2016 Hyundai Tucson 1.7L Diesel · WN66 UGJ

A pattern of brake and rear suspension wear emerges as the defining mechanical theme across this Hyundai Tucson's MOT record, with the most recent test on 24 August 2026 returning a clean pass without recorded defects, but with three of the previous four tests carrying advisories concentrated on the rear axle and braking system. The 2023 test flagged both rear brake discs as pitted or scored alongside thinning rear pads, the 2024 pass was clean, and the 2025 test noted a deteriorated nearside rear brake hose plus the now-recurring offside rear seat belt webbing fraying that had first appeared in 2023. A more serious entry sits in the 2022 history: a Major failure was issued for an excessively worn shock absorber bush on the offside rear suspension, accompanied by advisories for front tyres worn to the legal limit and an oil leak that was not deemed excessive. The absence of defects on the 2026 test is a positive recent data point, but the recurring rear-end focus across multiple annual entries means a prospective buyer should not interpret the latest clean pass as evidence that the underlying wear issues have been resolved. With 121,586 miles recorded over a ten-year life, this Tucson has averaged roughly 12,159 miles per year, a notably high accumulation rate that points to sustained long-distance or commuter use rather than the lighter urban mileage typical of its age cohort. There are no extended gaps in the annual testing record that would suggest prolonged off-road storage, and the mileage progression between consecutive tests broadly tracks the annual average, indicating continuous service rather than intermittent use. Mechanically, this usage profile places greater demand on the consumables and chassis components that have already shown wear in the MOT data: the brake discs, pads, flexible hoses, and rear suspension components all deteriorate faster under higher mileage, and the oil leak flagged in 2022 warrants particular attention given that engine seals and gaskets tend to worsen progressively with continued running rather than self-correcting. The high annual mileage also raises the likelihood that other wear items not specifically tested on MOT, such as the timing chain, dual-mass flywheel on the manual variants, and turbocharger if fitted, will be closer to their service thresholds than on a lower-mileage equivalent. A physical inspection should focus squarely on the components that have appeared repeatedly in the advisories. The deteriorated nearside rear brake hose noted in 2025 should be checked visually for cracking, swelling under load, and any seepage at the unions, and a firm brake pedal application during a test drive will help reveal any sponginess or excessive travel indicative of hydraulic weakness. The rear brake discs, which were scored in 2023, should be inspected for lipping at the outer edge and measured for remaining thickness, as heavy scoring can compromise braking efficiency and lead to pedal pulsation under sustained effort. The offside rear shock absorber bush that failed in 2022 is worth particular scrutiny: with the vehicle unladen, press down firmly on each rear corner and release, listening for any clonking or knocking from the damper mounting points, and check for uneven ride height or excess body roll during cornering that would suggest the bush has worn again. The seat belt webbing fray on the offside rear should be examined directly by pulling the belt fully out and inspecting along its length for cuts, fraying, or stiffening of the weave. The oil leak noted in 2022 warrants a cold-start inspection: with the vehicle parked overnight, check the ground beneath the engine for fresh drips, then examine the sump, cam cover gasket, and any visible turbo or oil cooler lines for wet residue or staining. The front brake discs and pads flagged as worn in 2020 and 2021 should be checked for judder under medium to heavy braking, particularly from higher speeds, and for any grinding noise indicating pad material depletion. Given the high mileage, listen carefully on the test drive for any timing chain rattle on a cold start, any clonks from the front suspension over uneven surfaces, and any vibration through the steering wheel at motorway pace which could point to worn wheel bearings or balancing issues. Finally, confirm the offside rear seat belt has been physically replaced or repaired since the 2025 advisory, as frayed webbing is a failure item at the next test rather than a minor concern.
