HI
Ive had my foxy r 2011 for 4 1/2 years. The frame is still going strong and no issues at the moment. I did originally have a few problems with pivot bolts coming loose and then rounding off when i retightend them. mondraker replaced the bolts under warranty for a steel set which have not caused any issues since when fitted with lock tight.
I need to replace the pivot bearings annually but I suppose that varies with amount riding you do/conditions and is the same for any full suss.
After the initial teething problems its been a great frame and still rides very well.
My guess would be that once you have replaced all the bearings it will be sweet
