2012's Best-to-Worst Car and Truck Brands in North
America:
Table and Chart
by James Bleeker
This page provides the table giving the Auto Reliability GPAs of the
motor vehicle brands in 2012 and a chart
depicting the Overall Reliability GPAs of these brands in 2012.
The Table
The table below provides the 2012 Auto Reliability GPAs and Grades of car
and light truck brands 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. As well, an Overall Reliability GPA - an
average of the 4 Reliability GPAs - is provided; this may be of greatest
value to those interested in purchasing a new car and owning it for decade,
or several.
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 table is in descending order of Overall GPA, i.e.,
from best to worst.

Chart of the Reliability GPAs of North America's
Car and Truck Brands
The following bar graph depicts the Overall Reliability GPAs of North
America's car and light truck brands in 2012.

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 brand GPAs given in the table and chart above are the averages of the model
GPAs.
