I just purchased a 2007 Vibe and it is making an odd noise. It is constant, though it seems to vary a tiny bit with RPM. It is very noticeable in the car, but not outside the car or under the hood. So, I thought I'd post a video and see if anyone could identify it. It's sort of a whine/howl? It's quite loud, though it is a little more pronounced in the video than IRL. My best guess at the moment is the belt tensioner pully is going out, but I figured I'd throw it out there and see if the hivemind had any other suggestions before I go chasing this wild goose.
Anyway, here's the link and TIA.
