Mine leaked when I first got it. Checked all the fittings and found one that wasn't seated correctly. Check all your connections and make sure the collar on the fitting popped all the way back.

Detailed insts on making them seal properly:
There is a little trick to these fittings/air lines. Push in the release and remove the line. If there is any dent or imperfection in the line cut it off with a sharp razor knife. Push the line in while pushing in on the fitting release collar, when you feel the line is all the way in while still pushing in on the line pull up on the release collar with your fingernail. When the collar comes up and feels like it is locking in pull on the air line while pulling up on the collar,you will feel it lock in (don't pull so hard you break the fitting).

Mine was leaking in my 2010 limited. I would loose 8 - 10 psi a day. Took to the dealer and they replaced all the lines. Now I loose 2 -3 lb a week. I can adjust it once a week but not twice a day!

All the quick fixes have been suggested, but I will add that you should never have to check air shock pressure very often. I never had any pressure loss, but then again I never went above 25 lbs. If you choose not to go with Ohlins or Ricors, then I am a big believer in changing the shock oil to a heavier grade. There are a few threads on that.
