Since you said it went away on its own, ima stop stressing out with the dealer and just let it be for now.
I guess the only sure way to know what it is, is for something to actually/fully break.
Actually, you should take the undertray off and have a look before you assume everything is ok. Just because it doesn't happen when the vehicle is stationary and revving doesn't mean there isn't something contacting when the car is moving and at high rpm.
