Polestar 4 Common Problems & Reliability

The Polestar 4 is a radical, coupe-styled electric SUV that famously deletes the rear window entirely, relying instead on a high-definition roof-mounted camera for rearward visibility. Positioned between the Polestar 2 and 3 in size and price, it is the fastest production car the brand has ever built, offering blistering dual-motor performance. In the UK, its unique design and tech-heavy approach appeal to early adopters and design-conscious buyers who want an alternative to the Tesla Model Y. Early impressions suggest excellent build quality and dynamic handling. It perfectly suits tech-savvy buyers who prioritize cutting-edge design and performance over traditional SUV practicality.

Inspection Checklist for Polestar 4 Buyers

✓The digital rear-view mirror is crucial; test it extensively to ensure you can adjust to the lack of a physical rear window.
✓Check the operation of the electrochromic panoramic roof (if optioned), ensuring it transitions from opaque to clear smoothly.
✓Test the sheer acceleration on dual-motor versions to ensure power delivery is smooth and uninterrupted.
✓Inspect the interior sustainable materials for fit and finish, ensuring there are no squeaks or rattles.
✓Verify the infotainment system responsiveness, as it controls virtually every function in the minimalist cabin.
✓Ensure the rear-view camera lens (mounted on the roof) is clear and the washing mechanism works perfectly.
