The Complete Table

This page provides updated 2011 auto reliability ratings and auto reliability rankings in a table listing most of the convertibles, coupes, sedans, hatchbacks, wagons, minivans, sport-utility vehicles (SUVs and XUVs), and pickup trucks sold in the U.S. It expresses the auto reliability ratings and auto reliability rankings, and makes available auto reliability comparisons and auto reliability contrasts, using the Auto Reliability Grade Point Average, or Auto Reliability GPA. This auto reliability index is valuable as it is an easy-to-understand, but detailed, auto reliability measure, and is familiar to many having attended secondary school and nearly all who have received some post-secondary education. The page also employs Auto Reliability Grades as a reliability index. This measure of auto reliability differences, although less detailed, is valuable as it is familiar to all persons having attended primary school. The updated Auto Reliability GPA is an automobile reliability statistic that is obtained from Consumer Reports' auto reliability survey data summarized in the reliability tables of (1) Consumer Reports: New Car Buying Guide: 2011, (2) Consumer Reports: Used Car Buying Guide: 2011, and (3) the April 2011 issue of the Consumer Reports magazine.

The Reliable Two, Toyota Motor Corporation and Honda Motor Company, appear first in the table, because of their rather singular stature; the remaining automobile manufacturers are listed alphabetically.

Letter grades for automobile reliability are determined thusly: A if the Auto Reliability GPA is 3.50 to 4.00, B if the Auto Reliability GPA is 2.50 to 3.49, C if the Auto Reliability GPA is 1.50 to 2.49, D if the Auto Reliability GPA is 0.50 to 1.49, and F if the Auto Reliability GPA < 0.50.

Reliability GPAs for 4 age ranges are given so that the visitor may examine more thoroughly the age range that is of greater interest to him or her, if such there be.

Lists below the table give (1) the 10, 20, and 30 most reliable autos with at least a 3-year reliability data history and (2) the 10, 20, and 30 least reliable autos with at least a 3-year reliability data history.

Ranking by reliability - the infrequency of reported serious problems - continues to place Toyota Motor Corporation and Honda Motor Company on top. Toyota accounts for 20 of 2011's 33 most reliable automobiles and Honda - another 11 of the most reliable automobiles, for a combined total of 31. Nissan Motor Company and Mazda Motor Corporation each have one of the most reliable automobiles. Each manufacturer's percent share of the 2011 most reliable automobiles is depicted in the following bar graph.

All of the 33 most reliable automobiles of 2011 were product offerings by corporations headquartered in Japan.

General Motors Corporation and the Chrysler Group dominate the 2011 worst auto list - long the norm. GM accounts for 12 of 2011's least reliable automobiles, the Chrysler Group - another 7 of the least reliable automobiles, Volkswagen AG - 4 of the least reliable automobiles, Ford Motor Company - 2 of the least reliable, and Daimler AG, Mazda Motor Corporation, Kia Motors Corporation, BMW AG, and Nissan Motor Company each account for 1 of the least reliable automobiles. Each manufacturer's percent share of the 2011 least reliable automobiles is depicted in the following bar graph.

Note that Toyota and Honda products dominate the upper end of the reliability spectrum (accounting for a combined total of 93.9% of the best automobiles) far more than GM and the Chrysler Group dominate the bottom end of the reliability spectrum, which two of the Detroit Three account for only 63.3% of the worst automobiles.

In summary, the best automobiles are concentrated in two automobile manufacturers, but the worst automobiles are more broadly distributed among motor vehicle manufacturers.

The method of computation of the GPAs is probably familiar to nearly every college, technical school, and high school student (at least I hope so). A Grade Point of 4.00 (that is, an A) is given to a Consumer Reports "Much Better Than Average" rating, a GP of 3.00 (that is, a B) is given to a CR "Better Than Average" rating, a GP of 2.00 (that is, a C) to an "Average" rating, a GP of 1.00 (that is, a D) to a "Worse Than Average" rating, and a GP of 0.00 (that is, an F) to a "Much Worse Than Average" rating. A Grade Point Average (GPA) is an average of the Grade Points and is computed using Microsoft's Average(a:b,[c:d],...) function. The Average GPA given in the table above is the average of the four 4-year GPAs.
