2015 Mazda 6 2.2L Diesel · NA15 CPK

The vehicle is currently roadworthy, but the maintenance history indicates a trend of worsening structural and suspension integrity. The most recent test in April 2024 at 84,034 miles identified a slight play in the offside front lower suspension arm ball joint. This follows a failure just two months prior in February due to a serious fluid leak on the offside rear shock absorber. While the car has successfully passed its subsequent tests, the recurring nature of suspension faults suggests that components are reaching the end of their operational life. At 84,034 miles over eleven years, the Mazda 6 averages approximately 7,600 miles per year, which is consistent with typical low-intensity usage. However, the data shows a significant spike in activity between May 2022 and December 2023, where the vehicle covered nearly 9,000 miles in just nineteen months. This period of higher use, contrasted with periods of lower mileage, likely accelerated the degradation of rubber components and the progression of corrosion noted on the under metalwork. A buyer must prioritise a thorough physical inspection of the rear subframe and suspension arms, as corrosion was flagged in both 2023 and 2024. Although the tester noted the subframe corrosion was not seriously weakened in late 2023, rust on these structural members often progresses rapidly if not treated. The brake history also shows a pattern of pitted and scored discs across both 2022 and 2023, indicating that the previous owners frequently deferred routine replacement of these components. Close attention should be paid to the ball joints and shock absorbers to ensure the play identified in 2024 has been properly rectified.
