What's wrong, in plain English

These trucks have two fuel tanks, and a sensor in the front tank tells the system when it's full. That sensor can stick, so the rear tank keeps pumping fuel into the front tank after it's already full. The extra pressure can make the front tank swell and touch the driveshaft, which can wear a hole in the tank. Fuel leaking from that hole can catch fire if it reaches a spark or flame.

What you should do

1. Check your VIN at nhtsa.gov/recalls to see if your truck is included.
2. Contact a GM dealer to schedule the repair.
3. The repair (replacing the rear-tank fuel-pump module and, if needed, the front tank) is free.

Where do I find my VIN, and what do I tell the dealer?

Your VIN is the 17-character code on the lower left of the windshield, on your registration and usually on your insurance card. Enter it at nhtsa.gov/recalls to see whether this recall is still open on your car. When you call the dealer, say you have an open safety recall and give them NHTSA campaign number 19V088000.

Official notice

Component: FUEL SYSTEM, GASOLINE:STORAGE:TANK ASSEMBLY
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.
Safety 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.
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. The recall began July 30, 2019. GM's number for this recall is N182204190.
