Senate Bill 129 aims to enhance the rights of motor vehicle owners regarding the repair of their vehicles by prohibiting manufacturers from imposing barriers that restrict access to vehicle-generated data, critical repair information, and tools necessary for repairs. The bill mandates that manufacturers provide unrestricted access to this data and information, allowing owners and repair facilities to diagnose, repair, and maintain vehicles without being forced to use specific parts or tools. Additionally, it prohibits manufacturers from requiring owners to waive their right to choose their repair service provider and from recommending specific brands of parts or tools without clear notice of the owner's rights.

The bill also establishes penalties for manufacturers that violate these provisions, with fines of up to $10,000 per violation. It includes a clause that voids any contract terms that attempt to limit the manufacturer's obligations under this new law. Overall, the legislation seeks to promote fair competition in the automotive repair industry and empower vehicle owners with greater control over the maintenance and repair of their vehicles.
