problem details
My 2011 Nissan Mixama is making a knocking noise while idling. I have taken it to 2 different dealer and they say it is normal. My wife has a 2011 Maxima and it dosen't make the noise hers have close to 6000 miles on it
I hear it too; I now have 42K on mine and it doesn't seem to be getting any worse. M son's say they think its just noisy fuel injectors, but time will tell. I have had so many problems with my 2010 Maxima that I will NEVER buy another Nissan product! (see my review on my 2010 under screen name Charleee)

My noise is only when the car has been running for awhile, it's a low knock at idle that follows the rpm level then stops when driving. Took it to the dealer and they told me it's a common problem with the main bearing, there trying to get me a new block.
