When exiting the interstate and coming to a complete stop at the bottom of the exit ramp we went to make a right turn onto a two lane mountain road when we felt a hesitation and within seconds the engine began to sputter, we lost power and the check engine light came on. This was a two lane 55MPH road with no shoulder pull off. Thankfully there was no oncoming traffic in the other lane and there was also an abandoned fruit stand parking lot which were were able to drift across the road and stop in. We experienced a COMPLETE loss of power. Had there been oncoming traffic or no open parking lot just across the road we might have experiened a crash. It is important to note that we were on a vacation in the mountains and thankfully our RV was parked at the Campground we were not towing it at this time. We had to find a tow service to have the vehicle towed to the nearest Ford Dealership in the area. The Dealership notified us that there were metal shavings/flakes in the lower fuel filter housing. They told us that this was a Complete Fuel System Failure and that we would need a complete fuel system replacement of all parts. We had been notified of the recall (Safety Recall Notice 24S78/the federal safety agency Recall 24V957) in January 2025 and we had taken it to the local Ford Dealership who advised there was no fix for the problem at this time. The Dealership that our truck was towed to after this incident advised us that we would have to pay for all the repair costs (excess of $10,000) as this was still an open recall. We feel that this is a MAJOR safety issue - we were due to leave for home the following morning where we would have been towing a 7500lbs travel trailer on the interstate roads. Had we experienced this failure then it could have been truley tragic for not only us but other motorists. After this incident we called Ford Motor Company and advised them and they told us it was still considered an open recall with no fix available.
