— A Porsche Taycan recall includes about 43,000 cars after about 130 cars lost power without warning. About 10,300 of those Taycans are recalled in the U.S.
The 2020-2021 Porsche Taycans have software problems that can incorrectly detect a faulty communication and cause the cars to lose motive power.
The National Highway Traffic Safety Administration (NHTSA) opened an investigation in May after 2020-2021 Taycan owners filed complaints about their cars losing power, with some owners claiming they couldn't restart the vehicles.
The Taycan has a pulse-controlled inverter mounted on each of the two drive modules on the front and rear axles. But a software problem can incorrectly detect a potentially faulty communication, set an error memory entry and trigger a shutdown of the powertrain.
A Taycan driver will see a warning message that says, "Motor control error Stop vehicle in a safe place." Porsche says if the vehicle stalls it can be immediately restarted by pushing the On/Off button.
Although about 130 Taycans have lost power, Porsche says it isn't aware of any crash or injury reports.
Some customer cars have already received the software updates and Porsche already made changes during production.
As it stands, the software update will have to be performed by a Porsche dealer and is not available over-the-air. Porsche says Taycan owners will likely have to wait an hour for the software update to be completed.
Porsche dealers will reprogram the power electronics and engine control units after the automaker has mailed recall notices August 27, 2021.
Porsche Taycan owners may contact Porsche at 800-767-7243 and refer to recall number AMB5.
