Chevrolet is recalling 2015 Silverado 3500 trucks with a fuel system issue that could cause tank overfill, leading to potential fire risks. Owners should contact GM for free repairs.

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.
