Honda’s emissions warranty protects new vehicles against defects in emission-control systems that could affect air quality. In the United States, the standard protections typically include a federal emission warranty of 3 years or 36,000 miles for most emission-control components, with longer protection—often up to 8 years or 80,000 miles—for the catalytic converter and other major parts. California and other CARB states have their own rules that can affect what is covered and for how long. Always check the warranty booklet that comes with your car for model-year and state-specific terms.
How the Honda emissions warranty works
The warranty is designed to guarantee that Honda’s emission-control systems function properly and meet clean-air standards. It is governed by federal law, and where applicable, state emission requirements. Coverage generally begins on the vehicle’s in-service date and requires maintenance as described in the owner’s manual to remain valid.
What is covered and for how long
The following items summarize typical coverage you’ll see in Honda’s emissions warranties. Exact terms vary by model year and by state, so verify the terms in your warranty booklet.
- Federal Emissions Warranty: Most emission-control components are covered for 3 years or 36,000 miles; the catalytic converter and certain major emission-control parts receive longer protection, commonly up to 8 years or 80,000 miles.
- California Emissions Warranty (CARB states): Vehicles sold in California and other CARB states follow California-specific rules, which generally align with federal terms but can include state-specific protections. Check the Honda California Emissions Warranty booklet for precise durations by part and year.
- Maintenance requirements and eligibility: Coverage depends on proper maintenance per the owner's manual, and does not cover damage from accidents, misuse, or modifications.
These terms illustrate Honda’s commitment to ensuring emission-control systems work properly and to help owners avoid costly repairs due to manufacturing defects.
Summary
Honda’s emissions warranty provides protection against defects in emission-control systems. The typical federal coverage includes a 3-year/36,000-mile basic warranty, with an 8-year/80,000-mile extension for the catalytic converter and major components. California and other CARB-state customers may have additional protections. Because terms vary by model year and location, always consult the warranty booklet or Honda’s official materials for your exact terms.
