The issue results from an imbalanced drive shaft. With the camaro, it was cheaper to just replace it than find a specialized shop to attempt to rebalance the existing one.
The hum was very pronounced and felt in the seat and throttle pedal. It wasn't a consistent hum, even at consistent speed but rather one that built up, then declined (sine wave?).
If the car is under warranty, keep pressing the issue. Go with the tech/service manager on a test drive to point out the issue. 62 Mph is not speeding so they can't use that as an excuse.
Have them swap wheels with supposed quiet tires from a q40/50 to your car, drive it, does it still make noise?

This noise has followed three sets of tires. Either it's my rims (which the balancing at the tire shops would have shown excessive run out, etc) or its my car.
I'll have to schedule a visit with Infiniti.

Spoke with the service manager and explained the situation. He promised to take care of the noise. He was going to assign someone to it, let it roll with the wheels off the ground, etc. I mentioned a possible imbalanced driveshaft (or 2 in my case). I'll be dropping my car off and picking up a loaner on the 26th.

I was surprised to hear your original Conti's were noisy. I know they're not the same tire, but I have the ExtremeContact DWS 06's, and they've been great all around. Even the tread looks less aggressive. I'd post a pic but I'm having some issues in that dept. lately.

Anywho, I got a call this morning from the service writer telling me the technician couldn't hear the noise. (He also quoted me as saying a high pitch whine when that's not what I said AT ALL).
I went up there and rode while the shop foreman drove. As soon as it hit about 60, before I could get the words out, he said I hear and feel the noise. I almost hugged him :lol:
He said since its AWD, it's likely the front driveshaft u-joints binding, as he's seen this before. He said they were going to replace the driveshaft with a new one and see if it stops. He said if the noise is still there, he will continue his search.
Just an update so far.

Front driveshaft was replaced. Much smoother and quieter now.
And these Pirellis really are some QUIET tires, as well. The Q50S was like driving with rocks as wheels. After driving it though, I will be getting the paddle shifter kit for my G37.

I'm not too upset about it now that I've been able to compare the Pirellis to the Continentals. I'll be going with these Pirellis in the future. They're much more refined in ride quality.
Got to joy ride a Q50S in the process, so all is well that ends well.
