2021 Mazda 3 2.0L Petrol · LS21 YBL

The vehicle is currently roadworthy but the maintenance history shows a worsening trend regarding corrosion-related component degradation. While it passed its most recent test in February 2026 at 39,234 miles, the tester identified corrosion on both rear suspension shock absorber mounts and the rear fuel pipes. This represents a progression from the March 2025 test where only coil springs were flagged for corrosion, suggesting that the vehicle is susceptible to environmental rust despite its relatively low mileage. The mileage pattern is consistent with a five-year-old vehicle, averaging approximately 7,850 miles per year. There is a clear gap of over 9,000 miles between the March 2024 and March 2025 tests, which indicates regular usage. The failure in March 2024 at 26,745 miles was due to a structural bulge in the nearside front tyre, a safety-critical defect that was resolved immediately. This incident appears isolated, though it suggests a lack of proactive pre-test checks by the owner. A buyer must conduct a thorough physical inspection of the underbody to assess the extent of the rust. The recurring issues with rear coil springs, shock absorbers, and fuel pipes indicate that the vehicle may have operated in a high-corrosion environment or region. Particular attention should be paid to the brake discs, as the 2025 record noted the front discs were pitted and scored. The corrosion on the rear fuel pipes mentioned in the latest test needs to be visually verified to ensure it has not progressed to a point of thinning that could lead to a leak in the near future.
