2015 Mazda 2 1.5L Petrol · ST15 PTX

The vehicle is currently roadworthy but the maintenance history reveals a worsening trend regarding structural integrity and corrosion. While it passed the most recent test on June 2026 at 102,169 miles, the tester identified corrosion on both rear brake pipes and the rear suspension component mounting area. This represents a progression from the front brake pipe corrosion noted in 2022, suggesting that the vehicle's underbody is subject to active oxidation despite previous repairs. The mileage pattern is consistent with a typical-use vehicle, averaging approximately 9,300 miles per year. There is a notable gap in the records between November 2022 and November 2023, during which the car covered 20,037 miles. This high-intensity period coincided with a significant structural failure at 93,217 miles. Although the annual mileage remains standard for an eleven-year-old Mazda, the density of use during that period likely accelerated the degradation of the chassis. A buyer must conduct a thorough physical inspection of the lower sills and structural mounting points. The 2023 failure for holed outer sills with reduced structural rigidity is a serious concern that indicates deep-seated rust. Even if these areas were repaired, the recurring presence of corrosion on the brake lines and suspension mounts in 2026 suggests the protective coatings are failing globally. You should verify the quality of the previous structural repairs and check for fresh welding or bubbling paint around the wheel arches to ensure the corrosion is not returning.
