Ford Expedition (2005–2010): what actually fails

The documented failure patterns on used Ford Expeditions — the mileage window where each shows up, and what the repair typically costs at an independent shop. This is the same data NoLemon's Brief checks against every VIN.

2005–2010 TYPICAL 80k–180k MI $500–$2,000

Spark plug breakage on removal (5.4 3V)

Same 5.4L three-valve plug design as the F-150 of this era: plugs seize and snap during routine replacement, turning a tune-up into an extraction job. Documented plug replacement with updated one-piece plugs removes the risk entirely.

BEFORE YOU BUY
Ask for repair records covering this item. If it hasn't been addressed and the car is in or near the mileage window, price the $500–$2,000 repair into your offer — or make it the seller's problem.
