Polestar achieved an impressive second place in the manufacturers list from the 2023 Driver Power survey but the Polestar 2 was the brand’s only car at the time. These results will be expanded upon when the Polestar 3 and Polestar 4 have bedded-in to truly give us a better indication of what owners think of their cars.

Running costs, safety features, powertrain ,road handling and driving pleasure have all been strong points of Polestar 2 ownership and we’d be surprised to see a big difference with the brand’s latest cars. 69 per cent of Polestar 2 drivers experience some sort of fault within the first year so we’re hoping reliability will be improved upon for both the Polestar 3 and Polestar 4. 

Along with 12 exterior sensors, there are 11 cameras and a front radar on the Polestar 4, all helping to provide systems like the collision avoidance, lane keep assist, adaptive cruise, driver alert and post-impact braking with as much information as possible to work well. All the safety systems are featured as standard in the Polestar 4, including seven airbags and even an interior radar to help prevent children and animals being accidentally left inside.

Warranty

The Polestar 4's warranty is an industry-standard three years or 60,000 miles. The battery has a separate warranty of eight years or 100,000 miles - whichever comes first. If the battery’s state of health drops below 70 per cent during the first eight years, it will be replaced at no cost. 

Servicing

The Polestar 4 comes with free, scheduled maintenance for the first three years or 31,250 miles - whichever comes first. The service schedule for the Polestar 2 (we expect the same for the Polestar 4 after the first three years) is every two years or 20,000 miles. There are currently 93 Polestar service points in the UK.
