It is difficult to blame a dealer for being unable to repair a modification that the owner performed. The folks at the dealership just go by the shop manual, and that does not include any aftermarket modifications, whether quality or junk, that the owner had installed. The highbeams on the HID equipped Murano are not really highbeams at all - they just move a shutter to allow more light to pass through the projector (its the exact same brightness, exact same "bulb") and aim it further down the road.
