The X-Pan is a well built camera. It's very solid.
The X-Pan was made by Fuji and was sold in Japan as the TX-1. I'm not sure about service, but I would assume that it would begin with Hasselblad. I don't know if it means that Hasselblad USA would do the work or if the camera would be sent to Japan.
The build quality of the X-Pan is excellent. That said, because it's a rangefinder, there is always the possibility that the rangefinder system could be knocked out of calibration.
The camera is battery dependent. It can't do anything if the batteries die. Well, it can focus, because that is manual, but that's about it.
You don't read many comments about X-Pan breakdowns, although certainly it has happened to some owners.
