Chevrolet Silverado 3500 and GMC Sierra 3500 can stall

NHTSA campaign 26V129000 · Reported 2026-03-05 · General Motors, LLC

high How serious is it? About this label

Serious — an engine that stalls without warning while you are moving can lead to a crash, so get the update installed as soon as you can.

What's wrong, in plain English

These trucks have two fuel tanks, and a pump is supposed to move fuel from the rear tank to the front one. That pump may not move enough fuel forward. If the front tank runs low even though there is still gas in the rear tank, the engine can stall — cutting power while you are driving, possibly in traffic. The repair is an engine computer software update, done at a dealer or sent to the truck wirelessly.

What you should do

1. Check your VIN at nhtsa.gov/recalls to confirm your truck is affected. 2. Accept the over-the-air update if offered, or book a free dealer visit for the software update. 3. Call GMC at 1-800-462-8782 or Chevrolet at 1-800-222-1020 and reference recall N262544420.
