2022 MG HS Excite 1.5L Petrol · DS22 AAN

The 2022 MG HS EXCITE’s latest MOT test on 2026-01-07 resulted in a clean pass, but the presence of identical advisories regarding both nearside and offside rear brake discs—described as worn, pitted, or scored but not seriously weakened—indicates a persistent but stable maintenance concern. Over the past year, these advisories have remained consistent, with no evidence of worsening wear or failure progression, suggesting either controlled braking habits or a naturally gradual thinning of the discs. However, the lack of a subsequent MOT failure in this period does not absolve the buyer of due diligence; the advisories imply that the discs are approaching the point where they may require replacement within the next 12 to 18 months, particularly if the vehicle experiences heavier use or prolonged periods of braking stress. The absence of any other MOT failures or critical defects in the history further supports that the vehicle’s structural and functional integrity remains intact, but the brake system’s long-term reliability hinges on addressing this wear. The recorded mileage of 22,114 miles for a vehicle aged four years represents a relatively low annual usage rate of approximately 5,528 miles per annum, which is notably below the average for its class. Such low mileage can stem from infrequent use, long periods of stationary storage, or a preference for alternative transportation methods, but it also raises questions about potential underlying issues that may have been exacerbated by reduced movement. For instance, standing for extended periods can accelerate corrosion in brake systems, particularly on the rear wheels where moisture and road debris accumulate, leading to the observed pitting and scoring. Additionally, low mileage may mask wear on consumables like brake pads, suspension components, and fluids, which could otherwise be more apparent under higher usage. The vehicle’s maintenance history, however, does not reflect any signs of neglect or rapid wear accumulation, but the buyer should be cautious about the implications of prolonged inactivity on components like seals, gaskets, and lubricants, which may degrade over time even without active use. To proceed with a thorough inspection, the prospective buyer should prioritise checking the rear brake system for signs of further deterioration or binding. During a test drive, listen for uneven brake pedal travel, excessive vibration or shuddering during braking, or a grinding noise that could indicate metal-to-metal contact with the discs or pads. Visually inspect the rear brake discs for any signs of excessive heat warping, cracking, or uneven wear patterns that deviate from the previously noted pitting. If the discs are confirmed to be worn to the point of requiring replacement, the buyer should budget for a new set, as the MG HS’s rear disc thickness is typically around 2.5mm to 3mm, and the advisories suggest they are approaching this threshold. Additionally, verify that the brake pads are not glazed or excessively thin, and check for any signs of fluid leakage from the brake master cylinder or calipers, which could indicate hydraulic system issues. Beyond the brake system, the buyer should conduct a comprehensive physical inspection of the vehicle’s structural and functional components, given its age and low mileage profile. Examine the tyres for sidewall cracking or perishing, which can occur even with low mileage if the vehicle has been stored in suboptimal conditions or exposed to prolonged UV light. Check the tyre tread depth for uniformity, as uneven wear can signal suspension or alignment issues, and ensure there are no signs of bulges or cracks that could compromise tyre integrity. Inspect the suspension for signs of wear, such as cracked or seized suspension bushes, coil spring corrosion, or excessive play in the struts. Pay particular attention to the rear suspension, as the advisories suggest potential stress points in that area. Furthermore, verify the condition of the 12V battery and associated electrical systems, as prolonged inactivity can lead to corrosion on terminals or a weakened battery, which may not be apparent until use is resumed. Finally, consider scheduling a fluid top-up or replacement for the engine oil, transmission fluid, and coolant, as these fluids degrade over time regardless of mileage, and their age should be assessed based on the vehicle’s last service date or calendar-based recommendations. If the service book is missing, the buyer should request a full service history to confirm that time-based maintenance tasks, such as valve adjustments or timing belt replacements, have been completed.
