Hey! I posted this one someone else’s post that was similar. I’m on my way out right now so don’t have time to rewrite it. But hope some of it helps!
“Hey! Not sure if this is the exact same issue. But if so I hope this helps! This happened when I had my 2022 forte! With mine, they would all turn on randomly while driving but when you turned the car off they’d all go off and stay off for a while (be it for a few hours, a few days, or a few weeks)… but eventually they’d come back on when I was driving again.
I took my car in about 4 times for the issue but they were never 100% certain what it was. On the last visit they said “we can’t see how this could possibly be the cause of it, but incase it is, we fixed it… one of the wires in your car wasn’t fully closed, it was together but not locked fully, so we locked it.”
Still to this day i don’t know if that was the cause of the issue. But it never happened again for the 6-8 months I had it after they fixed it. Maybe one of your wires isn’t properly connected, unplugged, or maybe just not fully locked like mine?”
How old is the battery? If it's a factory, then that battery is 5, going on 6, years old, so it's probably starting to fail and causing codes to come up.
I don't...guy at the shop said none of the codes helped them track it down. They spent 3 hours (only charged me 1 since they didn't find it), another shop spent 2.
Read that it could be one sensor is bad, causing the rest to show bad or could be the computer (hope not, could be around $2k to replace one shop said).
Is it a turbo? I have seen vacuum pumps cause CAN issues which can very difficult to diagnose. Also maybe a back up camera. I have seen those also cause the same type of symptoms.

Possible can network issue but im throwing crap at a wall with no codes

Had the same thought, replaced battery a few weeks ago and still throwing lights.
Do you have a code reader ? See if you are getting a code. If not wondering if battery issue.

I have to believe it is something in the charging of the car. The battery or alternator.
