My car has 100,000. Is catalytic converters cover by federal emission defect

Hello, "Federal" emissions warranty typically covers components to 7 years / 70,000 miles. You'd be best off consulting your local Hyundai dealership to inquire about specific coverages in your area with your VIN (vehicle identification number) and mileage. Also - why do your catalytic converters need to be replaced? They almost never fail on their own, and most often fail as the result of other component concerns.
