I have the LX and haven't had any problem at all, I just leave it on Auto and have the temp's set at 73 degrees. Out in the sun, I just hit the Start and the air comes on and with in 20 seconds it's blowing cold air. I've did this and not move the car and the air will run maybe 10 min's before the engine ever starts and the it will run maybe 5 min's and turn back off for another 10 min's or so.. Love it is all I can say.
