? There is absolutely no warranty on work or damage resulting from blocked cats after recall. It’s still 100% at owners risk. Plenty of recalled cars with remaps have suffered as do e52 so if you think Nissan has solved the twin stage cat blocked hardware with a software update then great BUT you will be proved wrong eventually... or pass the risk on to a subsequent owner.
@Reuben says the dealer provides a three year warranty. I'm guessing he got it from the same place as @George322 who mentioned his dealer provided a full 3 year warranty in another thread.
Don't be telling me off now - I've had mine done
