   While driving a 2017 Ford F-350 Super Duty Dually (6.7L Power Stroke) at highway speeds while towing a horse trailer containing live animals, a sudden and catastrophic failure of the secondary fuel filter occurred. The driver noticed a severe and sudden drop in fuel economy, accompanied by a strong diesel odor inside the cabin.Upon arriving safely at our destination, an inspection of the engine compartment revealed that the top plastic cap of the OEM secondary fuel filter housing had completely cracked right in the top middle. Diesel fuel was actively spraying out under extreme low-pressure system pressure (approximately 8.5 bar) all over the hot engine compartment.The pressurized diesel fuel completely saturated the front hood insulation liner, soaked the entire engine, coated the undercarriage, front left tire, all four rear dually tires, the truck bed, and the entire front face of the horse trailer. The fuel exposure has already caused multiple rubber gaskets and body-to-hood weatherstripping seals at the rear of the engine compartment to swell and degrade. This massive, pressurized fuel leak created an imminent, severe risk of a catastrophic engine fire while the vehicle was traveling at speed with a heavy load. The truck wasted roughly an entire 40-gallon tank of fuel (over $175 in extra fuel costs) during the transit due to the severity of the leak.This vehicle is a direct match for the vehicle and component population currently under active NHTSA Investigation PE24014. The Allevard Sogefi USA plastic fuel filter housing failed exactly as described in the federal probe due to over-pressurization. I have retained the defective cracked filter, photographic proof of the failure and subsequent vehicle/trailer damage, and fuel receipts as evidence.

   I have a 2017 ford f350 diesel 6.7 and replaced the low pressure fuel pump in 2022 at about 57000 miles. Then again in July of 2026 the fuel pump has had to be replaced again at 68000 miles. I read that many 2022 ford vehicles were recalled in that year for a bad fuel pump. So I think I might have been given a bad fuel pump from that year 2022 and now its bad again. This is a know problem for fords I dont understand why there is not a recall for these pumps. Ford is been building bad pumps for a long time and are getting away with it, A fuel pump should not have to be replaced after 3 years. The work was all done at the Beach Ford Dealership in myrtle beach sc 29575.

   The contact owns a 2017 Ford F-350 equipped with Goodyear Tires, Tire Line: Wrangler All Terrain Adventure, Tire Size: LT275/70/R18, DOT Number: (N/A). While the contact's friend was driving 55 MPH, there was a blowout of the rear passenger’s side tire. The driver prevented a crash; however, the failure caused a significant amount of damage when the truck bed lowered and nearly separated from the chassis, the hubcap detached, and the exhaust pipe was bent in half. The driver pulled over to a truck stop and installed the spare and secured the truck bed to the frame with harness straps to prevent the truck bed from separating. The contact notified the manufacturer about the failure and requested that the tire be shipped for inspection to determine any potential liability. The contact had not yet submitted the tire or any documentation to the manufacturer. The failure mileage was approximately 10,000.

   I recently replaced a defective reductant (DEF) pump and wiring harness due to corrosion. The cause and repairs were diagnosed and performed by a ford dealership. Without addressing the issue the vehicle would randomly engage a "limp" mode and limit the speed to 50 mph, forcing the driver to operate at unsafe speeds on freeways and highways. Defect is a hazard to driver and other vehicles due to the unpredictable speed control caused by the defective parts. Ford is aware of the defective part and issued a Technical Service Bulletin (TSB) 23-2161.

   I am filing this complaint regarding my Ford F-350, VIN [XXX], which caught fire on XXX. The truck had approximately 130,000 miles, which I consider low mileage for a properly maintained diesel Ford F-350. These trucks are known for long service life, and many Ford diesel trucks routinely remain in service for 20 years or more and exceed 250,000 miles when properly maintained. For that reason, I did not expect a sudden and catastrophic fire in a truck with only 130,000 miles. While driving, passing motorists alerted us the truck was on fire. The fire appeared to originate in the engine compartment and spread extremely rapidly. Within a very short period, the front of the truck was engulfed in flames and sustained catastrophic damage. Based on the speed and severity of the fire, I am concerned a failure in the engine compartment, fuel system, electrical system, or another vehicle component may have caused or contributed to the fire. This truck has been well maintained, kept clean, and responsibly cared for. I followed the manufacturer’s maintenance guidelines and did not expect a sudden engine-compartment fire. After the fire, I found reports of other F-350 fires and references to fire-related complaints and investigations. This raises serious concerns Ford may have known of a potential fire risk involving these trucks. This incident created major safety hazard not only to the occupants of the truck, but to other motorists and anyone nearby. Had passing drivers not alerted us, the outcome could have been far worse. The severity of the fire required a major emergency response, including multiple fire trucks and police. A vehicle fire of this magnitude presents an obvious risk of serious injury or death. I request NHTSA investigate Ford F-350 and vehicle fire incidents to determine whether a defect involving the fuel system, electrical system, or related parts may cause these trucks to catch fire without warning.

