2026 Polestar 4 Plus EV RWD Electric · OV26 MKA

The 2026 Polestar 4 Plus EV’s lack of a recorded DVSA MOT history presents a fundamental roadworthiness challenge, as the vehicle has not been formally inspected under UK regulatory standards. Without an MOT certificate, the prospective buyer cannot confirm compliance with legal safety and emissions requirements, including the assessment of critical components such as brakes, lights, steering, and exhaust emissions systems. The absence of any prior test results also means there is no historical trend to evaluate—whether maintenance has been consistent, deferred, or neglected—making it impossible to gauge the progression of wear or the likelihood of recurring issues. The vehicle’s electrical and electronic systems, which are central to an electric vehicle’s operation, cannot be independently verified for functionality or software integrity without an MOT, though the manufacturer’s service records may offer partial insight into software updates or battery health. Given the absence of mileage data, it is impossible to accurately assess annual usage rates or the vehicle’s operational burden. However, the 2026 model year suggests the car is relatively new, with no prior ownership history under UK conditions, which could imply either minimal use or a recent acquisition. Rapid mileage accumulation might indicate high demand for the model, potentially straining components like the electric motor, drivetrain, and battery management system over time, while prolonged periods of inactivity could lead to issues such as battery degradation from disuse or standing corrosion in the electrical harness or undercarriage. Without a clear usage profile, the buyer should proceed with caution, treating the vehicle as a high-maintenance risk until further evidence of regular servicing emerges. For a prospective buyer, the most critical immediate actions involve a thorough physical inspection to address the absence of an MOT and potential hidden defects. First, verify the battery health and electrical system by checking for any unusual noises, vibrations, or performance anomalies during a test drive, particularly focusing on the motor’s operation and regenerative braking efficiency. Inspect the undercarriage for signs of rust or corrosion, especially around the battery pack, drivetrain, and suspension mounts, as standing corrosion can compromise structural integrity and electrical connections. The tyres should be examined for sidewall perishing or uneven wear, which could indicate misalignment or suspension issues, and the tread depth should meet legal requirements (minimum 3mm). Additionally, the brake system should be checked for binding calipers, warped discs, or excessive heat discolouration, as these can develop silently over time. Beyond the physical inspection, the buyer must prioritise time-based servicing for fluids and components that degrade without regular use. The electric fluid (if applicable) and coolant should be checked for degradation, as should the brake fluid, which can absorb moisture and reduce braking performance. The suspension components, including coil springs, shock absorbers, and suspension bushes, should be inspected for signs of wear or failure, as these can lead to clunking noises or poor ride quality. Finally, the vehicle’s software and firmware should be updated to the latest manufacturer version, as outdated systems may be vulnerable to performance issues or security risks. Until an MOT is obtained, the buyer should avoid operating the vehicle on public roads until all safety and regulatory compliance is confirmed, and should consider a professional electrical diagnostic to ensure the EV’s core systems are functioning safely.
