This
page has been updated to include the data that became available in 2005.
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 are
based on the performance of approximately 6 to 8 year old vehicles; those for
1998, on the performance of approximately 5 to 7 year old vehicles; those
for 1999, on the performance of approximately 4 to 6 year old vehicles;
those for 2000, on the performance of approximately 3 to 5 year old
vehicles; those for 2001, on the performance of approximately 2 to 4 year
old vehicles; those for 2002, on the performance of approximately 2 to 3
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 Reliability Percentrank Averages 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 (Toyota-Honda) vehicle. This is why Reliable Two Reliability Percentrank
Averages are used to
benchmark the top.
Extrapolations: The extrapolations of Cadillac Reliability
Percentrank averages, Cadillac DeVille Reliability Percentranks, and Cadillac
Seville Reliability Percentranks are provided to give the visitor an idea as to the relative reliability of
the Cadillac line and the Cadillac DeVille and Seville models for model years
2003, 2004, 2005, 2006, 2007, 2008, and 2009. The extrapolations are linear
regressions of degree one and are based on vehicular ages that range from 2-3
years to 6-8 years, as noted
above. If the visitor plans to purchase a new Cadillac vehicle and own it
for less than 3 years, the projections may have less applicability. Note
that of late questions regarding the viability of GM and its lines have arisen;
should GM disappear from the automotive world, the extrapolations are, of
course, without meaning.
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
Cadillac 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.
3.
Some
models appearing in the Reliability Percentranks table for the Cadillac Line may
not have a separate chart above.

4.
Cadillac
is a division of General Motors Corporation.
For those disposed to trawl trenches or troll at depths, the
following chart of Big Three Reliability Percentrank averages and extrapolations is provided.
For reference, the Reliability Percentrank averages, and an extrapolation
thereof, for Toyota Motor Corporation are included.
The extrapolations are linear regressions of degree one.
The above chart shows (1) a quite steady decline in the Reliability Percentrank
average of Chrysler through 1994, followed by a rather steady, but modest recovery, (2)
a quite steady decline in the Reliability Percentrank average of General Motors
Corporation through 1997, followed by a very modest recovery, and (3) a very
steady rise in the Reliability Percentrank average of Ford Motor Company from
1990 through
1997, followed by a rather steady decline toward the averages of Chrysler and
GM. The more recent decline by Ford suggests that its lofty extrapolation is
highly questionable. (See the
Bottom Line on Auto Reliability.)
Likely a better
guide to the reliability of a typical product for any of the Big Three comes
from an extrapolation of the Reliability Percentrank averages for the Big Three
as a group. The following chart provides this. Again, the extrapolation of the
Reliability Percentrank averages for Toyota Motor Corporation provides
reference.
Disclaimer:
Site manager views the purchase of any Big-Three-engineered vehicle as ill-advised.
