2018 Subaru Legacy — Should You Buy One?
Typical asking price: $12,000–$18,000. This is one of the more reliable vehicles in its class — here's what to watch for anyway.
Kestrel Take
An Outback that doesn't want you to know it's an Outback. Same platform, same CVT questions, same excellent all-weather manners, several thousand dollars cheaper because it isn't shaped like an adventure. Great value if the CVT checks out.
What we checked
Partly reconciled against public records, 2026-09-11
NHTSA holds 117 owner complaints for the 2018 Subaru Legacy, 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. 34% of them are about one thing — electrics and electronics. 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.
Not written up yet: the engine (10 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.
