2017 Nissan Micra 1.2L Petrol · AC64 ANC

The latest MOT test on 2026-09-01 returned a pass with two advisories: both rear coil springs exhibit significant corrosion, classified under 5.3.1 (b) (i), which indicates advanced rust penetration that compromises their structural integrity and load-bearing capacity. While the vehicle has otherwise maintained a clean MOT history since this failure, the presence of these advisories suggests a pattern of wear-related issues that have not been fully addressed. The fact that the same defect was noted in both rear coil springs during the most recent test implies either a design vulnerability or consistent exposure to corrosive elements, such as prolonged standing in damp conditions or poor maintenance practices. The failure from 2024-03-08—where the near-side rear service brake was excessively binding—was a major defect, indicating a critical mechanical failure that required immediate attention. Together, these records suggest a maintenance trend that has not been fully resolved, with recurring issues tied to suspension and braking systems that warrant careful scrutiny. The recorded mileage of 19,783 miles for a 2017 Nissan Micra represents a relatively low annual usage rate of approximately 2,198 miles per year, which is unusually low for a vehicle of this age. Such low mileage often reflects periods of prolonged inactivity, particularly if the car has been stored for extended durations, which can accelerate corrosion in components like the coil springs, suspension bushes, and brake systems. The absence of higher mileage accumulation suggests that the vehicle has not undergone rigorous daily use, potentially masking deeper wear issues that might develop under heavier loads. However, low mileage alone does not absolve the vehicle of age-related wear, as standing corrosion, fluid degradation, and component fatigue can still progress silently over time. The recent advisories on the coil springs and binding brakes further underscore the importance of understanding whether the vehicle has been exposed to conditions that exacerbate these failures, such as damp storage or infrequent servicing. To proceed with a thorough inspection, the prospective buyer should prioritise checking the rear suspension components for signs of further corrosion or mechanical failure. The advisories on the coil springs indicate that rust has penetrated to the point where structural integrity is compromised, and any future movement or noise from the rear suspension during a test drive could signal imminent failure. Listen for clunks or harsh ride quality when driving over bumps, as this may reveal loose or failing suspension elements. The 2024 failure of the near-side rear service brake binding suggests that the brake calipers may be seized, causing uneven brake pad wear or a grinding noise when braking. Inspect the rear brake discs for signs of corrosion, warping, or uneven wear, and test the brake pedal for firmness and travel distance—if the pedal feels spongy or the car pulls to one side during braking, further investigation is required. Additionally, verify that the rear wheel bearings are free of excessive play or grinding noises, as these can lead to premature failure if left unaddressed. Beyond the mechanical checks, the buyer should also examine the vehicle’s overall condition for signs of prolonged standing-related issues. Inspect the undercarriage for rust around the wheel arches, exhaust system, and suspension mounts, as damp conditions can accelerate corrosion in these areas. Check the tyre tread depth and sidewall condition, as low mileage can sometimes mask wear from age-related cracking or perishing of the rubber, which becomes critical if the vehicle has been stored for extended periods. The 12V battery should be tested for charge retention and physical integrity, as prolonged inactivity can lead to sulphation or corrosion of terminals. Finally, since the vehicle is nearing its 9-year mark, the buyer should confirm that all scheduled maintenance—particularly fluid servicing (oil, brake fluid, coolant, and transmission fluid)—has been conducted according to the manufacturer’s recommendations. Given the advisories on the coil springs and binding brakes, it is prudent to arrange a pre-purchase inspection by a qualified mechanic to assess the extent of the corrosion and mechanical wear, ensuring that any necessary repairs are budgeted for before purchase.
