So out of the blue stopped at a light a felt a little vibration on the brake peddle and heard a strange grinding rattling coming from under the car. As soon as I stepped on the gas peddal the noise went away. Next light same thing. Got home put it in park noise disappeared. When I put it back in drive the noise comes back. After a few days I noticed that it only does this in gear "D" or "R" not in "N" or "P" and when rpm are around 500 if I slightly step on the gas to raise the rpm to 600 noise disappears. Anyone have any idea or experience the same problem? Thanks.

That's interesting cause if I turn on the AC the rattle doesn't go away but I can also hear it while I'm in "p" if I shut the AC off the noise stops until I put it in gear.
