2015 Mazda 6 2.2L Diesel · DA65 HTN

The Mazda 6 presents as roadworthy following its most recent pass on 13 February 2026 at 77,682 miles with no defects recorded. The maintenance trend is stable across the three years of available history, with every pass showing a clean sheet and no advisories on suspension bushes, brake discs, corrosion, or exhaust emissions. The only blemish is a pair of immediate fail-then-pass cycles in early 2025 and early 2026, both at identical mileages to their subsequent passes and with no defects logged by the tester. Annual mileage sits at roughly 7,062 miles per year against an 11-year-old car, which is typical for the age. The record shows steady accumulation: 68,987 miles in February 2024, 73,005 in February 2025, and 77,682 by February 2026. That is about 4,000 to 4,700 miles added each year with no sudden jumps or long dormant periods. The data is sparse but clean, offering no evidence of neglected consumables or deferred mechanical work. The February 2025 fail at 73,005 miles and the February 2026 fail at 77,526 miles are anomalous. DVSA logs show no defects recorded on either failure, yet both were followed within days by a pass at the same mileage. This pattern suggests administrative or documentation issues at the testing station rather than a mechanical fault on the vehicle. A buyer should still verify the V5C and MOT test certificate numbers with DVSA to confirm the failures were not suppressed defects. In person, the buyer should confirm structural integrity around chassis and subframes, check coil springs and suspension arms for fatigue, and inspect brake calipers for binding given the unexplained fails. The clean advisory history means no recurring wear trend exists, but a pre-purchase inspection remains sensible on an 11-year-old vehicle with unknown owner care habits.
