2016 Mazda 3 2.0L Petrol · SA16 AAL

The vehicle most recently passed its MOT on 6 March 2026, with a single advisory recorded for slight damage to the outer sidewall of the nearside rear tyre. While the current pass is reassuring, a review of the preceding test history reveals a maintenance trend that warrants careful attention. The 2025 test cycle demonstrates volatility, as a major failure was recorded on 22 August 2025 due to a fractured nearside rear coil spring, followed by a clean pass just six days later. Earlier, in September 2024, the vehicle failed its MOT with a dangerous defect concerning a nearside front tyre bulge caused by structural separation, alongside advisories for corroded front brake pipes and worn, pitted front brake discs. This pattern of escalating suspension and brake component deterioration, though partially addressed, suggests that the underlying wear profile of the vehicle has not been entirely stabilised. With 73,965 miles recorded over a ten-year lifespan, the vehicle averages approximately 7,396 miles annually, which is broadly consistent with typical usage for a car of this age. This moderate annual mileage generally suggests a balanced wear pattern across consumable components, although the clustering of test failures and advisories within the last twenty-four months indicates that wear is advancing in specific areas. The fact that major and dangerous defects were identified relatively close together suggests that the suspension, braking, and tyre systems are reaching a stage where proactive replacement rather than reactive repair is becoming necessary. For a prospective buyer, a thorough physical inspection and test drive should focus on the areas previously flagged. Given the recent fractured coil spring failure, listen carefully for any clonking or knocking noises from the rear suspension over uneven surfaces, and check for uneven rear tyre wear which can indicate compromised geometry from a weakened spring. Inspect the nearside front tyre carefully for any remaining bulging or sidewall deformation, and examine the sidewalls of all tyres for perishing or cracking given the vehicle's age. The advisories regarding corroded brake pipes and pitted front brake discs warrant particular scrutiny; during a test drive, any pulsation through the brake pedal, shudder under heavy braking, or pulling to one side would suggest the discs have deteriorated beyond the advisory stage. The front brake system should be visually inspected for any seepage at pipe unions and the condition of the flexible hoses, as further corrosion could lead to fluid leaks and compromised stopping performance. Additionally, age-related maintenance should be verified regardless of the recorded mileage, as calendar-based degradation affects this vehicle as much as wear from use. Confirm the service history documentation to ensure timing belt or chain replacement intervals, spark plug changes, and coolant and brake fluid renewal have been completed according to schedule, as brake fluid is particularly susceptible to moisture absorption over time. The air conditioning compressor and drive belts should be checked for age-related cracking. Inspect the underside and wheel arches for any advanced corrosion, paying close attention to suspension mounting points and subframe integrity, as standing moisture and road salt can accelerate structural degradation. Finally, test all electrical functions including the infotainment system, reversing camera, and parking sensors, and verify the 12V battery health, as original units on a ten-year-old vehicle are often approaching the end of their reliable service life.
