My rzr has been in the shop for a month for a misfire code, 65590 and 65592. This from what I have read is a common issue with several polaris machines. My dealership said tech support tells them to replace the belt and still not fixed.I just paid $350 dollars to not have the problem fixed. Polaris needs to step up and do a recall and reimburse customers for money spent. From what I have read and head from dealerships the ECU is to sensative on detecting misfires or false misfires izi should say. I will be out around $800 dollars after having an outside company address the issue. It is sad that a company this size does not care enough about their customer to make this right.
