Last Friday when I was driving to work, I got the check engine light on my 2019 JLR 2.0 Turbo. Its only 5 months old with a little under 8k miles on it, all stock.

I read the code using one of those ODB2 readers and found it it was a P0455 (Evaporative Emission System Tank Leak Detected - Large Leak). After a quick google check, I made sure the gas cap was tight. The light was still on for the rest of the day so I scheduled an appointment with the dealer just to make sure it wasn't anything serious.

Two days later on Sunday, the light goes away and everything seems to be normal. I cancelled my appointment with the dealer as I figured it was probably the gas cap or just an error.

Should I be concerned about anything else? Should I take it in to the dealer anyways? With the light being gone, are they going to be able to check anything?

I also got an email from Jeep VHR:

Just wait and see if it asks up again.... Might be wasting your time at a dealership if the CEL isn't on... Might give you the "cant replicate the problem" spiel

Hi Alex - Thanks for reaching out. I will definitely take it in to the dealer if the light comes back again and will send you a message then.

Hello, did the light come back on at all? Same thing is going on with mine. The last two times i have put gas, my light came on and it’s the same emissions code.

Mine hasn't come back yet. Although now I am extra careful to make sure the gas cap is on tight (4 clicks).

A "large leak" usually indicates that your gas cap wasn't making a tight seal. May have just needed that extra click.
