2025 Polestar 3 Problems: What I Found After Digging Into Owner Complaints
Problem analysis of the 2025 Polestar 3 found issues including repeated AC charging failures, software glitches and unnecessary automatic emergency braking.
Key Points
- Our team analyzed real consumer complaints and NHTSA data to identify commonly reported problems with the 2025 Polestar 3.
- Owners most often report AC charging failures, software glitches, warning lights, and unexpected emergency braking.
- Owners with repeated or unresolved defects may have rights under state lemon laws, including possible refund, replacement, or compensation.
Ah, the classic EV charging problem.
We have been tracking charging problems with the Polestar 3 for a while now with the first complaints started arriving in early 2025. We also launched a class action investigation into the charging defect.
But charging is not the only problem owners are reporting. As I put together this roundup of the most common problems with the 2025 Polestar 3, charging failure stood out as the biggest issue, followed by software glitches, warning lights, unexpected braking, and other problems.
My name is Sergei Lemberg, and I’m a lemon law attorney with over twenty years of experience representing consumers in vehicle defect cases. I reviewed NHTSA complaints, owner feedback, manufacturer communications, and our own internal data to put this together.
I’ll be honest: the Polestar 3 is a sharp-looking electric SUV, and plenty of owners may never run into these problems. But a small percentage of owners do experience serious defects, and we put together these roundups to educate consumers and identify potential lemons.
Let’s dive in.
Most Common Problems
Here are the top problem categories I identified:
- AC Charging Failure: The onboard AC charger repeatedly fails, preventing level 2 home and public charging and forcing reliance on DC fast chargers.
- Software Instability and UI Glitches: Frequent warning lights, error messages, and system resets disrupt normal vehicle operation and impair safety systems.
- Emergency Braking: The emergency braking system triggers unexpectedly during normal driving situations.

#1: AC Charging Failure
As noted above, we have been tracking Polestar 3 charging problems since early 2025, when the first consumer complaints started coming in. The problem typically involves failure of the onboard AC charger, which can prevent owners from charging at home or at many public Level 2 chargers. It can leave owners dependent on DC fast charging and waiting weeks for replacement parts.
Symptoms owners report include:
- Error messages stating “AC charging fault” or “Charging not possible.”
- Loud popping noises when attempting to charge via AC.
- Complete inability to initiate AC charging despite multiple charger tests.
- Repeated replacement of the onboard charger module with failures occurring again after weeks or months.
- Extended downtime as parts are often on long backorder, sometimes 3-4 weeks or more.
Owner Quotes
“AC charger unexpectedly fails and replacement parts take 3-4 weeks to obtain. Lack of AC charging could strand a driver in an area where no DC chargers are available.”
“AC Charging Fail. Unable to use home charger to charge car even after polestar took car in to replace OBC.”
“When the issue occurs there is a loud pop and the AC charging message changes to waiting. It does not go out of the waiting state until the GHCA unit is replaced.”
#2: Software Instability and User Interface Glitches
I have reviewed consistent complaints highlighting software problems from safety features to basic vehicle functions. Here are the most common ones:
- Temporary or persistent warning lights for brakes, suspension, propulsion, and battery system faults.
- Phantom fault messages prompting urgent “stop safely” notices that disappear upon restarting.
- Loss of regenerative braking and sudden disablement of one-pedal driving mode.
- Unresponsive or blank instrument cluster and infotainment displays.
- Malfunctioning driver profiles, including failure to save seat or mirror settings.
- Rearview camera not automatically activating on reverse after shifting between drive and reverse.
- Overly sensitive or false alarms from driver monitoring and lane keeping assist systems.
Notable owner quotes
“The software frequently shows malfunction in critical systems such as suspension and drivetrain which then will randomly disappear with a restart of the car or system.”
“The one pedal driving / regenerative braking would randomly deactivate. I have my car set on high one pedal driving. 99.9% of the time.”
“If you put the car into drive and then back into reverse, the rear parking camera view does NOT come back up. In fact, it requires several additional touches on the car’s infotainment touchscreen to bring the rear parking camera view back up.”

#3: Emergency Braking
In my research I reviewed complaints about the Polestar 3’s emergency braking system activating when there is no apparent emergency. The reports involve sudden braking while turning, driving through intersections, and navigating curved two-lane roads. In multiple cases, vehicles behind the Polestar 3 had to brake hard or take evasive action.
Common complaints include:
- Emergency braking activating without an obstacle in the lane.
- Sudden braking while turning or negotiating curves.
- Warning lights flashing immediately before the vehicle slows or nearly stops.
- Vehicles behind the Polestar 3 having to brake hard or take evasive action.
- Near rear-end collisions caused by unexpected braking.
Owners shared
“All warning lights flashed, my car applied emergency braking, and [the] vehicle behind me took evasive action to the right shoulder in order to avoid a rear collision.”
“The emergency braking was activated and the vehicle came to an almost full stop. The vehicle behind me nearly hit me. There was no reason for this to be activated and [it] nearly caused an accident rather than prevented one.”
What Should You Do If Your 2025 Polestar 3 Is a Lemon?
A lemon vehicle under state consumer protection laws is typically defined as one with substantial defects covered by warranty that impair use, value, or safety, despite multiple repair attempts or excessive days out of service. I recommend owners take the following steps:
- Document All Issues: Keep detailed records of every defect, service visit, repair attempt, and communication with the dealer and manufacturer.
- File Official Complaints: Report problems to the National Highway Traffic Safety Administration and your state consumer protection agency to create an official record.
- Understand Your Lemon Law Rights: Many states provide statutory protections that may entitle you to a replacement vehicle or refund if your car qualifies as a lemon.
- Contact Lemberg Law: We provide free lemon law consultations and offer representation at no cost to you unless we win your case. Lemon law deadlines are strict, so act promptly.
If your 2025 Polestar 3 suffers from unresolved defects like those detailed here, especially with extended downtime or safety-critical failures, I encourage you to call Lemberg Law for a no-cost case evaluation. We will explain your rights, help gather evidence, and guide you through the process to protect yourself and your family.
