In short (no pun intended..) ALL stators go out. It's one of the reasons they only have a one year warranty. Usual mileage is probably 20,000 or so or two to three years.
However, most other stators are easier to swap out. That is the one thing that makes our stators a PITA.
There arer exceptions. Reports of bikes with 80,000 or more miles on the original stator. Most of these get regular maintenance, don't overheat and do not tax the electrical system. Even with that, there is no gaurantee a stsor will last forever. They are made by humans after all.
BTW, I also wanted to mention that if the voltage straightens out once the bike warms up, chances are it's NOT a stator problem. One of the problems is a short to ground AFTER the bike warms up and you would see the voltage drop to 12.5 or there abouts.
