That's highly unusual. You should ask yourself what peripherals/kernel extensions/weird software you have installed that maybe contributing to this. And I would definitely bring it in to Apple for service if the answer is "none."
My previous MBP went ~2 years of very heavy use without a single crash, and my 2012 MBA has only crashed once, right after I installed google hangout stuff.
These days I use VMWare, but I've got co-workers with Parallels installed and all day everyday they have random kernel panics and crashes. Uninstall Parallels and most likely all of that stuff will go away...
I had an issue similar to this that was related to a hardware problem with the GPU. I took it into the apple store and they ended up replacing the logic board.
