2017 Mazda 3 2.2L Diesel · LP17 NME

A pattern of escalating mechanical failures in the braking and suspension systems defines this vehicle's recent inspection history. While the car passed its most recent test on 28 January 2026, this followed a failed inspection just one week prior that identified a dangerous defect regarding a seriously weakened rear brake disc, a major failure on the offside rear shock absorber due to a serious fluid leak, and misaligned windscreen washer jets. This recent volatility contrasts with a period of clean passes between 2020 and 2022, suggesting that the vehicle's components are currently entering a phase of significant wear and potential component fatigue. The recorded mileage of 111,516 miles indicates a high rate of usage for a nine-year-old vehicle, averaging approximately 12,391 miles per year. This consistent, higher-than-average annual accumulation typically accelerates the degradation of wear-and-tear items. In this specific case, the mileage correlates with the documented deterioration of the braking system and suspension components, as the increased mechanical load and thermal cycles associated with higher mileage often lead to the thinning of brake pads, the pitting of discs, and the eventual failure of hydraulic seals within shock absorbers. Prospective buyers should pay close attention to the braking system and rear suspension during a test drive. Given the recent dangerous failure of the rear brake disc and previous advisories regarding worn and pitted discs, it is essential to check for any pedal judder, vibration through the brake pedal, or unusual grinding noises when applying the brakes. The recent failure of the offside rear shock absorber due to a fluid leak necessitates a physical inspection for oil residue on the component itself. On the road, listen for any knocking or thudding sounds from the rear of the vehicle when driving over uneven surfaces or speed bumps, which could indicate further suspension instability or worn bushes. Further inspection of the electrical and fluid delivery systems is also warranted. The history of failed direction indicators and misaligned washer jets suggests that while these are often simple fixes, they are part of a recent trend of multiple defects appearing in single tests. Ensure all indicators are functioning correctly and that the windscreen washer system provides a consistent, directed spray. The transition from advisories for worn brakes in late 2023 to dangerous failures in 2025 and 2026 highlights a rapid progression of component wear that requires thorough verification of the current state of the entire braking assembly.
