I just discovered this new sound in my car... 2001 3.2L S
It's coming from the back and I have no idea what it is.
It's the whinny noise at 2 seconds and at 9 seconds of the video.
The 9 second one is better.
My phone captured it well but the upload kind of made it quieter but you can hear it if you listen carefully.
