My parents have a 9-3X, same haldex AWD system as your NG9-5. They had a 'service XWD' message on their dash, and maybe, mayyybe a little hesitation from a stop/around a corner. Turned out to be a bad diff fluid pump and rear diff fluid that, according to the service writer, was 'like sludge.' The diff does seem to be the only real 'common' replacement on the systems so far.
