The ongoing debate about the right to repair is even more nuanced and complex for electric vehicles (EVs) than conventional internal combustion engine (ICE) vehicles. A late-model car is fundamentally no longer a mechanical system. In an EV, there are high-tech battery chemistries, high-voltage hardware, embedded software, thermal management, networked controllers and cloud-connected services. As a result, repair becomes a matter of data access, software authority and verified safety, just as much as it is parts availability.

However, while the nature of repair differs for EVs compared to ICE vehicles, both vehicle types are heavily impacted by repair access, which affects vehicle life, resale value, service availability, insurance claims, aftermarket modifications and more. The repair rights that developed around internal combustion vehicles need modification for vehicles whose most valuable systems are governed by software and calibrated after sale.

Building on existing right-to-repair frameworks

“Right to repair” does what it says on the tin; it means the owner can choose who diagnoses, maintains and repairs a product. In the automotive market, that has meant practical access to service information, diagnostic codes, scan-tool functions, parts, software procedures and tools sufficient for independent competition. The FTC has treated repair restrictions as a consumer-choice and competition issue when manufacturers limit manuals, parts, diagnostic software, tools, telematics or software functions.

Warranty law supports that in a limited way. Under the Magnuson-Moss Warranty Act, a manufacturer generally cannot condition warranty coverage on branded parts or authorized service unless it provides that part or service for free, which helps an owner avoid a false warranty threat, but it does not require access to battery state-of-health data, secure gateway credentials, advanced driver assistance system (ADAS) calibration routines or firmware needed to complete a repair.

The stronger automotive repair-access precedent came from emissions regulation rather than consumer protection law. The U.S. Environmental Protection Agency's 2003 OBD service-information rule required manufacturers to make emissions-related repair information, tools and enhanced diagnostic information available to independent repairers when those resources were available to franchised dealers. That model did not create unlimited access, but parity for repair-relevant functions.

What EV repair adds

EVs remove several routine combustion-engine maintenance tasks. For example, vehicles do not require traditional oil changes, fuel system maintenance, spark plug replacement or emissions checks. However, unlike ICE vehicles, servicing their high-voltage battery systems requires specialized training, so while EV repair may involve fewer recurring service visits, higher-value work often depends on specialized knowledge and controlled software functions.

High-voltage safety is a genuine engineering constraint. The U.S. National Highway Traffic Safety Administration's (NHTSA’s) FMVSS 305a rule defines high voltage as working voltage greater than 30 V AC or 60 V DC and adds requirements for rechargeable energy storage systems. A technician working on a battery pack, inverter, onboard charger or DC fast-charging circuit may face shock hazards, stored energy, isolation faults, coolant intrusion and post-crash risks, so a repair framework that treats those tasks like ordinary mechanical work would misstate the technology at great peril.

Notably, battery data also changes the economics of ownership. A pack may need isolation testing, thermal inspection, leak evaluation, cell-balance information and battery management system data before a shop or insurer can decide whether the vehicle can safely return to service. Battery state of health also affects resale value, warranty decisions and insurance outcomes, yet recent research notes that vehicle-level battery state-of-health measurement lacks a fully standardized method. Without credible access to battery condition, the owner’s right to repair becomes incomplete.

Software adds another constraint, as EVs depend on firmware, controller configuration, charging logic, battery thermal strategies and over-the-air updates. The U.S. Government Accountability Office (GAO) has reported that NHTSA is seeing a growing number of recalls that can be remedied through over-the-air software updates, which can improve recall completion, but this also means a vehicle’s service state can change after manufacture. A repairer needs software status, update history and calibration state, not unrestricted control over every feature.

But not everything is confined to the battery; ADAS and collision repair extend the issue beyond the battery. Battery EVs (BEVs) averaged 1.70 calibrations per repairable estimate in 2025, compared with 1.54 for ICE vehicles, and OEM parts accounted for 86% of BEV parts dollars versus 62% for ICE vehicles. Insurers, fleets, and independent repairers therefore need reliable procedures, parts pathways and access to calibration; without those inputs, repair access remains incomplete in collision work.

