Honestly, I would prefer to relativize, to the extent possible, the results of reliability studies such as those published by J. D. Power. Are a few studies somewhat limited, since the concept of reliability has always been based on a limited period in time, that does not always respond accurately to what we understand by reliability, that is to say, that a car is less likely to suffer from problems that lead to its owner at the workshop. In any case, never ceases to amaze us that in the study conducted in Germany marks the fewer problems they suffer were not precisely German, but japanese.
The study of reliability, or J. D. Power 2015 Vehicle Dependability Study (VDS) in Germany, focuses on the problems experienced in the last 12 months for vehicles with an age of between 12 and 36 months. So that the result of each brand is measured under a coefficient that J. D. Power named PP100, or the number of problems experienced per every hundred owners surveyed. J. D. Power believes that a car has suffered a problem analyzing 177 common symptoms.
The average of the industry in Germany in the first study of these characteristics carried out by J. D. Power in the country stood at around 129, practically on the figures thrown out by Volkswagen (a PP100 of 127), and Opel (a PP100 of 131). Only 5 marks were below the mark of the PP100, that is to say, less than a hundred problems per hundred cars. And none of them was German, except that we consider to Skoda – both usufructuaria of the technology and capital of the Volkswagen Group – as a German brand.
The brands that have stood out have been two japanese, Mazda (87), and Mitsubishi (90), closely followed by Skoda (93) and Dacia (96). Toyota (98) also managed to stay under 100 PP100. To meet up with the German brand with a better outcome in this study, we would have to move up to the ninth position, with Porsche (106). MINI (104) would be a the eighth step, and Suzuki (102) and Nissan (103) is found in the seventh and eighth step, respectively. It also surprised a lot of the negative result of Alfa Romeo, with 268 problems per hundred owners surveyed.
J. D. Power highlights the ease-of-brands generalists in order to get some very favorable results, unlike the premium local, as BMW (145), Mercedes-Benz (145) and Audi (158) that exceed the average of problems analyzed in this study.
The study, conducted between April and June of 2015, is based on surveys conducted by J. D. Power to a total of 14.605 owners who purchased their car between April 2012 and march 2014.
The models that are most valued, in their respective segments, have been Opel ADAM, Mazda 3, Skoda Superb, Skoda Fabia and BMW X1.
For more on these results, we recommend a reading of the study published by J. D. Power (see study).
