Vehicles Affected: About 9,400 model-year 2007-2011 Chevrolet Silverado 2500/3500 and GMC Sierra 2500/3500 pickup trucks equipped with the auxiliary battery option
The Problem: The owner's manual for the recalled vehicles does not specify a maximum amperage rating for the auxiliary battery feed to a trailer harness. An electrical overload of the auxiliary battery feed may cause the underhood fusible link to melt and damage nearby wiring. GM is aware of six fires and 10 incidents of melting, all handled through warranty coverage.
The Fix: Dealers will inspect the affected vehicles, make the maximum amperage information available and replace any damaged parts for free.
What Owners Should Do: Contact your local Chevy or GMC dealer, or call Chevy at 866-694-6546 or GMC at 866-790-5700.
