I have a 2017 Maxima Sr (Midnight) and I have noticed a hissing sound when accelerating from a low speed(5 mph) to about 25 mph hour. I have had the dealership take a look at it and they said it’s normal “road noise.” Has anyone else noticed any sounds when their windows are rolled down? Should I be worried about this? The sound is really annoying and I’ve never heard something like this in a car before.

 

Hissing sound is wired, when the windows are down. They tend to have this hissing sound on highway speed.

 

I have this occasionally - and believe the electronic noise cancellation system occasionally acts up.

 

Is it hissing? I have humming noise... happens rarely though.

 

Funny thing I hear hissing too. It was 2 things. The heated/cooled seats when they were on, and the poly seatbelt tag rubbing on the seat.
