2018 Subaru WRX STI — Should You Buy One?
Typical asking price: $26,000–$36,000. This is one of the more reliable vehicles in its class — here's what to watch for anyway.
Kestrel Take
The rally-bred icon — the STI's turbo boxer, AWD, and big wing make it a hugely capable and beloved performance car, but it's a young-enthusiast magnet, so abuse is the whole risk. The EJ25 can suffer ringland failure if tuned/abused, and clutches and drivetrains take a beating. A stock, un-tracked, documented STI is a thrilling, capable car that holds value; a tuned, launched, or tracked one is a grenade. Buy stock and verify everything.
What we checked
Checked against public records, 2026-09-25
NHTSA holds 2 owner complaints for the 2018 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 airbags (1), the lights (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.
