Quick answer

A steady red light in the Polestar charging socket and a red frame in the instrument panel indicate a charging malfunction; a flashing red light means the vehicle is locked and does not detect a key when you press the button next to the socket.

Safety first

Stop and check this first

  • Never pull forcefully on the charging handle when the socket light flashes red: the connector is still mechanically locked because the locked vehicle has not detected a key.
  • Do not insert tools or touch the contacts inside the vehicle's charging socket if the steady red malfunction light remains after the 4 restart steps, and ask Polestar Customer Support to inspect the port.

Safe checks you can perform

  • Distinguish between a steady red light and a flashing red light
  • Check the status frame and message in the instrument panel
  • Restart charging using the 4 steps in the Polestar manual

Leave these tasks to a qualified professional

  • Do not attempt this professional task: Inspection of the vehicle charging socket, lock actuator, and onboard charger
  • Do not attempt this professional task: Key detection and charging socket unlock button test

What a technician must be able to justify

Technician visit

These are the steps they must carry out and show you. Tick them as they work: if steps are skipped, do not accept a part swap.

These are not instructions for opening or handling the equipment yourself. They are the checks that should support a technical conclusion.

  1. Inspection of the vehicle charging socket, lock actuator, and onboard charger

    What they doPolestar service technicians inspect the charging socket pins, handle lock mechanism, and stored charging fault codes when the steady red light remains after step 4.

    They must show youthe physical condition of the charging socket and the diagnostic readout from the charging system.

    In writingthe root cause of the red charging socket light, stored fault codes, and any socket or charging part repaired.

  2. Key detection and charging socket unlock button test

    What they doIf the charging socket flashes red even with a valid key nearby, the workshop tests keyless antenna detection around the charge port and the release button next to the socket.

    They must show youa successful cable unlock test using the button next to the charging socket with your key present.

    In writingthe test result for key detection at the charging port and any repair to the release switch or lock actuator.

Before accepting a part or repair

Nothing has been shown yet. Do not accept a part swap based on the code alone.

Follow these steps

Note: Follow the documented order. An error code identifies the affected system, but it does not prove by itself which part has failed.

  1. Distinguish between a steady red light and a flashing red light

    No special tools

    Who:
    you, looking at the LED inside the vehicle's charging socket.
    How:
    check whether the socket LED glows steady red during connection or flashes red when you press the unlock button next to the charging socket.
    Result that matters:
    separating a charging malfunction (steady red light) from a missing key detection while the car is locked (flashing red light).
    If the LED flashes red when pressing the button:
    bring the key within detection range of the car before pressing the release button.
    If the LED stays steady red:
    check the instrument panel and the cable connections.
    Evidence to keep:
    a short video or photo of the charging socket LED and the driver display.

  2. Check the status frame and message in the instrument panel

    No special tools

    Who:
    you, viewing the instrument panel from the driver's seat.
    How:
    look at the color of the image frame and symbol by the charging socket in the instrument panel (red for a fault, yellow for waiting, blue for scheduled charging).
    Result that matters:
    confirming whether the instrument panel reports 'A fault has occurred' or whether the socket LED simply turned off after locking the vehicle.
    If the instrument panel shows red ('A fault has occurred'):
    perform the 4-step manual restart sequence.
    If the socket LED does not illuminate at all when plugged in:
    wait a few seconds and check whether the light illuminates or if charging information appears in the instrument panel.
    Evidence to keep:
    a photo of the instrument panel charging status screen.

  3. Restart charging using the 4 steps in the Polestar manual

    No special tools

    Who:
    you, handling only the external charging cable handle in dry conditions.
    How:
    check the cable connection at the socket and power source, then follow the manual steps: 1. Unplug the charging cable from the charging socket, 2. Wait for a moment, 3. Plug the charging cable back into the charging socket, and 4. Check if pulsating green charging starts.
    Result that matters:
    re-seating and locking the connector to clear a connection malfunction as specified by Polestar.
    If the socket LED turns pulsating green:
    charging is in progress normally.
    If the steady red light persists (step 4):
    stop retrying and contact Polestar Customer Support.
    Evidence to keep:
    notes on the power source used and whether the red light happens on another charger.

What it means

In the Polestar 2 (2025) owner's manual, the LED in the vehicle's charging socket and the instrument panel show the current charging status. A steady red light ('Malfunction' / 'A fault has occurred') tells you to check the charging cable's connection to the vehicle's charging socket and power source, then restart charging using a 4-step sequence. A flashing red light means the vehicle is locked and does not detect a key when unlocking the cable via the button next to the socket. The red light alone never proves whether the fault lies in the car port, the cable, or the supply.

  • Charging cable handle not locked in place after yellow wait modePossible

    The manual notes that a yellow light indicates wait mode when waiting for charging to start, for example if the charging cable handle is not locked in place or scheduled charging is configured.
