Is There a Warranty on Catalytic Converters?

Each vehicle manufacturer provides its warranty information in either the owner's manual or warranty guide included in any new vehicle purchase. The government also regulates a federally mandated warranty for emission control parts, covering the catalytic converter on vehicles made in 1995 or later, for eight years or 80,000 miles.

The Clean Air Act requires manufacturers of light-duty vehicles to provide a performance warranty and a design and defect warranty. These warranties are provided by the vehicle manufacturer and also apply to used vehicles, beginning from the date of sale to the original owner. All procedures for making a warranty claim as identified by the manufacturer are listed in the owner’s manual or warranty booklet of the vehicle and should be followed as instructed.
