Car and Light Truck Reliability Menu and Summary
by James Bleeker

(If you are using the Mozilla Firefox browser, it is best to click the refresh button once, or twice, to ensure that you are viewing the entire page, as it seems that Firefox is graphics and/or data-rich challenged. If you are using Google Chrome, the drop-down menu to the left works only hesitantly. The side menus of site manager's other two auto quality websites www.CarsOnInfo.net and www.CarQualityInfo.net are more Google friendly.)

The reliability section of Auto on Info currently has many pages, some of which are:

AutoOnInfo.net's Car Quality Series, Volume 2: Brand Quality for Model Years 1985 to 2006 and Effect on Brand Market Shares from 1985 to 2009

This volume of AutoOnInfo.net’s car guide series offers consumers and researchers an historical summary of the reliability and durability of car and truck brands and examines how these brands have fared in their U.S. market shares. It uses 6-year-old model entries in Consumer Reports’ Used Car to Avoid – also termed Vehicles to Avoid and Worst Cars, Year by Year – and CR’s reliability charts to ascribe quality grades to automobile brands for model-year groups 1985 to 1989, 1990 to 1994, 1995 to 1999, 2000 to 2004, 2005 to 2006, and 1985 to 2006. In addition to ascribing quality grades to each brand, it provides a chart that plots the number of the brand’s 6-year-old model entries in CR’s vehicles to avoid. To examine the effect that a brand’s reliability and durability has had on sales, two or more charts depicting the brand’s U.S. market shares for calendar years 1985 to 2009 are given. These grades and charts and the author’s comments impart an historical perspective that sheds light on the present condition of surviving vehicle lines and their future prospects, individual and institutional shortcomings, and what effect these may have on the U.S.
