2015 Mazda 3 2.0L Petrol · SW15 HUU

The vehicle is currently roadworthy, though the maintenance trend indicates a shift toward age-related component degradation. Following the most recent test in September 2025 at 45,117 miles, the tester identified corrosion on both rear lower suspension arms and both rear anti-roll bar drop links. While these issues were not classified as seriously weakened at the time, they represent the start of structural integrity beginning to fail, marking a departure from the clean records seen in the preceding years. The mileage profile is notably low for an eleven-year-old vehicle, averaging approximately 4,100 miles per year. This low usage suggests the car has faced minimal strain on drivetrain and engine components, but the data reveals significant gaps in testing intervals. Between December 2022 and November 2023, the car covered only 1,665 miles over nearly a year. Such low mileage often correlates with the drying of rubber components and the onset of corrosion, which aligns with the failure of the nearside rear coil spring in November 2023. A buyer must prioritise a thorough inspection of the rear suspension geometry to assess the extent of the corrosion flagged last year. The fractured coil spring noted at 40,692 miles indicates the suspension components may be prone to stress or environmental fatigue despite the low mileage. Specific attention should be paid to the lower suspension arms and anti-roll bar linkages to ensure the corrosion has not progressed from surface rust to structural thinning. Given the vehicle's age and infrequent use, checking for brake seizing and perished seals is essential, as these components suffer when a car sits stationary for extended periods.
