I had this issue after 1000 miles, but it had minimal issues on my driving. Now after 7000 miles, the noise had got worsen. Went to dealer to talk about it they say its a Nissan design issue and I called Nissan to raise the issue. Nissan told me the noise was not been able to be replicated by the dealer and they are closing the complaint. I think the dealer and Nissan are working in mutual harmony to deny any claims. I must say and add the issue is not only from side view mirrors, I have wrinkled leather seats (again denied on my face), noise comes from headliner (can't pin point the issues, have to get worst which means it has to fall part before they think about repairing), noise comes from passenger side dashboard (again denied on my face).

These issues were talked over the phone with the Nissan Customer Affairs and they did nothing and closed my case saying the dealers were not able to identify the issues. However, I can still hear the noise from my car.

Well i was driving down the highway and heard a vibration noise like my drivers mirror was coming loose. I took it in for service along with other problems i had and was told the could not duplicate the problem. I was very upset about this because i had read there was a service bulletin for this exact problem. I felt like the dealership drove my car to the lift and looked at my complaints and just gave me standard out of a book answers instead of spending the time to diagnose the problem. So i made a claim with Nissan and brought it back to them a week later. all they did was added some double sided tape to the back of the mirror. I am getting very upset with Nissan and their cheap ways to fix problems in a car i spent $30,000 dollars on.

Update from Jun 4, 2013: Well I took the car back onto the highway for the first time since the repair, and what do you know the noise is still there. I am very upset with this dealer i have been taking it to. Browns fairfax nissan in fairfax, VA. First time i took it in they gave me a very dirty armada as a loaner car, it had sterring problems, and when i went to get my car they told me they could not duplicate the problem(even though there was a service bulletin out about it) I brought it back and they gave me a maxima for a loaner that was also very dirty and had parts to it in the drivers door and the drivers seat fabric was hanging onto the floor in front of me, While i was driving a car was pulling in front of me and I hit the horn and guess what it did not work(and the service manager called me to tell me he had set aside a car for me before getting there) so i almost had a bad accident but i was able to move out of the way. When i picked my car up i noticed there was bad grease prints on my center console and steering wheel, my radio was changed and the bass was turned all the way up(note I brought this in for noises i had in other places of the car so why would they be listening to my radio?) and my right rear speaker is blown, then I find my power outlet cover had been broken off. This place sucks and I do not feel safe in my new nissan.
