According to Ford Recall 24S78/24V957: "On your vehicle, it may be possible for aged biodiesel deposits to form on internal high pressure fuel pump components.

- [511604\-F](/bulletins/10237142.md), 2023-07-05, Service bulletin: FUEL SYSTEM, GASOLINE; STRUCTURE. According to Ford Motor Company Recall 22V925: On your vehicle, the paint on your fuel tank may not have adhered properly and may peel. Extended peeling may expose the metal on the fuel tank and lead to long\-term corrosion. Over time, corrosion in certain areas of the fuel tank may ultimately progress to a fuel vapor leak or a liquid fuel leak. If a fuel leak occurs due to corrosion, a malfunction indicator lamp may illuminate, or a fuel odor or liquid fuel may be observed. A fuel leak in the presence of an ignition source increases the risk of a fire. This is the final notification received from Ford.
- [511443](/bulletins/10208119.md), 2022-03-01, Service bulletin: ELECTRICAL SYSTEM; FUEL SYSTEM, GASOLINE. The high pressure fuel pump \(HPFP\) on your vehicle may fail prematurely. A high pressure fuel pump failure may introduce internally failed component debris into the fuel system potentially causing fuel starvation. Vehicle occupants may notice a Malfunction Indicator Lamp illuminating, a fuel leak, abnormal engine noise, or a change in drive quality. Fuel starvation may result in an unexpected loss of motive power, which can increase the risk of a vehicle crash without prior warning The remedy for this condition is not currently available. We are making every effort to finalize the remedy as quickly as possible, and will service your vehicle free of charge \(parts and labor\) when the remedy is available.
