2016 Jaguar XJ 3.0L Diesel · YA66 GYZ

This Jaguar XJ presents a stable and improving maintenance trend, culminating in a clean pass on 4 June 2026 at 58,628 miles with zero defects recorded. That clean sheet follows a same-day failure for an inoperative engine MIL, which was clearly rectified immediately. The trajectory from the fractured coil spring and structural tyre damage flagged in late 2023 to a fully defect-free result today suggests attentive recent ownership and a commitment to resolving serious mechanical faults rather than ignoring them. The mileage profile is notably low for a 2016 vehicle, averaging roughly 5,863 miles per year. The record shows a gap of approximately 14 months between the December 2023 test at 48,444 miles and the April 2025 test at 53,088 miles, during which the car covered 4,644 miles. The subsequent jump to 58,628 miles by June 2026 represents 5,540 miles in just over a year, indicating a shift from very light use to more regular driving. This pattern implies the vehicle may have sat stationary for extended periods, a scenario that can cause flat-spotted tyres, seized brake calipers, and dried-out rubber bushes despite the low overall mileage. A buyer should focus the physical inspection on the front suspension and wheel assemblies. The December 2023 failure identified a fractured offside front coil spring and a structural sidewall bulge on the same side, indicating a significant impact event. While both were replaced, the front subframe, lower wishbones, and track rod ends on that side must be inspected for bent components or uneven bush wear that could cause premature tyre wear or steering vagueness. The nearside front tyre was also flagged as worn to the legal limit in April 2025, suggesting possible alignment drift or a worn suspension joint on that corner. The braking system and engine management require a brief road test. The 2025 advisory on rear tyre condition combined with the low-mileage profile raises the question of binding rear calipers or a sticking handbrake, so a post-drive heat check of the rear wheels is advisable. The same-day engine MIL failure in June 2026 points to a recent emissions sensor or ECU issue that was fixed, but a diagnostic scan should confirm no stored fault codes and that all readiness monitors are complete. Structurally, the low mileage and clean recent pass are encouraging, but a thorough underbody inspection for corrosion is still warranted given the car's age and potential for long stationary periods.
