American cars compared to Japanese cars, a reliability study

Japanese Cars VS German cars ... Who wins?



American cars compared to Japanese cars - a reliability study.
In this paper we study the reliability of American and Japanese cars by comparing the trend of the emergence of problems in the production years American Car Brands selected in this study are Cadillac, Chevrolet, Chrysler, Dodge, Ford, GMC, Jeep and Lincoln selected the Japanese brands are Acura, Honda, Infiniti, Lexus, Mazda, Mitsubishi, Nissan, Subaru, Suzuki and Toyota 1 shows the total number of problems reported for cars built from 1996 to 2013 for the US and Japanese brands.
Figure 1 Total number of problems reported for 8 and 10 Japanese American brands.
Compare reliability using annual occurrence problem Index Index APO.
Note that Figure 1, newer vehicles tend to have fewer problems reported This is because new cars have been in service for a shorter time To better compare vehicle reliability through years of production, we use the annual index of problem occurrence APO Index annual index of problem occurrence is defined as the total number of problems of all cars built in a given year divided by the number of years of service the result is then normalized to 100 Figure 2 shows the annual index of problem occurrence APO index for all eight US brands and trademarks ten Japanese Notice in Figure 2 that there was a big spike problems for 2010 car model year.
Figure 2 The annual index of 8 American problem of occurrence and 10 Japanese brands.



APO index of all 1996 US and Japanese cars 32.
APO index 1997 US and Japanese cars 35.
APO index 1998 US and Japanese cars 39.
APO index 1999 US and Japanese cars 51.
APO index 2000 US and Japanese cars 61.
APO Index 2001 58 American and Japanese cars.



APO index 2002 US and Japanese cars 68.
APO index 2003 US and Japanese cars 66.
APO index of all 2004 US and Japanese cars 81.
APO index 2005 US and Japanese cars 100.
APO Index 2006 98 American and Japanese cars.



APO index of all the 2007 American cars and Japanese 95.
APO index 2008 US and Japanese cars 78.
APO index 2009 US and Japanese cars 53.
APO index 2010 US and Japanese cars 83.
APO index 2011 US and Japanese cars 60.
APO index of all US cars in 2012 and 60 Japanese.



APO index of all 87 American and Japanese cars in 2013.
Figure 3 shows the annual index of problem occurrence APO Index of eight US brands Notice in Figure 3 that the reliability of American cars has improved steadily since 2005.
Figure 3 The annual index of occurrence of problem 8 trademarks of American cars.
Figure 4 shows the annual index of problem occurrence APO index marks ten Japanese Notice in Figure 4 that the reliability of Japanese cars improved slightly from 2005 to 2009 In 2010, however, Japanese cars were a great retreat in reliability problems reported this year rEACHED highest in history it was no coincidence that in 2010 Toyota, Honda and other Japanese automakers have announced massive recalls for millions of its vehicles sold in America.
