2021 Polestar 2 electrical problems

Filed Oct 14, 2026 · Electrical, Fuel system · PA

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 (BECM), including P0AE300, P0ADB00, and P0C7800. These codes concern high-voltage contactor control and precharge-system operation. Additional diagnostic codes have been recorded in the onboard charging system. Repairs during 2026 have included replacing the Battery Energy Control Module, the onboard charger twice, the high-voltage air-conditioning compressor twice, and high-voltage switching or precharge components. In June 2026, the vehicle was returned following repairs, but the propulsion warning recurred within approximately 50 miles. On September 23, 2026, Polestar Princeton returned the vehicle after replacing the onboard charger for a second time. The service department indicated that the vehicle was operating as designed. On September 25, 2026, approximately two days after this repair, the "Propulsion System Service Required" warning returned. I photographed the warning and notified Polestar Princeton and Polestar Customer Engagement. The warning persisted across vehicle shutdown and restart attempts. I returned the vehicle to Polestar Princeton on approximately September 27, 2026, where it remains. I have not received confirmation that the promised higher-level engineering evaluation

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 vehicle history report and the car was never in a collision. #2 is the only viable reason based on vehicle use. If this is the case, it's a design flaw that must be addressed by the manufacturer. More investigation should be conducted to find the cause (e.g. electronic seat adjustments damaging SRS wiring, faulty electrical components, OTA software patches, etc.). Regardless, it's unacceptable for customers to bear the financial responsibility of an SRS failure.

The On-Board Charger failed under normal conditions, leaving the car unable to be charged by any AC charger, this is a common issue that I have seen reported on several forums, and should be addressed.

The backup camera has progressively been made worse by software updates. It is often nonfunctional, shows a black screen, or excessively flickers, making it hard or impossible to see.

After applying the latest update to fix the recall, the camera and infotainment system performs worsee than before. The rear camera stops displaying almost 95% of the time, the only time it does work is if you get back in the car before the system goes to sleep .

Upon entering the vehicle and starting a drive, inexplicably, no audio sounds were playing inside the vehicle. This includes the infotainment system but also the turn/hazard signal clicking, and likely any additional audible alerts that are necessary to drive safely in all conditions. Volume control did not make any difference. Restarting the infotainment system by holding the home button on the screen bezel for 30 seconds, while still driving the vehicle, and waiting longer for the software to reboot, eventually fixed it. There are additional reports of this online.

Rear view camera unavailable when car is put into reverse. Blank screen or lagging screens when backing up can put myself and others at risk of harm or great bodily injury. Car has been serviced for this recall previously and has not been resolved. Manufacturer will need to upgrade the system hardware because the updates alone do not fix it.

Polestar has issued several software updates over the past year that have resulted in serious safety issues: A previous software recall for issues with the vehicle's backup camera has not fixed the issue. About 50% of the time, the vehicles backup camera flashes, freezes, and then fails while reversing before eventually displaying a "Backup Camera Not Available" message. The issue is that this all happens while reversing in motion, meaning it's distracting and dangerous. Similarly, the vehicle's automatic emergency rear braking engages erroneously about 20% of the time while revering. This happens when the system is slow to respond and seems to mistake shadows as objects. It has almost resulted in causing a collision twice now while I was driving. On occasion, the passenger side mirror will fail to raise from the folded position preventing the vehicle from driving safely. The manufacturer continues to claim that software updates have or will fix these issues, however none have been resolved. These issues are not unique to my vehicle either, as they are widely reported online. The vehicle's software has serious safety issues and needs to be resolved. Thank you.

There was a recall due to the rearview camera not coming on when the car is put in reverse. My car was at the shop 3 times for this issue to be fixed and they are unable to fix it. Now the site says there are no recalls on my car. How do I get this fixed? They should be fined for letting this go for years and still not resolving it. They're still selling cars knowing the issue is unresolved.

This car will periodically lose all interior audio function. This includes safety alerts like parking, forward collision, rear collision, cross traffic, and any other alert you can think of including the sound the turn signal makes. Bluetooth audio and radio also unavailable. This is a commonly documented problem as noted by Polestar enthusiasts on Reddit and other forums. Some can fix the problem by performing a reset of the infotainment system. I have had instances in which resetting this system made no difference. The car was unfit by US safety standards until the next day if lucky enough to see the issue self correct. I have only had this car for 4 months, but every week or so this issue has happened at least once. This is an unrecoverable safety issue with risk of assumed safety features arbitrarily not working.
