The 2012 Chart of Auto Manufacturer GPAs

Below is the chart depicting each auto manufacturer's 2012 Overall Reliability GPAs

Bar graph depicting the 2012 Overall Reliability GPAs of Auto Manufacturers with Sales in North America.

Note the very sizable drop in GPA from Toyota Motor Corporation to Suzuki Motor 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: 2012, (2) Consumer Reports: Used Car Buying Guide: 2012, and (3) the April 2012 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. Helping to inform consumers which autos, brands, and manufacturers are better than good and worse than bad since 2001.

More detail on brand Quality Grades is given in the Kindle ebook entitled's Car Quality Series, Volume 2: Brand Quality for Model Years 1985 to 2006 and Brand Market Shares from 1985 to 2009. Links to the Amazon page offering the book are given below.

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