This study conducted an empirical analysis on the effect of electric vehicle product quality on satisfaction, electric vehicle brand and loyalty to consumers who have purchased and used electric vehicles in the Chinese electric vehicle market, and analyzed the mediating effect of customer satisfaction between electric vehicle product quality and customer loyalty.
 Garvin (1984) reviewed prior research using the eight components of the proposed product quality and established questionnaires on the eight components, and conducted a 12-day survey from August 07 to 18, 2023. The actual questionnaire collected the results of a total of 266 people, excluded 41 copies without experience in using electric vehicles, 18 invalid questionnaires, and analyzed the relationship between customer satisfaction and customer loyalty using 207 valid questionnaires.
 According to the results of the analysis, it was confirmed that core functions, appearance characteristics, reliability, aesthetics, and cognitive quality had a positive (+) significant effect on customer satisfaction in the product quality model, and core functions, reliability, consistency, and cognitive quality had a positive (+) significant effect on customer loyalty. In addition, customer satisfaction had a positive (+) effect on customer loyalty. In addition, customer satisfaction has a mediating effect in the relationship between core performance, reliability, cognitive quality, and customer loyalty of electric vehicle product quality. Finally, core performance, reliability, and cognitive quality, which are components of electric vehicle product quality, have all been shown to have a positive (+) effect on customer satisfaction and customer loyalty, so it is necessary to increase core performance, reliability, and cognitive quality to improve customer satisfaction and customer loyalty.
