TrueDelta reports absolute repair rates that make the differences between cars much clearer. Results are updated four times a year, to track cars closely as they age.

We currently provide results for many Nissan models, but the 1999-2002 Quest isn't included in the survey yet. For a model year to be included, at least 25 owners have to sign up to participate.

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, participants receive full access to all results, not just those for the Nissan Quest, free of charge.
