The defect

Reported January 7, 2021 by General Motors, LLC

FUEL SYSTEM, GASOLINE:STORAGE:TANK ASSEMBLY

NHTSA 19V088000
The defect
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.
The 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.
The fix
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.

Checking your own car

A recall applies to a range of VINs, not to every 2018 Gmc Sierra 3500 built. To confirm whether yours is affected, find the 17-character VIN on the driver-side dashboard or door jamb and enter it in NHTSA's official lookup.

Repairs for safety recalls are free and never expire. A dealer cannot charge you, and cannot refuse on the grounds that the car is old or out of warranty. If one does, call the NHTSA hotline on 1-888-327-4236.
