Ugh, just dropped off my 2011 WRX, with only 2k miles for service. In between shifts, particularly at hard acceleration between the first three gears, I hear what can best be described as a scraping or creaking sound. Almost sounds like a loose trans mount. I'm also going to have them check about a hesitation around 3k rpm that feels a lot like a slipping clutch.
Haven't had the car a month and hate to give it up for even a day!
