California Governor Gavin Newsom has signed Leno's Law into effect, marking a major shift in how the state handles vehicle right-to-repair issues. The legislation, named after Senator Dave Jones, removes significant barriers that have prevented independent repair shops from accessing diagnostic and repair information for modern vehicles.
The law requires automakers to provide independent repair facilities with access to the same diagnostic tools, repair data, and software that franchise dealerships receive. This applies to model year 2018 and newer vehicles sold in California. Manufacturers must grant access through a standardized, affordable platform that doesn't lock shops into proprietary systems or impose unreasonable fees.
Newsom's signature comes after a critical amendment smoothed passage through the California Senate. That provision addressed manufacturer concerns about cybersecurity and data privacy by including safeguards that prevent unauthorized access to vehicle systems while still guaranteeing independent technicians can perform repairs. The amendment proved decisive. It gave both consumer advocates and industry representatives enough confidence to stop blocking the bill's advancement.
The legislation targets a real problem in the automotive repair market. For decades, independent shops have faced an information gap. Automakers control access to proprietary diagnostic software, service manuals, and repair procedures. Owners who take vehicles to non-dealer shops often find technicians unable to diagnose complex issues or perform warranty-covered repairs. This arrangement has forced many vehicle owners into expensive dealership service, where labor rates run 30 to 50 percent higher than independent shops.
Leno's Law directly challenges this model. Manufacturers like General Motors, Ford, Stellantis, and BMW will now face requirements to license repair information to independent facilities at reasonable rates. The law does not mandate free access but instead sets parameters around affordability and standardization. A shop cannot be forced to purchase a manufacturer's proprietary diagnostic platform when an independent equivalent exists.
The fight for right-to-repair extends beyond California. Similar legislation has moved through other states and gained traction at the federal level. The FTC has investigated automaker repair restrictions under antitrust law. Massachusetts voters approved a right-to-repair ballot measure in 2020. New York passed comparable legislation in 2022. These parallel efforts reflect growing frustration with manufacturer control over repair markets and data.
For independent repair shops, Leno's Law represents validation and practical relief. The repair industry employs millions and generates billions in revenue annually across California. Many of these shops have faced bankruptcy or closure when manufacturers restricted access to diagnostic information. Shop owners have testified before lawmakers that they cannot compete without equal access to repair data.
Automakers initially opposed the legislation, citing concerns about cybersecurity and intellectual property. They argued that unrestricted data access could enable hackers to exploit vehicle systems or compromise customer privacy. The amendment addressing these concerns apparently satisfied those objections. Major manufacturers did not actively campaign against the bill once the cybersecurity language was added.
Implementation will take months. Regulators must establish specific rules around what constitutes "reasonable" access fees, how quickly manufacturers must respond to information requests, and what penalties apply for non-compliance. The California Department of Consumer Affairs will oversee enforcement.
This law reshapes California's automotive service landscape. Vehicle owners gain genuine repair choice. Independent shops gain competitive footing. The dealership network loses its information monopoly. Expect other states to follow California's lead as Leno's Law demonstrates that right-to-repair can balance manufacturer concerns with consumer interests.
