Because existing sources of auto reliability information left much to be desired, in late 2005 I started conducting my own reliability research at TrueDelta.com. TrueDelta reports absolute stats like "trips to the shop" that make the differences between cars much clearer. Results are updated four times a year, so any significant changes in a model's reliability become apparent quickly.
Thanks to the support of this forum, we've been able to provide six sets of results for the Mazda3 so far, the most recent a few days ago (see results thread in the regular Mazda3 forum).
Up to this point it hasn't been necessary to report results separately for the MazdaSpeed3, since the very small number of repairs that have been reported have not been powertrain-related. But in case such repairs creep up, it will be good to have a sufficient sample of both the regular Mazda3 and the MS3.
Participants simply report repairs the month after they occur on a one-page survey. When there are no repairs, they simply report an approximate odometer reading four times a year, at the end of each quarter.
To encourage participation, panel members receive full access to the results for free.
