2022 MG 5 Exclusive Electricity · CF22 HXM

The most recent MOT test on 24 June 2026 resulted in a pass with no defects or advisories recorded, which on the surface presents a clean current roadworthiness position. However, the immediate preceding test on 17 June 2026 failed on a major defect relating to the offside front service brake excessively fluctuating, alongside advisories on both front outer brake discs noting wear, pitting, and scoring. Although the vehicle passed a week later, this sequence indicates that the braking system received attention between the two tests, most likely in the form of caliper or brake mechanism rectification to clear the major failure. The 2025 test also passed without defect, so the overall trend does not yet show a pattern of deterioration, but the sudden appearance of a major brake issue in 2026 warrants close scrutiny. The combination of fluctuating brake performance and pitted or scored discs suggests that the front braking system has been under strain, and a prospective buyer should not assume the matter is fully resolved simply because the current certificate is clean. The recorded mileage of 58,314 miles over approximately four years equates to an annualised usage of around 14,578 miles, which is notably higher than the national average of roughly 7,000 to 8,000 miles per year. This level of accumulation, sustained over a relatively short ownership window, places proportionately greater wear on the consumable and mechanical items most affected by mileage rather than age. Braking components, tyres, suspension bushes, coil springs, wheel bearings, and drivetrain elements such as the electric motor reduction gear and CV joints on an MG 5 will all experience accelerated wear under this usage profile. Furthermore, the MOT history shows consistent annual testing but no extended gaps, indicating the vehicle has been in regular service rather than left standing, which is generally favourable for avoiding corrosion-related deterioration but less favourable for component longevity. The mileage progression between tests should be confirmed via the service book and V5C to ensure it is consistent and free of discrepancies. Given the major brake failure and associated disc advisories recorded in June 2026, the front braking system is the primary area for inspection. A prospective buyer should physically examine the front brake discs for run-out, lipping, and surface condition, as pitting and scoring can progress to uneven friction material contact, leading to brake shudder, vibration through the steering wheel under heavy braking, and pedal pulsation. The offside front caliper and slider mechanism in particular should be checked for free movement, as the fluctuating brake reading is often indicative of a binding or sticking caliper piston or seized guide pins, which if not fully rectified will recur and generate further MOT failures. On a test drive, listen for any grinding, squealing, or rubbing noises from the front wheels when the brakes are released, and feel for the pedal returning smoothly without sponginess or a low bite point, both of which would suggest incomplete repair. Beyond the braking concerns, the higher-than-average mileage profile means that age-related rubber and fluid degradation checks remain highly relevant. Inspect all four tyres for both tread depth, which legally must exceed 1.6mm across the central three quarters, and sidewall condition, as four-year-old tyres can exhibit cracking or perishing even with adequate tread. The 12V auxiliary battery, commonly affected by repeated short discharge cycles on vehicles with high electrical load, should be load-tested, and the condition of the high-voltage traction battery warranted through a diagnostic report where possible. Brake fluid should be assessed for moisture content, as it typically requires replacement every two years regardless of mileage, and coolant should be checked for age and concentration. Finally, examine the suspension for any clonks over speed humps or uneven road surfaces, inspect the underbody and wheel arches for corrosion around jacking points and suspension mounting areas, and verify a complete stamped service history with particular attention to any brake or caliper work carried out between the failed and passed June 2026 tests.
