Car Makers - Worst Manufacturers of MY 2006

The Car Manufacturers with the Least Reliable and Durable Cars of Model Year 2006 by CR's 2012 List of Used Cars to Avoid

This page lists the worst car manufacturers of model year 2006 by two measures, both of which employ Consumer Reports' list of Used Cars to Avoid. Both measures use the 2006 models on the 2012 list of Cars to Avoid, when the 2006 cars were about 5 ½ years old. 

2006's Worst Car Makers by Share of CR's 2012 list of 2006 Cars to Avoid

The 7 worst car manufacturers of 2006 by share of CR's 2012 list of 2006 Cars to Avoid are listed below, together with their corresponding shares.

  • General Motors Corporation (renamed Motors Liquidation Company in a bankruptcy proceeding), accounting for 34.2% of 2006 Cars to Avoid in 2012
  • Chrysler Group, accounting for 18.4%
  • Ford Motor Company, accounting for 11.8%
  • Volkswagen AG, accounting for 7.9%
  • BMW AG, accounting for 6.6%
  • Nissan Motor Company, accounting for 6.6%
  • Mercedes-Benz, accounting for 5.3%
General Motors Corporation is first among the worst in model years 1985, 1986, 1987, 1988, 1989, 1990, 1991 (tied for first), 1992, 1993, 1995 (tied for worst), 1996, 1997, 1998, 1999, 2000, 2000, 2001, 2002, 2003, 2004, 2005, and 2006.
 
Chrysler Corporation/Chrysler Group/Chrysler LLC/Chrysler Group LLC is first among the worst in 1991 (tied for first), 1994, and 1995 (tied for worst).
 
Ford Motor Company is first among the worst in 1991 (tied for first).
 
General Motors Corporation, with debts far exceeding assets and declining sales, filed a bankruptcy petition in 2009 and changed its name to Motors Liquidation Company. A newly incorporated and U.S.-financed company took the name General Motors Corporation and acquired many of the assets, including the old manufacturing plants, as well as many of the employees, of Motors Liquidation Company, now mainly a shell.
 
Worthy of note is that Toyota Motor Corporation, with a number of rated models identical to that of General Motors, had not one 2006 model among the 2012 list of Used Cars to Avoid, while General Motors accounted for 34.2% of the Worst.
 
The following bar graph depicts each car company's share of the 2006 Used Cars to Avoid in 2012 at an approximate age of 5 ½ years.

This is a bar graph of the 2006 model shares of the 12 worst car manufacturers of 2006 by CR’s 2012 list of 2006 Used Cars to Avoid. Chart by James Benjamin Bleeker, 10 March 2012.

2006's Worst Car Manufacturers by Number of Manufacturer's 2006 Cars to Avoid Divided by All of Its 2006 Cars Rated in 2012

For this quality measure, we divide the car maker's number of 2006 models on CR's 2012 list of Used Cars to Avoid by the number of its 2006 models rated in CR's 2012 Reliability Tables. This computation is done with the intent to garner a rough estimate as to how likely a brand's models will be among the Cars to Avoid at about 5 ½ years.

The 10 worst 2006 car manufacturers by this quality measure are, in descending order (worst first):

  • Land Rover (then part of Ford), with a dividend-divisor ration of 1/0
  • Volkswagen AG, with a quotient value of 1.00 based on 6 rated models
  • General Motors Corporation, with a quotient value of 0.90 based on 29 rated models
  • Chrysler Group, with a quotient value of 0.88 based on 16 rated models
  • Mercedes-Benz, with a quotient value of 0.80 based on 5 rated models
  • BMW AG, with a quotient value of 0.56 based on 9 rated models
  • Kia Motors Corporation, with a quotient value of 0.50 based on 4 rated models
  • Ford Motor Company, with a quotient value of 0.45 based on 20 rated models
  • Porsche AG, with a quotient value of 0.33 based on 3 rated models
  • Nissan Motor Company, with a quotient value of 0.33 based on 15 rated models
All of the car company quotients for model year 2006 are depicted in the following bar graph.

This s a bar graph of 2006’s worst car manufacturers by number of the company’s 2006 Cars to Avoid in 2012 divided by all of its 2006 cars rated in Consumer Reports’ April 2012 Reliability Tables. Chart by James Benjamin Bleeker, 10 March 2012.

The Vibe, a rebadge of the Matrix, is not included in the above computations.
 
Note that the Ford Motor Company's fraction is half of that of General Motors, despite a similar number of rated models, 20 and 29, respectively.
