Polestar 4 EVs Recalled Over Faulty Brake System

Polestar Automotive, owned by Volvo Cars, issued a recall on 1,867 units of its electric cars in China. The country's State Administration for Market Regulation (SAMR) announced the recall affecting the Polestar 4 EV models.

The SAMR said the vehicles were manufactured in China between Nov. 29, 2023, and Feb. 1, 2024. According to Teslarati, the recall is effective immediately.

Cause of the Recall

Based on the reports, the electric vehicles were recalled due to a potential problem with software in the all-electric crossover SUV’s brake controller. The software in the affected Polestar 4 units may be defective and may lead to the deterioration of the brake control.

The defect may also cause other features to malfunction, such as the electronic brake assist. The market regulator also announced that the potential defect in Polestar 4’s brake controller software may be a serious safety hazard.

To prevent untoward incidents, the SAMR advised owners that if they encounter any issue with the brake system or the EV’s display shows the malfunction indicator, they must drive on the road at a big gap or distance from other vehicles. Drivers must also apply more pressure than normal when using the brake pedal.

Remedy for the Brake System Issue

As per The Brake Report, Polestar will rectify the problem at no cost to owners of the affected Polestar 4 EVs. There is no need to visit car dealers for this as the automaker will fix the brake system remotely through software upgrades via Over-The-Air (OTA) technology.

Polestar will contact the owners to schedule a free software upgrade at an appointed service center for units that cannot receive the OTA update.
