I'm getting the same sound.. does it happen when you let off the gas as well? Thats when i notice it.. Haven't called Nissan on it yet, let me know if you find something out.

 

I should of read the forum better. I just posted a question in regards to a noise I'm experiencing. I too am getting an odd noise, but mine sounds totally different. It not a tapping sound, but a mechanical sound. Its hard to describe, but it kinda squeaks. The only thing that comes to mind when I hear the noise is like the sound my motor in the side mirror of my old car would make when I would adjust it. It only last for a second or two and only on the accelerating end. It happens like clockwork. I just gun it and theres the noise.

 

i heard a strange, mid to high pitched "tone" that stayed at a fairly constant volume for at least a minute last night on the highway. i noticed it somewhere between 90 and 115 mph. i had turned the radio off to listen for anything strange because it was the first time i had pushed it on the highway. it went away and i couldn't get it to come back. i guess i'll just have to keep the radio off for a while. i must say that it was one helluva ride though. i also pushed it with the traction control off for the first time, it was like driving a totally different car. woowoo!!!!

Try turing on/off your a/c mine makes that noise when my a/c is on. I think its a blower or a motor
