2015 Jaguar XF 2.2L Diesel · CB15 AJB

The vehicle’s roadworthiness trend is worsening , with a failure in March 2026—just four weeks before passing—highlighted by persistent tyre wear and critical structural corrosion. The most recent failure (2026-03-05) exposed a rear subframe mounting corroded to the point of compromising vehicle control, a fault that had been previously noted but not escalated. The front brake discs, while not excessively worn, show consistent wear across multiple tests, and the rear brake system has exhibited binding and fluctuating performance in prior failures. This suggests a pattern of deferred maintenance, particularly around critical safety components. The recorded mileage of 44,090 miles over 11 years—roughly 4,008 miles annually—indicates unusually light usage for its age, which may mask deeper issues. The gap between tests is irregular: the vehicle sat for 11 months between the 2025 and 2026 tests, despite the low mileage. This prolonged inactivity could accelerate corrosion, particularly in the rear subframe, which was flagged as corroded in every test since 2024. The lack of significant mileage accumulation does not negate the need for thorough inspection of components that degrade over time regardless of usage, such as suspension mounts and structural welds. A buyer should prioritise an immediate inspection of the rear subframe mounts and lower control arms , where corrosion has progressed to a failure-critical stage. The offside rear brake binding and fluctuating pedal noted in 2024 suggests potential caliper seizure or excessive wear, requiring verification of hydraulic lines and disc thickness. Front tyre wear—consistently close to the legal limit—demands confirmation of alignment and tread depth, as edge wear often indicates misalignment or suspension misadjustment. Finally, the recurring oil leak advisories warrant checking for worn seals in the differential or transmission, though these are less urgent than the structural and braking concerns.
