Owner reports
Selected complaints filed with NHTSA by 2025 Polestar 3 owners, lightly cleaned up (personal details are redacted by NHTSA).
The contact owns a 2025 Polestar Polestar 3. The contact stated that while driving approximately 3 MPH in a parking lot, as he depressed the brake pedal, to slow down the vehicle did not slow down. The contact stated no warning light illuminated. The contact stated that the vehicle jumped a curb and ran over some shrubbery. The contact stated that the passenger side front and rear doors had scraped a light pole, and then the vehicle rolled out of the parking lot and over a retaining wall. The contact stated that the vehicle landed on a sidewalk and then continued out onto a road below the parking lot and finally stopped. The contact stated that a warning had illuminated that his rear driver's side tire had deflated. The contact stated that the lower front bumper had been damaged, and some plastic parts of the driver's side wheel well had broken off. The contact had no personal injuries. …
The Polestar 3 failed while driving with my family on 8/16/25. It had a propulsion failure (with "turtle mode") and it would only go 6 mph or less and would not go up a hill. With nowhere safe to pull over while on the hill, I had to perform an unsafe maneuver to get the car down a hill to a safe place. Once parked it showed dashes on the dashboard and would not go into drive or reverse. The car was towed--it could not be placed in neutral so had to be dragged up the platform. It was in the service center for 24 days and returned to me without anything fixed. I learned 5 days ago that the service center had requested replacement of the VCU which was denied by Polestar engineering. I feel the car was returned to me in an unsafe condition. The failure happened again recently but fortunately it was parked and would not start. No warning lights, just dashes again on the dashboard. …
Date of Incident: [redacted] US Eastern Time Location: [redacted] Incident Type: Safety defect and vehicle malfunction due to Sudden Unintended Acceleration with multiple safety system failures On the date referenced above, while traveling at approximately 5 mph and preparing to park in a gravel parking lot, I removed my foot from the accelerator pedal to bring the vehicle to a complete stop using the normal deceleration process (with One-Pedal Mode disabled). Instead of the expected behavior, the vehicle: 1.Suddenly and violently accelerated without input 2.Drove straight into a parked vehicle at high speed, completely displacing it 3.Continued accelerating despite my attempts to control it 4.Required multiple brake applications before finally stopping 5.Traveled approximately 270 degrees across the parking lot while I desperately tried to avoid additional collisions 6.There were ~6 …
The malfunction I experienced involved the vehicle's electronic safety system, which caused the brake to apply suddenly and without my input. The service center was "UNABLE TO DUPLICATE" the specific fault during their inspection and found "NO CODES STORED," noting that the problem was intermittent and not verifiable by the technician. The car is, however, available for inspection. My safety and the safety of others were put at extreme risk because the car suddenly and unexpectedly applied the brakes while I was driving in the middle of a street, creating an immediate and severe danger of being rear-ended by other traffic. The problem has not been reproduced or confirmed by the dealer. …
I have had multiple issues with my Polestar 3. Most notably, the vehicle lost all propulsion at highway speeds. My safety was heavily jeopardized as I had to merge across multiple lanes of traffic to reach the shoulder. On the day of the incident, the car's propulsion stopped working 4 separate times. The Polestar service center did nothing other than reset the software and tell me the issue was not repeatable. Additionally, the Polestar 3 has consistently electrical issues. I've had doors handles close on my fingers, the rear hatch close on my head, I had a period of time where the driver door did not open, and many basic elements like handsfree calling and bluetooth fail regularly. I also get repeated phantom front-end collision issues where the car automatically jams on the brakes when there is no actual concern for front-end collision. …
Onboard charger (OBC), which is the unit that converts AC power (what home wall outlets have) to DC power (what the battery holds/uses has failed 3 times now in less than a year of ownership. Brand new car, leased from Polestar. 3/21/25 - Picked up car from Polestar Lisle, as soon as I got home from the dealership, it didn't work out of the gate, couldn't home charge. Ever. 5/8/25 - OBC replaced (first time) 6/2/25 - OBC replaced (second time), can't remember when it actually failed. But this was the second repair date. 11/19/25 - OBC failed a 3rd time, first available repair date 12/26. 12/26/25 came and went, no part, no ETA. Meanwhile, I'm stuck having to pay about 3x the cost to charge at various superchargers/DC fast chargers since it can DC charge only. Paying a lease for an electric car that I can't charge at home. …
The vehicle has experienced repeated failures of the high-voltage charging system that prevent normal charging. The first failure occurred at approximately 511 miles, with warning messages related to the charging/high-voltage system and inability to charge reliably using normal AC charging equipment. The vehicle was taken to an authorized dealer/service center and the issue was confirmed. The vehicle was out of service from December 1, 2025 to January 9, 2026 for diagnosis/repair. After being returned, the same charging-related failure reoccurred. The vehicle again went back to the authorized service center and has been out of service from February 10, 2026 to March 4, 2026 and counting. (the issue remains unresolved / parts are on order). Total time out of service is approximately 63 days for the same defect. Current mileage is approximately 1,070 miles. …
Upon purchase of the vehicle, the Onboard AC Charger (officially: "GHCA") failed on the first charge at home, utilizing Volvo (sister company) equipment that has charged another vehicle successfully for 5+ years. The equipment was confirmed still functional on the other vehicle after failure of the Polestar's on-board equipment. The part was replaced during a lengthy service visit, and the failure has reoccurred less than 3 months later with a repair pending for 6+ weeks. Unexplained electrical faults are always a safety concern. Vehicle on-road safety is compromised when pre-planned charging stops are suddenly and unexpectedly unavailable due to the failure of on-board equipment. Low state of charge conditions and being forced to drive on reserve power to arrive at a DC charging point leaves the potential to run out of power in traffic. …
AC charging fails rendering the vehicle unusable when only having access to level 1 and level 2 EV chargers. The onboard charger has been replaced by the Polestar dealer twice. They replaced it once, and it failed to rectify the issue at the dealer; so they replaced it again. After a month of downtime for this issue, we are now on the third onboard charger. Lo and behold, we have the vehicle for three days and it failed again. We've resorted to using DC charging but polestar is now unresponsive to our inquiries. We are uncertain whether they will continue to try fixing the issue. Or if they will just ignore us. Also, we had many other electrical and software issues that also caused another separate month of downtime. In the three months since we had this lease, we've only driven it on and off for one month. …
I have had the vehicle for 4 months with no charging issues. All of a sudden the other day, my car would not charge at home AC 14-50 outlet using the Polestar supplied cable at 48 amp max setting to achieve the 9-11 kW charging rate. I lowered the max amp to 15, and the car started charging at a very slow rate of 3 kW. I also tried plugging my car into a slow Chargepoint AC charger and it would not charge at all. I contacted Polestar service and after a few hours, I was finally able to get a hold of the technician and he said there is a defective OBC that needs to be changed but it would take at least 2 weeks and that he would not have a loaner available for me until May. He said it was up to me if I wanted to still enjoy my car and just deal with it charging slower at home or charge using DC fast charger instead, which defeats the purpose and convenience of having an EV to begin with.
