2017 Mazda 6 2.2L Diesel · LR67 AYT

The most recent MOT test on 2025-06-24 confirms this Mazda 6 remains roadworthy with no defects recorded at 92,420 miles, but the history reveals a critical anomaly: a duplicate entry for July 2023, where the vehicle was both passed and failed at the same mileage (82,774). This suggests either an administrative error or a deliberate attempt to bypass testing, which raises immediate concerns about the vehicle’s true condition. Beyond that, the consistent pass rates—with no advisories or defects—indicate the tester did not identify any recurring mechanical issues over the past four tests. However, the lack of advisories in recent years does not preclude hidden wear; the clean record may reflect either diligent maintenance or a vehicle that has not yet reached the threshold for visible failures. The mileage progression shows steady accumulation, averaging roughly 10,269 miles annually, which aligns with typical usage for a vehicle of this age. There are no prolonged gaps or abrupt jumps in mileage that would suggest neglect or excessive wear, though the 2023 duplicate test date—just three days after the previous pass—stands out as unusual. The most recent test was conducted just over a year ago, which is within the standard 12-month MOT validity period, though buyers should verify if the vehicle has been driven extensively since then. The absence of advisories in the 2024 and 2025 tests suggests no major components were approaching failure, but this does not rule out gradual degradation in areas like suspension bushes, coil springs, or brake caliper binding, which often develop without immediate test failures. Given the lack of recorded defects, a buyer should prioritise a thorough inspection of the suspension system, particularly the rear bushes and coil springs, as these components frequently fail without triggering MOT advisories. The brakes, while not flagged in tests, should be checked for uneven wear, binding calipers, or corrosion on the rear discs—common issues on this model that can escalate into safety risks. Structural integrity is another concern; the underbody, wheel arches, and sills should be examined for corrosion, especially around the rear axle and wheel housings, where rust can compromise the chassis. Finally, the exhaust system warrants attention, as catalytic converter failures or leaks often go unnoticed until emissions tests or drivability issues arise. The clean MOT history does not guarantee these areas are sound, but it does suggest the vehicle has not yet exhibited obvious failures in these critical zones.
