My 2012 did exactly the same thing when brand new with 8 miles on it. Two things were the problem. The tires had flat spots from being parked in one spot for some time and the rotors were in need of 'cleaning'. They were not out of round but rather had uneven build up of pad material. I am still amazed that the latter could happen on a car with that little mileage but it happens. Frankly, I still find the brakes to be the weakest spot in this vehicle and I think they are grossly undersized. I should have been more attentive on the test drive as I think they could have been a deal breaker.
Also, I am very disappointed in the dealership for delivering the vehicle in the condition it was in. Anyone just taking the vehicle to the gas station to fill it should have noted the issue and had it taken care of before delivery. Also, given the number of reports of this issue I have seen here on the forum checking for build up on the rotors should be standard procedure for this vehicle pre-delivery.
