Another new RZR up in flames

Just heard from my neighbor, a wildlife officer, that he was involved this last week "with another Polaris UTV Fire". No gas can, brand new, first time out with new machine. Apparently, not the first he has had involvement with. After seeing one go up in flames in person for no apparent reason a few months ago, it is now in the back of my mind every time I put my 3 young kids in to go riding. It seems like even though it may be a very small number in comparison to the total number of units sold, but it must be something the manufacture is aware of. Does the fact that there has been no recall mean that either Polaris doesn’t know the cause and fix, or they are choosing to not acknowledge there is a problem?
