2021 MG ZS Exclusive EV Electric · OV71 FTT

The 2021 MG ZS EV received its most recent MOT test on 2026-07-01 and passed without any defects, marking a clean result following a history of consistent MOT approvals. While the advisories from previous MOTs—particularly the repeated nearside and offside tyre cracking or perishing—suggest a pattern of minor tyre degradation, these findings do not indicate a deterioration in roadworthiness or structural integrity. The absence of failures or more severe advisories in the latest test reflects a stable maintenance profile, though the tyre-related advisories warrant closer attention during a physical inspection to confirm whether they are isolated incidents or signs of underlying wear patterns. The vehicle’s recorded mileage of 32,782 miles at the time of this assessment aligns reasonably well with its age, averaging approximately 6,556 miles per year, which is within the expected range for a car of this generation. This usage rate suggests moderate, consistent driving rather than extreme conditions that would accelerate wear on components like brakes, suspension, or drivetrain elements. However, the presence of tyre advisories from prior MOTs—particularly at relatively low mileage—could imply either prolonged periods of low activity, leading to tyre perishing from exposure to oxygen and UV degradation, or occasional high-speed driving that accelerates sidewall wear. For a 5-year-old EV, the suspension and electrical systems are likely in robust condition, but the tyre advisories prompt a review of storage practices or driving habits that may have contributed to their condition. For a prospective buyer, the most critical inspection should focus on the tyres, as the repeated advisories indicate potential perishing or cracking, which can compromise grip and safety, especially in wet or adverse conditions. Visually inspect the tyre sidewalls for signs of dry rot, delamination, or separation from the tread, and check for any visible cracks or flaking along the sidewall edges. On a test drive, listen for unusual tyre noise or vibrations, which could signal uneven wear or internal damage. If the tyres appear significantly degraded, consider replacing them before they reach critical failure, as EV tyres, while durable, are not immune to the same ageing processes as internal combustion engine vehicles. Additionally, since the vehicle has been driven at a moderate rate, check for any signs of standing corrosion on the undercarriage, particularly around wheel arches, exhaust components, and the battery terminals, as prolonged idling can accelerate rust formation. Beyond the tyres, given the EV’s age and mileage, a thorough inspection of the battery health is prudent. While the MG ZS EV’s battery system is designed to last the vehicle’s lifespan, prolonged periods without use can lead to reduced capacity or internal degradation. Test the 12V battery by ensuring it holds a charge when the engine is off and the ignition is on, and check for any signs of swelling or leakage around the battery terminals. Fluid checks are also essential, particularly for the brake fluid reservoir, as EV brake systems rely on hydraulic pressure, and fluid degradation over time can lead to reduced braking performance. Finally, verify that the service book contains the latest stamps for fluid top-ups, such as coolant and brake fluid, which should be replaced at the manufacturer-recommended intervals, even if the MOT history is clean. If the vehicle has been stored for extended periods, consider a professional inspection of the electrical system to ensure all connections remain secure and that the battery management system is functioning correctly.
