Great trucks, but the 3.5 EcoBoost has two signature issues and the automatics can shudder. The engine choice drives everything you check.
The F-150 is the best-selling vehicle in America, so the used market is enormous and varied — work trucks, tow rigs, and garage queens all wearing the same body. The EcoBoost engines are strong but have well-documented quirks, and the transmissions of this era have their own tells. We inspect by powertrain.
A cold-start rattle from the timing system and cam phasers is a known EcoBoost complaint.
CHECK Be present for a stone-cold start and listen for a one-to-three second rattle before oil pressure builds.
Condensation pools in the intercooler and causes a stumble or limp mode under hard boost in humid weather.
CHECK Road test under load and feel for a misfire-like stumble when accelerating hard.
Some 5.0 trucks consume oil more than owners expect.
CHECK Check oil level and ask about consumption between changes.
Harsh shifts and a 10-speed torque-converter shudder are reported on these automatics.
CHECK Road test through all gears, feel for shudder at light throttle around 30–45 mph, and check fluid condition.
Trucks from salt states corrode brake lines and frames.
CHECK Inspect brake lines and frame rails underneath for scaling or perforation.
