So, how have these cars been doing lately?
Our reliability stats for the Mazda3 now include owner experiences through March 31, 2015. (Others are nearly a year behind.)
In terms of repair trips per 100 cars per year ("low" is best):
2013 Mazda3: 10, low
2013 MazdaSpeed3: 35, moderate, very small sample size
2012 Mazda3: 9, low
2012 MazdaSpeed3: 38, moderate, small sample size
2010 Mazda3: 17, low
2010 MazdaSpeed3: 7, low, small sample size
2009 Mazda3: 27, low
2009 MazdaSpeed3: 37, low, small sample size
2008 Mazda3: 51, low
2008 MazdaSpeed3: 67, moderate, very small sample size
2007 Mazda3: 64, moderate
2007 MazdaSpeed3: 38, low, small sample size
No stat for a model year? Then we very much need more participants for it. Same for those with small sample size notes. Next updates in August and November.
