I had a P0455 before, and it was the evap purge valve. But that P0420 code is worrying because it could mean the catalytic converter is going bad.

Yeah, I’m pretty sure it’s the catalytic converter.

What’s the year and mileage on your car?

It’s a 2017 with 115,000 miles.

It’s sounding like it’s the converter.

Someone told me it might be because it was -45 yesterday, and my car wouldn’t start because of the cold. Now it’s working harder, but I’m still going to get it checked. How long can I drive it like this before it becomes a bigger problem?

Is it the 1.6L engine?

I believe it is, yes.
Could be the filler neck or a clogged canister, maybe the purge valve, or even the catalytic converter.
I’m dealing with the same issue. I’ve replaced the purge valve, solenoid, and hose, and now I’m looking at dropping the tank to replace the canister and fuel neck. If that doesn’t work, the cat is next.
But now my engine mount bushings are shot, and it’s time for another timing belt, so I might just start riding my bike instead.
@SoulSeeker
How do you know if your engine mounts are bad? Asking because sometimes when I accelerate in the rain, my front wheels spin out and do this hopping thing, kind of like peeling out in reverse with a rear-wheel-drive car.
@Benard
Mine makes a rumbling noise at idle, and you can actually feel the rubber in the bushings breaking down.
What you’re describing sounds more like a traction control issue. Is your traction control on when that happens?
An evap code is related to emissions, not the engine itself. It usually doesn’t cost much to fix and can be ignored for a bit if money’s tight right now.
P0420 is just the manifold catalytic converter. I replaced mine a few weeks ago on my 2017 1.6L. It was $2,166 at Premier Kia, but I did it myself. For the P0455, try replacing the gas cap first. I had that code pop up, and it disappeared after tightening the gas cap when I drove it off the dealer lot.
@Aydin
Well, I guess I’m screwed then
No, it’s not a huge deal, but your car will use more gas than normal. Both of my Honda Elements had the same code, and it turned out to be the catalytic converter each time.
I had the same problem with a 2017. Instead of jumping to conclusions, I cleared the code a couple of times and made small fixes. Turned out the issue was the fuel tank pressure sensor. I replaced it myself after removing the backseat to access it, and the sensor cost me about 20-30 bucks.
In my case, the light came on and off because the sensor connection was a bit dirty or loose. Hope this helps!
@WilliamMia
I’ve got another pic saying it’s the catalytic converter. That’s the one stressing me out the most.
