My 360 has a warranty, but what about my controller?

The controller that came with my 360 is starting to have problems...I think.

The right analog stick is the problem. When I push it in one certain direction, it stays there, not returning to the center. It is not that big of a problem atm because the analog stick is easliy put back to the center where it belongs. However, Im still wondering if it will get worse, to the point that it will effect my gaming. I was playing Gears last night and I didnt have any problems so it cant be that bad.

So, my question is, Does the controller that comes with the 360 have a warranty?

I doubt it, but $50 for a new controller is a lot of money if this controller goes south

Also, Id like to metion that I have only had the controller and 360 for about 7 months now. I thought my controller would last longer than that.

Sorry if post was to long:P

Thanks for the help
