An Act relative to the right to repair motor vehicle data law

This bill amends Massachusetts law to update deadlines and requirements for how vehicle manufacturers must inform owners about data collection and repair rights. It extends the date for certain compliance deadlines from 2022 to 2025 and requires that starting with the 2025 model year, owner manuals include specific information about vehicle telematics systems. The manual must explain what data is collected, how owners can access it via mobile devices, and their right to allow independent repair shops to access that data for diagnostics and maintenance. These changes directly affect car manufacturers and vehicle owners in the Commonwealth by clarifying transparency and access procedures regarding vehicle data.
