Reported symptoms

Vehicle displays propulsion, drive system, or high-voltage warning message
Vehicle enters reduced-power mode, limp mode, or stop-safely condition
Acceleration is limited unexpectedly or power delivery cuts out intermittently
Charging or high-voltage warning appears before or after propulsion symptoms
Polestar app reports vehicle errors or inconsistent status
Service center references inverter, BMS (Battery Management System), high-voltage, drive-unit, or software diagnostics

Questions to ask

Pose these to the service advisor at intake. Request answers in writing or via email.

Were stored, pending, or historical propulsion, inverter, BMS, drive-unit, or high-voltage codes found?
What software version was installed before and after service?
Was the issue reproduced during a road test or diagnostic procedure?
Is the remedy software-only, calibration-related, or hardware-related?
If charging symptoms also occurred, were charging and propulsion diagnostics both reviewed?
Will the service record confirm whether the vehicle is safe to drive after service?

Documents to request

Each item should be received in writing before authorizing repair work.

Service record with technician notes
Diagnostic report listing propulsion, inverter, BMS, drive-unit, and high-voltage codes
Written confirmation of software versions before and after service
Written warranty classification and safe-to-drive confirmation
Parts invoice showing any inverter, drive-unit, BMS, or high-voltage component replacement
Closed service invoice showing final remedy

Pre-service evidence

Capture before drop-off. Once the vehicle leaves your possession, proving prior condition becomes significantly harder.

Photograph propulsion or high-voltage warning messages
Screenshot Polestar app errors or vehicle status inconsistencies
Note speed, road conditions, state of charge, temperature, and whether the event followed charging
Document whether the vehicle entered limp mode, reduced-power mode, or stop-safely condition
Record odometer reading at drop-off and pickup
Retain towing or roadside-assistance records if the vehicle became disabled

Service advisor interaction

Operational notes specific to the conversation at the service desk.

Ask service to document propulsion-system findings separately from infotainment or app concerns.
If the issue cannot be reproduced, request written confirmation that historical codes were reviewed.
A software-only remedy should be documented with before-and-after software versions.
If charging behavior is cited as the cause, request written explanation of how propulsion components were evaluated.
Safety-critical propulsion concerns should not be closed with vague 'operating as designed' language.

Repair authorization

Cautions before signing.

Do not authorize paid propulsion or high-voltage diagnostic work until warranty classification is clarified in writing
If a high-voltage or drive-unit component is quoted, request written warranty determination before approval
Separate unrelated maintenance from propulsion-system work before approval
Review authorization forms carefully before approving additional repairs

Post-service verification

Complete before leaving the service location. Issues that surface after departure are operationally harder to attribute to the visit.

Confirm no propulsion, drive-system, or high-voltage warnings remain after a full drive cycle
Verify normal acceleration and power delivery during a short drive
If charging symptoms were related, verify charging behavior as well
Confirm software version and remedy are documented
Confirm the service record states whether the vehicle is safe to drive
Save the closed service record

Service inquiry — Polestar 2 propulsion / reduced-power concern

Service Department, I am scheduling my [YEAR] Polestar 2, VIN [VIN], for a propulsion or reduced-power concern. Observed symptoms: [DESCRIBE PROPULSION WARNING, REDUCED POWER, STOP-SAFELY MESSAGE, CHARGING CONTEXT, SPEED, TEMPERATURE, AND DATES] Please confirm in writing: 1. Whether stored, pending, or historical propulsion/inverter/BMS/drive-unit/high-voltage codes were found. 2. Whether the issue was reproduced during road test or diagnostic procedure. 3. Software versions before and after service. 4. Whether the remedy is software-only, calibration-related, or hardware-related. 5. Whether the vehicle is confirmed safe to drive after service. 6. Warranty, campaign, goodwill, or customer-pay classification. Please include these findings on the service record. Thank you.

Warranty notes

Polestar 2 propulsion, high-voltage, inverter, and drive-unit components should be evaluated under Polestar's applicable warranty terms for VIN (Vehicle Identification Number) [VIN].
Software-only remedies do not extend warranty unless Polestar states otherwise in writing.
Goodwill repairs do not extend warranty coverage. Confirm classification in writing.
Repeated propulsion warnings should be documented as recurring safety-related service history.

Observational patterns

Propulsion complaints should document speed, state of charge, temperature, drive mode, and whether the event followed charging or an OTA (Over-the-Air software update) update.

If the issue cannot be reproduced, historical-code review remains important because propulsion warnings can clear before inspection.

Reduced-power or stop-safely events should be documented separately from general software inconvenience.