   Factory Ford 20” wheels with Factory Installed Michelin 275/65 R20 LTX A/T2 tires. Tires have just under 30,000 miles on them and still have more than 50% tread. Tread wear is even. Tires have been rotated. Truck has 73,000 miles but had different wheels and tires for first 43,000 miles. I stored these wheels and tires inside climate controlled building. When my aftermarket tires wore out, I put these back on. They had 10 miles on them when I took them off. I have had them on since April 2022. On Friday June 5th, 2026 I was traveling about 60 MPH and had a catastrophic blow-out of the passenger side rear tire. The tires blew completely apart and the wheel hit the ground and the back side of the wheel broke off, before I could get over to the side of the road the tire beat the bed and running board to pieces and even damaged the exhaust and bumper. The wheel was ruined. Thousands of dollars in damage. All the tires are in good condition, not dry rotted, no cracks, the truck has been indoors in a garage. They hold air. TMPS works and I check my pressure all the time. I had just set the air pressure early that morning before leaving. The tires are less than 10 years old which is the date for replacement. They have more than half their tread. No cracks. They hold pressure perfectly. They are worn evenly. No reason for the tire to have blown out other than a manufacturing defect. When I got stopped there was a huge hole in tire and no tread on it at all.

   I am filing a complaint regarding deceptive and potentially fraudulent practices by a dealership. I visited the dealership to look at two Ford trucks that were both advertised as having clean titles and clean Carfax reports with no major history. Vehicle 1: VIN: [XXX] This truck appeared to have significant undisclosed flood damage. There was visible water inside trim areas, mold present, and water movement could be heard and seen when braking. It was clear the vehicle had been exposed to water damage despite being advertised as clean. Vehicle 2: VIN: [XXX] This truck appeared to have undisclosed front-end damage consistent with a prior accident. The damage seemed to be intentionally concealed and was not disclosed in the listing. When I questioned the salesperson, he acted dismissively and claimed no knowledge of any issues, despite the problems being obvious. Both vehicles were advertised as clean with no significant history, which I believe is misleading and potentially fraudulent. This raises serious concerns about the dealership’s business practices and the safety of vehicles they are selling. I request that this matter be investigated. Thank you.

    My truck had a recall for the door locks freezing, which my truck had an issue with. The dealer performed the recall and 1 of the doors continued to freeze. The door will not latch and it will open when driving down the road. I took it back to the dealer and they charged me to diagnose and confirm it's still doing it. They will not repair it again, they said the recall repair was inadequate and it would cost 900$ to fix.

    Driving uphill at approx 20mph near my home. Loud bang/explosion from engine or front driver-side wheel well. Red alarm flashed on instrument cluster (something like “Front Brake Failure”) and strong odor of fuel or exhaust entered cab. I immediately pulled into a pullout and put vehicle in park when I noticed flames coming from the engine compartment through the gaps in hood and wheel well. I splashed a small amount of water on the driver side front tire, but the fire continued to grow. I backed away to a safe distance and called 911. Within 5 minutes, the entire engine compartment was on fire and I captured on video explosions as the fire raged Local fire department arrived within 15 minutes, but the entire engine and cab had already been destroyed by fire. Had I been driving at high speed or with passengers, this incident could have resulted in serious burn injuries and death. Had I been driving during summer months, this incident would have caused a devastating wildfire. Had I been in traffic, I may have caused a multi-car wreck. There were absolutely no warning indicators that such a violent incident could occur. Tow truck driver said it may have been a fuel filter issue which has caused other Super Duty’s to experience sudden and catastrophic engine compartment fires. Minimal research showed me that NHSTA is investigating Ford Super Duty for this very issue. My F350 is model year 2017. I also have video of fluids dripping from the burning vehicle and the droplets are on fire which leads me to believe that leaking fuel — possibly from a cracked plastic filter — may be to blame for this incredibly dangerous incident. The vehicles remains have been searched by California Highway Patrol and the remains are currently being investigated by State Farm Auto Insurance claims experts.

    Dear NHTSA, On two separate occasions—May 2025 and December 2025, approximately six months apart—I experienced fuel leaks from the upper fuel filter on my 2017 F-350 while driving. Both filters had previously been replaced with genuine Ford parts. I am deeply concerned that my safety was compromised during these incidents. In both cases, diesel fuel was leaking down the engine compartment without any warning indicators or alerts on the dashboard. The only indication of a problem was the smell of fuel, which I initially assumed was external. It wasn’t until I stopped the vehicle that I discovered a steady stream of fuel leaking. The most recent occurrence happened while I was on vacation, approximately 650 miles from home. There were no prior symptoms or warnings, making it extremely difficult to detect while driving, as the smell dissipates in the wind. In my opinion, this represents a significant safety hazard. Diesel fuel streaming down a hot engine could easily result in a fire, posing a serious risk to both the driver and passengers.

    I have a 2017 F-350 SuperDuty with the Engine Block Heater option, two recalls have been issued related to a condition that can cause overheating of the power cord with the possibility of a fire. Recall 18V-894 and 19V-278 have both been applied and verified by Ford Customer Service. During the recent cold weather in the Houston, Texas area, the engine block heater was used to keep the engine warm to assist with starting. When I disconnected the power cord the was hot enough to have melted the plug to the point where the blades in the plug were loose and I had to use gloves to separate the engine heater cord from the extension cord. This should have been fixed under one or both of the previous recalls. It represents an electrical hazard that could lead to fire and loss of property. I asked Ford to remedy the situation under case XXX and they have declined to resolve the hazard. Please review this case and have Ford issue a third recall to remedy this safety issue. I have provided pictures to assist in your determination. Regards, [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
