I love how the dash turns into a Christmas tree

[BAULSAUL]

2023 jeep gladiator, Rubicon I purchased about five weeks ago. When I took delivery, and left the dealership, immediately the warning lights popped up and didn’t stop. Check engine light, swaybar, traction control, ABS, Lord knows what else. I lost track because it all happens at once. It does not happen one after the other 10 minutes apart. It happens in a matter of 10 seconds. Dealership tried to tell me it had something to do with filling the gas tank when the vehicle is running but I’m sure it has nothing to do with that and they just cleared the codes. fast forward to now. I converted all the halogen lights to LED and they all look fantastic. I have done no other modifications as of yet. I am sitting at about 1200 miles.

Today the same exact thing happened while I was driving down the street. Probably about 40 miles an hour. Everything is fine and there was no noises and everything was good except for the Christmas tree lights on my dashboard. After one or two minutes they went away. Then they came back five minutes later. I have my j scan, so I was able to clear all the codes. Hopefully it’s something stupid but I wanted to know if anybody has come across this issue before. I will share a picture of what my dash look like and the codes as well. Like I said, I cleared all the codes and they did not come back. But who knows. Maybe tomorrow they will. Battery voltage is good. All the fuses look good. Thank you in advance. Please let me know what you think. Based off the codes you see. I’m sure some of them are generic. using my Bluetooth so I apologize if there’s any spelling errors.

Have you checked to make sure all your fuses are fully seated? Many trucks have come from the factory with loose fuses.

Naw, this is a CANbus communication situation.

Jeeps are known for this type of issue.
The star connector between glove box and firewall - reseat those connections.
Similar happened to mine last year and after removing the glove box and getting to that connector setup and resetting things, the errors went away.
The codes themselves state what the issue is.
That's where I'd start - that connector array back of the glove box.

Even my dealer knew what the codes meant I was getting - CANbus.

You filled her up with the engine running again, didn't you?

Check your main Wire Harness to the ECU. I had a 2018 JL that did that. Dealer had to replace the whole Wiring Harness due to corrosion.

I had this happen intermittently with a cheaper obd2 Bluetooth dongle ... removed that and all was well

Thankfully with these, and this generation, CANbus errors like that are "almost always" that star connector array back of the glove box. There's a lot of posts here and in the Wrangler areas that talk of it. I had it on my 2022, and many others have had to reach back there and reseat things (a bit of dielectric grease doesn't seem to hurt any)
And it's something a decent DIYer can do.

You'll find other threads even in these JT forums about that issue and I think some of the early ones - likely by @Hootbro, link back to the Wrangler forums about these things.
He knows this stuff.
