I am reporting a recurring, unresolved propulsion-system fault affecting my 2021 Polestar 2 Dual Motor. Since 2025, this vehicle has experienced repeated electrical and propulsion-system problems, including an incident in November 2025 when the vehicle became immobilized and would not engage Drive or Reverse. That incident was resolved after the 12-volt battery was replaced. During 2026, the vehicle repeatedly displayed the warning "Propulsion System Service Required." These warnings have occurred despite numerous repair attempts involving major high-voltage electrical components. Polestar service documentation identifies diagnostic trouble codes involving the Battery Energy Control Module…

Rear driveshaft/axle shafts failing at 39,000 miles on a 2021 Polestar 2. Symptom is a ticking/clicking noise during deceleration at low speed cadenced to wheel speed. Polestar issued Technical Journal TJ 36854.1.0 in March 2024 acknowledging this as a known issue on 2021-2023 model year vehicles with VST Operation Number 46602-2. Despite this being a documented manufacturer defect, Polestar is not covering the repair outside the bumper-to-bumper warranty period. Quoted $2,547 for both rear axle shafts at an authorized service center. This defect affects multiple vehicles across multiple model years and warrants investigation for a formal recall.

Well backing out of a parking space at the grocery store. My rear camera failed to activate even after several times trying to get the camera to work. I decided to try and back out by just looking over my shoulder, but could not see through the back window and collided into a shopping cart. None of the advanced systems activated no object detection, no camera and no collision warning.

Vehicle Info: 2021 Polestar 2 74,765 mi Software version 5.0.10 About 2 weeks ago, I updated to the newest OTA update 5.0.10, which may be unrelated. 1 week ago, the normal start-up safety procedure flagged the airbag and instructed me to find a service station immediately. I scheduled an appt and I was charged $300 diagnostic fee. It's unclear if the airbags would deploy in a collision based on the fault. The service manager shared with me that there are two reasons for the issue in his experience - 1. the vehicle was in a collision and the sensors fail to lock out or 2. there is wiring under the seat that failed either at the harness or on the wire directly. #1 can be ruled out by the…

Polestar has issued two recalls and claims they fixed the reverse camera issues with a software update, but they have not been remedied. When reversing, the camera screen will still often go blank, freeze, or stutter. I am not confident that the picture I'm seeing on the screen is a real time depiction of the view behind me or is simply frozen. This presents safety issues where the screen may have frozen or gone blank just before someone runs behind the vehicle, and the driver is led to believe there is nothing behind the vehicle.

2021 Polestar 2, consistently the rear back up camera fails to display. In my case the issue did not occur until my car was updated past 3.2.8. The issue is caused by extremely dated hardware. The processor, and memory are insufficient for the more modern software that is being released. I also believe this is why my car will slam on the brakes in reverse when there is no object behind the car while I am reversing. Polestar has released a IHU hardware upgrade in other Polestar markets, but has not given any dates or information for this to be released in the US. A further software update is not going to rectify this issue, unless features are removed to fre up resources. Not a safety…
