Cat and ECU are covered under the 8 years/80,000 miles federal emissions warranty.
The emissions warranty on the 2003 Corolla is for 70000 miles. I have recently had the check engine light come on and had the dealership analyze the issue. They pointed to the catalytic converter. The check engine light came on shortly after the car reached 75000 miles. Bad new is the dealership quoted repairs at over $1200! Needless to say, I was not happy with the diagnosis nor the price. I expect better from Toyota products.
65000 - 75000 miles
