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.

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.

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).

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.

and manufacturers are better than good and worse than bad since 2001.
