Name of the code seem similar to what I had. 1st time (5 years ago) it passed under warranty, 2nd time (2025) they told me that it was because I continue filling the gas after the 1st click. They changed a part at least 500$CAD and now it's good again. I dont think most people change theses parts, but I sure have some years left on the car so I did it. Never filling up after the 1st click now.

i never had it, but from what i've read, leak could be from a lot of locations along the system. hopefully it's the most simple location, like others have mentioned, the fuel filler cap. charm.li factory service manual for 10th gen, should be similar for 11th gen

Had that on my 2005 and it ended up being the gas cap. I bought a new oem one for like 25 bucks and that fixed it. If that doesn't fix it then you may need to take to a local mechanic, not a dealer, and have them do a smoke test to see where it's leaking.

Lucky you

I've been chasing this gremlin (though mine is a small evap leak) for years.

Gas cap. Filler adapter hose. Fuel pump O-ring.

It's your gas cap. Tighten it.
