I own a 2010 550XP and have had fairly good luck besides it shuts down on it's own 3 or 4 times the 1st time you attempt to start it, sometimes won't start at all once it gets warmed up, and the exhaust gets so hot it has melted plastic around the seat all with 170 hours on it. Still I really wanted a side by side & thought I'd stick with a USA based manufacturer. Like an idiot I didn't test drive the machine I purchased, literally unloaded it & drove it a mile & it was vibrating like the thing was going to come apart, brand new mind you. I text the dealer & they say check this check that & then come back & say oh yea we have a bulletin on those. A bulletin 1 day after I paid $21594 for a brand new machine. I guess I should have woke up when the stickers were pealing off while I was loading it up on the trailer at the dealer or when we could not get the hood latched because the thing is so poorly engineered. The more I look at it the more I see it's junk. Unbelievably disappointed and frustrated!
