Why this grade
Most closed of the group. A federal antitrust class action alleging Tesla monopolizes its repair and parts markets survived a motion to dismiss in June 2024 (Judge found 'direct and indirect evidence of monopoly power' in Tesla repair/parts markets) before plaintiffs voluntarily dismissed it in June 2025 — dismissal was procedural, not a vindication. Tesla designs vehicles so deep diagnostics rely on remote/OTA tools it controls, restricts OEM parts, and frequent on-the-fly design changes make repair parts scarce; insurers routinely total lightly damaged Teslas because battery-area impacts and parts scarcity push repair cost above value (KBB documented 120+ low-mileage Model Ys totaled). Tesla permanently disables Supercharging/3rd-party fast-charging on salvage-titled cars (Unsupported Vehicle Policy), with a $1,200-2,000 HV inspection as the only official path to restore it — a clear software lock. Tesla does publish a public service-info/parts catalog at service.tesla.com (partly forced by MA/MN law), lifting schematics somewhat, and signed onto the 2023 ASA/Auto Innovators R2R pact, but advocates remain skeptical it changes the closed model.
