Your Catalytic Converter is pretty much self sufficient, and is passive in regards to your car.
To make it last a long time, DO NOT introduce anything but Unleaded fuel. Don't add acetone or any other "miracle" additive, as they are a profound waste of money.
Keep your car well tuned, and when the "Check Engine" light comes on, DON'T ignore it. It will only come on when there is an emissions problem. If you begin to burn oil, or if the engine begins to "use" coolant that is not leaking, repair it. All of the above can have significant impact on the life and functionality of the Catalytic Converter.
As for the gas fumes, this could be an EVAP system failure. Ask the garage to investigate for you.
Good Luck and Merry Christmas

It sounds like your engine is messed up. You need to fix your engine before you can even diagnose the catalytic converter (cat).
Incompetent mechanics always blame the 'cat (or the computer). The 'cat is just a passive smog filter. It has no moving parts and cannot break unless something is seriously wrong with the engine or emission controls. Fixing that will probably be cheaper than a cat. If you do that, the cat may recover.
I have a hunch that your "Check engine" aka "Service engine soon" light has been on for a long time, and you have been ignoring it.
Also the very short distances mean your engine never really warms up... a bunch of stuff doesn't happen that's supposed to. Cat doesn't get warmed up (hello!) canister purge doesn't happen (gas smell!) etc. That might be the source of your problem. You need to start driving that car real distances regularly - 15 miles (several miles over 45 mph) twice a week. That alone might clear the problem.
If not, take it to a real mechanic who understands electronic engine controls, and knows to fix other things before the cat. Have him fix it "by the book" so the car runs sweet, and doesn't blow PCM error codes (for now, ignore cat related codes.) Drive the car long distances, and make sure it stays fixed! The cat should run great now. And the cat is likely to fix itself.
Next look at the pair of oxygen sensors which monitor the cat's health. In the old days, you replaced them every 60,000 miles, so it wouldn't surprise me if one was bad. Replace both as a matched pair. Finally, if that doesn't do it... then the cat really is bad :(

All the above posters are right. The converter is under federal warranty for 10 years. Dealership MUST replace, if it actually needs it. Now, what caused the converter to go bad is another story. Sounds like you've got a SERIOUS fuel system issue. Take it to the dealer.

get another price for replacing the catalytic converter ( that part is actually part of the muffler system and it has to get hot to work properly-----take a drive on the weekend----- loosing oil and high gas consumption and the "fumes" are all related to the clogged-up catlytic converter---- go to the Nissan dealer and talk to the service writer - he is there to help you and write the questions down before you leave home so you can get needed answers in one trip..
