The Best Minivan in 2011 by James Bleeker

The V6, front-wheel-drive Toyota Sienna minivan has a 2011 Auto Reliability GPA of a 2.94 over a 10-year data history.

Although not one of the Top 30 autos of 2011, the reliability of the V6, front-wheel-drive Toyota Sienna minivan exceeds all of its competition by a good margin. Its closest competitor is the Honda Odyssey, with a 2011 Auto reliability GPA of 2.44, versus the Sienna's 2.94.

Generally, the reliability of minivans is not good. More than 20% of the 30 worst automobiles of 2011 are minivans.

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.
