i had a few problems with this issue. As soon as i heard it, i went back to subaru, talked to the head tech at Dockland, i think his name was Michael or something and he immediately knew it was the clutch. He promptly went into the office booked me in for the next week and ordered a new SMF clutch assembly. This was all undertaken under warranty, and i have heard of this problem also being fixed out of warranty.
Best bet would be to take it to them and see what they say, because it is a common issue.
