2021 MG HS Exclusive Phev Auto 1.5L Hybrid electric (clean) · WN71 KXB

The latest DVSA MOT test for the 2021 MG HS PHEV Exclusive Auto was conducted on 2026-05-05 and resulted in a pass, with no recorded defects. This follows a consistent pattern of clean MOT results from the previous two tests, held on 2025-05-07 and 2024-09-19, indicating a stable maintenance history. The advisory issued at the 2024 test—rear brake disc wear, pitting, or scoring without significant structural compromise—remains the only recorded issue, suggesting that while the brakes are experiencing normal wear, there is no immediate failure risk. This advisory, however, underscores the need for continued monitoring, as brake discs in this condition may require replacement within the next 12 to 18 months, depending on driving habits and additional mileage accumulation. The vehicle’s recorded mileage of 42,277 miles at the time of this assessment represents a moderate usage rate of approximately 8,455 miles per year, which is typical for a five-year-old PHEV with a hybrid or electric powertrain. The steady annual mileage suggests consistent, moderate use rather than either light or heavy driving, which could accelerate wear on certain components. However, the absence of significant mileage gaps—such as long periods of inactivity—means there is no evidence of prolonged standing that might exacerbate issues like corrosion, fluid degradation, or suspension stiffness. The hybrid/electric drivetrain itself is less prone to wear from mileage alone, but the advisory on the rear brake system still warrants attention, as hybrid/electric vehicles often rely on regenerative braking, which can accelerate disc wear if not managed properly. For a prospective buyer, the most critical areas to inspect during a physical examination are the rear brake system, given the DVSA advisory. Visually check the rear brake discs for further pitting, warping, or glazing, and listen for any unusual grinding or squeaking when braking, which could indicate impending failure. Additionally, inspect the rear brake pads for significant thickness reduction, as they may have already worn down to the backing plate. On a test drive, apply the brakes firmly at various speeds and observe for any pulsation or vibration in the pedal, which could signal warped discs or binding calipers. If the rear brakes are the primary concern, consider having the discs and pads replaced before they reach the point of failure, as this will prevent potential brake failure and ensure consistent stopping performance. Beyond the brakes, the MG HS PHEV’s age and mileage make it prudent to focus on several other routine checks. Inspect the tyres for signs of sidewall perishing or cracking, which can occur even with moderate mileage over time, particularly in colder climates or with prolonged exposure to UV light. Check the tyre tread depth for uniformity and signs of uneven wear, which may indicate suspension or alignment issues. The vehicle’s battery health should also be assessed, as PHEVs can experience reduced capacity with age, and a weak battery may lead to poor acceleration or charging performance. Finally, verify that all fluids—brake fluid, coolant, transmission fluid, and power steering fluid—are at the correct levels and show no signs of contamination or degradation, as fluid changes are often calendar-based for PHEVs to maintain optimal performance. If the vehicle has been in use for several years, consider a comprehensive fluid service to replace older fluids, which can degrade over time even if mileage is moderate. Additionally, check for any visible signs of corrosion on the undercarriage, particularly around the wheel arches, exhaust system, and underbody components, as the MG HS may be susceptible to rust if exposed to damp conditions.
