TrueDelta has released updated Car Reliability Survey results for the Mazda3. All model years are covered, including the 2008.5/2009.

Most model years remain better than the average. However, repair rates have been creeping up for the older model years, and the 2004 and 2006 are now on the borderline between "average" and "better than average."

The 2008.5/2009 was "worse than average" three months ago, but has improved to "average." A single common problem with the revised audio system has been the source of the unexpectedly high repair rate. As long as no other common problems pop up, the repair rate for this year will continue to improve.

TrueDelta will have further updates in May, August, and November, so additional participants would certainly be helpful.

TrueDelta now has a separate results page for each model. The one of the Mazda3:

5/2009 - Updated Car Reliability Survey results for the Mazda3

We have updated results for the Mazda3 to include owner experiences through March 2009. In terms of successful repair trips per 100 cars per year:

2008.5-2009: 68, about average, common problem with the audio system

2008: 47, about average, might have some 2008.5s with the troublesome audio system in this sample

2007: 33, better than average

2006: 43, better than average

2005: 48, better than average

2004: 79, about average, and worse than earlier--less reliable once the warranty ends?

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.

Wasn't able to make any sense of the link but I'll look at it again when I'm not so tired.

I can totally identify with the audio problems; I have a 2007 and the 6-disc changer is broken (CDs are stuck inside the head unit). Also both FM and AM reception is horrible. I've only used one other head unit where the reception was just as bad. Went to the dealership to verify it wasn't just my car.

Have never been impressed by Sanyo electronics (their rechargable NiCd batteries are OK) in the first place; Mazda should've known better than to use that manufacturer.

We have updated results for the Mazda3 to include owner experiences through June 2009. Results are now posted separately for the MazdaSpeed3. In terms of successful repair trips per 100 cars per year:

2008.5-

2009 Mazda3: 72, about average, common problem with the audio system

2008.5-

2009 MS3: 65, see note above

2008 Mazda3: 54, about average, might have some 2008.5s with the troublesome audio system in this sample

2008 MS3: 56, again see note above

2007 Mazda 3: 29, better than average

2007 MS3: 73, about average

Sample sizes range from small to nearly adequate for the MS3, so these results are not as precise as those for the regular Mazda3. That said, only with the 2007 does the MS3 appear to require more repairs.

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.

We have updated results for the Mazda3 and MazdaSpeed3 to include owner experiences through March 31, 2010. In terms of repair trips per 100 cars per year:

2010 Mazda3: 15, better than average

2010 MS3: 40, about average, very small sample size

2008.5-
2009 Mazda3: 39, about average, common problem with the audio system

2008.5-
2009 MS3: 53, about average, small sample size, see note above

2008 Mazda3: 49, about average, might have some 2008.5s with the troublesome audio system in this sample

2008 MS3: 55, about average, again see note above

2007 Mazda3: 21, better than average

2007 MS3: 73, about average--only in its first model year is the MS3 significantly more troublesome than the regular Mazda3

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

We have updated results for the Mazda3 and MazdaSpeed3 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:

2010 Mazda3: 23, better than average

2010 MS3: 25, better than average, small sample size

2008.5-
2009 Mazda3: 34, better than average

2008.5-
2009 MS3: 51, about average, small sample size

2008 Mazda3: 40, better than average

2008 MS3: 65, about average

2007 Mazda3: 17, better than average

2007 MS3: 63, about average

2006: 46, better than average

2005: 28, better than average

2004: 69, about average

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.

The percentage with no repairs is about 85 for the 2005, 69 for the 2006, 87 for the 2007, 77 for the 2008, 72 for the 2009, and 73 for the 2010, while the percentage of lemons is about 6 for the 2008.5-2009 and less than one for the other years.

In about a week we'll start previewing the next set of results to participants. The preview results will be updated as responses come in.

As always, the more owners participate, the better the information we can provide to everyone.

We have updated results for the Mazda3 and MazdaSpeed3 to include owner experiences through September 30, 2010. Other sources of car reliability information won't cover the months since April until the summer or even fall of next year.

We don't have these stats for the MS3 yet because they require a larger sample size.

Awesome info, good to know that although other companies like Hyundai are offering really nice long warranties... that may be a negative aspect vs making a car that lasts to begin with!
