We have updated our reliability stats for the xB (on our redesigned site) to include owner experiences through December 31, 2011.
Repair frequencies, in terms of repair trips per 100 cars per year:
2010: no repairs reported yet, only 10 responses
2009: no repairs reported in the past year, 22 cars
2008: 17, better than average
2006-2006.5: 5, better than average
2005: 58, about average, small sample size
2004: 61, about average, very small sample size
We'll have further updates in May and August. With more participants, we could provide more precise information and cover all model years.
