If it's Jeep keep it jeep, slightly more expensive, but whatever problem it is will be fixed... Quite often all that needs to be done is cleaning the filters (just like your house ones), and they will tell you if that is all that needs to be done... where as some of the off street guys sometimes hold theirf breath, let out a big sigh, and tell you that half of it needs replaced... in hinglish of course.

Not sure where the Chrysler service centre is, but i'm sure the marhaba has it.
