The Honda Fit has an early 2011 Auto Reliability
GPA of a perfect 4.00 over its 4-year data history and
has helped Honda Motor Company tie for first place among all
automobile manufacturers in the Early 2011 Auto
Reliability Grade Point Averages. See the
table below. |
The following table provides the reliability Grade Point Averages (GPAs)
for each of the automobile manufacturers with significant sales in North
America. Each manufacturer's GPA is an average, unweighted by sales, of
those of its motor vehicle products that appear in the tables of the
Consumer Union's Consumer Reports: New Car Buying Guide: 2011 and
the April 2011 issue of the Consumer Reports magazine. The Average
GPA for each car company is the average of the
Average GPAs of its products. The Average
Minimum GPA for each manufacturer is the average of the
Minimum GPAs of its models. The Reliable
Two, Toyota Motor Corporation and Honda Motor Company, appear first in the
table, because of their rather singular stature; the remaining manufacturers
are listed alphabetically.
Letter grades are determined thusly: A if the GPA is 3.50 to
4.00, B if the GPA is 2.50 to 3.49, C if the GPA is 1.50 to 2.49, D if
the GPA is 0.50 to 1.49, and F if the GPA < 0.50.
GPAs for 4 age ranges are given so that the visitor may
examine more thoroughly the one that is of greater interest to
him/her, if such there be.

Notice that (1) Toyota and Honda products dominate the upper end of the reliability
spectrum in the outer years, as well as for younger vehicles, (2) Toyota and
Honda tied for the top spot in 2011, and (3) Hyundai has leaped past Chrysler, Ford, and General Motors.
The following bar chart provides a graphic depiction of the early overall 2011 Auto
Manufacturer Reliability GPAs.

Caution |
There are very few data values for
Land Rover; consequently, its reliability GPA and
ranking may not be accurate. |

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
"Much Better Than Average" rating, 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 Grade
Point Average (GPA) is an average of the Grade Points and is computed using
Microsoft's Average(a:b,[c:d],...) function.
