Simply because now everyone is playing Smash Bros. like mad. More consoles being on for longer times equals a higher chance of factory defects popping up. Your search query strengthens the hypothesis (but does not confirm it).
Basically yes, SSB is for sure the fastest selling Wii U game to date, this means, it's put in the hands of more players at a shorter time frame, then any other game before. An error possibly occuring with every game (or at least with a high number, if you look it up on Google) is expected to occur more often with a game, that sells better.
