Got the car back today after a few days in the shop. Hope the noise is gone, too early to tell. Not sure if it's a placebo effect, but I think it idles more smoother now. Dash is in tact and appear to be visibly well put together. Cup holder led lamp and transmission illum did not work, but I checked it out and the illum wire were looping back to itself rather than to the led lamps itself. I had the compressor, evaporator and the active head rest replaced under warranty, with a brand new dodge journey as a loaner included. So far extremely happy with the service the guys at Maddington Jeep Service center handled my case and the patience they had to put up with. Most importantly what helped the most was also a printed out of this forums..
So far no rattles.. Not that I could tell on the long drive home anyway. It is a well built car and from what I've noticed with past Chrysler cars, everything fitter is precised and tightly fitted, even down to foam behind kickboards etc... So it is well built. Jeep is like that when I took apart the center console tonight to look at the cup holder lighting. However, your service dealer does not equate to the same guy who worked on my car. Good luck.
