2018 Mazda 6 2.2L Diesel · LP18 SMV

The 2018 Mazda 6 presents a stable and improving maintenance trend, culminating in a notably clean bill of health at its most recent MOT on 22 May 2026 at 78,617 miles, where the tester recorded zero advisories or defects. This marks a significant turnaround from the preceding four consecutive annual tests, all of which flagged at least one item. The vehicle's roadworthiness status is currently excellent on paper, suggesting the previous owner addressed the longstanding issues comprehensively in the last twelve months. The mileage accumulation is consistent and unremarkable for an eight-year-old vehicle. Between the June 2022 test at 48,567 miles and the May 2026 test at 78,617 miles, the car covered approximately 30,050 miles over nearly four years, averaging around 7,500 miles annually during that window. This sits slightly below the overall lifetime average of roughly 9,827 miles per year, indicating the car may have been used less intensively in recent years or potentially stood for extended periods. No anomalous gaps or sudden spikes in the odometer record suggest the mileage history is credible. Despite the clean 2026 result, the recurring rear brake disc wear documented in four consecutive tests from May 2023 through May 2025 deserves attention. The tester repeatedly noted discs worn, pitted, or scored but not seriously weakened, a pattern that suggests the rear braking system endured prolonged stress without prompt disc replacement. A prospective buyer should inspect the rear brake discs and calipers in person for uneven wear, lipping, or binding, and check whether the recent MOT's clean result reflects genuine repair or simply a fresh set of pads masking underlying disc deterioration. The front brake pads were flagged as wearing thin in May 2023, so verify the condition of the entire braking system, including lines and fluid. The tyre-related advisories from 2024, including a kerb-damaged nearside front sidewall and edge wear on both front tyres, point to possible alignment or suspension geometry issues, though these did not recur in subsequent tests. Inspect the inner sidewalls and tread patterns of all four tyres for uneven wear, and check the condition of suspension bushes, track rod ends, and coil springs. Given the absence of any structural corrosion or emissions defects throughout the entire MOT history, the vehicle appears to have been kept in reasonable mechanical order, but the repeated brake advisories warrant a thorough on-inspection verification of the rear axle braking components.
