CHEVROLET HHR DENT PROBLEM

2007 Chevrolet HHR • 13,000 miles

I got into an accident a week ago and my rear passenger door has extensive damage that is estimated at $2500 to repair. Now, after a few days, my check engine light came on. Took it to Auto Zone and they say the code that came up is P0420, which said catalyst system low efficiency. Could this be due to the impact of the accident. I've never had my check engine light come on since I have owned the vehicle which is about 4 years. I called my insurance company and they say now that my car is non driveable. I have to take my car in on Monday to see what is going on now.

No 420 is a cat inefficiency code. The precious metals inside are not doing there job anymore. It needs to be replaced. Nothing to do with the accident

not driveable? Why?
