The Worst Minivans in 2011 by James Bleeker

The worst minivans by the 2011 Auto Reliability Grade Point Average (GPA) are:

General Motors Corporation's Chevrolet Uplander, a minivan with a 2011 Auto Reliability GPA of 0.00 and Auto Reliability Grade of a perfect F over a 4-year auto reliability data history,
The Volkswagen Eos, a minivan with a 2011 Auto Reliability GPA of 0.17 and Auto Reliability Grade of F over a 3-year auto reliability data history,
Chrysler's Dodge Grand Caravan, a minivan with a 2011 Auto Reliability GPA of 0.38 and Auto Reliability Grade of F over a 10-year auto reliability data history,
The extended Chrysler Town & Country, a minivan with a 2011 Auto Reliability GPA of 0.38 and Auto Reliability Grade of F over a 10-year auto reliability data history,
General Motors' GMC Safari, a minivan with a 2011 Auto Reliability GPA of 0.39 and Auto Reliability Grade of F over a 4-year auto reliability data history,
General Motors' Chevrolet Astro, a minivan with a 2011 Auto Reliability GPA of 0.39 and Auto Reliability Grade of F over a 4-year auto reliability data history,
The Kia Sedona, a minivan with a 2011 Auto Reliability GPA of 0.60 and Auto Reliability Grade of a very low D over an 8-year auto reliability data history.

General Motors Corporation and the Chrysler Group dominate the list of the worst minivans in 2011, accounting for 5 of the 7 worst. Individually, General Motors accounts for 3 of the worst minivans in 2011, the Chrysler Group - 2, Volkswagen AG -1, and Kia Motor Corporation - 1. Six of the above minivans have a reliability grade of F; one has a reliability grade of D. GM accounts for 3 of the 6 Fs.

These minivans are among the Bottom 30 automobiles offering 3 or more model years of reliability data in 2011.

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. The above GPAs are the Average GPAs given in the table "The Updated 2011 Motor Vehicle Reliability Grade Point Averages (GPAs) and Grades with Reliability GPAs for Four 4-Year Age Ranges and an Overall Average Reliability GPA" on the Updated Auto Reliability Grade Point Averages and Grades page.

The sources for Consumer Reports' ratings are the reliability tables in (1) the April 2011 issue of Consumer Reports, (2) Consumer Reports New Car Buying Guide: 2011, and (3) Consumer Reports Used Car Buying Guide: 2011.

Consumer Reports defines reliability as the infrequency of reported serious problems.
