This may have been discussed on here before but I am a neebie and couldn't find it. I bought a 06 Nismo CC with 87,XXX miles and on the way home the SES light came on. Took it into the dealer and they say both of the primary cats need to be replaced ($2,350.00). O!U!C!H! I have owed over 30 vehicles and have never had to replace a cat. How could a company design a vehicle this way? Anyway, took it to my regular mechanic and they diagnosed the same problem. Any others on here have to do this? Hate to replace them and that not be the real problem. Any help/advise available?:sickly:

All too common. Weird that both went at the same time though. Did the light go on as you were driving it home from the purchase of the truck. If yes, most states have a law that requires the vehicle to be able to pass emissions testing at the time of purchase. If it does not, the seller either pays for repairs, or the buyer can return the vehicle for the amount paid.
I'm at 30k and my bank 1 primary cat is TOASTTTTTTTTTTT.... along with the after cat 02 sensor by now too... bullshi* if ya ask me! dumb. .. sucker that you're barely out of the 8 year 80k mile emissions warranty. I've been driving with p0420 for... uhm, probably a lot longer than I should. hmm.
I bought the truck in Texas and drove it home to Tennessee. Used dealer says light was not on when it left their possession but did make offer to pay part of the costs. If Nissan warrants the Altima CVT transmission to 120K why won't they warrant the cats to at least 100K. What can be done in the future to keep them from going bad again?
After pricing through the dealer, I called a couple of auto repair shops to price the job. Both shops told me they do not make a aftermarket cat for this vehicle. I went online and found replacement cats through partsbin.com for $262.00 compared to the $700+ through the dealer. Anyone have experience with aftermarket cats for this application.

What type of fuel do you use? The owners manual recommends 91 or higher for the VQ powered trucks. I would imagine if the PO used 87 or lower to save money this could have caused the motor to retard too much timing clogging the converters early in their lifespan.

Glad to know I'm not the only one. I bought my 2005 brand new and take good care of it, though I usually run regular in it. At 85k both of my cats failed, and it cost me 3k all told to have them replaced.
The part that worries me is that the dealer techs have no clue why they failed. They could not find anything that would explain it.

I would say do Hi Flo cats. And soon. Mine failed on me back in january, didn't treat the ses light with enough respect when it came on. Truck eventually lost all power. Had Hi Flo cats installed inplace of failed primaries, but, was unfortunately to late. Damage had been done. Cat(s) got plugged up, broke up, and pieces got sucked back into motor. My truck is currently still dead, as I have to replace the motor (soon).
Whatever you do, do it soon, cause it can get pricey. And so far, $2300 for the cats is reasonable compared to the cost of a motor replacement if it calfs on you. And you'd still need to fix the cats too. But go aftermarket, you'll save atleast 1k bucks.
Best of luck.

Honestly the manual says to use 91, that's what I would run. I bet this is the cause for pre-mature failure of the cats.
