I would have if it was a PS2 or an Xbox, but I've never heard of a Nintendo system breaking down due to anything but extremely old age, or user ineptness.
Just look at the length of the standard warranties offered by each of the consoles right now, Ninty have faith in their hardware, and want to keep customers happy. Theirs is three times as long as the warranty for the PS2 or the Xbox, same for the Xbox 360 too.
