  FUEL SYSTEM, GASOLINE:STORAGE:TANK ASSEMBLY

  General Motors, LLC (GM) is recalling certain 2016-2018 GMC Sierra 3500 and Chevrolet Silverado 3500 trucks equipped with gasoline engines and dual fuel tanks. The fuel-level sensor in the front tank may stick in a low-level position, allowing the rear tank to overfill the front tank.

  Risk: 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 module, inspect the front tank and, if necessary, replace the front tank, free of charge. The recall began July 30, 2019. GM's number for this recall is N182204190.
