This
page has been updated to include the data that became available in 2007.
Percentranks:
A
model's Reliability Percentrank is a ranking of that model's Reliability Score
relative to all other Reliability Scores for the given model year and age range.
The percentrank was computed using the Percentrank function of Microsoft's Excel
2002 and, as the first part of the compound word percentrank suggests, is
a value between 0.00 and 1.00. If a model's Reliability Percentrank is near
0.00, it has a very low Reliability Score, and if a Percentrank is near 1.00, it
has a high Reliability Score. For a more detailed explanation of Reliability
Percentranks and Reliability Scores, click
here to be taken to the Methodology page.
The Reliability Percentranks and Percentrank Averages for 1988 to
1997 and 1999 are
based on the performance of approximately 6-to-8-year-old vehicles; those for
1998, on the performance of approximately 7-to-9-year-old vehicles; those
for 2000, on the performance of approximately 5-to-7-year-old vehicles;
those for 2001, on the performance of approximately 4-to-6-year-old vehicles;
those for 2002, on the performance of approximately 3-to-5-year-old
vehicles; those for 2003, on the performance of approximately 2-to-4-year-old vehicles.
Benchmarks:
Site manager's conjecture is that if a person cares little about
what he or she drives, he or she still likely would not want to drive anything
worse, or easily noticeably worse, than a typical Big Three vehicle. This is why
Big-Three-vehicle Reliability
Percentrank means are used to benchmark the bottom. At the other end, site
manager's conjecture is that if a person has an eye for quality, he or she likely
would not want to own a vehicle that is much, if any, less than a typical
Reliable Two. This is why Reliable-Two Reliability Percentrank means are used to
benchmark the top.
Advisories:
1.
This
site gives a Reliability Percentrank of .6 or below a Reliability Grade of F,
per the high standards, and a Reliability Percentrank of .76 or below a
Reliability Grade of F, per the exacting standards.
To view the table giving the Reliability Grades - High Standards for the
Mazda line, click here.
2.
Nothing
on this web page should be viewed as suggesting that site manager considers a
model-year with a Reliability Percentrank below .9, or a model with a 5-year
or 10-year Reliability Percentrank average below .9, to be acceptable for
purchase or lease.

models appearing in the Reliability Percentranks table for the
Mazda
Line may

Mazda's one entry,
the Mazda3 i, may have been pulled from Consumer Reports'
Overall Quick Pick List due to a
"Poor"
side-impact crash test rating by the Insurance Institute for
Highway Safety. The Insurance Institute's rating did cause
Consumer Reports to pull the Mazda3 from its recommended
list. |

If the vehicle model is too new for a 1999-2003 Reliability Percentrank average to exist, the early 2004 Reliability Percentrank
is used when such exists. |
|
If several editions of a
model have different Reliability Percentrank averages,
an average of the averages is used. If a Reliability
Percentrank average for only one edition of the model is
available, that average is used. |
|
All shares are rounded to two
significant digits. |
|
CR Good Bets are models that have
several
model years between 1997 and 2006 of better-than-average reliability
and have performed well on Consumer Reports' road tests. An auto
Reliability Percentrank is
a measure of relative overall reliability used by Auto on Info. |
|
Note: Two rebadges of products
engineered by Toyota, but sold by another auto manufacturer, are
omitted from the latter's share. |
