2021 Polestar 2 Electricity · OY21 XSB

The vehicle recently passed its MOT on 17 March 2026, but the history highlights a clear and escalating issue with the braking system that requires your immediate attention. With approximately 5,971 miles covered per year, this car has been used lightly. However, the low mileage does not correlate with the rate of wear on the brake components. In February 2025, the tester flagged the offside rear brake disc as worn, pitted, or scored. By the most recent test in March 2026, this deterioration had spread, with advisories now listed for both front and rear brake discs. This pattern suggests the braking condition is worsening. The progression from one affected disc to all four within a year implies the discs may be corroding due to lack of use or the material is degrading faster than expected. You should budget for a full brake disc and pad replacement in the near future. The history also reveals a significant safety failure in March 2024 related to tyres. At that time, the offside rear tyre was dangerously worn with exposed cords, and the nearside front tyre had a cut reaching the ply.
