This is true. US EPA federal warranty guidelines indicate a vehicle 8 years or newer should have its catalytic converter repaired free of charge to the owner. There are strict policies on this however; like what condition was the vehicle maintained in during the first 8 years. In this specific case you will need to dicuss this matter with the Toyota dealership. There are two concerns... one being the production month and year of your Toyota Camry (vehicles are often sold in the previous year of the production model year). Check the primary VIN label on door (or door post) for the actual month and year of production. Second, was your Toyota Camry properly maintained during the last 8 years, and were there neglected repairs which contributed to the failure of the catalytic converter. The federal emissions warranty is strictly in place to repair (replace) manufacture defective emission components.
