The most recent MOT test on 2026-06-06 recorded a clean pass at 85,051 miles, indicating the vehicle currently meets minimum roadworthiness standards. However, the maintenance trend over the past year reveals a worsening pattern of mechanical neglect. Just three days prior to this pass, the tester flagged a worn offside front suspension arm pin or bush and an offside rear tyre worn to the legal limit and on its edge. The rapid re-test suggests these items were hastily rectified to secure a pass rather than addressed as part of routine servicing. A clean pass now does not erase the underlying wear patterns that led to the immediate failure. Accumulating 85,051 miles over five years equates to roughly 17,010 miles annually, a high figure for a large luxury SUV. The mileage progression shows a notable jump of 21,455 miles between 2024-05-21 at 47,772 miles and 2025-05-13 at 69,227 miles, followed by a further 15,824 miles in the subsequent year to 2026-06-03 at 85,045 miles. This sustained high mileage accelerates the wear of consumables and drivetrain components. The edge wear on the offside rear tyre observed in June 2026 points to prolonged highway cruising combined with neglected wheel alignment checks, a common oversight with high-mileage use. A physical inspection must focus heavily on the chassis and suspension components, given the recurring issues. The June 2026 failure for a worn offside front suspension bush, coupled with the May 2025 failure for a snapped offside rear ride height sensor and inoperative headlamp levelling device, strongly suggests the air suspension system is suffering from the toll of high-mileage use. Buyers should thoroughly inspect the condition of the air springs for leaks or cracking, check the integrity of the suspension bushes across both axles, and verify the operation of the self-levelling headlights. The edge wear on the rear tyre also demands a full suspension geometry check to prevent premature future tyre replacement.
