We're in the midst of our first 1500 hr, If you have any warranty left, check the rotor brake splines under the rotor, ours was worn to the point the splines are sharp. and the output section of the transmission now needs to be replaced. there is a new style rotor also, so get it installed or you'll be buying one also.
Also we found a crack in the stainless firewall panel above the inlet where the bend is, it follows the bend so its hard to see, also the blue stiffener at the top was broken where it attaches to the vertical blue piece to the right of the particle separator, you'll find smoking rivets under the engine pan framework that the through bolt and spring attaches, its common I hear.
