Must have been there when I bought the car from the dealer new, it had 150 miles on it when I took delivery and I noticed the issue almost immediately the first week I drove it. Vibration on steep hills and slowing from highway speeds. I am in my 50's and have had many cars. Many break ins I know how to break in a new car. There is no reason for this car to have new rotors scored like this based on anything I did as a driver. I have never had a new car have this kind of problem. This was not normal. Don't know what caused it but it was nothing I did. Very easy driving and easy on the brakes. I don't know what happened but the dealer quickly agreed and replaced the rotors with new ones.
