2018 Audi Q7 — Should You Buy One?

Typical asking price: $28,000–$40,000. This is one of the more reliable vehicles in its class — here's what to watch for anyway.

Kestrel Take

A superb three-row luxury SUV — the second-gen Q7 is spacious, beautifully built, and great to drive, with standard Quattro and a lovely cabin. It's a used Audi SUV, so budget for the supercharged V6's cooling, carbon, air suspension, and electronics. A documented Q7 with full history is one of the best three-row luxury SUVs; a cheap neglected one is a risk. Buy on records, verify the engine and air suspension, and keep a repair fund.

What we checked

Reconciled against public records, 2026-09-11

NHTSA holds 141 owner complaints for the 2018 Audi Q7, 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. The largest single group is the engine at 27%. That is notable without being overwhelming — worth checking, not worth panicking about.

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 (23) — 23 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.
