Quality Grades are a rating of reliability and durability of car and light truck models within the Chevrolet brand and are based on Consumer Reports' worst vehicle tables and its reliability charts/tables.

Chevrolet's Quality Grades

Chevrolet's Quality Grades for model years 1985-1989, 1990-1994, 1995-1999, 2000-2004, 2005-2006, and 1985-2006 are given below.

  Model Years Quality Grade
xxxxx 1985-1989    Worst
  1990-1994    Worst
  1995-1999    Worst 
  2000-2004    Worst
  2005-2006    Worst
  1985-2006    Worst

Possible Quality Grades, from best to worst, are: Excellent, Better, Good, Middling, Poor, Worse, and Worst. The Chevrolet brand falls at the very bottom of the Quality Grade spectrum for the overall model-year period 1985 to 2006. For contrast, the Quality Grades of the Toyota brand (with the best record) are all Excellent.

The criteria for each grade for each model-year period are given near the bottom of this page.

Chevrolet's U.S. New Car Market Shares

Chevrolet's U.S. new car market shares for calendar years 1989, 1994, 1999, 2004, and 2009, together with its changes in market share from 1985 to these years and its changes in market share from 2000 to 2004 and 2009, are given next. Market shares are rounded to the nearest hundredth.

 

Calendar Year


U.S. New Car Market Share
Percent Change in U.S. Share from 1985 Percent Change in U.S. Share from 2000
xxxx 1989 0.14 -10%
  1994 0.11 -27%
  1999 0.10 -33%
  2004 0.12 -21% 20%
  2009 0.10 -34% -1%

The decline in Chevrolet's U.S. new car market shares is slower than both Buick's (down 86% from 1985 to 2009) and Cadillac's (down 57% from 1985 to 2009), suggesting that Chevrolet owners have fewer information acquisition skills than their Buick and Cadillac brethren. This points to a very tragic failure of the U.S. public educational system in imparting these skills to manual labor America. While many professionals may acquire information and develop information acquisition skills independent of U.S. public schools, these schools are likely manual labor's nearly exclusive source for gathering meaningful information and developing useful information acquisition skills.

For contrast, from 1985 to 2009 Toyota's U.S. new car market share grew 189%, and from 2000 to 2009 Toyota's grew 65%.

For contrast, Toyota's U.S. new car market shares are plotted as well. In addition, for both brands, a trend line – a linear regression of degree one – is included, as a linear regression often imparts additional useful information.

Reference Info

By convention, cars include sedans, coupes, convertibles, hatchbacks, and wagons, light trucks include SUVs (including crossover), minivans, and pickup trucks, and light vehicles include cars and light trucks.

The requirements for a Quality Grade are given below. In listing the requirements, the following abbreviations are used:

CA = a 6-year-old model entry in CR's Cars to Avoid, also termed Vehicles to Avoid
RT = a 6-year-old model entry in CR's Reliability Tables.

Grades for the 5-model-year groups 1985-1989, 1990-1994, 1995-1999, and 2000-2004 are earned as follows:

Excellent: 0 CAs and at least 21 RTs
Better: 0 CAs and 11 to 20 RTs
Good: 0 CAs and 5 to 10 RTs
Middling: 1 or 2 CAs and 10 or more RTs
Poor: 3 to 5 CAs
Worse: 6 to 8 CAs

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.
