Brand new rubicon with 300 miles on it and got a check engine light on. Hopefully it’s something simple

2023 Diesel. I got TONS of codes the first year, even limp mode once. I restarted and cleared them with the Tazer. The dealer fever found anything.

it’s been over a year with no codes at all 😳

What does it all mean? 42 maybe 🤔

Let us know if the gas cap fixes it permanently. We got a 2024 Willys and the same thing happened…but roughly 409 miles and again after 700 miles (after I had a shop reset the first light).

I’m about to buy a new gas cap to see if that fixes it.

Unfortunately, I don’t have the luxury of a US dealer near me so I can’t just take ours in. Having to live through others, stateside who can lmao

If it’s not the gas cap, idk what the heck it could be without taking it in which would be a PITA for me ☠

*Update, I ordered a new gas cap off eBay from an Arizona dealer (saved on shipping and such) and two days later the light turned itself off for now :facepalm:

We'll see how long it stays off for. If it comes back, I'll replace the cap and clear the code by disconnecting the battery...then see how long it stays off for.
