2021 MG HS Excite Phev Auto 1.5L Hybrid electric (clean) · A26 AFO

The most recent MOT, carried out on 7 July 2026, was passed but returned three advisories: corrosion and surface scoring on both rear brake discs and the off‑side rear tyre being close to the legal tread limit and showing edge wear. The two preceding annual tests in 2024 and 2025 were clean, indicating that the vehicle has generally been maintained to a satisfactory standard, but the emergence of rear‑brake disc corrosion suggests a slight deterioration that should be addressed before it progresses to a failure condition. With a recorded 22 877 miles on a 2021 model, the average annual mileage works out at roughly 4 600 mi per year, which is well below the UK average for a five‑year‑old family SUV. Such low utilisation often points to periods of limited use or extended storage, both of which can accelerate certain age‑related issues despite the modest wear figures. The modest mileage reduces the likelihood of high‑wear component failure, but it also means that parts such as seals, gaskets and rubber components may have aged more from calendar time than from use. When inspecting the rear braking system, verify the actual disc thickness against the manufacturer’s minimum specification and look for deep pitting, rust flakes or uneven wear that could affect heat dissipation. On a test drive, listen for any low‑frequency squeal or feel a pulsation through the pedal that may indicate warped discs or uneven pad transfer. The tyre on the off‑side rear should be examined for tread depth, sidewall cracking and any cupping that could be a sign of suspension mis‑alignment; uneven edge wear often correlates with worn rear‑track bushes or a mis‑adjusted rear toe setting. If the tyre is indeed near the legal limit, budgeting for a replacement set is advisable. Given the vehicle’s age and low mileage, a thorough visual check of the under‑body for corrosion, especially around the rear suspension mounting points, is prudent. The high‑voltage PHEV battery and the auxiliary 12 V battery should be tested for state‑of‑charge and capacity, as prolonged periods of inactivity can lead to sulphation or loss of charge retention. Calendar‑based fluid services should be confirmed – brake fluid, coolant and engine oil typically require replacement every two to three years regardless of mileage. Finally, inspect the suspension bushes, coil springs and shock absorbers for signs of dry rot or leakage, and ensure that the service book shows regular oil changes and any required software updates for the hybrid system. Addressing these points will give a clear indication of the car’s mechanical health and any imminent maintenance that a new owner should anticipate.
