The contact owns a 2015 Ford F-350. The contact stated that a certified mechanic had installed a disaster kit on the vehicle to prevent a fuel system failure. The independent mechanic later found metal shavings inside the filter going into the manifold. The independent mechanic recommended that the fuel pump be replaced. The contact was concerned that the replacement of the fuel pump with the same part would be a temporary fix. The vehicle was not yet repaired. The dealer was contacted and advised the contact to take the vehicle in for a diagnostic test. The manufacturer was not contacted. The failure mileage was approximately 81,000.

This vehicle developed a fuel leak in the area of the top of the engine which resulted in a fire that destroyed the vehicle. I spoke to the Ford Motor Company and they said that there are no recalls or Technical Service Bulletins regarding this. I just wanted to make you aware of my experience so if anyone else experienced this it may show a pattern. Thank You

1/4/2022 – TRAVELING TO SOUTHERN OHIO IN F-350. Engine light came on. Truck info screen showed Exhaust Fluid System Fault – indicating truck would lock to 50 mph within a certain number of miles, then possibly shut down. Finally got in touch with Ford dealership in Chillicothe and took truck there. They determined it was a DEF heater and pump causing the issue, and that it would be covered by Ford as an extended warranty issue. Ford decided our truck was not covered. On 1/11, Ford added a new campaign – 21M01, Reductant Heater and Sender Assembly, covering the cost of replacement of these items. We were told we needed to pay the repair and Ford would reimburse. To this date, we have not been reimbursed - in fact have pretty much been ignored. The sensor recalibration they did caused the particulate filter to fail. Ford has said they won't replace, even though service manager has said the filter failed because Ford had them recalibrate the sensor. We could have been stranded 140 miles from home because of this design fault that Ford knows about - but is not being forced to take care of. Our truck has less than 64000 miles on it and was purchased new by me in April 2014. Will you please strongly encourage Ford to stand by this defective equipment they have installed in their vehicles, as their 'customer satisfaction campaigns' do not adequately encourage them to fix these faulty issues. Volkswagen and Audi both stand by their defective equipment. Consumer wants assistance getting Ford to pay for repairs.

CP4 High pressure fuel injection pump blew up, causing the truck to need a 17,000$ fuel system at 93k miles. Thankfully I had warranty with Ford- however what happens when it’s over and it goes again? Pay 17,000$ out of pocket? Ford needs to recall this just like dodge / Cummins. 17,000$ out of pocket can be crippling to the average American.

Check engine light came on in my 2015 F 3 50 super duty crew cab truck. Upon inspection at the Ford dealership I was told the Reductant Heater And Sender Assembly Need to be replaced at a cost of $1100. This is happening within 60 days of heat sensor recall being done. When I look into this topic this repair has a recall on it for F2 50s through F5 50’s including various years up to 2015, but the F3 50 is only up to 2012.
