What is the standard emissions warranty for all U.S vehicles?

The standard emissions warranty for all U.S vehicles covers emissions-related parts for a duration of two years or 24,000 miles. This warranty is established under federal law as part of the Clean Air Act, which mandates that manufacturers must ensure that their vehicles comply with emissions standards and that they provide a warranty to consumers for the associated parts. This warranty is important because it protects vehicle owners from defects in materials or workmanship that could lead to increased emissions, which can negatively impact both the environment and the vehicle's performance.

Vehicles are also subjected to more extended warranties for certain critical components related to emissions control, but the two-year and 24,000-mile period is the baseline requirement for manufacturers. This framework encourages manufacturers to be accountable for their products while aiding consumers in maintaining compliance with emissions regulations. Other durations listed in the options represent different types of warranties or specific vehicle components, but the correct standard emissions warranty is indeed for two years and 24,000 miles.
