2005 STS-V8 Catalytic Converter Problems

[MAC]

Anyone with a 2005 STS with a V8 engine should be aware, if you haven't already received notice from GM, that the catalytic converters are prematurely breaking down and that GM will replace them free of charge. If the check engine light is on take it to a Cadillac dealership for diagnosis. If it involves one or both catalytic converters then schedule an appointment for replacement. If the dealership determines the problem is one or both catalytic converters, GM will replace them free of charge. This warranty has been extended by GM until 12 years or 200,000 miles, whichever comes first.

I had both catalytic converters replaced. The job took all morning into the afternoon.

Do you know if this applys to the 2006 STS V8. We are having the same problems and have been told by a GM dealer that both of our converters are bad and need to be replaced!

To my knowledge, GM has not issued an extended warranty for the 2006 model year. If they did, I would think you would have been advised by the GM service department.
