I have this strange high pitched squeaking/squealing noise that appeared out of nowhere in my Fit (Honda Fit Sport 2011). I uploaded a short video to youtube of me driving it and you can hear it for yourself.

This is the noise:

It happens only when the car is moving, but every now and then it stops, and then starts again. I can hear the noise when I'm pressing the accelerator, and also when I'm not pressing it. I noticed if I hit a bump the noise will stop for a minute. In the video link I attached there is also another squeaking noise when I begin to press the brakes, but this is a whole different noise than the high pitched squeal while I'm regularly driving with no brakes. The brakes do not squeal every time I hit them, in fact they rarely squeal at all.

Are these sounds related? Could the high pitch sound be something not related to the brakes at all, maybe a belt or something? Any suggestions help! Thank you.
