VEHICLE SHUT DOWN WHILE IN MOTION ON HIGHWAY WHICH CAUSED FOR BRAKES AND STEERING TO FAIL. VEHICLE WAS TOWED TO SUN STATE FORD DEALERSHIP WHERE THEY DID A DIAGNOSIS. THEY FOUND EXCESSIVE AMOUNTS OF METAL IN THE HIGH PRESSURE FUEL SYSTEM. THEY HAD TO REPLACE THE ENTIRE FUEL SYSTEM PLUS REPLACED ALL INJECTORS WHICH NOW HAS AN OPEN INVOICE OF $15,923.97. AFTER RESEARCH WE FOUND OUT THAT THERE IS A RECALL ON THE CP4 WHICH IS THE MANUFACTIRE RECALL NUMBER 24S78 AND NHTSA RECALL NUMBER 24V957. FORD IS NOT WILLING TO COVER THE COST OF THE RECALL REPAIRS AND THE DEALERSHIP IS NOT COOPERATING AS WELL. THIS IS A COMPANY VEHICLE LOSING THE COMPANY $3K PER DAY.

High pressure fuel pump failed while driving towing a trailer. Was able to pull over safely, entire fuel system needs to be replaced. Unknown if anything else was damaged yet. Vehicle is still in for repairs, estimate is between 9-13k parts and labor. I hope it didn't destroy the entire engine.
