With an overall 2011 Auto Reliability Grade Point Average of 3.63 over a 10-year data history, the Accord contributed to Honda Motor Company's high age-range and overall Grade Point Averages. See the table, bar graph, and list of the Top 5 Car Makers below.

The Complete Table

This page provides detailed 2011 car manufacturer reliability ratings and auto manufacturer reliability rankings in a table. It expresses the car manufacturer reliability ratings and car manufacturer reliability rankings, and makes available manufacturer reliability comparisons and reliability contrasts, using the Car Reliability Grade Point Average, or Car Reliability GPA. This car reliability index is valuable as it is an easy-to-understand, but detailed, car 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 Car Reliability Grades as a reliability index. This measure of car reliability differences, although less detailed, is valuable as it is familiar to all persons having attended primary school. The updated Car Reliability GPA is an automobile reliability statistic that is obtained from Consumer Reports' car 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 Average GPA for each car manufacturer is the average of the Average GPAsof its models. The Average Minimum GPA for each car manufacturer is the average of the Minimum GPAs of its models. The Reliable Two, Toyota Motor Corporation and Honda Motor Company, appear first in the table, because of their rather singular stature; the remaining manufacturers are listed alphabetically. Letter grades corresponding to Average GPAs and Average Minimum GPAs are determined thusly: A if the GPA is 3.50 to 4.00, B if the GPA is 2.50 to 3.49, C if the GPA is 1.50 to 2.49, D if the GPA is 0.50 to 1.49, and F if the GPA < 0.50.

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/her, if such there be.

The following bar graph depicts how much above average or below average is the 2011 Car Reliability GPA of each of the major car manufacturers selling in North America.

Bar Graph of 2011 Car Manufacturer Reliability GPAs by James Benjamin Bleeker.

There are several important points to be noted from the above bar graph. The first is that the 2011 Car Reliability GPAs of Toyota Motor Corporation and Honda Motor Company continue to be much higher than the 2011 Car Reliability GPA of any other manufacturer, a divide that has persisted for more than a quarter of a century. The second is that Hyundai Motor Company (with a 2011 Car Reliability GPA of 2.38) has very successfully distinguished itself from all of the Detroit 3 - Chrysler LLC (2011 GPA: 1.15, a D by letter grade), General Motors Corporation (2011 GPA: 1.35, a D by letter grade), and Ford Motor Company (2011 GPA: 2.14, a C by letter grade). The third is that the 2011 Car Reliability GPA of the Ford Motor Company is much higher than those of its Detroit brethren - General Motors Corporation and Chrysler LLC.

The 2011 Top 5 Car Manufacturers

Next, we list the 5 most reliable car manufacturers. The 2011 Top Five car manufacturers are:

Honda Motor Company, with an overall 2011 Car Reliability GPA of 3.47,
Toyota Motor Corporation, with an overall 2011 Car Reliability GPA of 3.44,
Fuji Heavy Industries Ltd. (Subaru), with an overall 2011 Car Reliability GPA of 2.63,
Mitsubishi Motors Corporation, with an overall 2011 Car Reliability GPA of 2.61,
Nissan Motor Company, with an overall 2011 Car Reliability GPA of 2.26
.

The 2011 GPAs of the Top 4 have changed little from 2010; Nissan Motor Company's have dropped.

The 2011 Bottom 5 Car Manufacturers

Next, we list the 5 least reliable car manufacturers. The 2011 Bottom Five car manufacturers are:

Chrysler LLC, with an overall 2011 Car Reliability GPA of 1.15,
Volkswagen AG, with an overall 2011 Car Reliability GPA of 01.23,
BMW AG, with an overall 2011 Car Reliability GPA of 1.30,
General Motors Corporation, with an overall 2011 Car Reliability GPA of 1.35,
Daimler AG, with an overall 2011 Car Reliability GPA of 1.36.

Note that both of Ford Motor Company's Detroit brethren, General Motors Corporation and Chrysler LLC, remain in the Bottom 5.

Disclosure: Site manager is currently a very small shareholder of Ford Motor Company (2011-08-27). I am not, and have not been, a shareholder of any other car manufacturer.

The method of computation of the GPAs is probably familiar to nearly every college, technical school, and high school student. 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.

AutoOnInfo.net’s Car Quality Series Volume 2: Brand Quality for Model Years 1985 to 2006 and Effect on Brand Market Shares from 1985 to 2009

AutoOnInfo.net's Car Quality Series, Volume 2: Brand Quality for Model Years 1985 to 2006 and Effect on Brand Market Shares from 1985 to 2009

This volume of AutoOnInfo.net’s car guide series offers consumers and researchers an historical summary of the reliability and durability of car and truck brands and examines how these brands have fared in their U.S. market shares. It uses 6-year-old model entries in Consumer Reports’ Used Car to Avoid – also termed Vehicles to Avoid and Worst Cars, Year by Year – and CR’s reliability charts to ascribe quality grades to automobile brands for model-year groups 1985 to 1989, 1990 to 1994, 1995 to 1999, 2000 to 2004, 2005 to 2006, and 1985 to 2006. In addition to ascribing quality grades to each brand, it provides a chart that plots the number of the brand’s 6-year-old model entries in CR’s vehicles to avoid. To examine the effect that a brand’s reliability and durability has had on sales, two or more charts depicting the brand’s U.S. market shares for calendar years 1985 to 2009 are given. These grades and charts and the author’s comments impart an historical perspective that sheds light on the present condition of surviving vehicle lines and their future prospects, individual and institutional shortcomings, and what effect these may have on the U.S.

Volume 6 of AutoOnInfo.net’s Car Quality Series is intended primarily as an aid to consumers in selecting a vehicle that both is reliable in the short term and provides a prospect of only modest repairs in the long term, and secondarily as an aid to auto industry analysts and reporters. To this end, it provides a list of the 50 Best Cars available in the U.S. in 2014 using the Overall Reliability GPA, AutoOnInfo.net’s standard measure of reliability now for several years, covering model years 2002 to 2013 for ranking pickup trucks, sport-utility vehicles (SUVs), family cars, wagons, small cars, hatchbacks, sport/sporty cars, coupes, convertibles, upscale cars, luxury cars, and hybrids, and includes each car’s reliability GPA and grade and the number of model years upon which the GPA and grade are based. As a further aid, it includes 2014 brand and manufacturer GPAs for comparison and contrast and for better assessing long term performance and ownership expenses. In addition, it offers more than 30 full color charts depicting each brand’s and car company’s share of the 10, 20, 30, 40, and 50 Best Cars and each brand’s and auto maker’s share of the best pickups, best midsize sport-utility vehicles, best small SUVs, best family cars, best wagons, best small cars, best hatchbacks, best sport/sporty cars, best coupes, best convertibles, best upscale cars, best luxury cars, and best hybrids in America. For further study and better understanding of auto quality in North America, it offers 10 charts that display, using a bar graph with an axis value of 2.00 (for quick viewing of how much above or below average a brand’s or auto maker’s  Reliability GPA falls), the 2014, 2013, 2012, 2011, and 2010 Reliability Grade Point Averages of each major brand and manufacturer, as well as a line graph plotting the 2010 to 2014 Reliability GPA ranks of the 6 most prominent manufacturers by U.S. sales.
