Kestrel Take

A right-sized three-row crossover — smaller than a Highlander but with a usable third row and a genuinely nice cabin. The 3.3L V6 (no turbo, no CVT, timing chain) is the one to have and is quite durable; the 2.4L GDI falls under the Theta II recall. A comfortable, value-packed family SUV; prefer the V6 and verify any Theta engine documentation.

What we checked

Reconciled against public records, 2026-09-11

NHTSA holds 252 owner complaints for the 2018 Kia Sorento, across 3 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. 44% of them are about one thing — the engine. 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.

3 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.

Looked at and set aside: the lights (41) — 41 lighting complaints on file; real, but usually a bulb or a housing rather than a reason to walk.

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

The 2.4L GDI falls under the recall/extended warranty for bearing wear/knock; verify software/engine work. The 3.3L V6 is not affected and is preferable.
