Dealer is BSing me P2A00 & P0420 codes
I have an 07 G35 Sedan with 40k miles and recently had a check engine light show the following codes.
The dealer told me the catalytic converters were cracked and need to be replaced for $3k due to a recent incident where I rear ended someone. Keep in mind the damage from the accident was a scuff on the front bumper and a quarter size dent on the top of the hood. No air bags went off and no other damage to the car.
I think that the pre-cats are breaking up (seems like this is somewhat common on the 3.5L motor, but I can't find much documentation or a TSB)
Any help, links, suggestions, from someone who has gone through this would be appreciated

Have the dealer put that crap in writing, then take that to your insurance company and have them pay for the repair (hopefully you already paid yor deductible from the first accident). That way, you'll have zero out of pocket cost.
Having said that, unless you really smacked the car in front of you and caused the motor to shift, it's highly unlikely your accident caused the cats to go bad

+1 on that... I'm just waiting for mine to show signs of needing replacement, and then it's game on

man i have had these codes for a several thousand miles now. IT WASNT MY CATS. they were mint condition when i pulled them off. I replaced them with GTM test pipes and i still have the 0420 code. I believe that one or more o2 sensors are bad.
But i have followed this on my350z and the dealerships cant diagnose their problems either. its a bunch of BS that has had me almost selling the car twice now.

Whatever you do dont make another insurance claim. Especially for 3k.
They will def keep track of that stuff. Rates will rise even more than you have now.
I would go the aftermarket route if you believe the dealer. I would also check the O2 sensors like some one said before.
$3k is a joke. They wont use more than 3 wrenches to get your cats off and it should take them like 1.5 hours at the most.... Thats called mark up.
