2012's Worst Cars and Trucks Sold in North America: Table and Charts
by James Bleeker

This page provides the table giving the 2012 Auto Reliability GPAs of the worst cars and trucks in 2012, a chart of manufacturer shares of the worst in 2012, and a chart depicting the Overall Reliability GPAs of the 20 best vehicle models in 2012 (21 by tie) and 20 worst vehicle models in 2012 (22 by tie).

The Table

The table below provides the 2012 Auto Reliability GPAs and Grades of the worst of the convertibles, coupes, sedans, hatchbacks, wagons, minivans, sport-utility vehicles (SUVs and XUVs), and pickup trucks sold in the U.S.

Reliability GPAs for 4 age ranges are given so that the visitor may examine more closely the age range that is of greater interest to him or her.

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.

The list of the worst in 2012 includes those vehicles with an Overall Auto Reliability GPA from 0 to 1.84 - in letter grade, from the lowest F to a low C. The list is in ascending order of Overall GPA, i.e., from worst to less worse.

The list of the worst cars and trucks in 2012 is of value to those buyers who want to avoid the worst, but are rather indifferent to whether a vehicle model is among the best.

Note that among the worst vehicles in 2012, there is not one by Toyota Motor Corporation, Honda Motor Company, Suzuki Motor Corporation, or the Subaru Division of Fuji Heavy Industries. Also, there is not one from the Infiniti line of Nissan Motor Company.

The manufacturers which have offered one or more of the most trouble prone vehicles in 2012, as reported by Consumer Reports subscribers and measured by the Overall Reliability GPA, are General Motors Corporation (with 5 of the 13 worst, 8 of the 22 worst, 13 of the 30 worst, 16 of the 40 worst, 19 of the 50 worst, 22 of 62 worst, 27 of the 73 worst, 29 of the 82 worst, 32 of the 93 worst), the Chrysler Group (with 1 of the 13 worst, 4 of the 22 worst, 6 of the 30 worst, 7 of the 40 worst, 9 of the 50 worst, 13 of the 82 worst, and 16 of the 93 worst), Volkswagen AG (with 11 of the 93 worst), Ford Motor Company (with 9 of the 93 worst), BMW AG (with 6 of the 93 worst), Daimler AG (with 5 of the 93 worst), and various other manufacturers.

In summary, the worst automobiles are somewhat concentrated in two automobile manufacturers - General Motors Corporation and the Chrysler Group. However, the worst in 2012 are much more broadly distributed among manufacturers than are the best in 2012.

Charts of Manufacturer Shares of the Worst in 2012

First is a bar graph of the auto manufacturer shares of the 30 worst cars and trucks in 2012.

Automobile Manufacturer shares of the 30 worst cars and trucks in 2012.

All but one of the 30 worst have a letter grade of F.

Next is a bar graph of the auto manufacturer shares of the 50 worst cars and trucks in 2012.

Automobile Manufacturer shares of the 50 worst cars and trucks in 2012.

All of the 50 worst have an Overall GPA of less than 1.00.

Chart of the Reliability GPAs of the Top 21 and Bottom 22 Cars and Trucks

The following bar graph provides Overall Reliability GPAs of the 20 best cars and trucks (21 by tie) and 20 worst cars and trucks (22 by tie).

Bar graph depicting the overall Reliability GPAs of the 20 best cars and trucks (21 by tie) and 20 worst cars and trucks (22 by tie) in 2012.

 

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.

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. 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 given in the table and chart above is the average of the four 4-year GPAs.

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.
