The most common cause of something like this is raw fuel entering the converter. Have you experienced a misfire or poor fuel mileage? Also, an exhaust leak, faulty oxygen sensor, or wiring issue can cause the issue.
Are there any other codes that are present? Any exhaust leaks heard?
I also want you to know that the catalytic converter on this vehicle is covered by the manufacturer for 8 years or 80,000 miles. See pic 1. Pic 1 comes from section 10 page 38 of the owner's manual and warranty information handbook that should have come with the car.
Let me know if this helps or if you have other questions.
Take care and God Bless,
