The Updated 2010 Auto Reliability Grade Point Averages (GPAs) and Grades for Motor Vehicles Sold in North America: The Complete Table and the Top 10 Autos, the Top 20 Autos, the Top 30 Autos, the Bottom 10 Autos, the Bottom 20 Autos, and the Bottom 30 Autos

The V6 Toyota 4Runner has a 2010 Auto Reliability GPA of a perfect 4.00 over a 10-year data history and is the only vehicle to have such a distinguished reliability record in 2010. It is the best of the best. See the table and list of the Top 10 below.

The Complete Table

This page provides updated 2010 auto reliability ratings and auto reliability rankings in a reorderable 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: 2010, (2) Consumer Reports: Used Car Buying Guide: 2010, and (3) the April 2010 issue of the Consumer Reports magazine. Column reordering on this page is Ajax enabled to make for a convenient and easy-to-use reordering option.

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.

To arrange any column of the reliability table in ascending order (smallest value on top), click the header of the column. Arranging a reliability GPA or Grade column in ascending order will place the lowest reliability values and least reliable autos at the top (after those with empty cells) and the highest reliability values and most reliable autos at the bottom of the table. This automobile ranking will permit the visitor to better visualize automobile differences. The reliability ranking feature is Ajax enabled for ease of use.

To rearrange any column of the reliability table in descending order (largest value on top), click the header one more time. Arranging a reliability GPA or Grade column in descending order will place the highest reliability values and most reliable autos at the top.

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.

General Motors Corporation and the Chrysler Group dominate this 2010 worst auto list. GM accounts for 15 of 2010's least reliable automobiles, the Chrysler Group - another 7 of the least reliable automobiles, Volkswagen AG - 4 of the least reliable automobiles, and Daimler AG, Kia Motors Corporation, Ford Motor Company, and Land Rover each account for 1 of the least reliable automobiles. Each manufacturer's percent share of the 2010 least reliable automobiles is depicted in the following bar graph.

Auto Manufacturer Percent Shares of the 30 Least Reliable Automobiles of 2010

Notice that Toyota and Honda products dominate the upper end of the reliability spectrum (accounting for a combined total of 90% of the best automobiles) more than GM and the Chrysler Group dominate the bottom end of the reliability spectrum, which two of the Detroit Three account for only 73.3% of the worst automobiles. In other words, the best automobiles are concentrated in two automobile manufacturers, but the worst automobiles are more broadly distributed among motor vehicle manufacturers.

Also note that Toyota Motor Corporation, Honda Motor Company, all other auto manufacturers headquartered in Japan, and Hyundai Motor Company (headquartered in South Korea) have not one entry among the 30 worst automobiles. Kia Motors Corporation (South Korea) has one entry. However, two North America-based auto manufacturers and one Europe-based auto manufacturer have multiple entries.

Caution      When the number of model years of data (appearing in the far right column) for a vehicle is limited to more recent years, the reliability GPAs, Average GPA, and Minimum GPA of that vehicle may be less reflective of the vehicle's reliability over a longer period of time. For example, the Ford Fusion has only a 4-year reliability history, so if one is considering purchasing a used Fusion, or a new Fusion but owning it for 6 or more years, it may be better to examine the GPAs of the Ford line in the outer years.

A PDF version of the above table of 2010 updated automobile reliability GPAs and grades is available for downloading and/or printing for convenient anytime, anywhere accessibility. As the quality standing of each auto manufacturer changes slowly over time, you may wish to save the PDF version for your perusal over the next several decades, for sharing with friends or following generations, or for negotiating with recalcitrant dealerships. A PDF version of the above list of the 30 most reliable automobiles and a PDF version of the above list of the 30 least reliable automobiles are also available. In addition, a PDF version for the 2009 Reliability GPAs is available, which may be particularly useful if a vehicle of interest does not appear in the 2010 list.

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.

The table is an immediate import from Microsoft's Access and a more distant import from Microsoft's Excel. The integration of the Access database into Microsoft's Web Expression software makes the reordering of the columns a rather simple task. For Ajax's partial post back, the ScriptManager and UpdatePanel controls were inserted by dragging; <ContentTemplate> was manually inserted into the code immediately after the ScriptManager and Update controls.
