2016 Mazda 3 2.0L Petrol · LO66 DLX

The most recent MOT, dated 20 November 2025, was passed but carried an advisory that the rear brake pads were wearing thin. Earlier in the series, the 23 November 2022 test also passed with an advisory noting corrosion on both rear coil springs. Apart from these two advisories, the vehicle has consistently cleared MOT without recorded defects over the past seven years, indicating a generally stable maintenance record with only the expected progression of wear items. At 100 651 miles the Mazda 3 averages just over 10 000 miles per annum, which is typical for a ten‑year‑old family hatchback. The mileage does not suggest any periods of prolonged inactivity that might have led to standing‑time deterioration, nor does it reveal any unusually high annual run‑off that would accelerate component fatigue. Consequently the wear on consumables such as tyres, brakes and suspension elements should be proportionate to age and mileage rather than excessive mileage spikes. When you inspect the car, pay particular attention to the rear suspension. Corroded coil springs can become brittle and may develop cracks, leading to a loss of ride height or a noisy, uneven rear ride. Check the rear shock absorbers for oil leakage and feel for any clunking when compressing the rear corner over a bump. The thin rear brake pads flagged in the latest MOT suggest that the pads may need replacement soon; listen for any squeal or feel for a slight increase in stopping distance, especially under repeated braking. Examine the brake discs for scoring or excessive rust, as uneven pad wear can cause premature disc wear. Verify that the front brakes are in good condition, as rear pad wear often coincides with front pad thickness that should still be within safe limits. Given the vehicle’s age, also inspect the tyre sidewalls for cracking, dry rot or age‑related hardening, even if the tread depth appears adequate. Test the 12‑volt battery with a load tester or have it checked for voltage drop, as a ten‑year‑old battery may be nearing the end of its service life. Examine all fluid reservoirs – engine oil, coolant, brake fluid and power‑steering fluid – for correct levels, colour and any signs of contamination; fluids typically require replacement on a calendar basis regardless of mileage. Finally, look for any signs of corrosion on the chassis, especially around the rear suspension mounting points, and ensure that the service history is documented with regular oil changes and filter replacements to confirm that the engine has been well cared for.
