New does NOT mean correctly aligned. Make sure the lug nuts are torqued down correctly, get an alignment, and check the tires for balance. One of those 3 is your culprit.

I have the same problem. It has been aligned and 3 times balanced (road force). My slight vibration now sits at 80mph.
Each time a balance was done, the vibration changed a bit and was observed at a different mph.

I had the same problem with my 05. I have aftermarket rims and no Tire pressure sensors. 
I have run flats and it is hard to tell if they are low in air by just looking at them.
Well I checked them and they were all off by 10 to 20 PSI. This is something simple you can check if you haven’t. I pumped them up to 30 PSI, problem gone.

Might also be a bad/damaged tire.
Anyway, torque the lug nut to 100 ft-lb ASAP!
If that doesn't fix it, take it to a local dealer... doesn't matter if you bought it somewhere else, any Chevy dealer should fix it at no charge under warranty.

Although not a bad idea to set the alignment up for the way you are going to drive, it's likely not related to any vibes. I'm convinced that a certain amount of vibration even after tires are road force balanced and maybe even replaced if at the wide end of the range is possible. I think it is somewhat inherent in the stock Goodyear run flats as well as other low profile stiff sidewall tires. If a vehicle is sitting idle for some time, it seems to be more evident but lessens after driving a bit.

Correct, I still have it. It is minimal, so I decided to live with it. Too many trips to the dealer and a messed up wheel. Although, they did warranty the wheel. But even after that, still couldn't get rid of the vibration.
I will try again once new tires are needed.

Add to the list of possible culprits brake rotors being out of round. With my two GS's both needed alignment and road force balancing of the tires, one needed a tire replaced that was out of round, and the other needed brake rotor replacement. If you have a good dealer, they'll eventually get it right -- it's warranty work and parts, and they want to make you happy.
