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
Reconciled against public records, 2026-09-11
NHTSA holds 2 owner complaints for the 2018 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. 50% of them are about one thing — airbags. 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.
Looked at and set aside: airbags (1) — 1 airbag complaint on file, almost always a recall matter rather than a repair bill; have a dealer check this VIN for open airbag campaigns and confirm any were performed; the lights (1) — 1 lighting complaint on file; real, but usually a bulb or a housing rather than a reason to walk.
Counts come from the NHTSA complaint and recall database — free, public, and worth checking yourself.
