2013's Reliability GPAs and Grades for Cars and Trucks Sold in North America: Summary and Menu
by James Bleeker

(If you are using the Mozilla Firefox browser, it is best to click the refresh button once, or twice, to ensure that you are viewing the entire page, as it seems that Firefox is graphics and/or data-rich challenged. If you are using Google Chrome, the drop-down menu to the left works only hesitantly. The side menus of site manager's other two auto quality websites www.CarsOnInfo.net and www.CarQualityInfo.net are more Google friendly.)

Pages in this section of AutoOnInfo.net provide tables and charts on auto reliability in 2013. All tables offer Reliability GPAs for 4 age ranges, an Overall Reliability GPA and corresponding Reliability Grade, and a Minimum GPA and corresponding Grade. All three pages have a chart that depicts some or all of the Overall GPAs given within the table, from best to worst. The first of the following pages has three charts that depict manufacturer shares of the best and worst cars and trucks in America in 2013.

The 2013 Chart of Auto Manufacturer GPAs

Below is the chart depicting each auto manufacturer's 2013 Overall Reliability GPAs

Chart of the 2013 Auto Reliability GPAs of Auto Manufacturers with Sales in the US.

Note the very sizable drop in GPA from Honda Motor Company to Mitsubishi Motors Corporation.

The Auto Reliability GPAs are automobile reliability statistics that are obtained from Consumer Reports' auto reliability survey data summarized in the reliability tables of (1) Consumer Reports: New Car Buying Guide: 2013, (2) Consumer Reports: Used Car Buying Guide: 2013, and (3) the April 2013 issue of the Consumer Reports magazine.

The method of computation of the GPAs is probably familiar to nearly every college, technical school, and high school student. For each model year, a Grade Point of 4.00 (that is, an A) is given to a Consumer Reports Used Car Verdict of "Much Better Than Average," 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 4-year Grade Point Average (GPA) is an average of the Grade Points and is computed using Microsoft's Average(a:b,[c:d],...) function. The Overall GPA of a model is the average of the four 4-year GPAs. The GPAs of brands and manufacturers are the averages of the model GPAs.

The 100 Worst Cars in America in 2013

The 100 Worst Cars in America in 2013 offers a list of the worst cars and trucks available in the U.S. It uses AutoOnInfo.net’s Overall Reliability GPA covering model years 2003 to 2012 for ranking pickup trucks, sport-utility vehicles (SUVs), minivans, family cars, wagons, small cars, hatchbacks, sport/sporty cars, coupes, convertibles, upscale cars, and luxury cars in order to aid consumers in avoiding a vehicle that may require a larger number of repairs and a greater number of expensive repairs.

AutoOnInfo.net’s Car Quality Series, Volume 3: Car Guide and Shopping Companion: The 2012 Reliability GPAs and Grades of the 6-to-10-Year-Old Cars and Trucks from Model Years 2002 to 2005

Volume 3 of AutoOnInfo.net’s Car Quality Series offers quality ratings on car and truck models, brands, and manufacturers using Auto Reliability Grade Point Averages (GPAs) and Grades. With these measures of performance, this e-guide brings to the aid of auto consumers a convenient, anywhere, anytime source of automobile information on enduring reliability. As a further aid, this book provides graphs depicting both automobile brand and manufacturer spectral signatures and density functions.

Ratings and rankings of vehicle models, brands, and manufacturers are for North American model years 2002 to 2005 when the cars and trucks were between the ages of 6 and 10 years old. Used car buyers may use the Reliability GPAs and Grades as a valuable shopping tool for earlier and later model years as well. New car buyers looking for models and lines that have withstood the test of time may use the GPAs and grades as a guide for what runs well over a multi-year time span. Motor vehicles graded and ranked include small cars, family cars, upscale cars, luxury cars, sport cars, small SUVs, midsize SUVs, large SUVs, minivans, and pickup trucks.

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.
