What is wrong

General Motors, LLC (GM) is recalling certain 2025-2026 Chevrolet Silverado 3500, and GMC Sierra 3500 vehicles with gasoline engines and dual fuel tanks (RPOs L8T and N2N). The rear fuel pump may not transfer adequate fuel to the front tank, causing an engine stall.

What can happen

An engine stall increases the risk of a crash.
