Legislative bill overview

HD 1300 amends Massachusetts' right to repair law for motor vehicles by requiring manufacturers to provide clearer disclosure notices to consumers about their data rights. The bill specifies what information must be included in these notices and when they must be provided to vehicle owners.

Why is this important

As vehicles become increasingly connected and data-generating, consumers need transparent understanding of what diagnostic and performance data manufacturers collect, how it's used, and what access rights owners have. Clear disclosure requirements help prevent information asymmetries between manufacturers and vehicle owners and support informed decision-making about data privacy.

Potential points of contention

  • Manufacturer compliance costs: Automakers may argue that standardized, detailed disclosure requirements increase administrative and compliance expenses
  • Data collection scope uncertainty: Disagreement over which vehicle data should be covered and how broadly "diagnostic data" is defined could affect practical implementation
  • Disclosure effectiveness: Questions about whether written notices alone meaningfully inform consumers, or whether additional mechanisms (digital dashboards, simplified summaries) are needed
