2 safety recalls, most serious first
1. Fuel system
What's wrong, in plain English: Fuel lines, tank or pump. Fuel problems usually mean a leak, and leaks mean fire risk. The rear fuel pump may not transfer adequate fuel to the front tank, causing an engine stall.
What could happen: An engine stall increases the risk of a crash.
The fix: The vehicle's engine control module (ECM) will be updated by a dealer or through an over-the-air (OTA) update, free of charge. Owner notification letters were mailed April 8, 2026. Owners may contact GMC customer service at 1-800-462-8782 or Chevrolet customer service at 1-800-222-1020. GM's number for this recall is…
What to do
- Check whether your car is affected: enter your 17-digit VIN at nhtsa.gov/recalls. A recall covers specific VINs, not every 2026 SIERRA 3500.
- Book a repair at any authorized GMC dealer. Quote NHTSA campaign 26V129000 (manufacturer code N262544420).
- The repair is free. By US law, safety recall repairs cost the owner nothing, no matter the car's age or mileage.
- Manufacturer hotline: 1-800-462-8782.
- Buying this car used? Ask the seller for proof the recall was completed, or run the VIN yourself before paying.
