scrambler 1000 issues

Not impressed with polaris quality. My brother bought a new 15, not even 50 miles on it and he snapped a front cv shaft in what we consider mild mud with stock tires on it. A few weeks later were on a ride and he blows a tire on a rocky trail. He said it felt like his rims were bouncing off rocks the whole ride, we checked the other three tires and all three only had 2psi in them, now I know this is something we could/should have checked right away but being brand new assumed tires would have been checked on pre delivery inspection. After this we bought an aftermarket snorkel kit to play in some deeper water, on our first ride it sucks water into the belt housing. I assumed we missed tightening a clamp or something. Nope it was leaking into the belt housing where the belt housing is mated up to the transmission, a factory sealed location. Not impressed at all.
