NHTSA Complaint #11703720 — 2017 FORD F-350 SD

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.
