Mazda5 reliability - how does it compare?

Just enhanced the related repair history survey so that it can (optionally) be used as a personal car maintenance record.

As always, more participants would be helpful. Updated Car Reliability Survey results in May, with a preview for participants next month.

Car reliability research
 
We have updated results for the Mazda5 to include owner experiences through March 31, 2010. In terms of repair trips per 100 cars per year:

2009: 10, better than average, small sample size

2008: 23, better than average, small sample size

2007: 35, better than average

2006: 79, about average, common problems with the front suspension, some rust where roads are salted

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 2006, the percentage with no repairs is about 49, and the percentage of lemons is about 3. These stats require more data, so we don't yet have them for other model years.

A big thank you, once again, to Antoine, this forum, and 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.

Mazda Mazda5 reliability comparisons
 
We have updated results for the Mazda5 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: no repairs reported yet, 18 participants

2009: 7, better than average

2008: 45, about average, small sample size

2007: 38, better than average

2006: 79, about average, common problems with the front suspension, some rust where roads are salted

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 2006, the percentage with no repairs is about 53, and the percentage of lemons is about 7. These stats require more data, so we don't yet have them for other model years.

Starting this month we have a new question to measure, as objectively as possible, the severity of a problem. Many people have been asking for reliability stats that weight problems by how severe they are, and once we have enough responses with the revised survey we'll start providing this.

Also, updated reliability stats this month.

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

We have updated results for the Mazda5 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.

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

2010: no repairs reported yet, 22 participants

2009: 24, better than average

2008: 38, better than average, small sample size

2007: 36, better than average

2006: 75, about average, common problems with the front suspension, some rust where roads are salted

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 2006, the percentage with no repairs is about 59, and the percentage of lemons is about 3. These stats require more data, so we don't yet have them for other model years.

I think I am misreading something. So the stat will change in the negative direction as you add more owners who do not report an issue than owners who do?

I think you are correct but maybe I don't understand, either. I have a 2008 Mazda 5 in South Texas and I have had a window switch and a thermostat go bad in two years at 36,000 miles; both were under warranty. I just don't see the shock/sway-bar issue mentioned. The 2008 Mazda 5 went from above average to below average in just a few months. Isn't the suspension the same on all the Mazda 5s? Why would the 2008 be worse than others? It must be the sample makeup.

There were TSBs and changes to the suspension over the years. They were minor changes that apparently did little to silence the complaints.
 
One thing that might not be clear is that the stats are always based on the previous year. When a repair occurred more than a year before the stated end date, it's no longer included in the analysis.

There were some suspension repairs reported by owners of the 2007s, but these generally occurred over a year ago.

This said, owners of the 2008s are now reporting more suspension problems than owners of the 2007s ever did.

So it looks like Mazda's suspension "fixes" with the 2008 refresh actually caused more problems than they solved.

Not many suspension repairs reported for the 2009s yet. Two possibilities:

1. Mazda fixed them with further revisions

2. The 2009s don't have enough miles on them yet, and owners will start reporting problems soon
 
We have updated our car reliability stats for the Mazda5 (on our redesigned site) to include owner experiences through September 30, 2011.

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

2010: 28, better than average

2009: 49, about average

2008: 130, worse than average, very common problems with rear shocks and swaybar bushings

2007: 29, better than average

2006: 59, better than average, common problems with the front suspension, some rust where roads are salted

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.

2010: 75, < 1

2006: 54, 3

You spend a lot less and likely get better quality parts :)

WRT to the survey, this is not a problem. One question on the form asks who performed the repairs, and DIY is an option. The main difference is that you then report hours instead of days.
