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.
We've had strong participation by Fit owners, but mostly for the 2007. More owners of the 2008 very much needed. (And more 2007s would also be helpful.)
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.
