Reliability Percentranks: Brand Averages - 1988 to 1998

The Car Reliability Percentrank Averages of the Major Car Lines Sold in North America in Model Years 1988 to 1998

The following table provides the Car Reliability Percentrank Averages for the major car brands with sales in North America from the late 1980s to the late 1990s. Brands are grouped by car manufacturer. The order of the car manufacturers is that found in the original tables of 2002.

The Car Reliability Percentrank Average rates automobile lines of a given model year on a scale from 0.00 (the Worst) to 1.00 (the Best). The Car Reliability Percentrank is based on the reported frequency of serious problems in nearly each trouble spot category used by Consumer Reports.

This measure of car line reliability was one of the first used to rate brands of 6-to-8-year-old motor vehicles from model years 1988 to 1998. It appears here as it has been a popular method for rating the auto quality of a line and helps in narrowing the search for a reliable automobile from the 1990s and late 1980s.

Note that Hyundai Motor Company's early entries in the North American car market were not reliable at all. However, by model year 2009, the average Reliability GPA of Hyundai vehicles had leaped past that of the Detroit Three.

General Motors' brands that are now defunct are Oldsmobile, Saturn, and Pontiac. The Oldsmobile line was disposed of prior to GM's 2009 bankruptcy filing; the Saturn and Pontiac brands died in bankruptcy.

Chrysler Group brands that are now defunct are Eagle and Plymouth. Both died prior to Chrysler's 2009 bankruptcy filing.

Ford Motor Company retired its Mercury brand in late 2010.

Computation

For each model of each model year, each rated Consumer Reports trouble spot category (other than brakes or clutch) is given a numerical value as follows: +1 for a Much Better Than Average rating, +0.5 for a Better Than Average rating, 0 for an Average rating, -0.5 for a Worse Than Average rating, and -1 for a Much Worse Than Average rating. Then a simple average is taken for each model of a model year and the averages of the models for a given model year are placed on a scale of 0.00 to 1.00 using Microsoft's Percentrank function (akin to the percentile function). Then, for each model year, a simple average of the model Percentranks is taken to obtain the Reliability Percenrank Average for each line.

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

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.

Volume 6 of AutoOnInfo.net’s Car Quality Series is intended primarily as an aid to consumers in selecting a vehicle that both is reliable in the short term and provides a prospect of only modest repairs in the long term, and secondarily as an aid to auto industry analysts and reporters. To this end, it provides a list of the 50 Best Cars available in the U.S. in 2014 using the Overall Reliability GPA, AutoOnInfo.net’s standard measure of reliability now for several years, covering model years 2002 to 2013 for ranking pickup trucks, sport-utility vehicles (SUVs), family cars, wagons, small cars, hatchbacks, sport/sporty cars, coupes, convertibles, upscale cars, luxury cars, and hybrids, and includes each car’s reliability GPA and grade and the number of model years upon which the GPA and grade are based. As a further aid, it includes 2014 brand and manufacturer GPAs for comparison and contrast and for better assessing long term performance and ownership expenses. In addition, it offers more than 30 full color charts depicting each brand’s and car company’s share of the 10, 20, 30, 40, and 50 Best Cars and each brand’s and auto maker’s share of the best pickups, best midsize sport-utility vehicles, best small SUVs, best family cars, best wagons, best small cars, best hatchbacks, best sport/sporty cars, best coupes, best convertibles, best upscale cars, best luxury cars, and best hybrids in America. For further study and better understanding of auto quality in North America, it offers 10 charts that display, using a bar graph with an axis value of 2.00 (for quick viewing of how much above or below average a brand’s or auto maker’s  Reliability GPA falls), the 2014, 2013, 2012, 2011, and 2010 Reliability Grade Point Averages of each major brand and manufacturer, as well as a line graph plotting the 2010 to 2014 Reliability GPA ranks of the 6 most prominent manufacturers by U.S. sales.
