Angry 2011 Sportsman 800EFI (POS?)

In April of 2011, I bought a new Sportsman 800EFI. I bought it mainly to plow snow in the winter, but also for enjoyment otherwise. I haven't taken it anywhere but local logging roads, and have never ridden it hard.
When a headlight went out after two months, (less than ten hrs) I knew bulbs can be defective.
After about 15hrs, it started hesitating in reverse, but was fine otherwise. Then, after less than 20hrs, the battery wouldn't hold a charge. When I finally used it to plow (about 8" of snow in our driveway which is about 100yds long), it began sputtering and running rough. Then it finally wouldn't idle. Also, a battery charge lasts about an hour.
Now my new quad, which should be in for initial service, is going to cost $600 minimum for a sensor that the dealer says "we've never seen that go bad before". And they still haven't addressed the battery issue.
I hope this isn't normal for Polaris. I'm pretty pissed, particularly since there's no real warranty coverage. I'm thinking I should've gone with a Yamaha... I may cut my losses and trade it in before it really starts costing me money.

How long has this machine sat without being actually ridden around?

Batteries die really fast if they aren't used. Fuel goes bad in a few short months just sitting there. Might be, or might not be the problem.

Polaris is definitely not a bad machine, those Yammy's suck, they are 3 wheel drive for pete's sake.. My old 800 was a beast and pushed snow all day if it had to, sounds like you just got a glitchy one and that should all be covered on the warranty...
