2018 Lincoln Navigator — Should You Buy One?

Typical asking price: $36,000–$54,000. This is one of the more reliable vehicles in its class — here's what to watch for anyway.

Kestrel Take

A genuinely world-class full-size luxury SUV — the redesigned 2018 Navigator's twin-turbo V6, sumptuous cabin, and huge space made it a legitimate rival to the German and Cadillac flagships, and it holds value well. Watch the EcoBoost V6's cooling/cam-phaser items and the air suspension. A documented Navigator with full history is a superb, spacious luxury hauler; verify the twin-turbo health, air suspension, and electronics and buy the maintained one.

What we checked

Reconciled against public records, 2026-09-11

NHTSA holds 52 owner complaints for the 2018 Lincoln Navigator, across 12 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. 38% 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.

12 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.

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