9 months & 9k miles on my '12 135 vert.
Various creaks from time to time but not horrible and I just write it off because its a convertible.
A couple weeks ago the plastic power seat controller seems to have broken. It still works but I'm still under warranty so I'll have it fixed next time I bring the car in.
Other than that no issues.
