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 This is typically caused by torque converter clutch issues or outdated TCM software and can often be resolved with a software reflash and fresh fluid.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.
