It didn't do it every time, only sometimes, and never for the dealer. Finally it went all the way out and stayed fully engaged. That is when the dealer finally replaced it. No more clicks since then.....finally.

Good point mark!
Check this, it is a really common issue and one that can be fixed for ~$350 tops if you have the dealer do it out of warrenty. I know it isnt the clutch on mine, as right when I start it the clutch locks up and spins really fast for 2-3sec like it is supposed to and then quiets down. Another big sign of the clutch going bad is really bad mileage and a jet-engine woooosh coming from the hood.
