Driving and abrupt transmission shifting issues.
On 11/19/25 , my 2021 Ford f350 burned to the ground due to engine malfunction. From what the fire department said.
I have a fuel leak on this vehicle that seams to coming from fuel filter housing or fuel pump.
At this point, nothing has happened. This is a fuel pump, bio-diesel issue that can cause a lack of power which is a safety risk. This recall has been active for 7 months with no remedy listed, but according to Ford Motor Company will require a software update? The remedy is replacing the fuel pump with a DCR valve. Waiting for the truck to breakdown and potentially leading to loss of life should not be acceptable. They know about the issue, they say no remedy, yet they are continuing to manufacture these vehicles. Are they manufacturing new vehicles with a known safety risk or did they fix the problem on newer model vehicles and just stonewalling current owners?
A large fuel leak occurred. The amount of diesel coming out of the top of the fuel filter area was so substantial that I could not drive the vehicle.
Ongoing Fuel System Failures Related to Recall 24S78 – Request for Escalated Review To Whom It May Concern, My name is [XXX] , and I am the owner of two 2021 Ford F-350 6.7L Power Stroke Diesel trucks, both of which are affected by Recall 24S78 / NHTSA Campaign 24V957 concerning biodiesel deposit accumulation in the fuel system and a pending PCM software update.

While operating my vehicle on a busy road the power failed and vehicle shut down. Saftey of myself and others were at risk as this occurred while actively driving. Upon restart attempt vehicle failed to start. Vehicle was towed to and inspected by an independent service center. Mechanic advised, based on codes from check engine, the high pressure fuel pump failed and metal shavings were in my fuel system. Mechanic replaced pump, flushed system. Upon return of fixed vehicle power dropped out, check engine light appeard again. Returned to independent service center with codes of metal shavings in fuel sytem again. Pistons replaced, still being worked on for further issues. No prior warnings, check engine lights, recall notices etc. Contacted ford dealership, advised there was no fix and nothing they can do, advised to call corporate. Called corporate who advised I'd be notified via mail when a fix was available...
This vehicle has horrible throttle response. When I take off normally then let off the gas then try and accelerate, there is a 2-3 second lag in acceleration. It’s dangerous because I’ve had times where I can’t get out of the way of oncoming traffic. Not all of these trucks have this and I want ford to rectify this for safety’s sake
Check engine light comes on almost everyday. After at least 5 minutes driving, this trucks engine will shut down with out notice. Usually when making a turn or coming to a stop light. When this happens you loose all steering control. You have to shift to neutral and try and restart. This has caused me to almost rearend a highway patrol vehicle. Very dangerous. I have had this vehicle in to the local Ford dealership on numerous occasions; however they will NOT run diagnostics to see what is happening. Have ad independant mechanic and my scan tool run tests and it always shows code P0191 fuel pressure rail faault. Maintenance is always uptodate ad fuel filters changed by dealer every 5,000 miles. Dealer and MF not honoring warrenty.
This truck on a daily basis, shuts down with out warning. Check engine light comes on some time, some times get P0191, P0171 and other codes dealing with fuel rail and pressure. Vehicle had less than 10000 miles when started. Dealer don't know what to do. Shuts off when you are in a turn and leaves you with out steering, and shuts off when coming to a stop sign, or trying to park. Fuel filters have been changed 2 times in 2 months. Truck is not safe to drive because it keeps surging and cutting off. Idle speed varies as much as 250 rpm when sitting still. Now
