ADAC has published results of a car reliability survey (2013), targeting interventions requiring the mobile service between 2007 and 2012. German brands ranked first almost in all classes in terms of reliability, with the lowest defect rate.
ADAC presented a breakdown statistics collected from 2.6 million interventions performed in 2012, after which they analyzed more than 500,000 vehicles. The results surprised even the Germans, the first edition in which the German car manufacturers getting first in almost all tested classes.
ADAC Car Reliability Survey 2013
In 2012, the most common problem that required the ADAC intervention was located on the electrical system. We are talking about malfunctioning or discharged accumulators, and ADAC representatives say that the problems were caused by mistakes in the design of the electrical system or the location of the battery pack in a unsuitable position. For example, ADAC said the vehicles with a start-stop system require a special battery, AGM, whose life is significantly reduced when fitted in the engine compartment and gets overheated.
The vehicles that were verified by ADAC were no older than six years, and were considered only the cars whose technical specification remained unchanged for at least three consecutive years and who had at least 10,000 copies sold per year, only 93 models being eligible for the 2013 edition of the reliability survey conducted by the ADAC. There were only considered technical defects that have required ADAC intervention at the request of the owners, not being taken into account accidents or other similar road incidents.
2013 ADAC Car Breakdown Statistics
A dozen models entered in the 2013 ADAC breakdown statistics as being particularly poor. With the verdict “less reliable”, including popular vehicles like Fiat Ducato, Ford Mondeo and VW EOS were evaluated. Thus, the general breakdown susceptibility of all vehicles has improved steadily since the introduction of the ADAC breakdown statistics in 1978, however, the current analysis revealed that striking deficiencies remain.
Number one annoyance is the battery
Every third malfunction in 2012, even at young vehicles, is due to a faulty or discharged battery. Reasons for this often flaws are in the design of electric vehicle management. For example, vehicles with start-stop system usually require a special AGM starter battery. If it is installed in the engine compartment, it can get too hot and then easily broken.
Construction defects affect not only the expensive premium products. Also technically simpler cars like Honda Jazz and Chevrolet Matiz land far behind in the reliability values. Particularly in this case, they are often so-called “penny parts” savings.
The fact that there is an alternative, proves Nissan Micra, which moves in the same price category. The Japanese car is in the ADAC breakdown statistics in 2013 as the best small car with a clean slate that blooms far ahead.
Results Overview – The evaluation procedure of the ADAC car breakdown statistics 2013
First, the breakdown figures for each vehicle model and year of registration are determined.
In the above table we have the values, in columns, under the annual numbers (each upper limit). The higher the breakdown figure turns out, the worse the purpose grade is. The evaluations are distributed linearly. The ranking of individual models is derived from the average number of individual grades for each year.
