Analysis
What Problems Does the 2005 Jaguar XJ-Series Have?
The most prominent issue is the sophisticated active air suspension system. Components such as the air compressor, air springs (struts), and height sensors are prone to failure with age. Owners often report one or more corners of the vehicle sagging, the "Vehicle Too Low" warning appearing, or the compressor running excessively, all indicating expensive repairs.
Electrical gremlins are another common complaint. These can manifest as intermittent dashboard warning lights, malfunctioning infotainment systems, faulty power window regulators, or mysterious battery drain issues often caused by modules not properly entering 'sleep' mode.
A noticeable aesthetic problem, particularly in regions with strong sunlight, is dashboard leather delamination, where the leather shrinks and separates from the underlying material, leading to an unsightly appearance and a costly fix.
While the ZF 6HP26 automatic transmission is robust, transmission fluid leaks from the mechatronic sleeve or pan gasket are not uncommon as the seals age, requiring specialized fluid and servicing. The cooling system also has its weaknesses, with various plastic components like the thermostat housing and expansion tank becoming brittle and prone to cracking, potentially leading to coolant leaks and engine overheating.
Other reported issues include premature wear of suspension control arm bushings, which can impact ride quality and alignment, and occasionally seized brake calipers. For the 2005 model year specifically, a recall addressed a potential cracking issue with the front lower control arm in a limited number of vehicles. It's crucial for any potential buyer to check for outstanding recalls using the VIN.
Long-term reliability hinges heavily on consistent and proactive maintenance. Parts can be expensive and sometimes difficult to source, and specialized labor is often required, driving up ownership costs. The aluminum body, while beneficial for performance, can make accident repairs more complex and costly. While the core engine and transmission are durable if cared for, the ancillary systems, especially the air suspension and electronics, demand significant attention over time.
How long will the 2005 Jaguar XJ-Series last?
A significant long-term durability strength is the all-aluminum body, which is impervious to rust, a common killer of older vehicles. The robust V8 engines and ZF automatic transmissions are mechanically sound and capable of high mileage if regular fluid changes are adhered to.
However, long-term weaknesses primarily revolve around the air suspension system, which typically requires major component replacement (compressor, springs/struts) between 80,000 and 120,000 miles due to natural wear. Electrical systems and aging sensors can also develop intermittent faults over time. Interior materials like dashboard leather and headliners may show signs of age or delamination. Regular replacement of wear items such as suspension bushings and engine mounts is also crucial to maintain its signature ride quality and prevent further issues. Diligent, preventative maintenance is absolutely vital for extended reliable service.
What Technology & Safety Features are Included?
Driver-assistance features, advanced for 2005, included standard or optional rear parking sensors to aid maneuvering. A notable optional feature was Adaptive Cruise Control (ACC), which utilized radar technology to automatically maintain a set distance from the vehicle ahead. Other conveniences included automatic headlights and rain-sensing windshield wipers.
In terms of safety, the XJ was well-equipped. It featured a comprehensive suite of passive and active safety systems, including an Anti-lock Braking System (ABS), Dynamic Stability Control (DSC), and Traction Control to maintain vehicle stability. Occupant protection was provided by front, seat-mounted side, and full-length side curtain airbags, along with seatbelt pretensioners. A Tire Pressure Monitoring System (TPMS) was also included. High-Intensity Discharge (HID) headlights were often an optional upgrade for improved nighttime visibility.
Regarding crash-test ratings, the 2005 Jaguar XJ-Series, like many luxury vehicles of its segment and time, was not typically subjected to official crash testing by U.S. agencies such as NHTSA or IIHS. Therefore, comprehensive crash-test ratings are generally unavailable for the U.S. market. However, its sophisticated aluminum monocoque chassis was engineered for significant structural rigidity, inherently contributing to passive safety performance.

How Does the 2005 Jaguar XJ-Series Compare to Other Sedan?
In terms of performance, the XJ, especially in supercharged XJR or Super V8 guise (390 hp), offered robust acceleration and surprising agility for its size, thanks to its lightweight aluminum construction. This put it squarely against V8 variants of the S-Class, 7 Series, and A8, all of which offered impressive power and refinement, with BMW often leading in sporty handling. The Lexus LS 430, while smooth, was generally less performance-focused.
Regarding features, the XJ exuded classic British elegance with abundant wood and leather, plus a touchscreen interface that was modern for its time. Mercedes' S-Class offered cutting-edge tech like the COMAND system and Active Body Control (ABC) suspension, providing a more overtly modern luxurious experience. BMW's 7 Series, with its pioneering iDrive system, focused on driver engagement and sophisticated electronics. The Audi A8 showcased understated luxury, exceptional build quality, and the advantage of Quattro all-wheel drive. The Lexus LS 430 excelled in quiet refinement and bulletproof quality of its well-appointed, though perhaps less ostentatious, cabin.
Reliability is where the class diverges significantly. While the Jaguar XJ saw improvements over previous generations, it still contends with known air suspension and electrical issues that can be costly. Its European rivals, the W220 S-Class and E65/E66 7 Series, were also notorious for complex electronics, suspension problems, and high repair costs, often surpassing the XJ. The Audi A8 (D3) generally offered a slightly better reliability record among the Germans, though its air suspension could still be a weak point. The undisputed champion for long-term reliability in this segment is the Lexus LS 430, known for its exceptional durability and significantly lower repair frequency.
Price on the used market shows steep depreciation for all these luxury sedans. The Jaguar, Mercedes, and BMW typically reside in a similar depreciated bracket, offering immense luxury for a fraction of their original cost but with high running expenses. The Lexus LS 430, while also depreciated, often commands a slightly higher premium due to its legendary reliability.
For buyers prioritizing ultimate reliability and lower long-term ownership costs, the Lexus LS 430 is the clear, practical alternative. If a sophisticated European driving experience with slightly more modern features than the XJ is desired, the Audi A8 (D3) is a strong contender, especially with its Quattro AWD. However, if the unique British charm, elegant design, and the spirited driving dynamics of an aluminum chassis are paramount, the 2005 Jaguar XJ-Series stands as a distinctive choice that rivals cannot fully replicate.
