a new harness that includes a 40 amp inline fuse. The dealer also gives the owner supplemental Owner Manual information for the auxiliary battery and trailer harness setup. Parts and labor are covered under the recall. The source does not give a separate reimbursement plan, so ask the service desk only about the free recall repair described in campaign 14V407.
