While driving along, sudden stop and "Electrical fault"

[MarcS]

I had exactly the same problem this morning in my 4s (batt +). Been driving for about 5 miles. Battery was at 84%. it just cut out and the same message (in english as I'm in the UK). I stopped, got out, locked the car, unlocked it and everything was fine again. Will report it to the dealer if it happens again. Not good though.

I had the same problem, but didn‘t knew about the lock and unlock after 15 min!
Waited 2 hrs for AA man, then he called tow truck. The tow truck driver then was able to start the car while I was already gone. It went to the dealership, they had it for 5 days and couldn‘t find any problem and they gave it back to me.
After that I had a couple of days later that the volume froze and the technician just disconnected the 12V battery, cleared the faults and then all was OK again.
There is definitely a problem with the battery/software somewhere...
Hope its gone now.

After a brief top up at an ionity charger 60 to 75% I got back on to the M4. In the outside lane I had a warning message and lost ALL power. Luckily managed to get on the hard shoulder between middle lane SUVs and inside lane trucks. I turned off the system, opened the car door, locked and unlocked And everything has been ok since. I know Tesla have had a few problems after Vic high Charge????????

Do you have a '20 MY and have you had the big WMA5 update applied?

Dear forum,

I have been very impressed and happy with my 4s, taken delivery 18 July just outside Oslo, Norway. While driving home from work today, I lost all power, however all instruments were powered on.

The following error message appeared, which translates into: The electrical system of the vehicle is defect. Park the vehicle safely." I tried turning it on and off several times, including several minutes between attempts to try to make the car go to deep sleep. No change. Had to be towed away to the dealer. I know there have been some complaints related to the 12v battery, however this incident happened during driving.

The car had 71% charge, was charged at 1.9 kw for about 8 hours at work just prior to driving, about 16 km (10 miles) when this happened.

Depending on the dealers findings and interventions, I am now very sceptical to drive the car. Any experiences/advice?

I had similar problem with my Taycan 4S, no explanation from dealership
