I have a 2008 Focus and for the 2nd time in 2 months my battery has suddenly gone dead. Both times it has happened it has died with in 2 hours of the last time I drove it, the battery has never appeared weak, and the car has never been hard to start. The first time it happened the dash lights flashed, and then went blank. I charged the battery and it started right up and no problems until about 2 months later. The 2nd time it happened, the dash lights would stay on, and you could hear a clicking/buzzing sound when I turned the key. Does this sound like a battery issue? Ignition switch issue? Starter? It is the original battery, but like I stated earlier, it never appeared to slowly die, just suddenly dead. Any help would be appreciated.
