What Problems Does the 1998 Jaguar XJ-Series Have?
The 1998 Jaguar XJ-Series, particularly the X308 generation, is known for certain mechanical and electrical quirks that owners should be aware of. One of the most frequently reported issues is related to the Nikasil cylinder liners in the early 4.0L V8 engines (pre-2000 models). While not a universal problem, these liners could degrade over time, especially with higher sulfur content in fuel, leading to poor compression and engine damage. Later models (from around 2000 onwards) switched to a different liner material to address this.
Cooling system problems are also quite common. Plastic coolant pipes, particularly the thermostat housing and the connection points to the radiator, are prone to becoming brittle with age and can crack, leading to significant coolant leaks and potential engine overheating if not addressed promptly.
Electrical gremlins are another hallmark of older Jaguars. This can manifest in various ways, from intermittent dashboard warning lights and malfunctioning power accessories (like windows or central locking) to issues with the ABS or traction control systems. The complexity of the wiring harnesses, combined with age, can lead to corroded connections and faulty sensors.
Transmission issues, while not as prevalent as some other problems, can occur. The ZF automatic transmissions used in these cars are generally robust, but age, lack of proper fluid changes, or overheating can lead to slipping or harsh shifting.
Rust is a concern, especially on vehicles that have lived in areas with harsh winters or high humidity. Key areas to inspect include the rear wheel arches, rocker panels, and the boot floor.
Regarding recalls, specific recalls for the 1998 model year would need to be checked against VIN databases, but common areas for potential manufacturer attention in this era of Jaguars often involved airbag systems, brake components, or specific engine/transmission control module updates. Long-term reliability heavily depends on diligent maintenance and addressing issues proactively. Owners who invest in regular servicing and are prepared for the potential of more involved repairs tend to have better experiences.

How long will the 1998 Jaguar XJ-Series last?
Estimating average mileage for a 1998 Jaguar XJ-Series can vary significantly, but many examples, with diligent maintenance, are still operational with well over 150,000 miles. Some owners report their cars exceeding 200,000 miles. The long-term durability of the engine and transmission is largely contingent on the proactive addressing of known issues like the Nikasil liners (on earlier models) and regular coolant changes to prevent overheating. The robust ZF automatic gearbox, when properly serviced, can last a long time. However, the car's electrical systems and susceptibility to rust represent its primary weaknesses over time. Neglected maintenance, particularly concerning the cooling system, can drastically shorten its service life. With consistent care and investment, the XJ-Series can offer many more years of luxurious service.
