2019 MG ZS 1.5L Petrol · HA07 CON

The latest DVSA MOT recorded for this 2019 MG ZS was conducted on 23 January 2026 and resulted in an initial Dangerous failure, primarily because both front tyres were found to have tread depth below the statutory minimum of 1.6mm, alongside an advisory noting that the offside rear tyre was worn close to the legal limit and worn on its edge. The vehicle subsequently passed on the same date, indicating that remedial work was carried out prior to the final assessment. Looking at the broader test history, the trend shows a generally stable maintenance profile with three clean passes in 2024, 2025, and early 2026, but with a clear pattern of brake disc wear advisories appearing on the rear axle in both 2022 and 2023, followed by the more recent and more serious tyre-related failure. While the vehicle has not yet shown signs of deterioration into structural corrosion or major mechanical faults, the recurrence of braking and tyre wear issues warrants close attention, as it suggests that consumable components may not be receiving scheduled replacement at appropriate intervals. Recorded mileage stands at 41,424 miles over approximately seven years, equating to an annual average of around 5,900 miles, which is markedly below the typical UK mileage for a vehicle of this age and category. Such low usage can be interpreted in two ways: the vehicle may have been used predominantly for short urban journeys, which accelerates wear on components like brake discs and tyres due to frequent low-speed stops and insufficient heat cycling, or it may have been laid up for extended periods, which introduces different concerns relating to standing corrosion, fluid degradation, and battery health. The recurring rear brake disc pitting noted across two MOT assessments is consistent with the first of these scenarios, as discs that are frequently used for light braking without ever reaching sufficient operating temperature tend to develop surface corrosion and pitting more readily than those on regularly driven vehicles. For a prospective buyer, the immediate priorities should centre on the items that have triggered advisories or failures within the MOT record. The front tyres had worn down to a dangerous level, and an advisory remained on an offside rear tyre, so any inspection must include a thorough examination of all tyres fitted at present, confirming not only that the tread depth comfortably exceeds the legal minimum but also that the wear pattern is uniform across the axle. Uneven or inner-edge wear would suggest issues with wheel alignment, suspension geometry, or worn suspension components such as bushes or springs. The fact that the rear brake discs were flagged as pitted on two consecutive tests points towards ongoing surface degradation, which can progress into brake shudder, reduced effectiveness under heavy use, and ultimately necessitate disc replacement. On a test drive, listen for any pulsation through the brake pedal, any grinding or scraping noises at low speed, and confirm that the vehicle pulls evenly under braking rather than drifting to one side. It is also worth checking visually that the rear calipers are not binding, as seized caliper slide pins will accelerate pad and disc wear unevenly. Given the low annual mileage, additional age-related inspection points are highly relevant regardless of the MOT history. Tyres more than five years old can suffer from sidewall perishing and cracking even when tread remains adequate, so production date codes on the sidewalls of any tyres currently fitted should be verified. The 12V battery on a low-mileage vehicle is prone to repeated shallow discharge cycles, reducing its service life, so it is sensible to have the battery load-tested before purchase. Brake fluid absorbs moisture over time and should be renewed every two to three years irrespective of mileage, so service records should be examined to confirm this has been carried out. Coolant and automatic transmission fluid, where applicable, also degrade with calendar age and should be checked for condition. With the MOT record showing no advisories relating to corrosion, suspension, or structural integrity, and given that the vehicle has passed its tests consistently, the overall mechanical outlook remains reasonable, provided that the noted brake and tyre wear points are addressed and the age-appropriate servicing items are confirmed up to date.
