NHTSA Campaign 17V664000

FUEL SYSTEM, GASOLINE:STORAGE:AUXILLARY TANK

Issued by General Motors LLC · Reported Oct 19, 2017 · 35,292 vehicles affected

What's wrong

General Motors LLC (GM) is recalling certain 2011-2015 Chevrolet Silverado 3500 and GMC Sierra 3500 trucks equipped with dual fuel tanks. The low fuel level sensor for the front tank may stick causing the rear tank to overfill the front tank.

Consequence

If the front tank overfills, the excess pressure may cause the front tank to expand and contact the driveshaft, possibly resulting in a hole in the tank. The hole will leak fuel, which in the presence of an ignition source, can increase the risk of a fire.

Remedy

GM has notified owners, and dealers will replace the rear tank fuel pump or update the fuel-level sensor software, as well as inspect the front tank, replacing it as necessary, free of charge. The recall began December 11, 2017. Owners may contact GM customer service for Chevrolet 1-800-222-1020 or for GMC customer service at 1-800-462-8782. GM's number for this recall is 17399.
