Jaguar XJ8 Problems

Broken Lug Nuts

While getting my tires changed one of my lug nuts was broken. Had to go to another shop to loosen the rest of the lug nuts and then return to have my tires installed.

The three piece lug nuts are fragile, and if the tires are not rotated frequently, the lug nuts can seize. Lubricate the threads when changing tires and purchase several spares to have on hand for an emergency.

fuel pump went out.

my car would turn over but it would stall out.

Engine Noise While Idling or After Cold Start

On this V8 engine, timing chain problems are very common. Because the timing chain tensioners were made from plastic, they can fail prematurely and cause serious engine damage. A noticeable engine noise while idling or during a cold start can indicate a timing chain tensioner problem. The engine noise may also be accompanied by a rough or uneven engine idle. Improved components are available to remedy this problem.

Jaguar XJ8 Recalls

Jaguar Recalls 2004 XJ Models for Possible Accelerated Brake Line Corrosion

Jaguar is recalling 2004 model year XJ vehicles to prevent and correct possible accelerated corrosion of the rear steel brake lines. The existence of a special pad installed to reduce noise, vibration, and harshness under the vehicle in a location where it contacts with the steel brake lines creates an environment where moisture and dirt can collect and promote accelerated corrosion. Corroded brake lines can develop leaks, causing brake system pressure failure and poor braking function. Dealers will remove the special pad and inspect the brake lines for the existence of corrosion. Affected lines will be replaced.
