What was the 1st “fix” they attempted that was not successful?
The first "fix" was replacing some rings (I think that's the word he used) in the air conditioner that they said the robot in the factory had put in backwards. Also, they said that the air conditioning was not properly cooling the battery because it needed more fluid in it. I still don't have my car after about a month at the dealership. They ordered 8 parts, one of which is on "national back order" with no estimated time of delivery to the dealership. They mentioned some problematic "valves" in the air conditioner.
 
So I had this same issue pop up yesterday. Preconditioned my battery and did a fast charge yesterday at a Tesla charger for the first time. Driving home "Service Vehicle Soon" and "Service High Voltage System" signs started flashing. Dropped the kids off at school this morning and the alerts were still there but disappeared by themselves when I was driving home.

Brought it into a dealer just to be on the safe side. They claimed that it was a valve issue in the cooling system and replaced the valve and coolant. Still seems to be running fine so keeping my fingers crossed.

I've also had the "valve" problem. RIght now my dealership is telling me that a hose connected to the refrigerant that cools the motor leaks because it is not well designed and a whole new design is being manufactured and become available by end of February. Since I've barely had access to my car since mid-December, I am hoping this is the final problem that needs to be solved. My dealership shop contact assured me this is the thing that will fix this problem.
