My '08 did the same. It seems to do it less now.

 

If it squeaks with you depress it, it could be the slave cylinder. It starts when it gets wet and will never really go away. Had it in my 09

 

same problem here too... always bugs me when I'm driving, but then I always forget to look at it when I get to the house... maybe now I will get down there and take a look

 

I had that on my 2012. Basically it would squeek when the jeep warms up. So if its warmed up and you press the clutch, you would hear it squeek as the pedal moves down, once you release the clutch slowly, it would squeek again.
Gave it to the dealer and it turned out to be throwout bearing. They had to take the tranny out and order the parts. Took almost a month :( On a bright side, had a loaner with auto start and no more squeeky clutch.

 

I was having the same issue. So I climb underneath, and had my wife push the clutch peddle in, and whahla, the linkage was rubbing the floor board heat shield. I bent it a little and no more sound.
So I hope you work was done under warranty.

 

Finally took it to the dealership today and they said it was the clutch master cylinder. Has to be replaced. 3-5 day wait on the part
