Air Noise During Acceleration

Does anyone else hear a wooshing / hissing air noise coming from the passenger floorboard area during mild to heavy acceleration or engine load?
It gets louder with throttle input, not speed. Is this normal or could something be wrong with my air intake?

Our 2015 Sonic with the same motor doesn't make this noise.

This is a brand new 2016 Trax LTZ AWD with less than 200 miles.

Hissing noise

I notice a hissing noise our 2016 LT. I thought it may have something to do with the A/C compressor recycling. At some point I'll turn off A/C to see if hissing stops.
Has anyone else noticed this??

After my A/C is on for awhile (in recirculation mode) the sound of the fan changes, like the blend door opens or something. I wonder if the noise he hears is turbo whistle, but I don't hear it on mine.

Hm.. I mean if it's significant enough to where it's bothering you, definitely stop by the dealership and see what they say ? I'm sure if it's a constant thing, re-creating it won't be an issue with a service technician.

I would check the firewall, look for gaps where hoses and wires enter the cabin.

Thanks guys, it's definitely not coming from the AC; it happens with it on or off.

From the replies this sounds like this is not a normal sound. I will have the dealer take a look at it.

I have a similar issue. I can hear the whistle sounding noise sometimes but I definitely hear it in when i use the brakes. It sounds like air blowoff so I think there is some sort of leak in the intake or exhaust system.

This issue paired with the lack of A/C working has me very disappointed in my Trax decision.

Seems as if many owners of the Trax have an A/C issue. The A/C works fine in my Trax, but I will admit that I have heard the hissing noise everyone else is describing. It seems to make the hissing or flapping noise when I accelerate.

Wonder if the door seals aren't tight so some of that wind noise is getting though when you accelerate?

That's a big possibility too. Check around the firewall for those rubber blockers or grommets
