A bipartisan federal bill to open vehicle diagnostic data to independent repair shops cleared a key congressional hurdle in February 2026, accelerating a legislative battle that has simultaneously intensified across multiple state capitols as over-the-air software updates increasingly lock proprietary vehicle data inside OEM-controlled systems.
Background
The proliferation of OTA software updates has deepened the divide between automakers and the independent repair ecosystem. OTA systems allow manufacturers to remotely deliver firmware updates, patches, and new features to vehicles without requiring a dealership visit, but the same wireless architecture that enables remote updates also routes diagnostic and mechanical data through OEM-controlled cloud infrastructure-restricting independent shops' ability to diagnose and service modern vehicles.
According to a 2024 independent survey cited by the Auto Care Association, 63% of independent repair shops reported experiencing a restriction on repair data daily or weekly, and vehicle data limitations cost independent repair shops an estimated $3.1 billion each year. The aftermarket sector represents significant repair volume: according to MEMA Aftermarket Suppliers, 70% of out-of-warranty vehicle repairs are performed outside of the dealer network.
The current debate traces back to a 2014 national memorandum of understanding between automakers and repair trade associations that standardized access via the OBD-II port but explicitly excluded wireless telematics-a technology that has expanded dramatically since.

On February 10, 2026, the House Energy and Commerce Subcommittee on Commerce, Manufacturing, and Trade voted to advance the Right to Equitable and Professional Auto Industry Repair (REPAIR) Act, H.R. 1566, to the full House Energy and Commerce Committee for consideration. Introduced in February 2025 by Representative Neal Dunn (R-Fla.) with bipartisan co-sponsors, the bill would require OEMs to provide vehicle owners, independent repair facilities, and aftermarket parts manufacturers with access to vehicle-generated diagnostic data on the same terms-and through the same methods, including wireless telematics-as that data is made available to manufacturers' own dealer networks.
According to a July 2025 national poll cited by the Auto Care Association, more than 83% of Americans support the REPAIR Act, with 84% of Republicans and 82% of Democrats in favor. "We need to get this done right and get this done now," Representative Dunn said during the subcommittee hearing, according to the Auto Care Association.
At the state level, a Massachusetts federal district court issued a pivotal ruling in February 2025. U.S. District Court Judge Denise Casper dismissed the remaining counts in a lawsuit brought by the Alliance for Automotive Innovation challenging the Massachusetts Data Access Law, which requires that model year 2022 and newer vehicles utilizing a telematics system be equipped with an interoperable, standardized open-access platform making mechanical data available to consumers and their chosen independent repair facilities. The Alliance for Automotive Innovation said the ruling "will introduce potential security risks to our customers and their vehicles" and indicated it would weigh an appeal. In July 2025, the Alliance appealed the district court decision to the U.S. Court of Appeals for the First Circuit, with a ruling potentially expected before the end of 2026.
Maine and Wisconsin have also moved to expand telematics data access for independent repairers. Maine voters approved a ballot initiative in November 2023 requiring OEMs to equip vehicles with an interoperable, standardized, owner-authorized access platform; the Maine Legislature subsequently amended the law to remove the platform mandate and instead require that telematics-based diagnostic functionality be made available on "fair and reasonable terms" to owners and independent repair facilities. Bills introduced by Wisconsin lawmakers during the 2025-2026 legislative session would follow Maine's lead in mandating access to vehicle-generated telematics data for owners and independent repair facilities.
Opponents, including the National Automobile Dealers Association, argue the federal bill could expose sensitive driver data and create unnecessary regulatory complexity, noting that the legislation permits vehicle-generated data to be sold to third parties with owner consent. In February 2025, the Alliance for Automotive Innovation, the Automotive Service Association, and the Society of Collision Repair Specialists jointly outlined in a letter to Congress their concerns with prior legislative efforts and proposed an alternative Safety as First Emphasis (SAFE) Repair Act.
Independent shops are adapting to navigate current restrictions. Forward-thinking repair businesses are investing in cloud-linked diagnostic tools, technician credentialing programs, and cloud-integrated scan tools capable of interpreting OTA update logs-positioning themselves for a regulatory environment that analysts expect will require broader data access regardless of the federal bill's outcome.
Outlook
The REPAIR Act now moves to the full House Energy and Commerce Committee for further consideration, while its Senate companion, S. 1379, remains before the Senate Committee on Commerce, Science, and Transportation. The First Circuit appeal of the Massachusetts Data Access Law is expected to yield a ruling that could set a precedent for how states structure future telematics access legislation. OEMs face mounting pressure to develop compliant data-sharing architectures even as they continue to contest the scope and cybersecurity implications of proposed mandates.
