Owner complaint summary

I was stopped at an intersection waiting for traffic. There was a small opening in traffic, and I accelerated rapidly from a stop while making a left turn to enter traffic when the "engine/motor" suddenly completely died, and the car quickly came to a stop. The dash displayed a message: "Engine Control Error. Park vehicle in a safe place." Had there been a semi-truck that could not stop behind me, there would have been a collision. I turned the car off and then back on, and was able to drive the car. I had it serviced at Hennessy Porsche in Atlanta. They "reprogrammed" the car. I showed them some reports from the Taycan Forum of other incidents where this problem occurred, including one from a mechanic in the UK, which is attached. https://www.taycanforum.com/forum/threads/explained-wna5-drive-system-control-fault.25777/ This report states that once the problem occurs, it cannot be fixed with reprogramming. I have no idea whether he is right, but the post he made includes significant details about the problem. If what happened to me happens again to me or anyone else with this model car, an accident is bound to happen and likely be bad.
