We have updated our reliability stats for the Xterra to include owner experiences through June 30, 2011.

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

2006: 124

2005: 183

Both are wore than average. Xterras and Pathfinders of this vintage (Frontiers as well?) seem prone to cooling system failures that can lead to automatic transmission failures.

Thank you, once again, to everyone who has been helping. We'll have further updates in November and February. With more participants, we could provide more precise information and cover all model years.
