Some Funny Noises - Concerning? (audio clips)
The first clip was recorded during brisk acceleration in 2nd gear.
Although somewhat difficult to hear over the wind noise, you'll notice a brief squeal right before I shift into third.
The second clip was recorded at a stoplight this morning, while the car was at rest.
The acceleration squeal has almost always been present, unless it is very warm outside (hot summer day).
I don't always push it hard enough to hear it, but when I do, it's there.
The second noise has only developed this winter. Usually it occurs only briefly, and only when I come to my first leisurely stop at the end of my street. Today was the first time that it's occurred for a prolonged period, and while the car was warm (I'd already been driving about ten minutes at that point).
So, what do you think ladies & gents?
Cause for concern?
Not a big deal?
I should note that the dealership techs checked the belts and tensioners recently, apparently everything looked fine.

It is very hard to say without being there in person. Google/ YouTube supercharger prop shaft bearing / isolators faults and see if it’s a match? The belt squeak could be several things, need a new belt, tensioner, or it’s wet, damp or dirty. What motor and miles on your cat?
I have read it occurs more often when the temps are very cold outside which causes the isolator to fail or chatter.

I had this same issue. Belt looked fine, plenty of tension. No issue initially when warm out, only when temps got below 70 degF, but issue eventually got worse extending into warm weather. Belt needs replacing.

I couldn't hear the squeak in the shift mp3 on my phone.
