My new car is making noises? Update?

I purchased a new Honda Civic 2015 about two weeks ago. Recently I have been hearing a grinding noise when I slowly press the brakes. Also, when I first start up and switch from park to reverse I hear a grinding noise. I'm certain that it is the car changing gears. However, I haven't heard this in any of my other previous cars (Chevy Cobalt 09) . After all of this I took it to the dealership and he said it was normal. The break noise is caused by the "breaking in" period, and the gear shift is apparently normal and will never stop because the car is cold. He said that the brakes need to mold to something or the other. Is this information true or should I go and hassle them some more? I paid big bucks for this car and expected it not make disgusting grinding noises, please don't kill me for being picky! Haha.

Update… Car is at about 450 miles and the brakes are still making noises, and the transmission is still making a grinding sound when I switch from park to reverse (occasionally.).

Any suggestions? Would I be eligible to return this hunk of junk for another new car?

If I had that problem with my brand new car, I wouldn't be asking about it on here. I would have already been at the dealer I bought it from telling them to fix it or get me another car.
