Still having power loss under hard acceleration. Reflashing the computer fixes it for a month or so.
Cracked ring land on the number four cylinder. Subaru found Youtube vide of me at an autocross event and denied warranty. Replaced on a good faith with a $1000 deductible. This was after two months in the shop. Never buy a Subaru again!

After 3 trips to one dealer and a Subaru Engineer telling me there was nothing wrong with my car I finally took it in and another engineer said I had a cracked ring land and Subaru would not fix it under warranty!
Subaru claimed car was modified which caused cracked ring land and after 3rd party and another Subaru dealer verified it was not modified Subaru still refused warranty work - Either rebuild the engine myself or sell the car!
Engine rebuild out of my pocket ($8000) because Subaru has a design flaw in the piston that causes the ring lands to crack. This will happen even if you have not modified your STI so beware. Engine shop said this was VERY common in STI's.
Took car in days after software reflash. Check engine light was on, car vibrated upon ignition. Took it in to deal. Mechanics left dome light on causing dead battery. Codes were lost. Couldn't find problem after battery died. Lost all codes.
