2021 MG ZS Excite T-GDI Auto 1.0L Petrol · SH71 FSK

The most recent MOT test on 2025-12-01 resulted in a clean pass with no recorded defects, marking a notable improvement from the previous two tests. However, the vehicle’s history reveals a concerning pattern of recurring issues, particularly the rear coil spring failure in 2025-11-26, which is a critical structural component and a major MOT failure. While the 2024 tests showed advisories related to worn brake discs, these were deemed not seriously weakened, suggesting the wear may be progressive rather than imminent. The combination of a major failure and advisories indicates that the vehicle has not received timely or adequate maintenance, which could lead to further mechanical degradation if not addressed promptly. This trend suggests the owner has either neglected routine servicing or faced delays in addressing component failures, which is particularly concerning given the vehicle’s age and accumulated mileage. The recorded mileage of 44,112 miles for a 2021 MG ZS EXCITE is consistent with typical usage for its age, averaging around 8,822 miles per year, which aligns with moderate to heavy daily use. However, the absence of service records or mileage gaps between tests raises questions about how the vehicle has been maintained. Lower mileage could imply periods of inactivity, potentially leading to issues such as standing corrosion on brake discs, calipers, or suspension components, which can cause binding or uneven wear. Conversely, higher mileage without corresponding service history suggests wear on consumables like brake pads, suspension bushes, and drivetrain elements may have progressed beyond the point where minor replacements could have delayed more costly repairs. The lack of recent service stamps also raises concerns about fluid degradation, such as brake fluid absorption of moisture or coolant system contamination, which can compromise braking performance and engine longevity. Given the vehicle’s history of MOT failures and advisories, the buyer should prioritise a thorough mechanical inspection before purchase. Focus on the rear suspension, particularly the coil spring replacement and any signs of further damage to the lower control arm or bushings, which could lead to misalignment or excessive play. During a test drive, listen for unusual noises such as clunking from the rear axle area, uneven suspension travel, or excessive vibration that may indicate worn suspension components or misaligned wheels. Inspect the rear brake system for binding calipers, corrosion on discs or linings, or a shuddering feel that could signal warping or uneven wear. Additionally, check for fluid leaks around the rear axle, differential, or exhaust system, as these could indicate failing seals or gaskets contributing to further mechanical stress. For the buyer, given the vehicle’s age and the presence of advisories, it is essential to address the brake disc wear and coil spring failure immediately. The worn brake discs should be replaced with new or refurbished components to prevent overheating, warping, or reduced braking efficiency, which is particularly critical in a vehicle of this size and performance class. The coil spring failure is a serious structural issue that must be repaired to maintain ride quality, handling stability, and safety. Beyond immediate repairs, the buyer should schedule a comprehensive service at the earliest opportunity, including a full brake fluid flush, coolant system inspection, and a check of the suspension bushings and struts for signs of wear or damage. Given the lack of service history, it is advisable to verify the condition of the 12V battery, as prolonged inactivity can lead to sulfation or poor electrical connections, and to inspect the tyres for sidewall cracking or perishing, which can compromise safety and structural integrity over time. Finally, the buyer should consider a pre-purchase inspection by a qualified mechanic to assess the full extent of the vehicle’s mechanical condition and to identify any other potential issues that may not have been flagged by the MOT tests.
