Melted Cargo Box

I’ve been extremely happy with my 570 Sportsman but I had an issue with the heat as everybody on here seems to be talking about. My exhaust actually melted a hole in the cargo box/trunk!! A little grass/mud got piled on top of the exhaust (it’s in the wheel well…..) and got hot enough from the exhaust to burn right through the plastic right where the exhaust attaches near the box. It’s been a week and still waiting for my dealer to call and let me know if Polaris is going to warranty it.
