This research aimed to examine the influence of service quality and customer satisfaction on customer loyalty at JPM Speed Workshop Maumere. The research was motivated by the decline in the number of customers at JPM Speed Workshop Maumere during the 2023–2025 period, as well as the results of a preliminary survey indicating that the level of customer loyalty remained relatively low. Customer loyalty was an essential factor in sustaining the operations of an automotive repair workshop, as it was closely associated with repeat purchases, customers’ willingness to recommend the workshop to others, and their resistance to competitors’ influence. Therefore, efforts to enhance customer loyalty through improvements in service quality and customer satisfaction were considered necessary. This research used a quantitative method with descriptive and associative approaches. The research variables consisted of service quality as the first independent variable (X₁), customer satisfaction as the second independent variable (X₂), and customer loyalty as the dependent variable (Y). The population comprised all customers of JPM Speed Workshop Maumere. Data were collected using questionnaires distributed to the respondents. The data were analyzed using descriptive analysis, classical assumption tests, multiple linear regression analysis, the t-test (partial), the F-test (simultaneous), and the coefficient of determination to test the research hypotheses. The results of the research indicated that service quality and customer satisfaction had a positive and significant effect on customer loyalty, both partially and simultaneously. The better the service quality provided and the higher the level of customer satisfaction, the greater the customer loyalty toward JPM Speed Workshop Maumere. These findings were expected to serve as valuable input for the workshop management in improving service quality and customer satisfaction to maintain and strengthen customer loyalty amid increasingly intense business competition.
