Humming/Buzzing Sound HELP!!!

[nickA1022]

Hello all, new to the forum here. I just recently purchased a 2011 nissan altima coupe 2.5 s. A couple weeks after the purchase i have been noticing a strange buzzing/humming noise. This noise is extremely noticable during a cold start up of the car. I also notice that the car makes this noise at around 1700-1800 RPM consistently weather i am accelerating or decelerating. I have been doing a bit of research on this problem and it seems to me that there might be something wrong with the CVT? Can anyone please send me some feedback for this issue before i actually go to the dealership to have it looked at. Any kind of response would be much appreciated.

I recently had what sounds like a similar noise I thought was coming from the CVT on my 2.5s '10 coupe. Still under warranty, I took it to the dealership & to my relief & surprise it turned out to be vibration caused by 2 loose or broken clamps. Parts: $3.90; Labor: $6.00- w/NC for either. total: $0.00. I hope your issue turns out as well. good luck!
