2014 Mazda 6 2.2L Diesel · TW51 DWW

The vehicle remains roadworthy, but the maintenance trend shows a shift from minor wear to developing corrosion issues. The most recent test in June 2025 at 63,900 miles identified corrosion on all four outer brake pipes, which were also covered in grease. This represents a significant departure from the clean records of 2023 and 2024, suggesting that while the car passed, the hydraulic lines are now beginning to degrade and require attention. The mileage profile is consistently low for a twelve-year-old vehicle, averaging approximately 5,325 miles per year. The data shows a steady progression, moving from 44,647 miles in 2021 to 63,900 miles in 2025. This low usage often means less mechanical strain on the engine and drivetrain, but it frequently correlates with the accelerated aging of rubber components, as seen with the perishing suspension ball joint gaiters noted between 2021 and 2022. A buyer must conduct a thorough physical inspection of the braking system to ensure the corrosion noted in 2025 has not progressed to structural thinning of the pipes. The history of pitted and scored front brake discs in 2022 indicates the braking components may be prone to surface rust during periods of standing. The suspension arm ball joints and their gaiters should be checked for tears or play, as recurring flags in these areas suggest the rubber seals are reaching the end of their service life due to age rather than distance.
