2012 Mazda 3 1.6L Diesel · KY12 FHT

The 2012 Mazda 3 holds a valid MOT certificate issued on 1 May 2026 at 122,846 miles, passing with several minor advisories. The maintenance trend is broadly stable but reveals persistent, low-level wear across multiple test cycles rather than a clear pattern of deterioration or improvement. The most recent test flagged both rear anti-roll bar linkage ball joints for slight play, a condition present in every MOT since May 2024, alongside worn rear tyre edges, corroded rear suspension components, and defective wiper blades. These are not new failures, but their recurrence suggests the vehicle has been kept running without fully resolving known wear items. At roughly 14 years old with 122,846 miles, the annual average sits close to 8,775 miles, which is typical for its age. The mileage progression is consistent and well-documented, showing approximately 11,400 miles added between May 2024 and May 2025, then a further 11,384 miles by May 2026. There are no suspicious gaps or sudden drops in recorded distance, indicating regular use rather than long periods of inactivity. The MOT history itself is complete and consecutive, with no missing annual tests, which supports a pattern of responsible ownership from at least 2024 onward. The recurring advisories deserve closer inspection. The nearside and offside rear anti-roll bar linkage ball joints have shown slight play in every test since May 2024, meaning the joints have been monitored but not replaced across three consecutive MOT cycles. This is not an immediate failure risk, but worn linkages can progress to knocking over bumps and reduced roll stability. The rear sub-frame and suspension corrosion noted in May 2025 remains a structural concern worth probing with a torch and screwdriver during any in-person inspection, particularly around mounting points and lower arm attachment areas. The front lower suspension arm rear bushes were flagged as worn but not resulting in excessive movement in May 2025, and they did not reappear as advisories in 2026, suggesting they may have been replaced; a buyer should verify this visually. Brake wear appears to be managed reactively rather than proactively. Rear brake pads were flagged as wearing thin in April 2024, and the nearside rear tyre was noted as worn close to the legal limit in May 2026. These are consumable items, but the pattern suggests replacement intervals are being stretched rather than anticipated. The headlamp advisories have evolved from slightly defective lenses in 2024 to products on the light sources in 2026, indicating the lenses may have deteriorated further or aftermarket bulbs have been fitted. A beam pattern check on a headlamp aiming board would confirm whether output remains compliant in practice. Overall, this is a vehicle that has been kept on the road without major mechanical failure, but the accumulation of unresolved advisories points to a cost-conscious maintenance approach rather than a preventative one.
