System would be barely cool, never cold, then start warming. Did this back and forth randomly. Had date set but about 2 days after scheduling to take it in, then the A/C began to blow hot, only hot air. I immediately called Nissan of Midland service dept and informed them I was coming in, right then while the problem was happening. By the time I reached the dealership ( took about 10 mins) the inside of my car was about 85-90 degrees, blowing hot air with a/c set at 60 degrees, blowing full force. Another part had to be replaced, but was on a National Back Order. But they had managed to get my car to at least blow cool air. I dropped my car off at Nissan of Midland on 8-15-2015 and went out of town. I am still out of town and just received a call to tell me my car was ready. I can only hope there won't be any further problems, but I have my doubts that this car will EVER be clean and clear.

Update from Oct 10, 2015: So my vehicle total has had the AC unit replaced 2 times. The last time was because they found metal debri in the condenser. The annoying whistle sound is louder and all the time. Car still hesitates when accelerating, and AC takes about 10 minuets before cooling. Force of air is still not what it should be at top level. I'm going to unload this POS as soon as I can. I will Never buy another Nissan. Never.
