Anyone experienced this? It's a loud whistling noise that changes pitch as speed changes, but only makes this noise between 30-40 mph and only in the winter when it's under about 20 degrees, it's not the engine, heaters, windows or moonroof, it drives me crazy! It's loud and sounds like it's surrounding you, I can't pinpoint where it's from, to me sounds like from passenger side but passengers say it sounds like it's from drivers side, I'm stumped -_- I could make a YouTube video of it if need be

OMG, and I thought I was insane! Someone else hears it too! Mine is at exactly 40-42MPH, a whistling noise. My best guess is it's a resonance in the cabin air intake system at that particular speed. I just speed up through it

I would think that one of your window seals is getting dry and when the cold hits it,it's even dryer and contracts a little more causing air to come in and that whistling noise.

But that's just my GUESS

I heard from a couple people it could be the differential, but idk, not worrying now as it's warm and makes no noise, window seal could be possible as my driver window or seal is slightly off, get a tiny bit of wind noise from it

I had that noise all winter and even through the spring time on stock 16's, then i got bigger wheels and dropped my car and haven't heard the noise since so go figure.

Try this: Get some blue painter's tape from the hardware store. Hopefully it will stick at cold temperatures. Start taping up fender edges and door seals edges to pinpoint the likely whistle generator.
