Trouble with new c7?

Bought new 19. Auto, 2lt. Noise coming from rear since new. Back to dealership tomorrow to see what's up. Taking mechanic for a ride.

Sorry to hear that. Not sure if this is your issue but many people on the USA forums talk about the warble noise coming from the rear end. I think generally it requires the differential to be replaced. I personally just had my diff replaced but it was due to a bad seal that is also becoming an issue with many vette owners especially at the 30km mark.
