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

Checked against public records, 2026-09-25

NHTSA holds 3 owner complaints for the 2015 Subaru WRX STI, and no recall campaigns.

That is too small a record to read a pattern from, so we are not going to pretend otherwise — with numbers this low one owner moves the percentage by a lot. What has been filed is grouped under the engine (2), the fuel system (1), the body and structure (1). Treat those as things to look at, not as the vehicle's known weaknesses. A thin file usually means few of these were sold or few owners filed. It is not evidence the vehicle is trouble-free, and the issues below are our own research rather than a reading of this record.

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