The Federal Trade Commission has finalized rules requiring all automakers to provide independent repair shops with the same diagnostic tools, software, and technical information available to franchised dealerships, effective January 2027.
Rule Requirements
The regulation addresses the growing practice of automakers restricting access to onboard diagnostic systems, particularly in electric vehicles with software-dependent components.
- Full OBD-III port access required for all diagnostic functions, not just emissions
- Software updates must be available through standardized interfaces
- Telematics data must be accessible to vehicle owner-designated repair providers
- Penalties of up to $50,000 per violation per vehicle
Industry Impact
The American Automobile Association estimates the ruling will save consumers an average of $1,200 per year in repair costs by restoring competition in the $300 billion automotive repair market. Automakers have lobbied against the rule, citing cybersecurity concerns.
