2005 Subaru Impreza WRX STI — Should You Buy One?
Typical asking price: $18,000–$40,000. There is 1 high-severity known issue you need to know before handing over a check.
Kestrel Take
The Evo's arch-rival — the EJ257 boxer, a proper six-speed, and rally-bred AWD. Same story: bought to be modified, thrashed, and sometimes crashed. The EJ engine's ringland and bearing weaknesses punish bad tunes hard. A stock, clean-title, unmodified STI is the one worth having.
What we checked
Partly reconciled against public records, 2026-09-25
NHTSA holds 75 owner complaints for the 2005 Subaru Impreza WRX STI, and 6 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. The largest single group is the fuel system at 25%. That is notable without being overwhelming — worth checking, not worth panicking about.
6 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 fuel system (19 complaints), the suspension (17 complaints). 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.
Looked at and set aside: airbags (12) — 12 airbag complaints 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.
Counts come from the NHTSA complaint and recall database — free, public, and worth checking yourself.
Known Issues for the 2005 Subaru Impreza WRX STI
Ranked by wallet impact. These are documented, recurring problems — not freak accidents. How we decide that.
The boxer engine cracks ringlands and spins bearings under aggressive tunes, detonation, or neglected oil. Verify the tune, compression, and oil history; an unknown-tune car is a real risk.

Source: NHTSA complaints filed under the engine (8).
Most were tuned and driven hard. Verify build quality and engine health.
Repair cost: Not a repair — an ownership-cost warning, not a mechanical fault
Source: NHTSA complaints filed under the engine (8).
Crashed cars return with washed titles; verify carefully.
