2018 Ford F-150 (2.7L EcoBoost) — Should You Buy One?

Typical asking price: $22,000–$32,000. There is 1 high-severity known issue you need to know before handing over a check.

Kestrel Take

The small EcoBoost is the quiet success of the F-150 lineup — compacted graphite iron block, strong torque, and better economy than the V8. Paired with the 10-speed automatic it's an excellent truck, provided the transmission has had its software updates.

What we checked

Partly reconciled against public records, 2026-09-11

NHTSA holds 60 owner complaints for the 2018 Ford F-150 (2.7L EcoBoost), across 19 recall campaigns.

A big number here usually means a lot of these were sold, not that it is a bad vehicle — popular models collect more complaints for the same rate of trouble. So the total on its own says little. What is worth reading is the shape of it. 77% of them are about one thing — the transmission and drivetrain. That much concentration is a genuine pattern rather than background noise, and it is the first thing to check on any example you look at.

19 recall campaigns cover this model year. Recalls are repaired free, for any owner, with no time limit on most safety campaigns — but only if someone books it in. Ask the seller to show it was done, or have any dealer check the VIN; it takes them a couple of minutes and costs nothing.

Not written up yet: the brakes (4 complaints). That group is in the public record and is not covered by the issues below. Treat it as something to ask about, not as absent.

Counts come from the NHTSA complaint and recall database — free, public, and worth checking yourself.
