High pitched noise ????

[bzizziv8]

I noticed a high pitch noise when driving my 05 sport anyone else hear this sounds like something electronic.My wife noticed it also.
Even with the radio off and HVAC off it still does it.

Can you please be more specific as to where you think it may be coming from? Does it sound like it eminates from the engine bay or cabin (from your HU or speakers perhaps)? Is it audible while the car is idle (with the key in the ACC or ON position)?

Check your engine bay for:

A cat trapped on the serpentine belt.

If so...

Do not attempt to remove cat without gloves.

ohhh yes... turn off engine before removal!
