2021 MG HS Exclusive Phev Auto 1.5L Hybrid electric (clean) · WV21 ABX

The most recent MOT test conducted in May 2025 resulted in a pass, although it introduced a specific advisory regarding the rear brake discs being worn, pitted, or scored. When viewed alongside the 2024 MOT, which recorded no defects, the maintenance trend indicates the onset of wear-related degradation in the braking system. While the vehicle currently meets the minimum legal standards for roadworthiness, the presence of this advisory suggests that the braking components are approaching the end of their optimal service life and will require professional attention in the near future to prevent further deterioration of the braking surfaces. With a recorded mileage of 45,887 miles over a five-year period, the vehicle has averaged approximately 9,177 miles per year. This is considered typical usage for a modern vehicle and suggests a consistent driving pattern rather than extreme high-mileage wear or the detrimental effects of prolonged periods of standing. This moderate mileage profile is generally positive, as it implies the mechanical components, such as the suspension and drivetrain, have not been subjected to excessive stress, yet the vehicle has likely been used enough to keep various seals and moving parts lubricated and operational. During your inspection and test drive, pay close attention to the braking performance, specifically looking for any shuddering through the pedal or a rhythmic grinding noise when slowing down, which would confirm the severity of the scored rear discs. You should also check for any signs of binding calipers or uneven tread wear on the tyres, which could indicate underlying suspension issues such as worn bushes or shock absorbers. Given the advisory, it is highly probable that a replacement of the rear discs and pads will be necessary shortly to maintain effective stopping distances and prevent further damage to the braking hardware. Additionally, because this is a plug-in hybrid, you must verify the service history to ensure that the high-voltage system and the 12V battery have been maintained according to the manufacturer's intervals. Check the tyres for any signs of perishing or sidewall cracking due to age, and inspect the brake discs for excessive corrosion if the vehicle has been parked for long periods. Finally, ensure that the brake fluid has been changed according to the recommended schedule, as moisture ingress can exacerbate the corrosion and pitting noted in the MOT history, potentially leading to more significant hydraulic issues.
