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.
GM will notify 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. GM reports that 35,292 trucks could be affected by the recall.
Interim notices are expected to be mailed December 18, 2017. Owners will receive a second notice in February when the remedy is expected to be available. 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.
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. Refer to NHTSA Campaign number 17V664000.
