It's really incredibly stupid. Toyota went from 1.08 last year to
1.17 this year in terms of problems PER CAR. No retail car customer
in their right mind owning one or two new Toyotas (or any other brand)
would consider a change of 0.09 problems in the first 90 days
something meaningful in terms of making a buying decision. There is
so little difference between most brands that the whole thing has

Well, the thing is, NONE of the cars today have enough initial defects to
be considered alarming... all of them are far better than anything made
a couple decades ago.
So, really, using initial defects to compare vehicles is useless because
the defect levels are all in the noise floor.
The problem is, though, that what I want to know is how reliable a car
will be after I've been driving it for twenty years, and measuring that
without first driving the car for twenty years isn't possible. So there
really isn't a good metric for what I most want to know, and the metric
that _is_ available is effectively useless. It's a sad state of affairs.

One problem with the JD Powers and Assoc. survey is that it combines all
problems. So, if there a problem with a loose screw in the dashboard or
the engine caught fire and the car is trashed, the problems are weighted
equally. Another problem with the survey is that these are owner
reported problems. So the owners of a particular brand or model of car
might be less likely to report a problem than owners of another brand or
model. Finally, this is only during the first 90 days of ownership. So
if a car's brakes completely fail, resulting in a wreck that destroys
the car is not reported at all.
What do you mean by the last sentence? If the brakes fail within the first
90 days, it's going to be reported. Why would think it wouldn't?
Problems outside of the IQS 90 days, would be covered by the JD Power
Vehicle Dependability Study which would be three years from the current
model year. (e.g. the 2010 survey covered problems with the 2007 model year
I actually filled out one of these surveys for my Nissan Frontier. They
asked a lot of questions. What they put in the press releases is just a
teaser. JD Power makes money by selling the results to companies, not by
giving away the information. Too bad they don't share more of the
information with the public - but then if they gave a way the good stuff,
how would they make money.
