What's wrong?
The power electronics in affected 2020-2021 Porsche Taycan vehicles are the inverter controls mounted on the front and rear drive modules. In plain terms, they manage how electric power reaches the drive motors, so the car can turn battery power into movement when you press the accelerator.
In NHTSA campaign 21V486, the problem is software inside that control system. The monitoring software can read the communication between components incorrectly, detect a fault that is not actually present, and shut down the powertrain. When that happens, the Taycan loses motive power instead of continuing to drive normally.
The warning sign is a message in the instrument cluster: "Motor control error Stop vehicle in a safe place." If that message appears, the vehicle is telling you the drive system has detected the fault condition tied to this recall.

A matching year and model does not guarantee inclusion. Check your VIN to confirm whether this recall applies to your specific vehicle.
What's the safety risk?
Loss of motive power increases the risk of a crash because the vehicle can stop responding as expected in traffic. If the instrument cluster shows "Motor control error Stop vehicle in a safe place," pull over safely and contact a Porsche dealer before continuing. Repair is free at any franchised Porsche dealer.
What should I do?
- Check your VIN to confirm your 2020-2021 Porsche Taycan is included in this recall.
- Contact a franchised Porsche dealer to schedule the free software update for the power electronics and engine control unit; this addresses the false fault detection that can shut down the power train.
- Bring the recall notice if Porsche mailed one. If not, reference recall number 21V486 and Porsche recall AMB5 when you call.
- Drive cautiously until the software update is complete; loss of motive power increases crash risk.
What happens at the repair
At the dealer, a Porsche technician updates the power electronics software and reprograms the engine control unit so the monitoring system does not incorrectly shut down the power train. The software update and labor are free under the recall. Out-of-pocket repairs already paid are handled through the existing warranty, not through a separate reimbursement program, because the subject vehicles are under warranty. Ask the service desk how warranty coverage applies if you have prior repair paperwork.
