1yr and 1 month after I snow checked my 850 NA Matryx my sled showed up late April, took it for a ride and got 10km on it before check engine light came on and limp home mode kicked in. Code is erratic stuck throttle. Since then it has been back to the shop 3 more times for a grand total of 29km and sled still isn't fixed. Now all the snow is gone, so I can not try out the newest fix until next season which is usually late Nov/ Dec. Dealer has done everything that Poo has told them to do. My dealer has been great in dealing with this by the way. Anybody else gotten the shaft?
