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're already reporting a result for the 2008, but haven't enough owners signed up for earlier years.
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.
