Recently I have been hearing sound in the center of the dash which sounds similar to a turkey gobble. It is intermittent. Often heard right after startup as it idles in the garage. Only lasts a couple of seconds. I am certain it won't happen when I take it in to the dealer.

 

Cold serpentine belt making noises? Open your hood the next time, and then start it up. Get out of the card and see if you can narrow down the location of the noise.
