I had 800 miles on my 2018 Textron havoc. I have not abused this machine what so ever. I was driving and heard a loud cluck in the rear. Checked machine and oil was dripping out of the rear differential. Drove it 100 yds, to my house and parked it. Called local dealer and they picked it up. Upon inspection they said my rear differential cracked and metal shavings were evident. Of course my warranty was over at the six month mark. It was a $ 3800 expense to replace. They were willing to give me 10% off but Arctic cat would not help in replacement costs. Remember I had only 800 miles on my machine. Tried calling Arctic Cat myself but nobody answers or calls back.
