Recall 19V088000

Front Fuel Tank Overfills And Expands Causing Fuel Leak

Recall Details

The front fuel tank fuel level sensor may stick in the low fuel position, prompting the rear fuel tank to overfill the front tank. This could cause the front fuel tank to expand and become punctured on the drive shaft. Dealers will replace the rear tank fuel pump module, inspect the front tank and if needed replace the front tank free of charge to resolve the concern.

Our Quick Take

For vehicles equipped with dual fuel tanks, the front fuel tank fuel lever sensor may stick in the low fuel position, allowing the tank to overfill with fuel as fed by the rear fuel tank. If the tank is overfilled, it can expand and possibly puncture on the drive shaft causing a fuel leak and a fire hazard.

What Should You Do?

Summary
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.
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 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.
Notify
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
