Happened yesterday with my model 3 (2018, dual motor performance AWD, 12,300 miles, v11.0 (2022.12.1)). I was driving home from the grocery store (40 minute RT), and as I was turning into the middle turn lane to drive into my neighborhood (in Fort Lauderdale, off A1A), I hear a large clunking noise & feel a shudder like someone hit the bottom of the car with a baseball bat. I thought I’d been hit from behind but there was no one there. The car rolls another 15-20 feet on momentum and stops. The dashboard screen shows the car icon going into ‘park’ and the following two messages appear: "Electrical system is unable to support all features Shutting down features to conserve energy", and toggles back & forth with the message "Vehicle may not restart Service is required" (3:54pm) The car will not restart. I initiated contact with Roadside Assistance on my phone. The agent asked me to do a 2 minute power cycle (agent includes link with directions), which I completed but nothing changed. The car was essentially bricked in the middle of the road without any warning. The only setting change I had made 10 minutes earlier was for the AC to reach the backseat to cool my dog. ETA for tow truck was 60 minutes.
As I’m waiting for the tow service and directing traffic around the car, the above messages continue to toggle back and forth. I noticed there’s a definite slow down and drag in the power windows, which remain barely operable. When the turn signal was activated, I noticed that even though it appeared on on the dashboard screen, there was no signal appearing in the taillights when I stood behind the car to direct turning cars around me. Of course I was unable to check the brake lights since by then my passenger had walked home with the dog and I was alone. At 4:13pm I see a new message in red on the dashboard: "PULL OVER SAFELY Vehicle shutting down" [LOL] and below that "Vehicle may not restart Service is required", which toggles with the message "Schedule service to replace low voltage battery Software will not update until battery is replaced". (12V battery issue?) Those messages continue to display on the screen until it completely shuts down and screen goes black shortly before the tow truck arrives.
There was no message or warning prior to this event. The car is normally charged at home and I only use Superchargers on long trips (rarely). It was fortunate that it happened on Easter Sunday in the afternoon when there wasn’t heavy traffic on A1A, but it was even more fortunate that it didn’t happen in the middle lane of I95 headed to Miami going 75mph. I would have been toast. I bought the car new in 2018 and I know how it starts. The car wouldn’t start. Although it has full self driving capability, I only use that on highways.
A possible clue to a problem is the outdoor temperature sensor was reading 95°. I believe the warmest it ever got yesterday in Fort Lauderdale was 82°.
IMO Tesla engineers need to develop some emergency workarounds when there’s a possible cataclysmic event, like a faulty rear drive unit, which I suspect this might be.
Still waiting to hear back from the SC after the initial message that it’s ‘In Service’.
