2004 Nissan X-Trail 2.2L Diesel · AF54 KXK

Chronic corrosion and persistent underbody degradation form the defining mechanical narrative of this 2004 Nissan X-Trail, with two failures and a string of advisories over the past five MOT tests all pointing toward the same progressive deterioration. The most recent test on 11 January 2025 returned a pass but carried advisories for an oil leak (not excessive) and general underbody corrosion, continuing a trend that has worsened gradually since 2022. That year produced a failure with a major defect for an excessively corroded nearside rear suspension mounting area at the inner wheel arch, and the 2023 retest failed again on the same category of defect, this time on the offside rear, alongside a major for brake performance unable to be tested due to excessively binding front service brakes on both sides. The 2024 pass then flagged rear subframe corrosion (not excessive) and further binding front brake advisories. This is a vehicle where structural integrity at the suspension mounting points is the principal concern, and where the underbody corrosion has been visibly progressing across consecutive tests. Mileage accumulation sits at roughly typical levels for the vehicle's age, with 144,036 miles recorded across approximately 22 years, equating to around 6,547 miles annually. The MOT record shows no extended gaps in testing or sudden mileage jumps between consecutive tests, with the odometer reading progressing steadily from 2021 onwards. There is no indication in the DVSA data that the vehicle was laid up for any multi-year period, so corrosion findings are not attributable to long-standing neglect but rather to the gradual exposure typical of a high-mileage SUV of this vintage operating through British winters. The combination of above-average wear items such as brake binding, anti-roll bar linkage wear, and the recurring oil leak across virtually every test is broadly consistent with sustained road use rather than sporadic operation. For a prospective buyer, the suspension and underbody findings warrant the closest physical scrutiny. On a test drive, listen for clonks or knocks over uneven surfaces, particularly from the rear, where two major defects have already been recorded for excessively corroded mounting prescribed areas at the inner wheel arches; press down firmly on each rear corner and check for slow, uncontrolled rebound suggesting compromised strut towers or weakened mounting metal. Inspect the sills, rear subframe, and inner wheel arches with a torch and magnet for any bubbling, perforation, or paint bubbling that would indicate corrosion beyond what the advisories described, paying particular attention to the areas flagged in 2022 and 2023. The 2021 advisory noted sills described as soft, and a buyer should confirm whether any remedial welding has been carried out since. The braking system requires equally careful evaluation. The 2023 failure specifically cited both front service brakes excessively binding, and binding advisories on both front corners resurfaced on the 2024 pass, suggesting the calipers or guide pins may not have been fully rectified between tests. On a road test, expect to feel any pulling to one side under firm braking, uneven pad wear visible through the wheel spokes, or a hot wheel smell after driving. Check that the brake pedal feels firm and that the vehicle stops squarely without judder. The recurring oil leak advisory also warrants a check of the engine bay and undertray for fresh residue, while the 2024 failure for non-functional windscreen wipers and offside front position lamp, although rectified at the same test, indicates electrical ancillaries that should be verified as fully operational at the point of purchase.
