2003 Jaguar XJ 3.0L Petrol · ST03 YOR

The 2026 MOT failure on 2026-05-29 highlights significant issues, including a defective windscreen wiper blade, excessive wear in the offside front suspension component, and rear sub-frame corrosion. These defects indicate ongoing mechanical degradation, particularly in suspension and structural components. The most recent failure is the second in under two months, suggesting a pattern of emerging risks rather than isolated incidents. A prior MOT on 2026-04-21 revealed a far more extensive list of failures, including multiple tyre tears, brake disc wear, suspension dust cover damage, and electrical faults like an inoperative engine MIL and ABS warning lamp. These issues span critical areas such as braking, steering, and safety systems, with recurring problems like suspension component wear and corrosion appearing across multiple tests. The 2016 MOT noted minor suspension play, but subsequent tests show a clear escalation in severity. The vehicle’s mileage of 151,012 miles over 23 years equates to roughly 6,566 miles annually, which is typical for its age. This suggests neither extreme under-use nor heavy wear from high mileage. However, the frequency of suspension, tyre, and corrosion-related defects implies potential exposure to harsh conditions or insufficient maintenance. The repeated mention of corrosion (e.g., rear sub-frame, fuel tank mounts) and worn suspension components raises concerns about long-term structural integrity.
