Squeak Under Hood - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

I've noticed a slight squeak recently under the hood of my 2011 SS LS3. Car has 27,000 miles on it and the squeak started about 2 months ago. It doesn't make the noise when the car is cold and warming up. I start noticing it after 20 minutes of driving. Additionally, it seems to be more noticeable after I go full throttle for a short time.
Once the car cools down, I don't hear the squeak until I drive the car for a while again. It seems to be coming from the driver's side of the engine (possibly the power steering, alternator, or idler pulley).
Has anyone experienced something like this? Any TSB related to this? Thanks in advance!

Are your belts too loose or too tight? Are they glazed?

Belts look good and have good tension.
I should mention the squeak is loudest around 2000 RPM and squeak rate increases/decreases with the engine RPM.

Sounds like belt/pulley noise to me but impossible to tell without being in person or at least a video.

get a stethoscope

and are you still under warranty?
