Everyone is experiencing the same problem. The alingment is off. I hope that in your case the toe is the only issue. In my case everything is off (camber,caster, & toe) and as I have found out the camber and the caster on our cars can not be adjusted. This means that the whole front end needs to be changed. The dealer I am working with at fisrt tried to blame me for the damage saying that I hit something. After a few short strong words and copies of the pages from our forum on technical problems he quickly changed his mind. I have since not had problems with the dealer but Nissan of north america has be slow to accept the responsibility and I have even caught them lying. I have two other friends in our area that I know of that are have the same noise at low speeds, it is deafening. There is a possibility that during ocean transfer of our cars that they stressed out our aluminum parts just by a few degrees. The warping is not evident by visual inspection you need to take your car in immediately and have the dealer mount your car on the alingment machine. Also turn your wheels right or left and check the inside edge of your tires, I canassure you that the uneven wear is present and you can even feel the notching of the rubber. The uneven wear is what is making the noise. I would request alingment and new tires. Each tire is $310, don't wait act now. Good luck and remember that NNA service will suck!!! I love my car but I think this will be my last one next time Porshe.
