Car Brands - Worst Brands of MY 2006

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

This page lists the worst car brands 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 Brands by Share of CR's 2012 list of 2006 Cars to Avoid

The 10 worst car brands of 2006 by share of CR's 2012 list of 2006 Cars to Avoid are listed below, together with their corresponding shares.

  • Chevrolet line, accounting for 14.5% of 2006 Cars to Avoid in 2012
  • Dodge line, accounting for 7.9%
  • Volkswagen line, accounting for 6.6%
  • GMC line, accounting for 6.6%
  • Nissan line, accounting for 6.6%
  • Mercury line (now defunct), accounting for 5.3%
  • Chrysler line, accounting for 5.3%
  • Jeep line, accounting for 5.3%
  • Mercedes-Benz line, accounting for 5.3%
  • Ford line, accounting for 5.3%
The Chevrolet brand leads the list of the worst in model years 1985, 1986, 1993, 1995, 1996, 1997, 1998, 1999, 2000, 2001, 2002, 2003, 2005, and 2006.
 
The Ford brand leads the list of the worst in model years 1993 and 1994.
 
Noteworthy is that although the Toyota line has more than 50% more 2006 models rated in Consumer Reports' 2012 reliability tables than does the Chevrolet line (reflecting U.S. consumers' growing disinclination to buy GM vehicles and General Motors' resulting market share reduction), the Chevrolet line accounts for 14.5% of 2006 Cars to Avoid in 2012 and the Toyota line accounts for none.
 
The brands that account for the remaining nearly 32% of 2006 cars on CR's 2012 list are Pontiac (now defunct), Mini, Cadillac, Buick, Kia, BMW, Subaru, Hummer, Land Rover, Saturn (now defunct), Audi, Lincoln, Porsche, and Mazda.
 
The following bar graph depicts each brand's share of the 2006 Used Cars to Avoid in 2012 at an approximate age of 5 ½ years.

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

For this quality measure, we divide the brand'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 15 worst 2006 brands by this quality measure are, in descending order (worst first):

  • Hummer line (now defunct), with a dividend-divisor ratio of 1/0
  • Land Rover line, with a dividend-divisor ratio of 1/0
  • Pontiac line (now defunct), with a quotient value of 3.00 based on 1 rated model
  • Mercury line (now defunct), with a quotient value of 2.00 based on 2 rated models
  • Volkswagen line, with a quotient value of 1.67 based on 3 rated models
  • Mini line, with a quotient value of 1.50 based on 2 rated models
  • Chrysler line, with a quotient value of 1.00 based on 4 rated models
  • Buick line, with a quotient value of 1.00 based on 2 rated models
  • Saturn line (now defunct), with a quotient value of 1.00 based on 1 rated model

Note that the quotient ratio is large for all of the 15 Worst Brands.
 
All of the brand quotients for model year 2006 are depicted in the following bar graph.
