The 2018 Jaguar XJ-Series represents the final model year of a distinguished British luxury sedan known for its elegant design and refined performance. This large executive car, produced from 2010 to 2019, offered a blend of traditional Jaguar craftsmanship with modern amenities. Key trims included the XJL Portfolio and the performance-oriented XJR575. Its popularity stemmed from its distinctive styling, comfortable ride, and powerful engine options, offering a sophisticated alternative in the luxury sedan market.
			The Good
The 2018 Jaguar XJ-Series excels with its striking, timeless design that elicits emotional appeal. Performance is a strong suit with potent engine options, while its exceptionally comfortable and luxurious interior caters to practical buyers seeking a serene driving experience. It offers a unique blend of spirited driving and opulent refinement.
The Bad
Potential buyers should be aware of some reported electrical gremlins and infotainment system glitches, which can be frustrating. The aging platform, even in its final year, meant some technology felt less cutting-edge compared to newer rivals, and maintenance costs can be higher than average.

What Problems Does the 2018 Jaguar XJ-Series Have?
  While the 2018 Jaguar XJ-Series generally garnered praise for its driving dynamics and luxury, some owners have reported recurring issues. Electrical problems are a notable concern, often manifesting as minor glitches with the infotainment system, such as freezing screens or non-responsive controls. Some drivers have also experienced issues with warning lights illuminating on the dashboard without apparent cause. Battery drain has been cited as another potential problem, sometimes linked to the vehicle's complex electronics or parasitic draws. 
Mechanical concerns, though less frequent, can include issues with the air suspension system, particularly on higher mileage vehicles, leading to a less comfortable ride or requiring costly repairs. Transmission shifts can sometimes be less smooth than expected, though this is often subjective.
Recalls for the 2018 model year are less extensive than for some earlier years, but it's always wise to check the NHTSA database for any outstanding recalls specific to a vehicle's VIN. For example, certain Jaguar models from this era have had recalls related to airbag inflators or potential fuel leaks.
Long-term reliability is a mixed bag. While the core powertrain can be robust with proper maintenance, the sophisticated electronic systems are where most potential headaches lie. Buyers should factor in the possibility of higher-than-average repair costs, especially for electrical components or specialized systems. Model year 2018, being the last of its generation, often benefited from refinements made in previous years, potentially mitigating some earlier issues, but the inherent complexity of luxury vehicle electronics remains a factor.

How long will the 2018 Jaguar XJ-Series last?
  Based on owner data and typical luxury sedan usage, a well-maintained 2018 Jaguar XJ-Series can reasonably be expected to last between 150,000 to 200,000 miles, or approximately 10-12 years of service. Long-term durability hinges significantly on consistent, high-quality maintenance, particularly concerning fluid changes for the engine, transmission, and differential. The supercharged V6 and V8 engines are generally robust, but their longevity is tied to regular servicing. The primary weakness that emerges over time is often related to the vehicle's complex electrical systems and sensors, which can become more prone to minor malfunctions as the car ages, potentially leading to more frequent, albeit often smaller, repair bills.
			What Technology & Safety Features are Included?
  The 2018 Jaguar XJ-Series offers a sophisticated suite of technology and safety features, though some aspects reflect its aging platform. Standard tech includes an 8-inch touchscreen infotainment system with navigation, Bluetooth connectivity, and Jaguar's InControl Apps. The Jaguar Sound System provides a decent audio experience, with optional upgrades to a premium Meridian system for audiophiles. 
Driver-assistance features on the 2018 XJ generally include parking sensors (front and rear) and a rearview camera. Optional packages often added more advanced systems such as blind-spot monitoring, lane departure warning, adaptive cruise control with intelligent emergency braking, and traffic sign recognition. Higher trims and optional packages could also equip the XJ with surround-view cameras and enhanced parking aids.
Safety is bolstered by a strong structure and a comprehensive airbag system, typically including front, side, and curtain airbags. Anti-lock brakes (ABS), electronic stability control (ESC), and traction control are standard.
While official crash-test ratings for the 2018 Jaguar XJ specifically from NHTSA or IIHS can be scarce due to its niche market and end-of-production status, its predecessor models generally performed well in crash simulations. Jaguar vehicles of this era typically achieve good scores in frontal and side-impact tests. However, the absence of some of the latest, most advanced driver-assistance technologies as standard, compared to newer competitors, is a notable point. The infotainment system, while functional, might feel less intuitive and responsive than those found in more contemporary luxury vehicles.

2018 Jaguar XJ-Series Prices and Market Value
  When new, the 2018 Jaguar XJ-Series had a starting MSRP typically in the range of $76,000 for the standard wheelbase models, extending upwards of $90,000-$100,000 for long-wheelbase and the high-performance XJR575 variant. 
Currently, used 2018 Jaguar XJ-Series models can be found ranging from approximately $25,000 to $45,000, depending heavily on mileage, condition, trim level, and options. The XJR575 commands a premium.
Depreciation for the XJ is quite steep in the first few years, typical for luxury sedans. Factors affecting resale value include the overall reputation for reliability (which can be a concern for some buyers), condition of the interior and exterior, maintenance history, and current market demand for luxury sedans versus SUVs. Well-maintained, lower-mileage examples, especially desirable trims like the Portfolio or XJR575, will retain value better than average.
