What's wrong?
The dual fuel tank system on these 2017-2019 diesel Silverado 2500, Sierra 3500, Sierra 2500, and Silverado 3500 trucks stores extra diesel in a rear auxiliary tank and transfers it to the front tank as the truck uses fuel. The rear tank needs an open vent so air can replace fuel as it moves, which keeps the tank from being pulled inward by vacuum.
On affected trucks, debris can block the vent opening on top of the rear fuel tank. During fuel transfer, that blockage lets vacuum build inside the rear tank until the tank collapses. Once the tank is damaged, the fuel pump module can stop moving enough diesel to the front tank. The engine can then stumble or stall because it is not getting enough fuel.
Before that happens, the driver can see inaccurate or erratic fuel gauge readings, engine stumble, a check engine light, or a slow engine start. Those signs point to the fuel transfer problem behind recall 23V047.
Who's affected?
Covers four heavy-duty pickup lines across the 2017, 2018, and 2019 model years, all tied to the auxiliary diesel fuel tank assembly.

What's the safety risk?
An engine stall increases the risk of a crash because the truck can lose power while moving. Warning signs include erratic fuel gauge readings, engine stumble, a check engine light, or slow starting. If those happen, drive cautiously, avoid long trips, and schedule the recall repair soon. Repair is free at any franchised Chevrolet dealer.
What should I do?
- Check your VIN to confirm your 2017-2019 Chevrolet or GMC Silverado 2500, Silverado 3500, Sierra 2500, or Sierra 3500 with the dual fuel tank option is included in this recall.
- Contact a franchised Chevrolet or GMC dealer to schedule the free inspection and repair: the dealer checks the rear fuel tank and fuel pump module, replaces parts as needed, and adds a vent hose to address the stall risk.
- Bring the recall notice if you have it, and reference recall number 23V047 when you call.
- Watch for engine stalling or fuel-transfer problems before the repair, and pull over safely if the truck loses power.
What happens at the repair
At the dealer, a Chevrolet technician inspects the rear fuel tank and fuel pump module, replaces parts as needed, and adds a vent hose to the rear tank assembly. The recall repair is free, with parts and labor covered. If you've already paid for a related fuel tank or fuel pump repair, GM's reimbursement plan covers eligible documented costs. Ask the service desk how to submit prior repair paperwork under that plan.
