2013 Ford F-150 (3.5L EcoBoost) — Should You Buy One?

Typical asking price: $12,000–$20,000. There are 4 high-severity known issues you need to know before handing over a check.

Kestrel Take

The truck that convinced America a V6 could replace a V8. It tows well and it also has a timing chain, cam phasers, and an intercooler that condenses water — all three of which produce well-known symptoms. The 5.0L V8 in the same truck is the simpler purchase.

What we checked

Reconciled against public records, 2026-09-11

NHTSA holds 8,388 owner complaints for the 2013 Ford F-150 (3.5L EcoBoost), and no 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. 43% 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.

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

Known Issues for the 2013 Ford F-150 (3.5L EcoBoost)

Ranked by wallet impact. These are documented, recurring problems — not freak accidents.

Timing chain stretch and cam phaser rattleHigh — wallet impact

A rattle for a few seconds at cold start, then camshaft correlation codes. The chain job on a twin-turbo V6 is expensive.

Repair cost (estimate): $2,000-$4,000

Source: NHTSA complaints filed under the engine (1,644).

Condensation in the intercooler causing misfires under loadHigh — wallet impact

Humid air condenses in the air-to-air intercooler, then gets ingested at once under boost — a stumble or shudder when accelerating hard in damp weather. Ford issued a fix involving a revised intercooler and a drain.

Repair cost (estimate): $300-$1,200

Source: NHTSA complaints filed under the transmission and drivetrain (3,636), the engine (1,644).

Turbocharger wastegate and bearing wearMedium

Whistling, boost leaks, and eventually turbo replacement. Twin turbos means twice the parts.

Repair cost (estimate): $2,000-$4,000

Source: NHTSA complaints filed under the engine (1,644).

Water pump (internal, chain-driven)High — wallet impact

On the Cyclone family the water pump lives inside the timing cover and fails inward into the oil. No external leak warns you.

Repair cost (estimate): $1,500-$2,500 preventive

Source: NHTSA complaints filed under the engine (1,644).

Brake master cylinder seal failure (recall)High — wallet impact

A seal inside the brake master cylinder can roll out of position and let fluid leak into the brake booster, changing pedal feel and travel before eventually reducing braking power. Ford recalled about 225,000 2013-2014 F-150s for this. Check the VIN for recall completion before you buy, and press the brake pedal firmly for several seconds in the driveway to feel for it sinking.

Repair cost: $0 with the recall — verify it was performed

Source: NHTSA complaints filed under the brakes (1,062).

Walk-Away Red Flags

✗Cold start rattle
✗Shudder or misfire under hard acceleration in humid weather
✗Coolant loss with no visible leak
✗Aftermarket tune on a turbo truck

Good Signs

✓5.0L Coyote V8 — simpler and famously durable
✓Timing chain and phasers already replaced
✓Intercooler fix performed at a dealer
