2008 Mazda 3 2.0L Petrol · FN58 TYA

The most recent MOT, dated 26 February 2025, was passed but recorded an advisory for a slightly damaged or perishing nearside rear tyre. The preceding test, just one day earlier, failed on several counts – a dangerous rear brake‑pad thickness of less than 1.5 mm, a major defect on the off‑side front suspension arm ball‑joint, and an inoperative rear registration‑plate lamp – together with advisories for the same tyre condition. Earlier MOTs show a pattern of recurring corrosion advisories on coil springs, anti‑roll bars and rear suspension arms, interspersed with occasional failures. Overall the maintenance trend is worsening, with age‑related corrosion persisting and critical wear now appearing on the brake pads and front suspension, indicating that remedial work has not kept pace with the vehicle’s deterioration. At 91 990 miles the car averages roughly 5 100 miles per year over its 18‑year life, which is well below the typical usage for a Mazda 3 of this age. Such low annual mileage often points to long periods of inactivity or very light use, conditions that accelerate component perishing and corrosion rather than mechanical wear from high mileage. The limited mileage reduces the likelihood of engine or transmission wear, but the extended idle periods can promote brake‑pad glazing, tyre sidewall cracking, battery sulphation and rust on suspension linkages, all of which are reflected in the MOT record. A prospective buyer should give particular attention to the rear braking system. Verify that the nearside rear brake disc is free of deep scoring and that the pads have been replaced to a safe thickness; on a test drive feel for any pulsation, squeal or reduced braking efficiency, especially when applying the rear brake. Inspect the off‑side front suspension arm ball‑joint for any play by checking for clunking when the wheel is rocked vertically and laterally, and ensure the rear registration‑plate lamp operates correctly. The tyre flagged as perishing should be examined for sidewall cracks, tread separation and uneven wear, and a replacement may be prudent if any signs of age‑related degradation are evident. Given the vehicle’s age and low mileage, a thorough visual and tactile inspection of all suspension components is essential – look for surface rust on coil springs, anti‑roll bars and rear arms, and feel for any looseness in bushings or mounts. Test the 12‑volt battery’s voltage and load, as prolonged storage can reduce capacity. Check the condition of all fluids – coolant, brake fluid, gearbox oil and power‑steering fluid – and confirm that they have been changed within the recommended intervals, since fluid degradation can occur even without mileage. Finally, request a complete service book to verify that any major items flagged by the MOT, such as the brake pads, suspension ball‑joint and tyre, have been addressed, and to ensure that regular servicing has been maintained throughout the car’s life.
