Smells like a battery that is become unbalanced. Refusing to charge from a low range is an indicator I had a '13 P85. I think it was more common in '12 and '13. We don't hear of it in more recent years. Even with 110K miles I think the battery is still covered under warranty.
You will get a reconditioned battery. It will be great. You can look forward to 90% charge to be about 2-3 miles better than yours was when brand new. Don't consider this a bad thing. You are going to be very pleased with the outcome.

Memory saturation? Never heard of that. If you can get more detailed info from SC about this, please come back and tell us.

U will get a 90. Dont make 85 anymore. Re badged.
Man at SC told me we could pay extra and get a 100 battery . He said they were same pack, it was all done with sw reprogramming .
You should ask. IN WRITING to Tesla via your account.

The fact they don’t make them any more isn’t really relevant. They don’t make the 90 either. I’m sure they have a constant supply coming in from warranty replacements that are repaired and reconditioned then returned to service. Luck of the draw.
Probably MCU flash issue. Flash memory can only be written to so many times before failure. So it ages out. Now, why they need to replace the entire MCU is beyond me, it should be possible to swap the memory chip to repair it. I guess they are taking the old one to do that so it will go in another car to be repaired? If you paid $3000, did you get your old MCU back?

I think it's Tesla's efficiency: Just swap the whole component out instead of replacing the chip. It's faster for your technicians but it costs much more for customers.
I think MCU memories are soldered so it takes longer to replace.
