2015 Mazda 3 2.0L Petrol · FV64 POA

The 2015 Mazda 3 presents a mixed maintenance picture. The most recent MOT on 5 September 2025 at 63,468 miles passed, but the tester flagged a slightly damaged nearside rear tyre outer wall and an offside rear service brake binding. These are minor, yet the binding caliper warrants attention. The trend is not clearly improving. A failure on 28 August 2024 at 55,663 miles for excessive nearside front wheel bearing play and corroded brake pipes was followed by a pass on 5 September 2024 at 55,831 miles after repairs. However, the underlying corrosion theme persists. Rear coil spring corrosion appeared in 2022 and again in 2024, suggesting the vehicle may have been stored or used in conditions promoting underbody damp. The parking brake efficiency only just met the standard in 2024, indicating the braking system has been a recurring weak point rather than a resolved one. The mileage profile is notably low. At roughly 5,770 miles per year, the car has covered just 63,468 miles over eleven years. The record shows a jump from 51,557 miles in August 2023 to 55,663 miles in August 2024, a gain of 4,106 miles in one year, then a further 7,637 miles to the September 2025 test. This suggests a change in usage pattern, possibly from a second car to a more regular commuter. The gap between the 2024 failure and the 2025 pass is only nine months, yet the mileage increased by 7,637 miles, confirming heavier recent use. Low annual mileage can mask long periods of inactivity, which often accelerates rubber perishing and brake corrosion. A buyer should focus on the underbody and braking components. The repeated advisories for corroded upper brake pipes, covered in grease or other material, point to surface corrosion that may have worsened since the last test. Inspect all flexible and rigid brake lines for pitting, especially at mounting points. The rear coil spring corrosion flagged in 2022 and 2024 remains a structural concern; check for cracking or reduced spring height. The nearside front wheel bearing failed with excessive play in 2024 and was presumably replaced, but verify for any residual roughness on a lift. The binding offside rear caliper in 2025 suggests a sticking piston or slide mechanism; test for uneven pad wear and overheating. The rear tyre damage on the outer wall is a cut or impact risk, not simple age perishing, so examine the sidewall closely for bulges. Beyond the flagged items, assess the exhaust for corrosion given the age, and check the condition of all suspension bushes and anti-roll bar links, which can perish on a car that has stood for long periods. The parking brake performance in 2024 was marginal, so test the handbrake on a steep incline and inspect the rear cables for free movement. The MOT record shows a car that has had intermittent attention rather than consistent preventative care. A thorough pre-purchase inspection, with emphasis on brake hydraulics and suspension corrosion, is strongly advised.
