Finally after dealing with this aggravating noise, I decide to take it in to the dealership I purchased it from only a month before. Of course the mechanic tells me that he couldn't hear the noise, so I took him on the highway and after a short time and over 70 mph, the noise begins. It sounds like it comes from the AC vent on the passenger side, but of course I'm told he cannot figure it out and for me to drive it for awhile and have it recorded so he can listen to it in more detail. Now, I am trying to figure out if I should remove the AC vent myself or take it back again so they can do it, since it is still under warranty. #aggravated
