Chevrolet is recalling 9,389 2003-2004 Express and Savana vans with a left side cargo door in cold-weather states because water and road contaminants can collect around the fuel filler pipe and corrode it. Significant corrosion can let fuel leak during refueling, which increases fire risk near an ignition source; the dealer repair will be free once available.

What's wrong?
The fuel filler pipe on 2003-2004 Express and Savana vehicles is the metal tube behind the fuel door. It carries gasoline from the filler neck down into the fuel tank when you refuel. A protective conduit surrounds that pipe, with the job of shielding it from spray, dirt, salt, and debris kicked up from the road.
On affected vans with a left side cargo door, that protective conduit traps water and road contaminants against the filler pipe instead of keeping them away. In states where winter salt and wet roads are common, the trapped material sits against the metal and starts corrosion. As the pipe rusts, its wall weakens and the sealed path from the fuel door to the tank is no longer reliable.
There is no warning sign before failure. An owner will not necessarily see the corrosion from outside the van, so the defect can stay hidden until the filler pipe is inspected or repaired.

A matching year and model does not confirm inclusion. Check your VIN to confirm whether your specific van is included.
What's the safety risk?
Corrosion in the fuel filler neck can let fuel leak during refueling. Fuel near an ignition source increases the risk of fire. Avoid smoking or open flames while refueling, and schedule the recall repair soon if your VIN is included. Repair will be free at any franchised Chevrolet dealer once available.
What should I do?
- Check your VIN to confirm your 2003-2004 Chevrolet Express or Savana is included in this recall.
- Contact a franchised Chevrolet dealer and ask when the free fuel-filler-neck repair is available for your VIN.
- Reference recall number 12V388 when you call, especially if you never received the owner letter mailed on October 1, 2012.
- Schedule the fuel-filler-neck replacement that fixes corrosion in the fuel filler pipe and reduces the chance of a fuel leak during refueling.
- Avoid refueling near ignition sources until the repair is complete.
What happens at the repair
At the dealer, a Chevrolet technician installs a new fuel filler neck on the affected van. The work addresses corrosion risk at the fuel filler pipe, where trapped water and road contaminants can damage the pipe under the protective conduit. The final dealer repair will be free once it is open for your VIN. Parts and labor are covered under the recall, so confirm the repair status when you schedule service.
