We've updated our reliability stats for the Xterra to include owner experiences through June 30, 2013. (Another source is about 14 months behind.)

Repair frequencies, in terms of repair trips per 100 cars per year:

2010 Xterra: 27, low, very small sample size
2008 Xterra: 53, moderate, very small sample size
2007 Xterra: 32, low, very small sample size
2006 Xterra: 96, high, very small sample size
2005 Xterra: 81, moderate, small sample size
2002 Xterra: 47, low, very small sample size
2000 Xterra: 108, moderate, very small sample size

We'll have further updates in November and February.
