What's wrong?
The high-pressure fuel pump on affected 2018 Navigator, Expedition, and F-150 vehicles feeds the 3.5L GTDI V6 engine. It raises fuel pressure before fuel reaches the engine, and its flange holds the pump assembly tightly against the engine.
On these vehicles, the weld that joins the pump body to that mounting flange was made with a misaligned laser fixture. That weakens the body-to-flange joint. As the engine runs, stress at the weak weld can let the pump move, then fracture the weld and allow oil or fuel to leak.
Owners can notice drivability symptoms before a leak if pump movement causes fuel pressure to drop. If the low fuel pressure continues, the Service Engine Soon light can turn on in the instrument cluster.
Who's affected?

What's the safety risk?
A fuel leak near an ignition source increases the risk of a fire. Pump movement before a leak can cause low fuel pressure, drivability symptoms, and a Service Engine Soon light. If your VIN is included, schedule the repair soon and ask the dealer what to do if those symptoms appear. Repair is free at any franchised Lincoln dealer.
What should I do?
- Check your VIN to confirm your 2018 Lincoln Navigator, Expedition, or F-150 is included in this recall.
- Contact a franchised Lincoln dealer to schedule the free high-pressure fuel-pump replacement that fixes the fracture-prone pump welds and fuel leak risk.
- Bring the recall notice if Lincoln mailed one. If not, reference recall number 18V392 when you call.
- Avoid parking near ignition sources if you smell fuel or see a fuel leak before the repair is complete.
What happens at the repair
At the dealer, a Lincoln technician replaces the high pressure fuel pump and the related components covered by recall 18V392. The replacement parts and labor are free under the recall. This campaign does not include a separate reimbursement program because the original warranty program already provides a free repair for this concern. If you already have repair paperwork for the fuel pump, ask the service desk how the warranty coverage applies.
