2009 Mazda 6 1.8L Petrol · SH59 WLC

The vehicle’s most recent MOT test on 2025-01-17 at 73,516 miles passed without defects, but the preceding test on 2025-01-13 at 73,514 miles—just four days earlier—failed for an unspecified reason, despite no recorded defects on either occasion. This anomaly suggests either a rare administrative error or a minor, non-recurring issue that was rectified between tests. Beyond this, the 2023 and 2022 tests show consistent passes with no advisories or faults, indicating no clear pattern of recurring mechanical failures. However, the abrupt failure followed by immediate re-passage warrants scrutiny of components prone to sudden degradation, such as brake calipers, suspension bushes, or electrical systems that might trigger intermittent test failures. The recorded mileage of 73,516 miles over 17 years equates to approximately 4,324 miles annually, which is unusually low for a vehicle of this age and class. The gap between the 2022 and 2023 tests—spanning roughly 12 months—shows no significant mileage accumulation, suggesting prolonged periods of inactivity. The 2025 tests occurred within days of each other, with negligible mileage change, which may indicate the vehicle was stationary or lightly used during that period. While low mileage generally correlates with reduced wear, the lack of intermediate mileage data makes it impossible to confirm whether critical components like suspension or drivetrain were subject to prolonged stress from occasional heavy use. Given the sparse fault history, the primary focus for an in-person inspection should centre on components that often fail intermittently or degrade silently over time. The abrupt 2025 failure—despite no recorded defects—suggests potential issues with brake binding, suspension play, or electrical faults (e.g., ABS or traction control sensors). Inspect the rear brakes for uneven wear or seized calipers, as the tester did not flag any defects in prior tests. Check suspension bushes and coil springs for excessive wear or corrosion, particularly around the wheel arches and subframe mounts, where rust can compromise structural integrity. The lack of advisories does not preclude hidden corrosion, so examine the underbody for pitting or section loss, especially near the sills and wheel housings. Finally, verify the exhaust system for leaks or excessive rust, as emissions-related failures are common in older vehicles with inconsistent maintenance.
