Our reliability stats for the Altima now cover the year ending June 30, 2015. (Others are over a year behind, and so report how these cars were doing when a year younger.)
Repair trips per 100 cars:
2015 Altima: 0, low, very small sample size
2014 Altima: 36, moderate
2013 Altima: 38, moderate
2012 Altima: 14, low
2011 Altima: 29, low, small sample size
2010 Altima: 22, low
2009 Altima: 67, moderate
2008 Altima: 19, low
2007 Altima: 33, low
2006 Altima: 80, moderate, very small sample size
2005 Altima: 59, low
2003 Altima: 59, low, small sample size
We have two additional statistics, "Nada-odds" and "Lemon-odds", to indicate the percentage of cars with no repairs in the past year and those that required 3+ trips to the repair shop:
2013 Altima: 70, < 1
2010 Altima: 82, < 1
2008 Altima: 87, < 1
2007 Altima: 79, < 1
If a model year isn't listed, or its sample size is small, then we especially need more owners involved.
