2025 Polestar Polestar 3

To Whom It May Concern, I am filing this complaint to formally alert the National Highway Traffic Safety Administration to what I believe is a recurring and potentially dangerous defect in the Polestar 3 — specifically, a failure of the air conditioning system. In my case, the A/C began malfunctioning just one month after I received the vehicle. The system frequently fails to cool, blows warm air, or cycles inconsistently — even in extreme heat. This creates a safety and comfort risk, particularly in regions with high summer temperatures. While Polestar has pushed multiple software updates that claim to improve HVAC performance, none have resolved the issue. This is only one of several problems I’ve experienced with the vehicle. There has been a litany of other issues, including software instability, unreliable app connectivity, and system behavior that seems inconsistent with expected performance for a new vehicle. However, the A/C failure remains the most significant and dangerous problem. What’s more troubling is Polestar’s lack of responsiveness. I have attempted to resolve this through customer service and even escalated the matter to their legal department. I’ve received no reply. Most recently, I attempted to have my vehicle towed to the Costa Mesa, California service center using Polestar Roadside Assistance. Despite repeated efforts, I was unable to reach anyone at the service center to coordinate the tow. I was left stranded with no resolution or support. I have now exhausted all reasonable avenues with the manufacturer. Given the combination of a critical HVAC failure, unresponsiveness from the manufacturer, and what appears to be a broader trend among other owners, I urge NHTSA to investigate whether this issue warrants a safety recall or broader intervention. I am happy to provide documentation, including my VIN, service history, and records of my communications, upon request. Sincerely, [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

After being away for a couple days the car has been completely unresponsive. I can not access the car and doors will not open. The car had to be towed and seems to be an issue with electrical powertrain such as 12V battery that is dying for some reason. This should not be the case as car was driven before hand and should have recharged the 12V battery. This is very concerning as this can leave you trapped and have to access to the car while traveling. Please investigate as I've seen many issues with this car.

The system component that failed was the on-board AC charger (OBC). This failure prevents AC charging of the vehicle. The Polestar - Houston service team has confirmed that this hardware needs replacement. There is currently a 2-3 week wait for part, so vehicle is currently sitting at the service center. The dealer has diagnosed and confirmed that the on-board AC charger needs to be replaced. Prior to the failure, there were no warnings or symptoms to suggest that a failure was imminent. Three NHTSA manufacturer communications (DP1035, DP1037, and DP1038) are in reference to this issue.

From the time of purchase, literally since I first got home from the dealership with it, it will NOT AC charge at 110 or 220v. Multiple chargers tested in multiple locations, both home based and commercial (ChargePoint, etc), none will charge. DC fast charge works fine. Stuck with just having to DC fast charge exclusively. Took it to the dealer, took them about 1.5 hours to finally believe me, but they have identified it, but the module that needs replacement is on back order, so stuck DC charging at about 3x the home charging cost for the time being. Very frustrating on a brand new car. Reference prior NHTSA manufacturer communications (DP1035, DP1037, and DP1038).
