My 2013 Edge with the 3.5L and 119k miles has the following codes: P0420 - Catalyst Efficiency Less Than Threshold Bank #1 P0430 - Catalyst Efficiency Less Than Threshold Bank #2 P0325- Knock/Combustion Vibration Sensor A Circuit. Ive been doing some reading on the first 2 codes and it seems to be either O2 sensors or the Cats. Some people have said theres some flaws with this particular exhaust system and these codes are VERY common. I dont have a lot of money so replacing the Cats would be financially impossible for me currently. Do you think i could replace the 2 O2 sensors and be okay? Second, the Knock Sensor code im assuming is just the sensor is bad. Could this code possibly cause the 0420 and 0430 codes or are they unrelated? Just trying to get a better understanding and some helpful advice on how to approach this. Any advice would be welcome! Thanks in advance!

So my 2013 Ford Edge has this issue that just started today. My Climate Control just turns on and off by itself and the buttons below the screen go dark. Sometimes it turns on and off rapidly like on and off every second. Heres a video i got of it happening. If anyone can point me in the right direction id appreciate it. Its currently 3° in Michigan and having no heat is miserable. https://youtu.be/4dzo6jkvKfI?si=sjeY9WL4eor4XgeC UPDATES: If i remote remotethe car, everything works fine. As soon as i get in and hit the brake and the Start button, everything dies. i put a new battery in it and it kept doing it so battery isnt the issue.
