What's wrong?
The Battery Energy Control Module, or BECM, is the software-controlled unit that manages the Polestar 2 high voltage battery during driving and charging. In the 2021-2022 Polestar 2, it helps keep the traction battery connected to the propulsion system, so the electric motors receive power when the driver asks for acceleration.
On affected vehicles, the BECM microprocessor operating system has a software fault. The processor can reset while the vehicle is being driven. When that reset happens, the high voltage system disconnects and the car loses propulsion. Steering and braking remain available, but the vehicle no longer has drive power until the fault condition clears or the vehicle is serviced.
The filing does not identify a warning sign before the reset. The first thing an owner notices can be a sudden loss of propulsion during driving, with normal steering and brake capability still available.
Who's affected?
Covers the 2021 and 2022 model years with the same battery energy control module software for the high-voltage traction battery.
| 2021 Polestar Polestar 2 | high-voltage traction battery |

| 2022 Polestar Polestar 2 | high-voltage traction battery |
| Units affected | 3,457 |
| Field incidents | NHTSA has logged 5 field incidents to date. |
The year and model narrow the scope, but the VIN decides. Check your VIN to confirm whether your specific vehicle is included.
What's the safety risk?
A disconnected high-voltage system can cause loss of drive power while the vehicle is moving, increasing the risk of a crash. Steering and braking remain available, but treat any sudden loss of propulsion as a reason to move out of traffic and arrange service. Repair is free at any franchised Polestar dealer.
What should I do?
- Check your VIN to confirm your 2021-2022 Polestar Polestar 2 is included in this recall.
- Contact a franchised Polestar dealer to schedule the free BECM software update that addresses high-voltage system disconnection and loss of drive power.
- Ask Polestar whether your vehicle needs a dealer visit or can receive the software update over the air.
- Bring the recall notice if you have it, or reference recall number 21V110 and Polestar recall R10079 when you call.
- Drive cautiously until the update is complete, and contact Polestar customer service if the vehicle loses drive power.
What happens at the repair
At the dealer, a Polestar technician updates the vehicle software that controls the Battery Energy Control Module and high voltage system. The software update is free under the recall, whether completed at the dealer or through an over-the-air update. Polestar has a general reimbursement plan on file for owners who already paid for a related software repair. Keep documentation and ask Polestar customer service or the service desk how to submit the claim.
