Wish i had an answer, my 14 550xp has done this since brand new, sporatically with no real consistant reason i can pinpoint. Just like other issues with this machine, dealer said, "some just do that, we've never figured out why, but it'll be fine; just shut it off for a minute or two, it should reset itself."
Which it will, then sometimes itll come back, other times it wont. Just another polaris problem thats normal, just like the misaligned clutch mine came with i ended up fixing when two dealers said my issues were normal, and the loss of antifreeze from recovery tank that "just let it leak down, everyone of these has its own happy level it will find by itself"
