2017 FORD F-350 SD Fuel/propulsion System Problems

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.

Experienced CP4 pump failure!!!!! Failed because the pump was not designed for diesel fuel in the United States. And FORD puts them on trucks and Refuses to recall them knowing good and well they are not designed for diesel fuel in the United States. Is our government going to continue to allow ford to do this????

This truck had a complete fuel system replaced already once when it failed while the customer was driving. We are the next owners and didn't know it had this major failure before purchase. We know this fuel pump is an issue and Ford has active law suits against them as these pumps that they continue to put even in the new Fords and all other makes of trucks are blowing up daily. Ford sees it as a revenue stream to keep their shops busy. Fuel is highly flammable and we tow a travel trailer. I would hate to see something bad happen because they won't issue a recall. There several years that are under recall currently and our year is not one of them but it has the same pump. They should not only issue recalls on all trucks that have the known failing CP4 pump, but also give the customers the option to upgrade with the after market DCR pump. The one pump that has been the #1 best replacement option. Installing a new CP4 pump only buys Ford mote time to next failure and keeps their ships full. We spent 50k on this truck. Again, it already happened once! Let's be sure to issue recalls on ALL trucks with CP4 pumps with a real solution and not just another dangerous CP4. We don't want our truck to catch on fire while driving. Its a very big safety concern!

Engine Shuts Off Upon Acceleration on the onramp to a interstate highway causing the Ford f350SD, 6.7L Diesel to come to a stop in the outside lane of Interstate I81. Engine Shutdown happened again on a 2 lane highway while passing a slow farm tractor. The problem has been confirmed by Harrisonburg Ford, Harrisonburg, VA. The high pressure fuel pump is causing metal to be distributed throughout fuel system. The complete contaminated fuel system is required to be replaced by a High Pressure Fuel Pump KIT, which the Dealer ordered against the workorder for my truck. For over a month now, My truck is parked in the dealer storage and stating they are waiting on approval to start repair. Note I have Ford's Extended Warranty. I've read online that many other owners of 6.7L Diesel trucks are having the same problems. I my opinion, a RECALL is certainly justified for this issue.

the fuel pump failed causing the truck to lose power and ultimately shutdown while driving down the interstate. no warning messages received. our safety was put at risk because the vehicle completely shut down causing us to almost get rear ended on the interstate this problem has been confirmed not only in our vehicle but thousands of other vehicles of the same year, make, and model.

Diesel coming from upper fuel conditioning module. Large amount, top appears to be broken

The Fords have two issues with the fuel system. The CP4 fuel pumps have a common failure imploding and sending metal through the fuel system, a costly repair over $12,000. The second extremely dangerous failure on the fuel filter housing. It cracks spraying fuel into the engine compartment. If not shut off immediately a fire engulfs the car. Both are extremely Common, a safety hazard and expensive repair that Ford should fix immediately.

The owners manual states I have a tank capacity of 36 gallons. On E I can only fit about 26 gallons. If I were to take my average MPG and use the advertised 36 gallons to figure out how far I would run out of fuel and this would cause the vehicle to stall while driving. Ford is aware of this issue and knows how to fix it but declined to take care of the safety repair.

2017 Ford F350 Superduty 6.7L diesel will intermittently surge/buck while towing uphill under load causing loss of power and creating unsafe driving situation. When it happens I’ve also observed electrical power loss to OBD-II port where I have accessory guage installed to monitor critical truck systems like oil temp, trans temp, coolant temp, etc.. No DTC or fault codes are generated when this happens. I haven’t taken to dealer yet but I’ve researched and read lots of truck forums where multiple Ford owners have had the same issue. When they’ve taken their truck to the dealer they’ve been told this is “normal”. I don’t agree and believe this is a serious safety issue to a consumer that suddenly loses all power and must let off all acceleration while other cars are following/around vehicle when vehicle surges. This has now happened four different times and various speeds (30-60 mph).
