It can, it is a cheaply made product. However sometimes it depends what SD card you are using, if it is Japan or Taiwan. In certain games it'll freeze if it is taiwan. Also SD cards sometimes ship defective, I have on mini-SD at work that makes anything lock up that it is inserted in.
Just because it's cheaply made doesn't mean it'll die on it's own.
I'll restate it again. Get a new MicroSD.
