sudden electrical failure. Two times the car has had sudden unexpected power loss. In particular the forward motion of the stopped suddenly, fortunately i was at low speed <20 mph. Both times electrical error message was noted on the driver's center screen. I was able to turn the car off and then attempted several times to turn it back on, eventually the car started. In my opinion there are no precipitating factors. Also fortunately there were no other cars behind me, otherwise i am sure an accident would have happened.

April 27 I tried a launch control and a few seconds into it I got "All wheel drive error. " Engine performance limited." The car slowed and would only drive a maximum of 20mph. It cycled through several screens, one said "Visit workshop". I tried to attached movie and photo, no luck. I let car sit turned off for about 10 minutes, drove it again, no errors. Tried launch control again, no errors. I have a .mov that shows the errors (My son was in the passenger seat so I had him record the errors). I cannot attach an .mov here. I took it into dealer, they said Porsche didn't have a fix for this but they said not to worry about it. It is dangerous to have the car only go 20mph at some random time!

Total electrical shutdown of the drivability of the car. The car in driving traffic came to a sudden stop and doors were lock and would not start until we tried 3 times. A truck behind us had to come to a quick sudden stop to avoid hitting us in the rear of the car! The car was taken to Porsche South bay for understanding the cause of the problem the manufacture was alerted ,Porsche customer care and a case filed. Porsche Service was suppose to report their findings to Customer Care in reference to case file number. They asked me to also bring in the Porsche charging unit to be re-flashed on software in the unit. I have had the car in multiple times for PCM related issues and software updates, during the most recent update they had to replace the entire PCM with a new one. The car was running fine then, then this issue happened. Porsche is continually having issues with this car all related to the PCM, it appear that the car is unsafe and my wife refuses to be in the car. I asked Porsche if they were aware of this problem and they said yes. I asked Porsche for them to look at this car as a Lemon law car, they call this a Buy Back Program. I am still waiting to be told what is next. Porsche is saying the car is safe and has had no accidents, but they know that this car could cause an accident when shutting down with no notice. How is that considered safe? No message appeared till after the car shutdown.

In May 2021, the Office of Defects Investigation (ODI) opened a Preliminary Evaluation (PE) of complaints received alleging a loss of motive power while in motion at any speed with no prior warning to the driver in the 2020-2021 model year (MY) Porsche Taycan electric vehicles. ODI had received 9 Vehicle Owner Questionnaires (VOQs) and several field reports. All complaints alleged that a loss of motive power occurred without warning and error messages about a battery fault displayed during or after the vehicle stalled.In the subject vehicles, a pulse-controlled inverter is mounted on each of the two drive modules on the front and rear axles. The software designed to continuously monitor end-to-end communication between the safety-related electronic control units (ECUs) in the vehicle can, in certain instances, incorrectly and sporadically detect a potentially faulty communication, set an error memory entry, and trigger a shutdown of the power train, resulting in loss of motive power. If this occurs, the affected vehicles display the warning message ?Motor control error. Stop vehicle in a safe place in the instrument cluster.Porsche has corrected the software malfunction in production. Further, Porsche is conducting a safety recall (21V-486) to upgrade the software on vehicles already in the field. In view of the recall action, this Preliminary Evaluation is closed. The agency reserves the right to take additional action if warranted by new circumstances.The ODI reports cited above can be reviewed online at nhtsa.gov under the following identification numbers: 11435775, 11433960, 11431568, 11429897, 11427688, 11426921, 11426902, 11424618, 11424613, 11424296, 11424175, 11424015, 11423458, 11423311, 11422549, 11422463, 11421593, 11421575, 11421494, 11421347, 11420845, 11420788, 11420734, 11420572, 11419756, 11419735, 11419730, 11419721, 11419422, 11418975, 11418935, 11418793, 11418705, 11418692, 11418593, 11418476, 11418405, 11418381, 11418245, 11418237, 11418153, 11418142, 11418132, 11418106, 11415110, 11414731, 11414486, 11404336, 11386164, 11383427, 11377898, 11377875, 11364083
