This page covers 3 recalls and 11 owner complaints for the 2015 Ford F-550 Sd.
Complaints about the 2015 Ford F-550 Super Duty cluster around the engine and fuel system. On the fuel side, owners report a recurring pattern involving the secondary fuel filter and its connecting lines, specifically, fuel lines coming loose at the fitting and causing active fuel leaks, sometimes accompanied by a low fuel pressure warning on the dash. A separate report describes a newly purchased OEM replacement fuel line that arrived with a suspect retaining clip, suggesting the issue wasn't limited to aged components. One owner reports catastrophic fuel injector pump failure with metal debris contaminating the fuel lines and a complete loss of power at highway speed. On the engine side, one report describes an underhood fire. A handful of complaints also mention fuel system contamination and oxidation severe enough to require full system replacement.

By System
The 2015 Ford F-550 SD has 3 recalls, the most serious being a transmission control issue where the gear selector can display "Drive" while the truck is actually in Reverse, creating a risk of unexpected movement and a crash.
A second powertrain recall affects trucks built with ambulance or fire engine preparation packages, where the engine can shut down and require a cool-down period before restarting, potentially delaying emergency response. There is also a suspension recall specific to Life Line-modified emergency vehicles equipped with Liquid Spring aftermarket suspension kits: a mounting bracket holding the suspension fluid tank to the frame can fracture, allowing the tank to drop onto the road and become a hazard for other vehicles.
