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.
