What's wrong, in plain English

In some Polestar 2 vehicles, the microprocessor in the Battery Energy Control Module can reset itself. When the microprocessor resets, it can cause the vehicle's high voltage system to disconnect. If the high voltage system disconnects, the vehicle can lose the power it needs to keep moving, resulting in a loss of drive power while the vehicle is being driven.

2. Contact a dealer, or call Polestar customer service at 1-800-806-2504.
3. The software update is free, delivered by a dealer or over-the-air.

Where do I find my VIN, and what do I tell the dealer?
