GM recalling 2011-2015 Chevy Silverado 3500, GMC Sierra 3500 over fuel tank issue

The 24.5 gallon CNG tank, located directly behind the cab, in addition to the 23.5 gallon gasoline tank on the Silverado 3500HD gives drivers fueling flexibility and optimal range between fill-ups.

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.
