What I've done
I've already been to the dealer once and we thought it was the throwout bearing
so that was replaced, but, the squeaky noise still appears. It's intermittent but I think it's been happening more frequently this week. Whenever I bring it to the dealer they are unable to recreate the issue (of course). I have an appointment again on Monday in which I believe they will take my car for a few days and have a manager drive it. Hopefully it makes the sound when I show up this time so we don't have to go down that route.
Here are some more in-depth symptoms
The sound is prominent while the clutch is disengaged and I am under 3k RPM.
When I engage the clutch (even just tapping on it) the sound disappears.
When I rev the squeaky noise turns into a spinning squeaky noise and then disappears around 2500 rpm.
So far I think it could be the Pilot Bearing

One of the posts in there has basically the exact symptoms that I do, the poster at the time of this thread was KurtRadin
