2009 Mazda 3 1.6L Petrol · PE09 HXM

The vehicle is currently roadworthy but exhibits a clear trend of worsening structural corrosion and mechanical wear. While it passed its most recent test in March 2026 at 148,206 miles, the record reveals a significant increase in advisories compared to previous years. The appearance of corroded fuel pipes and rear sub-frame corrosion in the latest test indicates that the underlying oxidation issues are actively progressing. The previous failure in January 2025 for a fractured coil spring and failing ball joint suggests that maintenance follows a reactive rather than preventative pattern. At 148,206 miles, the car has followed a consistent usage pattern of approximately 8,700 miles per year, which is typical for a seventeen-year-old vehicle. The data shows regular annual testing intervals, with a 13,000-mile gap between January 2024 and January 2025, and another 11,000 miles between January 2025 and March 2026. This steady mileage suggests the vehicle is not sat for long periods, which explains the gradual degradation of rubber components and metal surfaces. A buyer must prioritize a thorough underbody inspection focusing on the rear sub-frame and brake lines. The tester repeatedly flagged corrosion in the sub-frame mounting areas since 2024, and the recent addition of corroded fuel pipes suggests the structural integrity of the chassis components is at risk. The offside front drive shaft CV boot has been noted as severely deteriorated since 2023, indicating it has never been replaced and will likely lead to imminent joint failure. Additionally, the rear brake discs are now pitted and scored, and the persistent misting on the nearside rear shock absorber indicates it is nearing the end of its life.
