Timing chain failures on Pathfinder

There was mention in Carsguide (March 1, 2014) of a 2011 Pathfinder having timing chain trouble. I've just bought a 2013 R51 2.5-litre automatic diesel, is this in line for the timing chain trouble? You talk of keeping up the service, my previous diesels have always had oil and filter changes every 5000 km, is this helpful?
