Question 1

What is Air Suspension Failure on the Jaguar Jaguar XJ (X350/X351)?

Accepted Answer

Air struts leak or the compressor fails to reach pressure, leaving the car "slammed" on its bump stops.

Question 2

What is Aluminum Corrosion (X350) on the Jaguar Jaguar XJ (X350/X351)?

Accepted Answer

Although it won’t rust like steel, the X350 suffers from galvanic corrosion, appearing as bubbling paint around the wheel arches and boot lid.

Question 3

What is Timing Chain Tensioner Wear (5.0 V8) on the Jaguar Jaguar XJ (X350/X351)?

Accepted Answer

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.

Question 4

What is ZF Gearbox Surging & Lurch on the Jaguar Jaguar XJ (X350/X351)?

Accepted Answer

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 This is typically caused by torque converter clutch issues or outdated TCM software and can often be resolved with a software reflash and fresh fluid.

Question 5

What is Door Lock & Window Regulator Failures on the Jaguar Jaguar XJ (X350/X351)?

Accepted Answer

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.

Question 6

What should I check when buying a used Jaguar Jaguar XJ (X350/X351)?

Accepted Answer

On X350 models, look for "white powder" under the paint; this is aluminum corrosion (oxidization) and is common on rivets.

Question 7

What should I check when buying a used Jaguar Jaguar XJ (X350/X351)?

Accepted Answer

On X351 models (2010+), check the sunroof for popping or creaking sounds—a common issue often requiring new subframe bolts.

Question 8

What should I check when buying a used Jaguar Jaguar XJ (X350/X351)?
