The PCS is an LRU that sits on the main battery. Primary functions are to convert AC to DC for charging and 400v>12v for the 12v bus. It's modular in that there are a couple of subsystems that make up the PCS but the entire system is contained inside one singular LRU.
The worrying thing is why is a new vehicle facing such problems- is the internal QC of the LRU's and other subsystems so poor that they are entering the production line? Much as I love Tesla cars, I am really getting concerned that they may be cutting corners as they scale up production to keep Wall Street happy.I had the same thing happen to my MYLR 6 days after taking delivery. Our car broke down 100 miles from home. When we went to get back into it, the car wouldn't start. Same warnings as you. They towed the car to a dealer that was only a couple of miles away. After that everything was a pure nightmare. Even though roadside assistance said the dealer would work on the car, when we got there they were reluctant to do so. They wanted to give us Uber credits to get home. Ultimately, they did try to swap out the 12v but it didn't work and they gave us a loaner. It took a week to replace the Power Conversion System. It was very difficult to get information from the repair shop or to get any support from Tesla. My feeling at the end is that Elon Musk has imprinted his personality disorder on the entire company. Tesla did exactly nothing to make the situation easier/better. All of that being said, we love our new Model Y. The only comfort was that in searching for Power Conversion System failures, I could not find much discussion. I'm glad that not many people are having to deal with this.
I agree with you to a point, but every vehicle will have some failures. And a lot of times with electronics, it will fail early if it's going to fail. I think the main thing to pay attention to is what the manufacturer does when it fails.The worrying thing is why is a new vehicle facing such problems- is the internal QC of the LRU's and other subsystems so poor that they are entering the production line?

You're trying to say that would affect the 12V battery system? No, it wouldn't. A/C and heating always run from the main battery. The 12V system is not relevant to that.Have you done a lot of dog mode and camping mode? I think using an AC/ heater while the car is not running wears out the battery fast.
