We've updated our reliability stats for the Boxster and Cayman to include owner experiences through June 30, 2016. Reliability information elsewhere is based on a survey conducted in April 2015--well over a year ago.
Repair frequencies, in terms of repair trips per 100 cars per year (lower is better):
2016 Boxster and Cayman: 30, moderate, small sample size
2015 Boxster and Cayman: 24, moderate, small sample size
2014 Boxster and Cayman: 27, moderate
2013 Boxster: 26, low
2009 Boxster and Cayman: 15, low, small sample size
2008 Boxster and Cayman: 49, low
2007 Boxster and Cayman: 37, low
2006 Boxster and Cayman: 31, low
2005 Boxster: 44, low
2004 Boxster: 32, low, small sample size
2003 Boxster: 58, low
2002 Boxster: 28, low, small sample size
2001 Boxster: 54, low
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:
2014 Boxster and Cayman: 76, < 1
2013 Boxster: 82, < 1
2008 Boxster and Cayman: 54, < 1
2007 Boxster and Cayman: 69, < 1
2006 Boxster and Cayman: 74, < 1
2005 Boxster: 61, < 1
2001 Boxster: 65, 3
We'll have further updates in November and next February. The more owners participate, the more comprehensive and precise these will be.
