TrueDelta has released updated Car Reliability Survey results for the Mazda6.

The 2003 Mazda6 has a repair rate near the average, maybe a bit better. The sample size for this year is very small, so this result is less precise than the others.

The 2004, 2005, and 2006 Mazda6 all have "better than average" repair rates. In all three cases sample sizes are just over the minimum.

We don't have enough participants yet for the 2007, 2008, or 2009.

A big thanks to everyone who has been helping. We'll have further updates in May, August, and November, so additional participants would certainly be helpful. Especially for the 2007, 2008, and new 2009.

TrueDelta now has a separate results page for each model. The one of the Mazda6:

There's also a page with the descriptions of all reported repairs.

We have updated results for the Mazda6 to include owner experiences through March 2009. In terms of successful repair trips per 100 cars per year:

2009: 26, better than average, but very small sample size

2007: 81, about average, very small sample size, results for other years suggest that this one is not accurate.

2006: 16, better than average

2005: 24, better than average

2004: 40, better than average

2003: 91, about average, very small sample size

A big thanks to everyone who has been helping. We'll have further updates in August and November. With more participants, we could provide more precise information and cover all model years.

Not enough participants, probably because many people decided to wait for the 2009. It's often harder to get enough participants for the final model year of a design.

We have updated results for the Mazda6 to include owner experiences through June 2009. In terms of successful repair trips per 100 cars per year:

2009: 48, about average

2007: 86, about average but not far from "worse than average," but very small sample size--need more participants

2006: 29, better than average--over double the sample size as the 2007, more accurate result

2005: 42, better than average

2004: 65, about average, but close to "better than average"

2003: 53, better than average, but small sample size

A big thanks, 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.

We have updated results for the Mazda6 to include owner experiences through September 30, 2009. In terms of successful repair trips per 100 cars per year:

2009: 68, still about average, but heading in the wrong direction

2007: 86, about average, sample size--need more participants

2006: 28, better than average--larger sample size than the 2007, more accurate result

2005: 40, better than average, but not quite enough responses for a full result this time

2004: 83, about average

2003: 35, better than average, but small sample size

This is among our least consistent sets of results, probably due to the sample sizes. If more owners could participate, we could provide more precise results and cover all model years.

We have updated results for the Mazda6 to include owner experiences through December 31, 2009. In terms of repair trips per 100 cars per year:

2009: 73, still about average, but heading in the wrong direction

2007: 89, about average

2005: 34, better than average, but not quite enough responses for a full result this time

A big thank you, once again, to everyone who has been helping. That said, this is again among our least consistent sets of results, probably due to the sample sizes. If more owners could participate, we could provide more precise results and cover all model years.

We have updated results for the Mazda6 to include owner experiences through June 30, 2010. Other sources of car reliability information won't cover the more recent months until the summer or even fall of next year.

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

2009: 57, about average

2007: 50, about average, small sample size

2007 MS6: 95, worse than average, very small sample size

2006: 31, better than average

2006 MS6: 49, better than average, very small sample size

2005: 6, better than average

2004: 82, about average

2003: 60, better than average, but small sample size

Thank you, once again, to Antoine, this forum, and everyone who has been helping. That said, this is again among our least consistent sets of results, probably due to the sample sizes. If more owners could participate, we could provide more precise results and cover all model years.

2006: 33, better than average

2004: 73, about average

2003: 79, about average, but 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.

For the 2009, the percentage with no repairs is about 67, and the percentage of lemons is less than one. These stats require more data, so we don't yet have them for other model years.
