The statute of limitations does not apply in this situation.  The SOL has to do with the time in which you must be charged with an offense, however, you were already charged.  Accordingly, it doesn't matter how much time has passes.  Additionally, once you failed to appear (FTA) on your court date, the judge would have issued a bench warrant for your arrest.  What you need to know is to hire an attorney where all of this occurred - ASAP.  They can best represent your interests.  Remember, you not only have to deal with the FTA charge but the underlying charges as well.
