The National Highway Transportation Safety Administration (NHTSA) told
Teslarati earlier today that it is investigating 2020 and 2021 Porsche Taycan models for 12-volt battery issues that are leading to a “loss of motive power,” according to an Office of Defects Investigation (ODI) Resume document.
There have been nine total complaints from owners who have driven either 2020 or 2021 Porsche Taycans. According to the ODI document, the 12v battery is losing power and is causing the entire vehicle to halt operation. This has lead to a loss of motive power when the vehicle is in motion but has not resulted in any crashes, injuries, or fatalities, the document says. There have also been a few reports of the same issue from TREAD (Transportation Recall Enhancement, Accountability and Documentation) field reports. The loss of motive power occurs at any speed without warning to the driver.
