2014 Jaguar XK 5.0L Petrol · XK07 COL

Persistent corrosion on the rear sub-frame represents the primary mechanical concern for this vehicle, as this advisory has appeared in two consecutive tests, most recently on 13 October 2025. While the 2025 pass indicates the corrosion was not recorded as seriously weakened at that time, the recurrence of this specific advisory from the 2024 test suggests a continuing degradation of the structural component. This trend of sub-frame corrosion is the most significant long-term issue identified in the recent MOT history, contrasting with a previous period of clean records between 2020 and 2023. The vehicle has covered 68,135 miles over its approximately twelve-year lifespan, which averages to roughly 5,678 miles per year. This represents a low annual mileage profile for a vehicle of this age and type. While lower mileage typically implies less wear on drivetrain and engine components, the records show specific instances of tyre-related failures and advisories, notably a dangerous failure in October 2023 due to a structural bulge in the nearside rear tyre. This pattern of tyre wear and occasional structural tyre defects, alongside the low mileage, can sometimes be associated with vehicles that spend extended periods stationary or are driven on a limited number of routes. A physical inspection of the underside is essential to assess the extent of the rear sub-frame corrosion. During a test drive, pay close attention to any unusual noises coming from the rear of the car, such as knocks, clunks, or creaks when navigating uneven surfaces or speed bumps, as these can indicate that the corrosion is beginning to affect the integrity of suspension mounting points or bushings. It is also advisable to check for any signs of movement or play in the rear suspension assembly. The history of tyre advisories and the 2023 failure for a tyre bulge suggest that tyre condition and replacement intervals should be closely monitored. On a test drive, ensure the vehicle tracks straight under braking and does not pull to either side, which would indicate uneven tyre wear or alignment issues. Given the low annual mileage, verify that the tyres do not show signs of sidewall cracking or perishing from age, even if the tread depth appears sufficient.
