I bought a new 2015 sportsman 570 eps efi 082215. It had less than a mile on it. I drove it to test it out. I had put 3 miles on it. On 090915 I took a trip to San Isabel, Greenhorn Mountain and rode it on trails . We stopped for a rest and noticed the center of the left rear tail lens had melted. I called the dealer service department and the tech told me they have only had one other do this due to leaving the brake on. I advised them I used the engine braking mostly and it should not have happened. They are covering the replacement. There is a history of polaris atv tail lamp/lens heat problems. With only 33 miles on it this thing melted. The consumer product safety commission has other cases of similar problems. Buyers beware! I wonder if they have any intention of fixing this serious issue!? Ridiculous.
