RE: top brakelight works bottom two does
I would check to see if your turn signals and marking lights work in the rear. The turn signals use the same bulbs as the brake lights so the brake light signal goes through the multifunction (turn signal) switch. If the switch has gone bad, the 3rd brake light would still work with the brakes, but the brake lights could be inoperative. Don't know if a failure in the multifunction switch would cause the turn signals to go out, but if your turn signals don't work, then it narrows things down a bit more.
*EDIT* - From a quick look through the wiring diagrams, there is a RH rear turn fuse & LH rear turn fuse in the underhood fuse block. Have you checked these fuses as well? I would start there and make sure that all of the fuses for the turn/brake system are ok.
**EDIT** - Here's another thing for ya:
Your dealer should be able to run your vin (for free) to see if this recall was performed on your vehicle. I believe that safety recalls of this nature are open recalls. If your problem is attributed to the failure as layed out by the recall, it should be fixed for free.
