A fuel leak concern is prompting GM to recall 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. 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.
Roughly 18,574 trucks are believed to be impacted. 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. Owners were mailed interim notices informing them of the safety risk on March 5, 2019. Owners will receive a second notice when the remedy becomes available. GM’s number for this recall is N182204190.
Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to www.safercar.gov.
