Been getting this weird metal on metal rattle sound when at part throttle or sometimes idle. The transmission doesn't have to be in drive to get this sound either. A quick shot of gas while in park or neutral and the sound is there. Has anyone else experienced this...if so did you figure out what it was? I tried to videotape the sound but all my camera picked up was wind noise so it was a bust for video. I brought it back to the dealer that I bought it from and they couldn't replicate the problem. It only seems to happen on dry days...rainy days the sound is gone. Don't make any sense to me.
