Update on my previous post: After being completely ignored by the service manager (no returned phone calls, and no response to several negative survey responses) I took our Jeep to Aamco on Valley View. Within a few hours they were able to diagnose the problem with our transfer case - Desert 215 Jeep put it together wrong when they "repaired" it!! After getting a couple parts overnight, Aamco had us back on the road - with full 4wd capabilities - the next day. Desert 215 Jeep caused and additional $303 worth of repairs because their techs are incompetent. Save yourself time and money and stay away from this place.
