¹Current data are insufficient to warrant charts.

This page has been updated to include the data that became available in 2003.

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 1995 are based on the performance of approximately 6 to 8 year old vehicles; those for 1996, on the performance of approximately 5 to 7 year old vehicles;  those for 1997, on the performance of approximately 4 to 6 year old vehicles;  those for 1998, on the performance of approximately 3 to 5 year old vehicles;  those for 1999, 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 Chevrolet. This is why Chevrolet Reliability Percentrank medians 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 Honda. This is why Honda line Reliability Percentrank medians 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 Plymouth 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 Plymouth Line may not have a separate chart above. To view the table giving the Reliability Percentranks for the Plymouth line, click here.

4.   Plymouth is a defunct division of the Chrysler Group of DaimlerChrysler AG.

For those disposed to trawl trenches or troll at depths, the following chart is provided:

The extrapolations of the Reliability Percentrank averages for Ford, Chrysler, and General Motors are linear regressions of degree one. 

The above chart shows a very steady decline in the Reliability Percentrank average of General Motors and a rather stable Reliability Percentank average for Chrysler. Ford's Reliability Percentrank average rose from 1990 to 1997 and then began a decline; however, the improvement in this seven-year period was dramatic enough to give the regression line of Ford's Reliability Percentrank averages for the entire data history a rather large positive slope and to ensure that generally a consumer may purchase a Ford product with a measure of confidence that it will have a greater Reliability Percentrank than a General Motors product. Nonetheless, comparisons of the available data and their extrapolations, when present, for models of interest are recommended. Disclaimer: Site manager views the purchase of any Big Three-engineered vehicle as ill-advised.

1 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.
