I just picked mine up last Friday (8/7/09).

I hear a very faint high pitched sound right around 900 or 1,000 RPMs and continuing up at higher revs, doesn't get louder or softer depending on revs.....hear it whether in Park, Drive or Neutral....and whether all systems (AC, radio, etc) are on or off.

It's very faint but very annoying.

Tech can't hear anything though.....I've read elsewhere of similar problem....has there been anyone else here with this problem?

Any help would be greatly appreciated.
