Front Fuel Tank May Overfill and Cause Fuel Leak
Fuel system, gasoline · storage · auxillary tank
Official NHTSA text
- Summary
- 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.

Official NHTSA text
- Summary
- General Motors LLC (GM) is recalling certain model year 2014-2016 Buick Lacrosse and Chevrolet Spark EV, Caprice PPV and SS vehicles, 2014-2017 Buick Encore and Chevrolet Corvette, Silverado 1500 and GMC Sierra 1500 vehicles, 2015-2016 Cadillac Escalade and Escalade ESV, Chevrolet Tahoe, Trax, Suburban and Silverado 2500 and 3500 and GMC Yukon and Yukon XL vehicles, and 2015-2017 GMC Sierra HD 2500 and 3500 vehicles. While being previously remedied for recall 16V-651, the affected vehicles may not have received the complete software update necessary to remedy the recall condition. Without the update, certain driving conditions may cause the air bag sensing and diagnostic module (SDM) software to activate a diagnostic test. During this test, deployment of the frontal air bags and the seat belt pretensioners would not occur in the event of a crash.
- Consequence
- A failure of the front air bags or seat belt pretensioners to deploy in the event of a crash necessitating deployment increases the risk of injury to the driver and front passenger.
- Remedy
- GM will notify owners, and dealers will reflash the SDM software. Vehicles that have had a previous air bag deployment will have the SDM replaced. These repairs will be performed free of charge. The recall began on August 4, 2017. Owners may contact Buick customer service at 1-800-521-7300, Cadillac customer service at 1-800-458-8006, Chevrolet customer service at 1-800-222-1020, or GMC customer service at 1-800-462-8782. GM's number for this recall is 17287.
