Cybertruck can't charge through AC and issue happened again after replaced ancillary device cluster

[Haoooc]

I am happily driving my cyber beast for more than a year now, but in April, I noticed I couldn't charge at home but super charger still worked. I realized something wrong with the AC charger. Service center told me the HV harness is shorted and melted but they didn't know why it happened. They ended up replaced everything in the ancillary cluster bay and the issue resolved.

However, same issue happed again in 2.5 months. I am bring in it into the service center tomorrow, but I am worried they didn't root cause the issue last time. The chances are so rare for getting the bad part twice since I don't see any user complaint about it. Anyone experienced similar issue and has some clue what is going on?

Funny - this JUST happened to me after installing 2025.20.6. I'm going to post separately about it, but read your post first.

Hmmm... maybe it is the software issue then? I installed 2025.20.6 over the weekend, but it was charging ok yesterday. Did you see the issue immediately after installing 2025.20.6 or it happened a few days later like me?

In my case I installed it Monday afternoon, and set the truck to charge to 100%, but never needed the truck for anything until Tuesday morning, so it started having issues immediately after the update.

I read somewhere (can't find it now) that there was an issue with an ethernet flex cable connected to the charging hardware that was stretched too tightly so would work itself loose, interrupting communications. I wonder if something in the latest update made it more sensitive to that issue or something.

Just out of curiosity, do you have PowerShare home backup set up? I thought one of the latest updates included something to enable using Powerwalls or something - I wonder if the update included something that wasn't fully tested with every possible combination of charging hardware.

I do have powershare, but I first noticed the issue in a public level 2 charger, so likely not related to powershare.
