It's going to be close, but you may still qualify for a catalytic converter under the Extended Federal Emission Warranty. Hi, DBL, my name is Ed. Welcome to JustAnswer!.

I'd expect the dealer to have checked this, but somethings stuff happens. If your Pacifica went into service less than eight years ago, the cat converter will be covered 100% unless some exclusion in your warranty coverage occurred. I could even check this for you if you don't mind sending me the last 8 digits of the VIN.

As for future failures... I hate to get put in this spot! Occasional evaporative system leak codes, tire pressure sensors and broken motor mounts come to mind, but nothing major happens on a consistent basis. Front end parts (tie rod ends, steering rack) may loosen and leak a bit and struts will begin weakening at this point, giving you a bit "bouncier" ride than new.

If we don't luck out with the free replacement catalyst, aftermarket sources have improved over the last few years in my opinion. Maremount offers a pretty affordable 3-way cat that would have to be installed by a muffler shop, but will undercut the factory price by several hundred dollars and is warranted for at least two years. My personal experience with the Maremount line has been very favorable when I need to send a vehicle out for repair and I even went that route with my own vehicle.

It looks like I may have missed you for chat, so I'll step out for now and roll this thread over to conventional Question and Answer, which looks and works a lot like regular email. I'll get a notification when you write next and we'll continue from there.

Talk in a bit,
