This is just a shot in the dark, but testing the main 12V battery may be worthwhile. From what I know a lot of the electronics run off the 12V battery, so a bad battery could be causing the electronics to not function correctly.

Don't trust their testing and judgement, get a voltmeter and make your own measurements. An old, weak or worn out 12V battery can cause a multitude of random faults and unrelated errors such as you are having.They tested the 12v battery and said it was good.
For what it’s worth, LeafSpy says the 12V batter is good.Don't trust their testing and judgement, get a voltmeter and make your own measurements. An old, weak or worn out 12V battery can cause a multitude of random faults and unrelated errors such as you are having.
i had a dealer give me the same "it's good" response and claimed that the main HV battery was "bad". They were wrong in a big way.
Only a capacity test or specific gravity test would give good confidence about the 12V battery.
Since you have a 2022 model car, chances are that the 12V battery was made in 2021, so it is at least 3 years old. If it has ever been allowed to sit for an extended time with a less-than-full charge, then it has likely suffered sulfation damage that will reduce the capacity. It may appear to be good under their test, but fail or lay down under the load profile of the car.
Yes, LeafSpy reports several weak cells.Take your Leaf to the auto parts store. They will test your 12V battery right in the car. They attach a set of cable to the battery and then start the testing machine. The machine measures the battery voltage before, during and after the load test. If the battery sags too much then it is worn out. In an ICEV that would be revealed with an engine starter that was slow and dragging. In an EV it reveals itself as gremlins. Eliminate that possibility.
Then move on to the traction battery. Does Leaf Spy show any low cells or bad health markers? Is your charger bad? Have you charged somewhere else to see if the commercial charger brings your battery up? I'm guessing that one or more cells in your traction battery have gone bad.
You will likely need to find another dealer.
Also, one of the battery temperature readings is always much higher than the others.Yes, LeafSpy reports several weak cells.
