Thanks for the feedback. Its now day five. Since the car is brand new they are obligated to find the source. It is being handled as a pre delivery issue. As you can see it has factory installed upgraded wheels which is why I thought it was a wheel balance issue. The dealership said they want to make sure its not anything else because it's rare a car is shipped from GM with a balance issue. I am happy they are being careful but I barely had it a week. The vibration happens even after a good warm up and at all miles. The tires are all nitrogen filled.
Life begins at 4 am... for me that is.
