2015-2021 Ford Super Duty Fuel Leaks Spur NHTSA Probe

The National Highway Traffic Safety Administration (NHTSA) has opened a number of investigations pertaining to issues with Blue Oval models as of late, a list that includes transmission woes with 2011-2014 Ford F-150 pickups, two crashes involving Ford Mustang Mach-E crossovers when BlueCruise was activated, and 2022-2023 Ford Bronco Sport and 2022 Ford Escape models equipped with the turbocharged 1.5L I-3 EcoBoost engine over an issue with fuel injectors that may crack and leak fuel inside the engine compartment. Now, that list has grown again, this time, to include 2015-2021 Ford Super Duty pickups experiencing fuel leaks.

The NHTSA has now opened an investigation into select 2015-2021 Ford Super Duty pickups equipped with the turbocharged 6.7L V8 Power Stroke diesel engine after receiving 27 complaints of fuel leaks stemming from a fracture in the secondary fuel filter housing. Of those 27 complaints, 12 reportedly led to fires. Ultimately, the NHTSA notes that 210,960 Ford Super Duty pickups could be affected by this issue.

The NHTSA’s Office of Defect Investigations (ODI) notes that it has already contacted both Ford and the manufacturer of these defective filter housings, Allevard Sogefi USA (Sogefi) to gather information on this particular problem. During that query, it discovered that the low-pressure fuel system in affected Ford Super Duty pickups is capable of a maximum operating pressure of 8.5 bar, while the secondary fuel filter was only tested to handle up to 7 bar during the manufacturing process.

In 2022, Ford and Sogefi made changes to the Super Duty and its filter that are believed to have rectified the problem, but owners of older models are still facing the potential of a pretty serious issue that may lead to a fire. As a result, ODI has opened a preliminary investigation to determine the scope and severity of this issue, and determine if further action should be taken.

    Well maybe if Obama had left the DIESEL engines ALONE, these things may not happen. But because of the EPA crap like having to use DEF, it’s caused a LOT of issues with not just pickups from Ford. ANYTHING Government touches to make “your life better”, ALWAYS ends in failure.

    EB1959, that is the silliest thing I have heard all day. Should we also blame him for the decades of issues Ford has had with Super Duty trucks as well? smh. Death wobble, bad engines, extreme rust, and cabs that crush in and kill you? Really dude.
