This page has been updated to include the data that became available in 2006.

Note that Reliability Grades for model year 2003 are based on one year of data. Consequently, the Reliability Grades for individual models of that year are more subject to statistical fluctuation. These early data have been provided as several visitors have expressed interest in Grades of a more current model year; however, a better guide to the reliability of more current, and the most current, model years are likely the five-year averages.

To review the Percentranks and Percentrank averages upon which the grades are based and/or the color coding for the cells, click here to go to Table I-GMCRP: GMC Reliability Percentranks by Model and Model Year, with Line, Manufacturer, Big Three, Toyota, Honda, Reliable Two, and Ten Year and Five Year Averages.

The Item Numbers in the above table are the same as the Item Numbers in the main table, Table I-MVRGH: Reliability Grades - High Standards for Motor Vehicle Models, Lines, Manufacturers, the Reliable Two, the Top Four, and the Big Three and for Model Years 1988 to 2003.

Advisory: GMC is a division of General Motors Corporation.
