2020 Porsche Taycan Power Train

I was making a left turn after being stopped at a traffic light - just a few moments after the turn, all of a sudden I experienced violent jerking motions of the car, and lost all power in the middle of traffic, and rolled to a complete stop. This was an exceptionally dangerous place to just have the car stop responding. I noted an error message "Engine Control Error" with a red ring around it in the rightmost instrument cluster. I turned on my hazard lights; other electrical functions were still working in the car (e.g. music was still playing over the audio system). I power cycled car off and then on again, and cleared the error, and the car drove normally again. The problem did not recur despite driving about 5 miles more on the way home. I have stopped and started car and drove brief periods several times since then without issue. The state of charge was about 75%, having charged last night at home on AC to 80%. Ambient temperature outside was hot today, almost 90 degrees F, and very humid.

My Taycan suddenly lost power while driving on the road on 10/14/2022

My complaint is that the car will not move. I get in the car to drive and the car displays the following message, “ Electrical System Error. Stop vehicle in a safe place.” This has happened on numerous occasions(at least 7) since I received the car on February 10, 2021. Mind you I work from home so I don’t drive it but once a week. I am quite fortunate that thus far it has only happened in my garage. I took the car to the local Porsche dealership for a software update but that was not the solution. It occurred again after the update. I thought maybe it had something to do with the car charger because it usually occurred a couple days after charging the car but I haven’t charged it in over 2 weeks.
