The 2025 U.S. OEM ICE App Report, released by J.D. Power, evaluates owner satisfaction with mobile apps for internal combustion engine (ICE) vehicles. It highlights that nearly 80% of ICE vehicle owners use the OEM-provided app, yet engagement remains low, with only 27% identifying as frequent users. The report identifies key areas affecting satisfaction, including connectivity issues, slow response times, and unintuitive interfaces. Owners express a desire for essential features to be easily accessible within the app. The report ranks MINI highest among mass market brands and My BMW highest among premium brands in customer satisfaction. The findings are based on a survey of over 2,100 ICE vehicle owners and an assessment of app functionalities, revealing trends in app usage and feature desirability. The report underscores the importance of reliable connectivity and user-friendly design in enhancing the overall app experience for vehicle owners.
