on my G37s. Sounds like there's a window open somewhere. It's that same kind of pulsating noise, but I don't see anything open.

Any ideas out there?

What speeds are we talking about here?

 

seem like pretty much all speeds. no noise when stopped, just when moving. Don't think it's tires. Just have no clue.

sunroof? maybe if you uploaded a video of the sound we could help, this is pretty vague description.

 

Have someone else drive the car while you sit in the back seat and listen for the sound as you know exactly what you're listening for. The noise will be amplified much more if the ground is wet while driving. Usually a door seal or window seal is the culprit. You didnt say if it was coming from the front or rear. I've noticed in older cars ive owned that sometimes the door glass pinches the seal upon rolling up the window like when parking the car for the night. The glass creates a permanent groove in the rubber, and it can sit like that for long periods of time undetected. I've also had situations where the glue at the corners of the windshield either rotted or dried out causing a light whooshing/whistling sound at highway speeds. Another area to inspect is the sunroof. I've seen a drop or two of water drip down from my roof in the carwash when its being blasted by high water pressure. If your G is under warranty, I'd just have the dealer check it out and let them go crazy replacing stuff for free.
