2400 miles and throwing a p0420 code..seriously?

greeknasty, have you taken a look at this thread? Call the dealer and have them check it out. Could be caused by overfilling the gas tank according the thread I linked. Good luck.

Could a loose gas cap throw the same codes?

You can try removing the gas cap and replacing it. But it may take driving a few minutes for the light to go off. The important thing is you're under warranty. The dealer should take care of it.

This code indicates catalytic converter inefficiency, meaning it's operating at less than 99% efficiency or something is making it operate inefficiently. Take it to the dealer and have them deal with it. It's under warranty, no reason for you to worry.

By the way, the last time it happened to me, I fixed it by cleaning the gas filler cap seal with some light oil when I noticed there was some dirt on it. Just some oil on paper towel and wiped the seal.

They can but they won't, knowing if there is a real problem the code would just come back.

got back..they cleared it and drove it(waste of time considering this code takes a while to come back) and didnt see nothing that popped out at them and told me to keep an eye out..
hopefully it was somethin stupid and not a issue in the long run.
thanks for your replies

ok so the code came back....figures!
heres what gets me..the code is a permanent DTC. if you dont know thats the new stuff 09 cars and later have that once the code pops up it doesnt go away regardless of clearing with tool and the only way for it to go away is fix the problem and the computer sees its fixed or do the universal trip drive pattern.
i checked the voltage from the o2 sensors and all look normal..also there were cat temps showin 500+ and then another number was 200-300 below not sure what those were.
can anyone enlighten me on this?
