2018 Nissan Qashqai 1.5L Diesel · DS18 MLL

A pattern of recurring advisories on the suspension, braking and underbody components, combined with two separate test failures during the recorded history, defines the mechanical profile of this 2018 Nissan Qashqai. The most recent test on 27 August 2026 returned a clean pass with no advisories, which interrupts an otherwise accumulating list of wear-related flags. Across seven recorded tests since 2022, there are two failures, including a 2024 failed result for an inoperative or malfunctioning engine management indicator lamp and a 2023 failed test for a significantly worn front brake disc and a dangerous nearside front tyre below the 1.6mm tread threshold. The advisories have clustered around the front and rear suspension bushes, the rear brake discs, and the offside rear shock absorber casing, which together point to a vehicle that is developing the sort of wear expected on a platform of this age even at modest mileages. The overall trend is not deteriorating sharply, but neither is it stable, and the density of advisories on the same components in consecutive tests warrants attention. The recorded mileage of 45,561 miles over roughly eight years equates to an average annual accumulation of around 5,695 miles, which is below typical for a family crossover of this vintage. The gap between the 2023 and 2024 tests is short, but there is no obvious multi-year lay-up in the recorded history, suggesting the vehicle has been in regular but light use rather than long-term storage. Low annual mileage reduces wear on high-cycle items such as the clutch, engine internals and gearbox, but it can also accelerate corrosion on unprotected underbody components and standing deterioration of brake discs through infrequent use, particularly in damp conditions. The advisory on the rear brake disc being pitted or scored and the offside rear shock absorber casing corrosion both align with this slower-use pattern rather than high-mileage wear, and the suspension bush advisories are also consistent with light, urban-style accumulation. For a prospective buyer, the immediate priority on inspection should be a careful assessment of the front suspension. The 2024 advisories flagged both front suspension arm rear bushes with wear not yet resulting in excessive movement, and these should be re-checked on a test drive by listening for clonks or knocking noises from the front end over uneven surfaces, speed humps and during full-lock manoeuvres. Any progression to measurable play would now warrant replacement, and a bouncing or unsettled ride after bumps could indicate that the bushes have worn further. The rear brake disc condition flagged in 2025 should also be physically inspected via the wheels if possible, looking for a pronounced lip on the disc edge, surface scoring visible through the caliper aperture, and any uneven braking feel or pedal pulsation under moderate deceleration, which would suggest disc runout or thickness variation. The corroded offside rear shock absorber casing recorded as an advisory should be examined for any fluid seepage, deterioration of the upper mount, or a loose knocking noise from the rear over undulations, as corrosion on the casing can progress to the seal area and compromise damping performance. The engine management MIL failure from January 2024, although rectified at the same test, should be investigated before purchase to confirm the underlying fault has been properly resolved rather than simply having the lamp reset. A live diagnostic read-out is advisable to confirm no stored or pending fault codes related to emissions, sensors or the catalytic system, as intermittent MIL issues on Qashqai models are commonly linked to lambda sensors, evaporative system leaks, or ignition-related faults. The 2023 dangerous tyre failure and front brake disc advisories indicate that braking and tyre condition have been intermittent concerns, so a thorough walkaround of all four tyres for age cracking, sidewall damage, and minimum tread across the full tread width is essential, alongside a check that the front brake discs have been renewed or skimmed rather than left heavily scored. Taken together, the history suggests a vehicle that is fundamentally roadworthy but approaching the stage where proactive attention to the suspension and braking hardware would be prudent, and a pre-purchase inspection with the vehicle on a lift would be strongly advisable to confirm the underbody and bush condition independently of the MOT advisories.
