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.
- Timing Chain Tensioner Wear (5.0 V8)(Serious)
Early 5.0 V8 and 3.0 supercharged V6 engines have a design flaw where the timing chain tensioner piston wears through the aluminium-backed guide over time. This causes the chain to stretch and eventually jump, which can destroy the engine. The issue is most critical on pre-2013 cars.
- 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 This is typically caused by torque converter clutch issues or outdated TCM software and can often be resolved with a software reflash and fresh fluid.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.
