This study examines post-purchase behaviour and customer satisfaction among hybrid automobile owners in Sri Ganganagar District, Rajasthan. With hybrid vehicles gaining popularity in India, understanding consumer experiences is crucial for manufacturers and policymakers. A quantitative survey of 200 hybrid car owners assesses satisfaction, brand loyalty, and word-of-mouth recommendations. Data were analyzed using Cronbach’s Alpha, T-tests, and ANOVA. Results indicate that fuel efficiency and after-sales service drive satisfaction (76% report high satisfaction), but high maintenance costs and limited service centers create challenges. Brand loyalty is evident in 62% of respondents, with 81% recommending hybrids. Addressing service infrastructure and costs is vital for enhancing satisfaction and supporting Rajasthan’s hybrid market growth, contributing to sustainable mobility.
