2018 Acura RDX — Should You Buy One?

Typical asking price: $20,000–$28,000. This is one of the more reliable vehicles in its class — here's what to watch for anyway.

Kestrel Take

A reliable, value-focused compact luxury SUV — the RDX pairs Honda mechanical dependability with a comfortable, well-equipped cabin and the durable 3.5L V6 (naturally aspirated, no turbo, timing belt). It avoids the German repair bills entirely. A documented RDX is one of the most sensible used compact luxury SUVs; verify the timing belt was done (or budget for it), check the electronics, and enjoy years of low-drama, dependable ownership.

What we checked

Partly reconciled against public records, 2026-09-11

NHTSA holds 77 owner complaints for the 2018 Acura RDX, across 1 recall campaign.

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 fuel system. 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.

One recall campaign covers 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: the fuel system (34 complaints), the transmission and drivetrain (12 complaints). Those groups are in the public record and are not covered by the issues below. Treat them as something to ask about, not as absent.

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