2018 Ford F-450 Super Duty

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2018 F-450 Super Duty.

The 2018 Ford F-450 Super Duty carries 10 owner complaints and 3 recalls, with engine issues standing out as the top complaint area for this model year. The model's complaint history from 2009 through 2014 shows relatively low volumes—peaking at just 2 complaints in 2011 and dropping to a single complaint in 2010—pointing to a generally stable reliability record across those tracked years. Against that backdrop, the 2018 model's complaint count of 10 alongside 3 recalls represents a noticeable uptick, suggesting researchers should weigh engine-related concerns more carefully when evaluating this particular model year.

Factory maintenance schedule OEM · verified

Normal service, condensed from the factory interval matrix.

Under the factory schedule, replace the engine oil and filter every 7,500 mi; spark plugs every 97,500 mi; coolant every 45,000 mi. The big-interval services (every 45,000 mi for coolant, and the transmission fluid) are the ones owners most often skip — on a lower-mileage example, assume the original fluids are still in it and check them first.

Reliability & federal safety record

Owner-reported issues, recalls, investigations and service bulletins on record with NHTSA — an unfiltered look at what owners actually experience.

The provided federal record for the preceding generation (2009-2014) exhibits a trend of steady recalls—three per year from 2009-2013, dropping to one in 2014—and minimal complaints, establishing a baseline of relative stability. However, the 2018 target year falls beyond this earlier arc, and its data implies a shift away from that stability by registering five total complaints and one fire complaint compared to the near-zero complaint figures of the earlier years. These 2018 complaints are heavily concentrated in the engine and fuel/propulsion systems, which account for four of the five reports, though the data does not specify the root cause. Given this escalation in federal complaints and the severity of a fire incident relative to the prior generation's record, the 2018 model is a riskier proposition; prospective buyers should only proceed if a rigorous pre-purchase inspection specifically clears the engine and fuel systems.
