General Chevrolet Silverado 3500 and and GMC Sierra 3500 recall: The rear fuel pump may not transfer adequate fuel to the front tank

Recall published 8 months ago

The rear fuel pump may not transfer adequate fuel to the front tank, causing an engine stall.

The hazard: Fuel leak or fire risk

This campaign concerns a fire or fuel-leak risk, the one vehicle hazard that can harm you while nobody is driving the car.

What the notice says: An engine stall increases the risk of a crash.

Why it matters: The vehicle may leak fuel, or a component may overheat enough to start a fire. Several of these campaigns involve a fire risk while the vehicle is parked and switched off, which is why the parking instructions matter.

What to do about Fuel / fire

General — This campaign concerns a fire or fuel-leak risk, the one vehicle hazard that can harm you while nobody is driving the car.

  1. Read the risk note above carefully. If it says to park outdoors and away from buildings, do that tonight — the fire can start with the engine off and the key indoors.
  2. Park away from the house, the garage and other vehicles until the repair is finished, and do not leave it charging unattended if it is electric.
  3. Keep the repair order the dealer hands you. It is your proof the campaign was closed out, and it matters at resale.
  4. Check your own VIN at nhtsa.gov/recalls before you do anything else. A campaign covers a build range, not every car of that model year, and the VIN lookup is the only thing that confirms yours is included.

Costs, reimbursement and your rights

The repair itself is free. What people most often miss is that money already spent can frequently be claimed back.

  • If you paid for the same repair out of pocket before the recall was announced, ask the manufacturer for reimbursement. Carmakers must run a reimbursement plan for pre-notification repairs; you will need the original invoice.
  • Towing is normally covered where the vehicle is unsafe to drive, and loaner cars or rental reimbursement are often available on long parts delays. Neither is usually offered unless you ask.
  • A dealer may not charge a diagnostic, inspection or shop-supplies fee for recall work. If one appears on the estimate, query it before you sign.
  • If a dealer refuses the repair, delays it unreasonably or tries to bill you, complain to the manufacturer’s customer line, then to NHTSA. Those complaints are logged against the campaign.
