Re: Cat Recall
As long as you don't take it to the dealership, it won't get done.
It's not a safety issue, for the most part. If it goes into limp mode (limited to third gear), it could be, but most failure modes just give a "no restart" warning, meaning you can keep driving normally, but it can't be started again if you shut it off.
If it were me, I'd drag it out as long as possible to extend the overall life, much as you suggest. There are usually telltale warning signs (low fuel mileage, codes related to DEF quality) long before the dreaded "no restart" or limp mode.
