2015 Subaru WRX STI — Should You Buy One?
Typical asking price: $22,000–$34,000. This is one of the more reliable vehicles in its class — here's what to watch for anyway.
Kestrel Take
The last of the hydraulic-steering, big-wing STIs and a future classic. The EJ257 is the same double-edged sword as always — strong stock, fragile under a bad tune. Bought by enthusiasts and often modified and tracked. A stock, clean-title, well-maintained one is the smart buy.
What we checked
Partly reconciled against public records, 2026-09-11
NHTSA holds 3 owner complaints for the 2015 Subaru WRX STI, and no 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. 67% 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.
Not written up yet: the engine (2 complaints), the fuel system (1 complaint). 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.
