That's Microsoft for you. >.>
Anyway, no console just 'breaks' unless you are overusing it like leaving it on for a couple days or even weeks straight. Otherwise, it can only come from:
A - Opening up the inside of the console which immediately disregards the warranty.
B - Dropping it on the ground, instantly shattering it on the way to a friend's house.
or
C - Getting so excited while playing a game you yank on the controller while your watched your beloved console fall 1 foot or so off of the stand/table and hit the ground.
My feelings. ^
