Polestar Polestar 4
2026–2026
Data Availability
Milemark has only 5 classified NHTSA complaints for the 2026 Polestar 4 in our database. This is a new model that began production recently, so limited complaint data is expected. This does not mean the vehicle is reliable or unreliable—we simply lack the owner-reported data to assess real-world failure patterns. All 5 complaints relate to electrical systems and ADAS sensors, but drawing conclusions from such a small sample would be misleading.
What We Know From Recalls
No recalls are currently on record for the 2026 Polestar 4. This is typical for a newly released model, as recall campaigns often emerge months or years after production begins.
Warranty Extensions and Technical Bulletins
There are 21 technical service bulletins on file for this model. TSBs document known issues and repair procedures that dealers use to address them. For a vehicle this new, TSBs often cover software updates, calibration procedures, and early production quirks. Review these bulletins with a Polestar dealer or independent technician familiar with the brand to understand what they address.
How to Research Further
Given limited data, schedule a pre-purchase inspection with a technician experienced in EV diagnostics. Check Polestar owner forums for emerging patterns. Verify the vehicle's VIN history and ensure all TSB updates have been applied. Ask the selling dealer specifically about the 21 bulletins on record.
Trends
Complaint trends by era
Click a window below to see complaint data scoped to just those years.
5-year windows, not manufacturer generations — this database doesn't have reliable platform/redesign data to draw real generation boundaries from. Recent model years show fewer complaints mainly because they have been on the road less time, not necessarily because they're more reliable — read this as complaint volume and mix by era, not a reliability trend.
What breaks, and when
Onset mileage not consistently reported.
Typically $250–$5,240 to fix a electrical repair, nationally.
From owner-filed complaints to NHTSA, not independently verified. Federal mileage reporting on recent complaints is sparse — see methodology. Cost ranges are national estimates from book labor hours and parts pricing, not this vehicle's actual repair history — they don't account for your location or shop type.
