I have had two Jeep Grand Cherokees, a 2012 and now a 2014. The 2012 had a leak from the factory and the AC quit in about 3 months. The over the next 6 months the dealer filled it 4 times with leak dye always stating they couldn't find a leak...finally discovered the dye coning out of the heater/AC box drain. Evaporator leaking, big job to replace but under warranty. Traded the 2012 in and got a 2014 with the 8 speed trans (much better). After 3 years (warranty expired) the AC started not working so good. Took it in and guess what...the evaporator was leaking! Service writer said this is very rare...then I reminded him the exact same thing happened on the 2012. With a very surprised look he said he was going to call the factory for help. The factory had me pay $250 and they paid the rest. Hopefully it will last until I trade it in...
