RZR XP 4 1000 2016 XP4 1K brurned to the ground January 4, 2016 This was a 2016 XP4 1k. 2016’s are not covered in the vent line recall. This makes me think that Polaris either does not know what is causing all of the fires, they are just throwing out the vent line issue to get the CPSC off their back or both.
