From all I've read it's a noise issue between the electronics or comm for the cluster and the energy for starting the HID. Some say that it's a cable routing issue. Don't know. The failures are typically ballast related and have been blamed on the on / off headlamp on crank. I can't really tell you anything other than I experienced the low beam ballast issue with the xenonking set I had and that I've read many users complain about those two issues.
On the Gen II the guys are turning the key on , pressing the start switch, and then pulling the clutch in to get around the on/off headlight.
