I have a 2014 and have also notice quite a bit of wind noise from the sunroof. When looking at the roof from the outside, I can see that the back part of the sunroof is slightly higher (maybe 1 - 2 mm) than the rest of the sunroof. I've taken it to dealer once already and asked it to be adjusted, but I don't see or hear any improvement. I will probably take it to another dealer and see what they say.
