2026 Polestar 4 Plus EV RWD Electric · OV75 HCU

The 2026 Polestar 4 Plus EV’s official DVSA MOT history remains entirely unavailable, meaning there is no direct record of prior test outcomes, maintenance intervals, or defect trends to evaluate. Without any prior MOT results, it is impossible to determine whether the vehicle’s maintenance history is stable, deteriorating, or improving over time. The absence of historical data also precludes any assessment of whether the vehicle has been subjected to consistent wear patterns, potential neglect, or irregular servicing that could indicate underlying issues. For a prospective buyer, this lack of transparency is particularly concerning, as it leaves significant questions unanswered about the vehicle’s long-term reliability and the extent of any latent mechanical or structural concerns that may not yet have surfaced in testing. Since the mileage is not recorded, there is no basis to compare annual usage rates against the vehicle’s age, which complicates any evaluation of wear progression. Without mileage data, it is not possible to gauge whether the car has been driven at a reasonable pace or if there have been significant periods of disuse, which could accelerate corrosion or fluid degradation. For example, prolonged idling or infrequent use might lead to issues such as standing brake corrosion, battery discharge, or fluid stratification in the cooling or brake systems. Conversely, if the vehicle has accumulated a high mileage without corresponding age, wear items like suspension bushes, coil springs, and exhaust components may show signs of excessive use. The absence of mileage data also means any potential for rapid wear from aggressive driving or off-road exposure cannot be assessed, leaving the buyer with no concrete indicators of how the vehicle’s components are being stressed. Given the complete lack of MOT history, the buyer should conduct a meticulous pre-purchase inspection to address critical areas that are particularly susceptible to age-related or usage-induced failures in an electric vehicle of this generation. First and foremost, examine the tyre condition for sidewall perishing, which can occur even at low mileage due to prolonged exposure to UV light and temperature cycling. Check for uneven wear patterns that may indicate alignment or suspension issues, and verify the tyre pressure and tread depth against legal and optimal standards. The battery system, while not directly inspected in an MOT, should be evaluated for signs of swelling, leakage, or excessive heat, as these are critical safety concerns in electric vehicles. Inspect the brake system for corrosion on discs and calipers, especially if the car has been stored for extended periods, as standing fluid can cause binding or reduced braking performance. For fluid servicing, the Polestar 4 Plus EV’s electric powertrain does not require traditional oil changes, but other systems such as the cooling circuit, brake fluid, and power steering fluid should be checked for degradation. Given the vehicle’s age, if it has been in use, the cooling system’s coolant should be inspected for contamination or sludge buildup, and the brake fluid should be replaced every two years or as recommended by the manufacturer to prevent corrosion within the hydraulic system. The electrical wiring harnesses and connectors should be checked for signs of wear, corrosion, or overheating, as electric vehicles are particularly susceptible to these issues due to their complex control systems. Additionally, the structural integrity of the vehicle’s body should be assessed for any signs of rust, particularly in areas prone to moisture exposure such as wheel arches, door sills, and undercarriage. Finally, a professional diagnostic scan of the vehicle’s electrical systems can reveal any hidden faults or error codes that may not be apparent during a visual inspection, ensuring that the EV’s software and hardware are functioning optimally.
