I have the same clutch smell and stutter at 1st gear take off. But mine was after some sand action. I also forgot to turn of the traction control.
I hate that button! I did give the under carriage a good "hows ya father" when I got home.
Only 2K on my '12 JKU, going to bring it to dealer, hopefully they will replace clutch (it is warrantied to 12K miles).
