 Had the car coming up on 1 year. I have 6400 miles. The 1st week I owned the car driving 80mph down the expressway the power steering went out. The car had to be towed to the MB Dealer. A month later the sunroof would not close (it started to rain) again back to the dealer. 5 months in the sunroof broke again. This time I told the dealer last straw fix this thing or take the car back. Tomorrow I take it in again for a knocking sound when you turn. Also the sunroof is now once again broke. Previous I had a E-350 and had no problems. This 2015 C-300 has been a huge disappointment. For the money MB commands this is just unacceptable.
