I'll give it a shot, thank you.

No other codes, not running bad, not doing anything other then the P0420 code. The O2 sensors are bosch. I can clear it and sometimes it will come right back on or it will be a few days. It always does it under 2,000 RPMs and about 50 MPH.

So I got the P0420 code. I have a 2017 2.4L and its hard for me to believe the cat is bad. I've replaced both O2 sensors, new plugs, filter, cleaned the throttle body and almost every sensor in the car. Any ideas before I spend the money for a new cat?
