There was a recall on my car back in Mar 02 2004 (Ford recall number 04s12) for an exterior lighting:brake lights:switch, which was (according to Ford) done Jan 10 2005. I had failed again on 11/15/2012 leaving me without brake lights and not being able to get it out of park. Had to put it in neutral first before I started my car so I could drive it to get fixed.
Brake light came on, replenished brake fluid. Service center found rusted brake lines under vehicle- replaced them, on March 8th.
