2015 Mazda 6 2.2L Diesel · ND65 CZZ

The vehicle is currently rated as roadworthy, but the MOT history indicates a concerning trend of instability rather than stability. The most recent test on 2025-12-01 at 68,190 miles was passed, yet this is a significant gap from the 2024-11-01 test at 54,487 miles, where the vehicle failed. This discrepancy suggests the owner may have been in a state of disuse or neglect between the two tests, allowing wear on critical components to accumulate. The 2024-10-31 failure on 54,487 miles confirms that the vehicle has not maintained its mechanical integrity since the previous year, indicating a lack of consistent upkeep. Regarding the mileage pattern, the data is sparse and clean, with no gaps in the record that would suggest a rapid accumulation of wear. The vehicle has maintained roughly 6,199 miles per year since its last test in 2024, which is consistent with typical usage for a 2015 model. However, the absence of a gap between the 2024-11-01 and 2024-10-31 tests, followed by a failure in 2024, implies that the owner has not been actively driving the car or replacing wear items. This pattern suggests that the vehicle has likely been sitting in a garage for some time, which is a major risk factor for structural integrity. In conclusion, the 2015 MAZDA 6 is roadworthy but carries a high risk of sudden failure due to the lack of maintenance history. The most recent test was passed, but the gap between it and the previous failure in 2024 indicates a potential structural issue. The vehicle should be inspected immediately for binding rear brakes, exhaust heatshield integrity, and suspension bushings, as these components are the most likely candidates for failure given the history. A buyer must be prepared for a potential recall or need to replace these parts before the vehicle reaches the next MOT.
