catalytic converter failure on 2005 Honda Civic Hybrid

After the check engine came on at about 105,000 miles, service check informed me that catalytic converter needed to be replaced and that it would cost $1250. If I continue to drive the care without the repair can it cause damage to any other components or affect the car's performance? I have seen elsewhere that the engine light could be caused simply by a computer bug.

The 'computer bug' info is nonsense. Catalytic converters fail a lot on Hybrids, because the engine has to run so very lean and this works the CAT really hard. I would ask Honda for some support. they should step and help you. This is a common failure. Good Luck! by the way, the code is 'P0420 Catalytic Converter operation below efficiency threshold'. This is a well documented and a 15 year old code. it is far from being a computer bug' I see this problem every day at work because I do Emissions Diagnostic work in N Calif. If you continue to drive the car, you will be running at a much lower fuel economy level and be polluting the air. Is this not the reason for a Hybrid in the first place, to be a Greener Driver?

The computer bug code is not nonsense if the code is p2000- Honda issued a service bulletin in 2007 about it. Software update fixes it if this is all it is.
