I got the same problem too... the air con sounds like it is leaking air or something... but it comes on and off... so it is really annoying... and I only have the car for about one month... I am going to bring it back to the dealer this wednesday and have it check out...
Also, I notice this tlicking noise / body noise... it is really annoying... it happens once in a while... and it is driving me insane!!! Does anyone know what is this noise?
One final noise is my belt squeek every morning... i am sure the alernator belt wasn't tension properly... so I am going to have the deal fix that also...
Hopefully, the deal will be able to get ride of all these noises as it is driving me crazy!!! ahhahahahahaha.....
