2018 MG ZS 1.5L Petrol · CP68 PXA

The 2018 MG ZS presents a mixed maintenance picture, with a clear and worsening trend in structural corrosion that demands caution. The most recent test on 12 February 2026 at 78,735 miles passed, but the tester flagged corrosion across multiple critical areas. The vehicle structure itself is corroded, though structural rigidity is not yet significantly reduced. The front subframe mounting area and the subframe itself are both corroded, and both front suspension arms show the same condition. This is not a new problem. Looking back, the October 2024 test at 66,770 miles already identified corrosion in the rear structure near the coil spring hangers, along with corroded front suspension arms and rear disc back plates. The fact that corrosion advisories have spread from the rear to the front subframe and suspension arms over roughly 18 months suggests an active and progressing issue, not a stable one. The mileage accumulation is consistent and unremarkable, which makes the corrosion trend more concerning. The vehicle has covered approximately 78,735 miles over eight years, averaging just under 10,000 miles annually. The record shows steady progression from 51,734 miles in October 2023, to 66,770 miles in October 2024, to 70,851 miles in February 2025, and finally 78,735 miles in February 2026. There are no suspicious gaps or sudden drops that would suggest the car has been sitting unused for long periods, which might otherwise explain accelerated corrosion. The mileage pattern points to regular use, yet the corrosion has still worsened across multiple structural zones. A buyer should treat the corrosion history as the primary concern during any in-person inspection. The front subframe and its mounting points require close examination with a torch and probe, particularly around the prescribed areas flagged in the February 2026 test. Both front suspension arms need checking for section loss, and the rear coil spring hanger areas should be inspected for the same. Corroded rear disc back plates from 2024 may have progressed, so the condition of the rear brake assemblies and disc shields warrants verification. Surface rust on suspension components can be cosmetic, but the repeated advisories across different test dates and different locations on the vehicle suggest this is more than superficial. The braking system has drawn attention at multiple tests. Rear brake discs and inner pads were flagged as worn in October 2023 at 51,734 miles, and rear disc back plates were noted as corroded in October 2024. The February 2025 failure for tyre condition, specifically a nearside front tyre with exposed cords, indicates a lapse in basic pre-test preparation. While tyres are consumables and easily replaced, the combination of worn rear brakes and neglected tyre condition raises questions about how thoroughly the vehicle was maintained between 2023 and 2025. Any buyer should verify the current condition of all four brake discs, pads, and tyres, and check whether the rear brake calipers are binding or dragging, which could explain uneven wear patterns.
