Re: [Help] 2003 Impala P0420 Code

You might check with your Chevy dealership. I know I got my cat replaced free because of a recall and they extended the warranty out on it for (I think) 10 years. I have a 2002 Impala.

I call the dealership last year when the OEM cat failed and they told me that it was not covered under warranty. It was covered up to 100,000 and at the time I had 102,000 on the car.

I would call Chevy Customer Care directly to confirm it. My 2001 Pontiac Grand Prix had a clogged cat. converter 2 year ago; a few months later, GM sent me a letter to acknowledge some defect with their cat converters on 2001 (and up) cars and extended the warranty to 10yr/120,000 miles.

Being yours is 2003 car and Impala & Grand Prix are similar cars, GM could have used the same cat. converter.

Before I purchased the new cat I talk to the service department again. They looked up my VIN and it only covers 2000-2002 Impalas and Monte Carlo's up to a 120,000 and of course my car is a 2003. I might call GM directly and see if they will cover the cost(but i doubt it). My sister who has a 2002 Monte Carlo had her cat replace at 90,000 under the recall.
