The defect

General Motors LLC (GM) is recalling certain model year 2007-2011 Chevrolet Silverado HD 2500/3500 trucks manufactured January 18, 2007, to June 22, 2011, and GMC Sierra HD 2500/3500 trucks manufactured January 22, 2007, to June 21, 2011, and equipped with an auxiliary battery. Owners may unknowingly draw too much current through the vehicle's trailer harness resulting in the melting of fusible link for the auxiliary battery.

The risk

If the fusible link melts it may come into contact with adjacent components, damage the electrical center cover, the nearby wiring harness conduit and other vehicle components, increasing the risk of a fire.

The fix — what to do

GM will notify owners and dealers will replace the jumper harness with one that includes a 40 amp inline fuse, and provide the owner with supplemental Owner Manual information, free of charge. The recall began on August 29, 2014. Owners may contact Chevrolet customer service at 1-800-222-1020 or GMC customer service at 1-800-462-8782. GM's number for this recall is 14260.
