Our Verdict
This 2012 Jaguar XJ offers premium appeal but requires caution due to recent suspension and brake issues. A careful inspection is essential before purchase.
Prioritise a full suspension inspection, focusing on the fractured coil springs and rear brake discs noted in the 2024 MOT. Check service records to confirm repairs were completed. Negotiate based on the 2024 failure, but the recent MOT pass suggests improvements. Be wary of potential hidden costs from complex Jaguar systems.
The 2.993cc diesel engine offers moderate fuel economy (approx. 35-40 mpg) but will incur higher maintenance costs due to premium parts. Road tax in 2026 would be £140 annually for CO2 emissions. Insurance groups for Jaguars typically start at 25+, with repair costs likely exceeding average. Estimated annual running costs: £1,200-£1,500 including fuel, tax, and maintenance.
Inspect suspension components for wear, particularly the coil springs and rear brake discs. Check tyres for structural damage (as highlighted in the 2024 MOT) and test the windscreen washer system. Look for fluid leaks, unusual noises during test drives, and verify that all MOT remedial work was properly addressed. Confirm the vehicle's service history matches the mileage.
The vehicle has a mostly clean MOT history with recent passes, but a 2024 failure revealed significant suspension and brake wear. At 78,686 miles, it shows below-average mileage for its age, though the diesel engine and luxury credentials remain attractive.
No aggregate data available for JAGUAR XJ. However, the model has a reputation for luxury and performance, but may require careful maintenance due to its complex systems.

AI Analysis
Historical fault & advisory patterns
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.
