im proud to report to you that I got a new seat..
I have 2012 f30 with regular Dakota leather, the stitching on the side cracked where the leather is attached. I was a bit surprised, maybe my but is too big for bimmer. im only 220 lbs. omg.. But its whatever, I got a new seat and it looks primo. Well except the giant scratch on the opposite panel.
Dude at the dealer said this was a common thing, no questions asked.
