The documented failure patterns on used Ford F-150s — 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.

2004–2010TYPICAL 80k–180k MI$500–$2,000
Spark plug ejection / breakage (Triton V8)
5.4L three-valve plugs seize and snap on removal; 2004–2008 two-piece plugs are worst. Ask if plugs have been done — a completed job with updated plugs removes the risk.
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.
2011–2016TYPICAL 80k–170k MI$2,000–$4,500
3.5 EcoBoost timing chain & cam phaser wear
First-gen 3.5 EcoBoosts stretch timing chains and wear cam phasers — a rattle on cold start is the tell. Ignored, it ends in jumped timing. Records showing the chain/phaser job done are worth real money; a cold-start listen is mandatory.
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 $2,000–$4,500 repair into your offer — or make it the seller's problem.
2017–2020TYPICAL 40k–140k MI$1,500–$3,000
Cam phaser rattle (10-speed era 3.5/2.7)
Ford extended coverage on rattling cam phasers for many of these trucks after widespread complaints. Listen for a two-second startup rattle. Ask whether the phaser TSB was performed under the extended program — free then, $1,500+ now.
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 $1,500–$3,000 repair into your offer — or make it the seller's problem.
