I'm having problems with the shifting from FWD to REV again but only after it gets warmed up. I emailed the dealer and he's checking on a new clutch they are now using in the 2013 550s but the part is not available yet. This is in place of the new clutch replacement of a few months ago. I hope this clutch fixes it. As far as what I think of the 550 XUV it has all the power I need, great riding and I would buy it again (if all problem are resolved). It's nice looking and $10,000.00 cheaper than other 4wd off road toys. I believe JD has most of the bugs out of the 2013s. I just purchased it too soon. I knew since it was a new concept for JD it would have a problem or two and they are fixing them. Just not as fast as we would like.
