Might be a dead 12V battery, which usually last 3-4 years. If that’s it, a mobile ranger can replace it in about 10 minutes.
Yeah I just called they're on the way. I guess we'll see but if it's a drive unit which is what i'm reading i'm covered anyway

I had the same message in my model 2018 model S 100 D.
I made an appointment to take it in to the service center, but they messaged me to drive the car in immediately to them or If it wasn’t drivable, have it towed there. Fortunately, I was able to drive it. I had all the same problems as you: no regenerative, braking, etc.
First they thought it might be the high voltage battery, and gave me a loaner car. But they ended up replacing the PTC heater to the tune of $2400. (My new car battery was already out.)
I drove the car home only to find it giving me the same error message. Turned out it was the high-voltage battery, which was under warranty. The car had to be towed to a larger service center for safety reasons.
I was told that anytime you get a message like that, you can schedule an appointment, but usually they will message you and tell you to bring the car in right away so they will address it immediately at the service center.

Sheeesh man. They just took the car in. I had it towed just now so just waiting on them to get back to me. Hopefully its the high voltage battery. My low voltage was just replaced
They called me saying it's probably the high voltage battery which is covered so looking like ill be without my car for a few days unfortunately.

Some service centers have no idea what they are doing so don’t be shocked if they come back tomorrow and say it’s something else. That being said, I thought they had these battery issues behind them especially in the 100 packs. 
but BRUH Being without my car for 4-5 days in an 100D loaner is just torture right now. Plus the loaner was FILTHYCool! Brand new HV Battery under warranty
Yeah they put me in an 100D 2018 and it SUCKS. No ventilated seats right now and it was hot AF today. Also disgusting inside someones hair was in the seats and the center console had a bunch of Gunk
Would this mean that my range would be restored to 315? It was degraded to 287… also service is saying basically 15 days to complete the job.. does a battery replacement really take that long? HolyyyyCool! Brand new HV Battery under warranty

Haha I’d like to clarify the car itself doesn’t suck it’s a 100D but rather the situation and the dirt inside sucked
Update: it was in-fact the HV Battery. Said they’re waiting for one to be shipped out to them. Guess I’m waiting on this. If anybody has had experience with major delays for a job like this I would love to know your experienceSome service centers have no idea what they are doing so don’t be shocked if they come back tomorrow and say it’s something else.
