2005 Outback Display: IGN?

My 2005 Outback did something weird the other day. I started it up and the center display where you can view Outdoor Temperature, mpg, miles until your gas tank is empty, etc., just showed IGN. The headlights didn't come on and the turn signals didn't work. But the 4 way hazard flashers worked. After driving it for a couple minutes the IGN disappeared and everything was normal again. I did a google search and found a single description of the problem. It sounded like the key ignition has a problem possibly from someone having a heavy key chain putting too much weight on the key. And that Subaru had a recall on this problem.  The problem has not repeated itself yet. Does anyone have information on this?
