The Analysis of the Occurrence of Faults in Passenger Cars as an Element of Improving the Management of the Production Process

The main goal of the article was to present the results of the fault analysis on the example of one model of a passenger car “X” during the two-year warranty period. The partial goal was to present the possibilities of using data generated in the mega-process of after-sales service and warranty multi-process in order to streamline production processes in the automotive sector. On the basis of the bibliometric analysis, a cognitive gap was identified, consisting in the lack of publications regarding car failures based on data obtained from warranty repairs in the perspective of improving the car production process. The quantitative study was carried out in 2015–2018 in Poland. The subject of the study identified in the article as intervention was car repairs carried out in the Polish network of authorized services stations (ASO). As a result, repairs analyses, based on the statistical and econometric calculations, the probability of the occurrence of faults was presented, broken down into nine construction groups of passenger cars. Moreover, the possibilities of applying the results of the analysis in the improvement of the production process with the use of data generated in the after-sales process and the warranty multi-process. The following methods have been selected in the study: bibliometric analysis, observation, opinion poll, and statistical and econometric methods.
