2018 Lexus LS 500 — Should You Buy One?

Typical asking price: $45,000–$62,000. This is one of the more reliable vehicles in its class — here's what to watch for anyway.

Kestrel Take

The reliable flagship — the LS 500 delivers genuine flagship luxury, a stunning cabin, and a twin-turbo V6, with the crucial Lexus advantage: it's far more dependable and cheaper to own than the German flagships. If you want a big luxury sedan without the flagship repair-bill anxiety, this is the one. A documented LS 500 with full history is arguably the smartest used flagship buy; verify service and the (many) tech features, and enjoy the peace of mind.

What we checked

Partly reconciled against public records, 2026-09-11

NHTSA holds 4 owner complaints for the 2018 Lexus LS 500, across 2 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. 50% of them are about one thing — wheels and bearings. 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.

2 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: wheels and bearings (2 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.
