I had the same issue. If you go to the ALERTS you will see all the errors. I guarantee there were about 15+ errors because the item that is faulty is connected to numerous systems. However, if the vehicle is not with you, you can't check and see it. Drove it three times and had three breakdowns. You can do the reset. It will only buy you time until it happens again. Luckily for my when it happened I was going 25 mph, 41 mph and 13 mph.
My Cybertruck was towed in and they identified the problem. It is the "Bed and Backbone Harness - Harness - LV Backbone". That is what they call it. It is the Low Voltage (48v) Harness which many other systems reply on, so once that goes, everything else has to trigger an alert/error. The part was faulty and had to be special ordered from Austin.
What I don't know is if the replacement part the same part or a new & improved part. If it is a new & improved part, folks are going to be lining up for it or some sort of recall. If it is the same part, I think it is more of a hope that it was a rare occurrence as others driving 1000's of miles haven't had that issue. I think if one of the folks who gets the repair comes back for the same issue shortly there after, they probably have a problem on their hands. Only time will tell.
According to the service manual it is a 78 step process to get to the Low Voltage Harness and to put everything back. They actually have to remove a lot of stuff. My Cybertruck is close to being finished, so I will report back as I have updates.
