Official inquiries.
An investigation is an inquiry into a potential concern. Its presence does not establish a defect, and a closed case does not certify a car’s condition.
Loss of Motive PowerPE21013
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
