Freedom to Fix

Freedom to Fix Guidance

What is EPA doing?

In response to President Trump’s directive in Presidential Memorandum, “Lowering the Cost of Living by Promoting the Freedom to Fix”, EPA has issued guidance to manufacturers reaffirming that the Clean Air Act supports Americans’ Freedom to Fix their own vehicles and equipment, regardless of vehicle or equipment type.

Why This Matters?

These actions directly address concerns raised by independent repair shops, farmers, truckers, and other equipment operators who face unnecessary delays, costs, and safety risks due to restrictive repair practices. EPA’s clarification supports economic productivity, reduces downtime, and ensures emissions standards are met in real-world conditions without imposing unnecessary burdens.

Nonroad Equipment

In February 2026, EPA issued guidance affirming the Right to Repair for farmers and owners of nonroad diesel equipment, including agricultural machinery. Read the press release.

This action clarifies that temporary disablement of emissions controls for the purpose of repair is allowed under existing law and reinforces manufacturers’ obligations to provide the tools, software, and diagnostic information needed to fix modern vehicles.

Light-Duty Vehicles, Light-Duty Trucks, and Heavy-Duty Commercial Trucks

The Clean Air Act also requires manufacturers to provide “any and all information” needed to diagnose and repair emission control systems Light-Duty Vehicles, Light-Duty Trucks, and Heavy-Duty Commercial Trucks. These regulatory provisions ensure that owners and independent repair shops can legally and effectively repair modern vehicles and engines.

Under EPA’s regulations, manufacturers must provide:

  • Full emissions-related service information
  • Training materials
  • OBD data and enhanced diagnostics
  • Passthrough reprogramming information
  • Manufacturer-specific tools for purchase

In July of 2026, EPA issued  guidance (pdf) (211.86 KB, July 1, 2026)  affirming the Freedom to Fix for aftermarket repair shops. Read the press release.
