My 2007 Honda Pilot make this "BUZZING SOUND" when I first give it gas (between 10-20 MPH) then it goes away. It seems like something is loose but can't locate anything. Very annoying since car has only 3,500 miles on it.It also happens when truck is in neutral. Before I attemp to bring it to dealer I was wondering if anybody on this site had the same experience and if so what did you do. Please Help!!
