Right-to-repair is in the news because of the federal REPAIR Act and similar state laws in Massachusetts and Maine. A lot of the coverage focuses on independent repair shops and aftermarket parts. What gets less attention is how these laws fit with two other things: factory warranties and vehicle service contracts.

This article walks through how the three pieces — the REPAIR Act, the Magnuson-Moss Warranty Act, and vehicle service contracts — relate to each other. It is informational. We are not telling you what to do. We are showing you what each set of rules covers and how they fit together.

Three Different Things, Often Confused

Start with definitions. Three terms come up over and over in this conversation, and they mean different things.

A warranty is a written promise from the carmaker that comes with the vehicle. You do not pay extra for it. The factory warranty on a new car is a warranty. Federal law — the Magnuson-Moss Warranty Act of 1975 — sets the rules for written warranties on consumer products.

A vehicle service contract (VSC) is a separate paid agreement. It usually covers repairs after the factory warranty runs out. A dealer, a third-party administrator, or an insurance company sells it. Federal warranty law does not treat a VSC as a warranty. The FTC consumer guidance draws the line clearly: "An auto service contract or extended warranty is not a warranty as defined by federal law, because you buy it separately; it's not included when you buy a car."

Right-to-repair laws are about something else entirely. They are not about whether your repair is covered. They are about whether you and your repair shop can get the data, tools, and parts needed to do the work in the first place. The federal REPAIR Act and the state laws in Massachusetts and Maine are right-to-repair laws.

What the Magnuson-Moss Warranty Act Already Does

Before talking about the REPAIR Act, it helps to know what federal law already requires. The Magnuson-Moss Warranty Act has been the rule of the road for warranty disclosures and tying restrictions for fifty years.

The full text is at 15 U.S.C. §§ 2301-2312. The most-cited part for repair-shop choice is the anti-tying rule in 15 U.S.C. § 2302(c). That section says a carmaker cannot tie the warranty to a specific brand of parts or service. There are two narrow exceptions. The first is if the carmaker provides the parts or service for free. The second is if the FTC approves a waiver. In practice, the FTC almost never grants waivers.

The FTC's consumer-facing guidance puts it plainly: "The manufacturer or dealer must prove the aftermarket or recycled part caused the damage before they can deny warranty coverage." In other words, a dealer cannot reject a warranty claim just because the customer used an independent shop or a non-branded part. The dealer has to show that the third-party part actually caused the problem.

This is what people mean when they say Magnuson-Moss already protects shop choice for warranty work. It does — for warranty work, on the factory warranty. But Magnuson-Moss does not regulate vehicle service contracts in the same way. It defines them as a separate category, and most of the rules that govern VSCs come from state law instead.

How VSCs Are Regulated

Vehicle service contract rules are set state by state. Most states cover VSCs through their insurance department, the attorney general's office, or a consumer protection agency. There is no federal rulebook for VSCs. State insurance codes govern insurance, but there is no equivalent for VSCs at the federal level.

VSC rules typically cover:

Whether the customer can use an independent shop for VSC-covered repairs is set by the contract itself, not by Magnuson-Moss. Some VSCs require approved-network repair shops. Others let the customer pick. State law sometimes adds rules on top — for example, requiring contracts to disclose whether shop choice is restricted. Our state-by-state VSC compliance guide walks through the specific differences across all 50 states.

What the REPAIR Act Would Change

The federal REPAIR Act (H.R. 1566 in the House, S. 1379 in the Senate) does not directly regulate vehicle service contracts. It focuses on two things: access to vehicle-generated data, and the ability of aftermarket parts makers to produce parts that fit modern vehicles.

But its effects would still touch the VSC industry in a few ways.

The repair shop network would be different. A VSC pays for covered repairs at a network of approved shops. Today, an independent shop's ability to do those repairs depends partly on whether it can get the carmaker's diagnostic codes, calibration tools, and procedures. As cars become more software-driven, more of those tools are kept inside the carmaker's system. If the REPAIR Act passes, more independent shops would have the data to handle modern repairs. That could expand the pool of qualified shops a VSC administrator can route claims to. It does not change the contract itself.

Aftermarket parts in claim work. The REPAIR Act would prohibit carmakers from blocking the production of aftermarket parts. If a VSC is repaired with an aftermarket part, that is a contract-level question: the contract terms set out whether OEM, OE-equivalent, or aftermarket parts are required. Magnuson-Moss already restricts a carmaker from voiding the original factory warranty over an aftermarket part. The REPAIR Act would make sure those parts can keep being made.

Vehicle data and claim verification. Some claim work uses vehicle-generated data. Examples include the mileage at the time of failure, fault codes captured by the car's computer, and service history pulled from the car. The REPAIR Act would expand owner access to that data. It would also let owners share it with their chosen repair shop. For a TPA processing a claim, that means more data may be available to verify coverage. It also means more parties have access to data that used to live only in carmaker systems.

State Laws That May Affect VSC Workflows

State right-to-repair laws are narrower in scope than the federal REPAIR Act. They focus mostly on telematics — the data the car transmits wirelessly. But because they're already in effect, they're the more immediate operational question for VSC administrators today.

The Massachusetts Data Access Law has been on the books since the 2020 ballot initiative passed. It applies to model year 2022 and later vehicles sold in the state. Carmakers selling those vehicles in Massachusetts are required to provide a standardized open-access platform for vehicle telematics data. While the law was being challenged in court, some carmakers — including Subaru — disabled telematics in vehicles sold in Massachusetts rather than build the platform.

That has practical effects on claim work. If the connected-vehicle features are disabled, certain remote diagnostic tools and services may not work the same way in those vehicles. As the legal challenge moves toward a possible settlement in 2026, the operational picture in Massachusetts could change again.

Maine's right-to-repair law took effect on January 5, 2025. The law's structure is similar to the Massachusetts version. Implementation has been slow because the independent administrator that the statute requires has not yet been established. The Maine Legislature reconvened in January 2026 to work through amendments.

Where the Three Frameworks Overlap and Differ

To put it all together:

The three frameworks operate on different parts of the vehicle's life cycle. Magnuson-Moss applies during the factory warranty. VSCs apply after. Right-to-repair laws apply across the whole life of the vehicle, but only at the technical level — they're about access, not coverage.

What to Watch in 2026

Three procedural and legal moments are on the calendar for the rest of 2026:

  1. The full House Energy and Commerce Committee vote on H.R. 1566. The bill cleared the subcommittee on February 10, 2026. The next vote, in the full committee, has not yet been scheduled at the time of writing.
  2. The September 30, 2026 Surface Transportation Reauthorization deadline. Supporters are pushing to attach the REPAIR Act to the larger transportation bill. If it gets attached and the larger bill passes, the REPAIR Act becomes federal law.
  3. The Massachusetts settlement. The Alliance for Automotive Innovation and the Massachusetts Attorney General agreed in February 2026 to pause appellate proceedings to consider a settlement. If they reach one, it could change how the Massachusetts Data Access Law is enforced — and could become a model for other states.
