I've noticed my car doing that now too. But mine's an 03 with 26K miles on it and I think that I'm just noticing the sound because of all these threads about it. I think it's just been normal this whole time but now that I keep hearing about it I'm hearing the noises, . I have no uneven tire wear though, so no biggie.

 

well, went to Nissan to get my 7,500mile check in...
I told them again about the tire problem (this is a different dealer ofcourse) and the service guy is telling me its not their call at all. Some "guy" comes in representing Nissan Canada/NNA and either tells them to do it or not. And theres absolutely no way customers can speak to this guy.
So I asked him what someones supposed to do in this case? Speak to the service manager? He said theres really no point in talking to anyone if the "guy" says no.
