Instrument Cluster flashes and goes dark

[jayflow2010]

Hello, I'm new to the group, I have a 2020 Jeep Wrangler Sahara 2.0 . A few days ago the screen started to flicker. First it went dark and then it started to flicker. The strange thing is that it only does this when I leave work in the afternoon. In the morning it turns on as soon as I open the door and it works correctly until I arrive. I checked the fuse, pressed it, measured the battery and it is at 12.6v. It is working correctly. I would like to see if anyone has had this experience and how to fix it. The vehicle is out of warranty and workshops are very expensive. When perhaps the solution is something simple like a fuse, I checked the fuse map but I did not find the exact fuse for the instrument cluster.

I added a video of what he is doing

There is a recall for the Instrument Cluster, check out the following thread:

Edit: Sorry, that’s for the 3” display. But still worth reporting to the dealer, as it could be related.

On my 2021 JL eTorque that exact light show meant a bad main battery (I do not have the auxiliary). Replaced with H7 Costco and all resolved/fixed. Make sure your battery is good indeed. If in the morning is OK, perhaps your car is in a garage and it might be warm and voltage is right on, but in the afternoon (assuming parked outside and in colder place), the voltage could drop slightly just so the computer gets messed up and scrambles your cluster lights?
Not sure if your Jeep is with 2 batteries, the AUX might be bad, too, while the main one is OK. If you are on the battery replacement, good idea is to change them both in the same time (if your Jeep has 2).
Good luck...

I think this is often a symptom of a canbus failure.
