Mine is a 2014 with 1500 miles. These seats are very thin, which might make it hard to attempt to repair. I talked to the guys at Seat Concepts and the 690 seat is one of the seats they will not recover and you have to get a whole new pan (if you want one of their seats).
Mine was replaced under warranty, which is now expired - hopefully the new seat will last a little longer than the first one!
