2018 Nissan Qashqai 1.5L Diesel · DS18 NKM

This Qashqai has demonstrated a concerning pattern of mechanical neglect over the past two years, culminating in a major failure just ten days ago. The most recent MOT on 2026-08-04 passed without defects, but the failure on 2026-07-17 for an excessively worn offside front suspension arm pin or bush—paired with a loose rear exhaust heat shield advisory—signals a vehicle that has been driven with critical components at or beyond their serviceable limits. The recurrence of front brake advisories (worn discs and thin pads) in both 2025 and 2026 suggests these have been deferred rather than addressed, while the near-front tyre advisory in 2024 implies basic upkeep was inconsistent. The trend is unambiguously worsening, with structural suspension components now at risk of catastrophic failure. The mileage progression of 71,485 miles over eight years averages approximately 8,936 miles annually, which is typical for a vehicle of this age. However, the MOT history reveals significant gaps in maintenance documentation. Between the 2024 and 2025 tests, the vehicle accumulated 17,000 miles without any recorded advisories or failures, yet the front brakes and tyres were already showing advanced wear by 2025. This suggests either sporadic servicing or a lack of owner awareness, as critical components were clearly past their recommended service intervals. The most recent 6,000 miles between tests (July 2026 failure and August 2026 pass) were driven with a known major suspension defect, which is unacceptable. A prospective buyer should prioritise an immediate and thorough inspection of the front suspension, particularly the offside arm pin and bush, as this failure mode can lead to sudden handling instability or steering misalignment. The rear suspension should also be scrutinised for signs of wear or corrosion, given the loose exhaust heat shield advisory—this could indicate broader structural fatigue. Front brake discs and pads must be measured for remaining thickness, as the advisories in consecutive tests imply they have been run beyond safe limits. Additionally, the tyres should be checked for uneven wear or edge damage, which could correlate with suspension issues. Rust around wheel arches, subframes, and the exhaust system should be inspected, as the loose heat shield may precede more serious corrosion-related failures. Given the history, a pre-purchase diagnostic from a reputable garage is essential to confirm the suspension and brakes are not in a deteriorating state.
