You might assume that when your car breaks down, you can take it anywhere you want to get it fixed. Increasingly, that assumption is wrong — not because of any shortage of mechanics, but because of deliberate choices made by automakers about who gets access to the information needed to repair modern vehicles.
This is the right to repair fight, and it directly affects how much you pay and who you can trust with your car.
What "Data Lock" Actually Means
Modern cars are computers on wheels. Diagnosing most problems requires connecting to the vehicle's onboard systems — not just plugging in a basic code reader, but accessing manufacturer-specific data streams, live sensor readings, and calibration tools.
Automakers control that access. They decide:
- Which shops can connect to proprietary diagnostic systems
- What data gets shared with independent technicians versus dealer technicians
- Whether a repair completed by an independent shop can be properly validated by the vehicle's software
When a manufacturer withholds that access from independent shops, those shops can't do certain jobs — or can only do them improperly. The work effectively gets pushed to dealerships, which charge more and operate in a less competitive market.
Telematics Makes It Worse
Telematics — the always-on data connection modern vehicles maintain — gives manufacturers a real-time feed of your car's health. They know when something is wrong before you do.
The problem: that data currently flows to manufacturers, who can direct customers back to dealerships through in-app notifications and recommendations. Independent shops don't have the same direct line to that information. The manufacturer becomes the first — and often only — voice in the room when your car needs attention.
"When a manufacturer can alert you to a problem, tell you which dealer to visit, and control what information your independent shop can access, that's not a level playing field. That's a funnel."
The REPAIR Act and Where It Stands
The REPAIR Act (Right to Equitable and Professional Auto Industry Repair Act) is the current federal legislative push to require automakers to share vehicle data with independent shops on fair and equal terms. As of early 2025:
- The bill has gained dozens of cosponsors in Congress
- It has not yet advanced to a full floor vote in either chamber
- Industry lobbying from automakers has been substantial and well-funded
The GAO released findings documenting that independent shops are being disadvantaged by unequal data access — a validation of what repair advocates have been arguing for years.
Maine and the State-Level Model
Maine's right to repair law is the furthest-advanced state-level effort and a proof of concept for what federal legislation could accomplish. The Massachusetts right to repair law — focused on telematics specifically — has been tied up in legal challenges since it passed in 2020, illustrating how hard manufacturers fight to maintain their data advantage.
What Consumers Can Do Right Now
- Support independent shops — They need your business to survive while the policy fight plays out
- Contact your representatives — The REPAIR Act needs votes; constituent calls move legislation
- Know your options before something breaks — Find an independent shop you trust now, not when you're in a bind and a dealership is the only one who can access your car's systems
- Pay attention to what your car's app is telling you — Manufacturer-directed notifications aren't necessarily bad advice, but they're not neutral either
EthicalMechanic.org is built on the belief that consumers deserve real choices in who repairs their vehicles. The right to repair fight is ultimately a fight about market competition — and you're the one who pays when that competition disappears.
