While driving at approximately 90 mph on XXX on the highway, my 2021 Porsche Taycan (VIN [XXX], 51,730 miles) displayed an electrical system error with the turtle (reduced power) icon. The car received all loss of acceleration, warning message to pull over to a complete stop, and was able thankfully to pull over safely to the shoulder. I took the vehicle to Porsche Atlanta Perimeter on XXX. The technician found fault code P0E9D00, DC/DC converter current circuit 2 short to ground, with an active red warning "Electrical System Fault - Stop Vehicle Safely" stored in the front (A49) or rear (A50) high-voltage power electronics control units. The dealer referenced Porsche Technical Information bulletin TI 2791. The technician reprogrammed both control units, raising the software level from 0021 to 0023, cleared the faults, and test drove 15 miles without reproducing the concern. My VIN is not included in recall [XXX] (AMB5 software error causing loss of motive power), but the symptoms and the fix appear closely related. The dealer also performed warranty reprogramming of the onboard charger, driver assistance, and 12V battery sensor control units during the same visit. I am reporting this because the vehicle may be affected by the same defect while falling outside the recall population. No crash or injury occurred.

Loss of Motive Power
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 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

What 2021 Porsche Taycan owners say
Most recent owner complaints, unedited.
There are currently hundreds (if not thousands) of cars, operating on roads of USA, that at any particular time stop in the middle of the road. The power is cut off and Engine Control Error is displayed on the monitor. This issue has been described many times on Reddit, under Taycan-Engine Control Error threads. The affects 2020-21 Porsche Taycans. As an owner of '21 Taycan, I have run into this issue 8 times in the past 4 months. I have been lucky so far not to cause any incidents. I've brought in my car 3 times to Porsche dealership. The first time, a fix was made, but it did not do anything. The second time I brought it in, I was told that there is a transmission issue, but since the dealership can't replicate this issue, they can't fix it. After the second attempt, I contacted Porsche headquarters, looking for resolution. The customer service requested for me to bring the car back to dealership for additional analysis. After I brought the car to dealership, I waited for over a month and then received an email from Corporate Customer Service- there is nothing wrong with my car. So, I'm still driving a car, that can and will stop at any moment. I warned Porsche corporate that if the next time my car stops for no apparent reason and this leads to an injury or worse, someone at Porsche will be charged with manslaughter. Even though Porsche Corporate knows that these cars are a problem, the company refuses to address this issue and blatantly lies to clients, hoping that no one wants to take on a big corporation. How long will it be, until there is a serious injury or worse happens due to these sudden stops? I have all the communication between myself,orsche corporate and Porsche North Seattle showing the exact dates, when these issues happened, the attempt to fix them, the text message from dealership telling me that there is a transmission issue and lastly the email from Corporate, stating that there are no issues with this car. Please take a look. Thank you.
The vehicle’s battery module became defective and would not accept or hold a charge. When attempting to charge the vehicle using standard charging equipment, the battery system repeatedly failed to initiate or complete the charging cycle. The vehicle displayed charging error messages and/or failed to respond when connected to a charging source. Despite using properly functioning charging equipment and verified power sources, the battery module would not charge. The issue was diagnosed as a defective battery module. As a result, the vehicle became inoperable due to the inability to recharge the high-voltage battery. This defect created a safety concern because the vehicle could unexpectedly lose available driving range and become disabled without warning. The failure rendered the vehicle unusable until the battery module required repair or replacement.
The contact owns a 2021 Porsche Taycan. The contact received notification of the federal safety agency Campaign Number: 24V732000 (Electrical System) and would like to be removed from the recall distribution list. The local dealer and manufacturer were contacted. The vehicle was repaired.

On April 23, 2024, while decelerating gently at a traffic light, I heard a loud “thump” sound from the rear of my 2021 Porsche Taycan. Immediately, the vehicle lost access to the Reverse (R) and Park (P) gears. I was able to slowly coast into a nearby parking lot, but then all gear positions (Drive, Reverse, Neutral, Park) became completely unresponsive. The vehicle was immobilized and had to be towed. At the time of failure, the vehicle had just under 45,000 miles and had received routine maintenance and a recall inspection at a Porsche Center in March 2024. The factory warranty expired only one day earlier, on April 22. Porsche is refusing to cover repairs or provide a loaner vehicle, even though the failure clearly occurred at extremely low mileage and immediately after warranty expiration. The failure pattern matches the symptoms described in TSB #2209 (the federal safety agency ID: 10210797) for the 2022 Taycan, which identifies a known defect where the vehicle unexpectedly shifts from D or R into N or P without driver input. While my vehicle is a 2021 model, the behavior is nearly identical — sudden loss of drivability, unexpected gear disengagement, and major safety risk in traffic. This incident could have resulted in a serious accident had it happened in moving traffic. I am submitting this complaint in hopes that the federal safety agency will investigate whether this known transmission defect also affects 2021 Taycan models, and to ensure Porsche takes responsibility for latent safety defects, regardless of narrowly expired warranty status.
I received a recall notice that my vehicle was affected for a battery cell that needed to be replaced and scheduled a date with Porsche and when I finally took the car in they said it’s not a active recall which seemed odd
I bought this car a few weeks ago and drove only 300 miles so far. I was pulling out of my neighborhood onto the Main Street, when I turned then started to accelerate I received an error saying engine control error and my car came to a screeching halt. The accelerator stopped working and the car made some loud grinding noises and no functions were working.luckily nobody was behind me. I turned off the vehicle and when I powered it back on everything is working as normal. This vehicle was just serviced at Porsche a few days ago before the event
Sudden power electrical failure while driving on a city avenue. The car suddenly had no power, the engine goes off, the sterring become very stiff and there was a message saying electrical system error
