This
page has been updated to include the data that became available in 2007.
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.
Note
that Reliability Percentranks for model year 2004 are based on one year of data.
Consequently, the Reliability Percentranks for individual models of that year are more
subject to statistical fluctuation. These early data have been provided as several
visitors have expressed interest in more current Percentranks; however, a better
guide to the reliability of a new model are likely the five-year averages.
To
view charts of the Reliability Percentrank averages for the Oldsmobile line and
an extrapolation of these Percentranks to
2003 and 2004 and individual charts
of the Reliability Percentranks for six of the
models of the Oldsmobile line, click here.

Oldsmobile is a defunct division of
General Motors Corporation.

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. |
|
All shares are rounded to two
significant digits. |
|
CR 2005 Quick Picks are quick pick
models of model year 2005. |
|
Note: A rebadge of a product
engineered by Toyota, but sold by another auto manufacturer, is
omitted from the latter's share. |