Where safeguards end and market control begins

Some OEM restrictions deserve sincere technical respect; not every action is motivated by business self-interest. NHTSA’s cybersecurity best practices support authentication and access control for diagnostic tools that can reprogram modules or affect safety-critical systems. Firmware flashing, immobilizer functions, battery commissioning, propulsion-controller write access, and some ADAS calibration operations should indeed require credentials, logs and appropriate training. The repair right should not become a right to defeat cybersecurity or return an unsafe vehicle to the road.

Other restrictions, though, deserve more scrutiny. Withholding read-only diagnostic data, battery health information, wiring diagrams or service procedures does not automatically improve safety. Blocking a qualified shop from completing a lawful parts-pairing or calibration step can turn a replacement part into an authorized-channel transaction. Limiting telematics-based diagnosis to OEM or dealer channels can shape the repair market before the owner even chooses a provider.

The issue is currently well illustrated by telematics. GAO found that automakers and most independent repair stakeholders it interviewed said telematics data was not currently needed for most repairs, because necessary data remained available through the physical port. The same report warned that OEM control of telematics could disadvantage independent shops through remote diagnostics and proactive repair marketing; the risk is that future repair access may migrate to an OEM-controlled channel.

Incentives across the repair economy

Consumers benefit from competition, but they also need safe outcomes. A lower repair invoice has little value if an incorrectly serviced battery or sensor creates a later hazard. Fleets need uptime and may accept credentialing if it lets in-house or contracted technicians diagnose vehicles quickly. They are less likely to accept a model that requires every software reset or battery assessment to go through a dealer.

OEMs have legitimate interests in safety, cybersecurity, recall integrity, warranty administration and brand reputation. They also benefit when the service network is broad enough to support EV adoption outside dense urban markets. At the same time, authorized channels can preserve parts sales, service relationships and vehicle data relationships, so access limits require scrutiny. Dealers invest in factory tooling and training, but dealer-only access can restrict competition. Independent shops, suppliers and aftermarket tool providers need standardized diagnostic access, fair subscription terms, service documentation and parts information to remain viable. Insurers need battery and calibration data to avoid unnecessary total losses and to accurately price repairs.

The 2023 industry Automotive Repair Data Sharing Commitment covers BEV, hybrid, plug-in hybrid, and fuel-cell vehicles and says telematics should not be used to circumvent repair-data access. It helps define a voluntary baseline, but it does not replace enforceable access rules. The federal REPAIR Act would address access to motor vehicle data, critical repair information and tools. Maine’s 2026 right-to-repair law requires standardized access to onboard diagnostic systems, fair and reasonable access to tools, parts, software, and components, and an owner-authorization platform for telematics-equipped vehicles by September 1, 2027.

A practical government role should not mandate unsafe openness but require owner-authorized parity access to repair data, service manuals, diagnostic functions, battery condition, lawful parts commissioning and calibration procedures. It should also require cybersecurity controls, including credentialing, audit logs, proximity limits on sensitive commands, privacy controls and penalties for misuse.

Comparable rights, different implementation

EV owners can have a right to repair comparable to ICE owners, but not by copying the old implementation. The legal principle should remain the same: ownership must include the practical ability to choose a competent repair provider in a competitive market. The technical implementation must change because EVs are high-voltage, software-defined and calibration-dependent machines.

Unrestricted access to every command, firmware image, and security function would create safety and cybersecurity risks that traditional mechanical repair rules never had to manage at the same scale, but OEM exclusivity presented as safety is also inadequate. High-voltage hazards and cybersecurity risks justify the use of credentials, logging and training, but they do not justify withholding read-only diagnostics, battery condition, service documentation, lawful parts commissioning or owner-authorized repair data.

Therefore, the correct EV repair right is secure parity access. Owners should not gain casual authority to rewrite propulsion software. They should be able to have a battery fault diagnosed, a replacement part commissioned, an ADAS sensor calibrated and a software-dependent repair completed by a qualified shop that is not forced into dealer status.

Under that standard, EV owners will not have the same repair experience as ICE owners. They can have the same repair autonomy where it matters: real choice, safe repair, competitive service and control over the vehicle's useful life.
