The defining mechanical story of this 2004 Nissan X-Trail is a progressive deterioration of its underbody and front suspension geometry, culminating in a serious structural defect on the most recent recorded examination. On 13 December 2018, the vehicle failed its MOT with a Dangerous defect for corroded rear subframe mounting, alongside Major defects for a worn offside front track rod end ball joint, a worn nearside front suspension arm ball joint, and a deeply cut offside rear tyre, while a separate pass entry on the same date noted a fractured but still rigid integral body structure. This is not an isolated incident; the October 2018 test produced a Major failure for an offside rear subframe corroded and seriously weakened, with advisories already flagging rear subframe corrosion. Across the 2015 to 2017 tests, the pattern consistently pointed toward worsening front suspension components, with repeated advisories on both sides for track rod ends, drag link ends, suspension arm ball joints, and anti-roll bar linkages, alongside thin front brake pads in 2017. The trajectory is one of escalating wear and corrosion rather than stable roadworthiness.
Mileage stands at 135,613 over approximately 22 years, equating to around 6,164 miles per year, which is broadly typical for the age but reveals meaningful usage characteristics when viewed against the test record. There are noticeable gaps in the recorded history, with tests concentrated in the autumn months of 2014 through 2018 and no recorded examinations between the end of 2018 and the present day. For a vehicle of this age and mileage, multi-year periods without recorded testing often indicate either SORN registration or operation outside the MOT requirement window, and combined with the visible corrosion at the subframe and structural areas, this raises the likelihood that age-related deterioration has continued unchecked beneath the vehicle. The mileage accumulation suggests steady but unremarkable use, and the wear evidenced in the test record is consistent with both that mileage and the passage of time on exposed chassis components.
A prospective buyer should treat the rear subframe and front suspension as the primary areas of concern during any physical inspection. The 2018 tests flagged corrosion to the extent that structural rigidity and vehicle control were compromised, so a thorough examination underneath the car is essential, ideally with the vehicle raised, paying particular attention to the rear subframe mounting points, the offside rear subframe itself, and the integral body structure noted as fractured. Any visible flaking, perforations, or previous welding repairs in these areas would be a serious concern. The front suspension should be checked methodically for play in the track rod ends, inner drag link ends, lower suspension arm ball joints, and anti-roll bar linkages, as advisories on these items appeared across multiple consecutive years before escalating to Major failures; on a test drive, listen for clonking or knocking noises over bumps, particularly from the front end, and feel for any vagueness or wandering in the steering.
Braking and tyre condition also warrant direct attention given the recorded history. The 2017 advisory on offside front brake pad wear suggests the braking system has continued to consume friction material, and a test drive should include several firm stops from speed to check for pedal judder, pulling to one side, or any grinding sensations that could indicate warped discs or seized caliper slides, both common on higher-mileage X-Trails. Inspect all four tyres for cuts, bulges, or uneven wear, particularly the offside rear which had a Major failure for a deep cut exposing the ply. Finally, verify that the windscreen washer system operates correctly on both front and rear jets, as this was a repeated Minor to Major failure point, and check for any oil leaks from the engine or transmission that may have developed during the unrecorded years of use, since there is no MOT evidence covering the period since late 2018.
