2006 nissan xterra clutch problem

My brother just bought a 06 xterra with 30,000 miles and the clutch gave out complete with a burnt up flywheel. Anyone have the same problem with the xterra? Any service bulletins that you are aware of? He said that the contact point on the clutch pedal was very high, is this a design flaw or just a worn out clutch?

THanks
