Baffling noise issue. My 2013 XV Premium has 67,000 miles. No offroad. Have a light "hammering" noise under car when turning. My first thought was "axle"; except the noise is 'Intermittent', not effected by braking/accelerating; and strangest of all - seems to 'shift' from side to side / front to back. (!) Anybody else going BONKERS with this?
