2021 MG ZS Excite EV Electric · SW21 NHO

The most recent MOT test on 2026-06-18 resulted in a clean pass, though it included an advisory regarding the near-side front lower suspension arm ball joint exhibiting slight play—an issue that has persisted from the last two MOTs, indicating a recurring concern rather than a one-off anomaly. While the vehicle has otherwise maintained a stable MOT history, with no defects recorded in the most recent test and only advisory items present, the consistent presence of brake pad wear and disc pitting on both rear axles suggests a pattern of ongoing brake system degradation. This trend warrants careful attention, as persistent thin brake pads and pitted discs can lead to reduced braking efficiency, increased stopping distances, and potential structural damage to components if ignored. The suspension advisory, while not failing the vehicle outright, signals that the near-side front lower suspension arm ball joint may require imminent attention to prevent increased play, which could compromise steering stability and contribute to uneven tyre wear or suspension failure over time. The vehicle’s recorded mileage of 21,882 miles at a mere 5 years old represents a notably low annual usage rate of approximately 4,376 miles per year, which is unusually low for a car of this age and model. Such low mileage often correlates with periods of prolonged inactivity, where components like brakes, seals, and fluids may degrade more rapidly due to standing corrosion, oxidation, or fluid breakdown. For instance, brake discs and pads can corrode or bind when stationary for extended periods, leading to reduced performance or even failure to clear the rotor entirely upon reactivation. Additionally, suspension components exposed to moisture and road debris for long durations may develop rust or wear more aggressively, exacerbating issues like the ball joint play observed. The lack of significant mileage accumulation also raises questions about whether the vehicle has been subjected to rigorous driving conditions, which could have accelerated wear on drivetrain, exhaust, or electrical systems. Given the recurring advisories on brake components and suspension, a prospective buyer should conduct a thorough inspection of the braking system, focusing on the rear axle area for signs of brake pad thickness, disc warping, or corrosion. During a test drive, listen for uneven braking performance, a grinding noise when applying the brakes, or a pulsating sensation through the pedal, which could indicate warped discs or binding calipers. The suspension should be checked for excessive play or clunking noises when driving over bumps, particularly on the near-side front lower arm, as this may suggest further deterioration of the ball joint or associated bushings. Immediate attention to brake pad replacement and disc refurbishment or replacement is advisable, as the current wear levels could compromise safety. For the suspension, consider a professional inspection of the ball joint and related suspension components to assess the extent of the play and whether replacement is necessary to prevent future handling issues. For a vehicle with such low recorded mileage, practical checks should extend beyond the MOT advisories to address potential age-related wear and tear. Begin with a visual inspection of the tyres for signs of sidewall cracking or perishing, which can occur even with low mileage if the vehicle has been stationary for prolonged periods. Check the tyre tread depth for uniformity and signs of uneven wear, which may indicate suspension or alignment issues. The battery should be tested for voltage and capacity, as low usage can lead to reduced charge retention or internal corrosion. Inspect the exhaust system for leaks or corrosion, particularly around the catalytic converter and tailpipes, as standing emissions can accelerate rust formation. Additionally, since the vehicle has not undergone regular servicing, verify the service book for any missed fluid top-ups or replacements, such as brake fluid, coolant, and transmission fluid, which degrade over time regardless of mileage. Finally, a thorough check of the electrical system, including lights, indicators, and the charging system, is prudent to ensure all components are functioning correctly, as prolonged inactivity can lead to battery drain or faulty wiring issues.
