What's wrong?
The fuel tank on the affected 2007 Mercury Montego and Five Hundred stores gasoline and connects to the filler neck, the tube used when you refuel. That connection depends on a welded joint between the tank and the filler neck spud, which is the short fitting where the filler neck attaches to the tank.
On these vehicles, that weld was not made with consistent strength. In a severe rear impact, the joint can crack instead of holding as designed. A cracked joint can let fuel escape from the tank area, which creates a fuel leak risk and can also trigger an emissions malfunction indicator light.
There is no warning sign before failure. After the joint cracks, an owner can notice a fuel odor, see the emissions light, or find signs of leaking fuel near the tank or filler area.
Who's affected?
The Montego and Five Hundred are listed under the same fuel system component.

A matching year and model does not guarantee inclusion. Check your VIN to confirm whether your specific sedan is included.
What's the safety risk?
Fuel leakage near an ignition source can result in a fire. Avoid open flames or sparks around the vehicle, and schedule the recall repair soon if your VIN is included. Repair will be free at any franchised Mercury dealer once available.

What happens at the repair
At the dealer, a Mercury technician replaces the fuel tank covered by recall 11V355. The work addresses the weld area between the fuel tank and the fuel filler neck spud, where the joint strength was the concern. The fuel tank replacement is free under the recall, with parts and labor covered. The source does not describe a separate reimbursement program, so this section does not add a reimbursement step.
