2021 MG ZS Excite VTI-Tech 1.5L Petrol · LB71 AAO

A clear pattern of front brake wear and rear tyre edge wear emerges across the recorded DVSA history of this 2021 MG ZS, framing it as a vehicle with consistent but minor serviceable issues rather than structural concerns. The most recent test on 28 February 2026 returned a pass with a single advisory noting an offside rear tyre worn close to the legal limit and on its edge, suggesting uneven shoulder wear consistent with possible wheel alignment deviation or routine inner-edge consumption. The prior test a year earlier, on 8 February 2025, also passed but flagged the nearside rear tyre in similar terms alongside advisories on both front brake pads for being thin. The intervening failure on 7 February 2025 shares identical brake and tyre advisories but additionally notes wear and pitting on both rear brake discs, indicating they were considered acceptable at that moment but already showing surface deterioration. Across three consecutive annual entries the front brake pads have been flagged twice and the rear discs once, which represents a developing rather than stable picture for the braking system. Mileage stands at 44,074 on a vehicle roughly five years into its life, equating to an average accumulation of about 8,815 miles annually, which sits close to the expected norm for a petrol-powered family crossover in this age bracket. There is no evidence in the recorded testing history of multi-year lay-ups or sudden mileage jumps, and the gaps between annual tests align with typical usage for a car driven regularly but not heavily. At this level of annual use the engine and transmission are unlikely to have accrued significant internal wear, but consumables such as brake friction material, tyres, suspension bushes and anti-roll bar links will have seen natural duty cycles equivalent to a typical urban and suburban driver. The fact that advisories are already appearing on front pads and rear discs at this mileage band is not unusual, but it does suggest that the next owner should anticipate replacement within a reasonable service interval rather than assuming these components were renewed at the last test. For a prospective buyer, the test drive should focus specifically on the braking system and rear suspension geometry given the recurring advisories. Listen for any scraping or grinding from the front wheels during light pedal application, a sign that the thin pads noted at the 2025 tests may now be approaching replacement threshold, and feel for pedal pulsation or judder under firm braking which would indicate the rear disc pitting flagged on the 2025 failure has progressed to a measurable thickness variation. On the road, monitor for steering pull to one side or uneven tracking, both of which could explain the recurring rear tyre edge wear, and inspect all four tyres for feathering or one-sided shoulder consumption which would point to misalignment or worn rear suspension bushes. With the engine running, check for any hesitation or roughness from the 1.5 VTi-Tech unit as it warms, and verify that the handbrake holds the vehicle firmly on an incline given the rear disc condition observed. Given the test history, the most cost-effective precautionary measures before purchase would be a four-wheel alignment check, a visual inspection of rear brake disc condition with a borescope or by wheel removal to measure remaining thickness, and confirmation of front brake pad material remaining. The recorded rear tyre wear on both sides across consecutive years suggests the issue is positional rather than a single impact event, making it worthwhile to check rear trailing arm bushes, coil spring seats and shock absorber mounting points for any deterioration that could be introducing camber change under load. A pre-purchase inspection at a workshop with the vehicle raised on a ramp would be prudent to confirm the absence of corrosion on underbody components and to assess exhaust integrity, neither of which has been flagged in the MOT record to date but which are standard concerns for a vehicle of this age and mileage operating in UK conditions.
