The high pressure fuel pump failed sending metal shavings through out the entire fuel system. I had no heads up and the failure left me stranded on top of a bridge. I called 911 twice and finally the cops showed up and wrecker towed me off the bridge. Ford is aware of this known issue with this make and model, and even put a recall partial recall / quick fix to increase the flow around the pump to keep it cooler. I had the quick fix recall completed but it did not prevent the failure and me being stranded on a bridge.

Vehicle went into limp mode and we towed it to the dealership. They ran diagnostics and found that the fuel filter was causing a fault for water in the fuel filter. They replaced the fuel filter and ran diagnostics again and it flagged failure for Low pressure fuel pump. They replaced the low pressure fuel pump and reran diagnostics. When they reran diagnostics it flagged for High pressure fuel pump failure and now they are in the process of tearing it down to the point of failure to find out the cause. My vehicles vin was not included in the original recall and believe that it should have been included.
