1 KHB MOT History
Interpretation generated from the recorded test data above — not an official DVSA statement and not a substitute for an independent inspection.
19 MOT tests are recorded for this 2004 Jaguar Xj (1 KHB) between April 2007 and November 2025.
The record contains 17 passes and 2 failures.
The most recent test on 21 November 2025 was a pass, although the earlier record includes 2 failures that buyers may want to investigate.
Across all tests, the most frequently flagged areas are: Brakes (8 issues), Tyres (3 issues), Windscreen (2 issues), Suspension (2 issues). Repeated mentions in one area can indicate an ongoing pattern worth checking in person.
In total 6 advisory notices are recorded. Advisories flag items that passed but may need attention before the next test; they are not evidence of how well the vehicle has been serviced.
Recorded failure items include: “Offside Rear Tyre tread depth below requirements of 1.6mm (4.1.E.1)”; “Parking brake: efficiency below requirements (3.7.B.7)”; “Nearside Front Tyre has a bulge, caused by separation or partial failure of its structure (4.1.D.1b)”.
Common Problems: JAGUAR XJ
Known issues reported by owners and MOT testers.
- Air Suspension Failure(Serious)
Air struts leak or the compressor fails to reach pressure, leaving the car "slammed" on its bump stops.
- Aluminum Corrosion (X350)(Moderate)
Although it won’t rust like steel, the X350 suffers from galvanic corrosion, appearing as bubbling paint around the wheel arches and boot lid.
- ZF Gearbox Surging & Lurch(Moderate)
The ZF six-speed automatic gearbox can develop surging on light throttle at 30-50mph and harsh lurching into gear when coming to a stop. This is typically caused by torque converter clutch issues or outdated TCM software and can often be resolved with a software reflash and fresh fluid.
- Door Lock & Window Regulator Failures(Moderate)
The door lock actuators and window regulators are common failure points on the X350. Lock failures can leave doors stuck in the double-locked position, while window regulators fail with the cable-driven mechanism snapping or the motor burning out.
