2010 Mazda 3 1.6L Petrol · HD59 BWU

This 2010 Mazda 3 presents a stable and broadly improving mechanical picture at its most recent MOT. The March 2026 pass at 82,404 miles shows the vehicle is currently roadworthy, with only minor advisories for front brake disc wear and light lens hazing. Comparing this to the preceding 2025 test cycle, the trend is clearly positive. The 2025 failure flagged an engine MIL malfunction, a structurally torn offside rear tyre, and corroded front inner discs. All of these more serious issues appear to have been addressed before the March 2026 retest, indicating the previous owner invested in necessary repairs rather than simply patching the car for a pass. The mileage profile is notably low for a 16-year-old vehicle. The record shows 77,115 miles in March 2024 and 82,404 miles in March 2026, representing roughly 2,645 miles per year over that final two-year window. Annualised across its full life, the total of approximately 5,150 miles per year confirms very light use. This low mileage suggests reduced wear on drivetrain and suspension components, but it also raises the possibility of extended periods standing still, which can cause brake disc corrosion, tyre flat-spotting, and dried-out rubber seals. The gap between the 2024 and 2026 tests covers a full two-year interval rather than the standard annual cycle, so there is a missing year of data that a buyer should account for. The recurring brake disc advisories deserve attention. Front inner discs were flagged as corroded in March 2025 and worn or pitted in March 2026, suggesting the vehicle may sit for long periods allowing surface corrosion to develop. A hands-on inspection should verify the condition of both front and rear disc faces, pad thickness, and caliper slider operation to rule out binding. The 2025 failure for a torn offside rear tyre caused by structural separation is a concern, as it implies either a manufacturing defect or impact damage. Check all four tyres for age-related sidewall cracking, uneven tread damage, and date codes, particularly if the same wheel was not replaced. The inoperative engine MIL lamp that appeared in both the 2024 and 2025 failures but cleared by 2026 could indicate a fault was repaired or that diagnostic codes were cleared without proper rectification. A pre-purchase OBD scan is advisable to confirm no stored or pending fault codes. Structurally, the 2024 failure noted full underbody covers were fitted at the time of test, which can mask corrosion on subframes, sills, and suspension mounting points. A buyer should arrange an inspection with the covers removed, paying close attention to the rear suspension areas and brake pipe runs. The defective nearside rear reflector flagged in 2024 and the seat belt buckle fault from the same test both appear to have been resolved, but verifying seat belt retraction and buckle engagement across all positions remains a sensible precaution. Overall, the vehicle shows evidence of corrective maintenance, but the combination of low annual mileage, underbody covers, and recurring brake advisories warrants a thorough physical inspection before purchase.
