What Problems Does the 1986 Jaguar XJS Have?
The 1986 Jaguar XJS, like many classic luxury cars, has a reputation for requiring diligent maintenance and can present a number of known issues. Electrical gremlins are a persistent concern across many Jaguar models of this era. This can manifest as malfunctioning lights, power accessories, or even issues with the fuel injection system. The wiring harnesses can degrade over time, leading to intermittent problems that can be frustrating and costly to diagnose.
Rust is another significant long-term reliability concern. Areas prone to corrosion include the sills, wheel arches, A-pillars, and the rear valence. Early inspection for any signs of rust is crucial, as extensive bodywork can be expensive. The underbody, particularly around the subframes, also needs to be checked for structural integrity.
The V12 engine, while offering a unique and smooth driving experience, is a complex piece of machinery. Overheating can be an issue if the cooling system is not meticulously maintained. This includes regular flushing of the coolant, checking hoses and the radiator for leaks, and ensuring the viscous fan clutch is functioning correctly. Spark plug changes are also a more involved process with twelve cylinders.
The Lucas fuel injection system, common in this era, can also be a source of issues if not properly maintained. While often reliable, specific components can fail, leading to poor running conditions.
The self-leveling rear suspension, while providing a comfortable ride, can be a point of failure. Leaks in the hydraulic system or failing struts can lead to a saggy rear end, affecting handling and requiring costly repairs.
Specific to the 1986 model year, it falls within the broader pre-facelift XJS era. While there weren't major model-year-specific recalls that dramatically altered the vehicle's fundamental reliability compared to adjacent years in the mid-to-late 80s, the general issues mentioned above are consistent. The transition to the HE (High Efficiency) V12 in earlier years was a positive step for performance and economy, but the core mechanical and electrical systems remained similar. Potential buyers should be aware that parts availability for some specialized components can be a challenge, and finding a mechanic experienced with these older Jaguars is highly recommended.

How long will the 1986 Jaguar XJS last?
Based on owner data and anecdotal evidence, a well-maintained 1986 Jaguar XJS can realistically be expected to achieve 150,000 to 200,000 miles, and potentially more. However, the actual lifespan is heavily dependent on the owner's commitment to regular and preventative maintenance. The V12 engine, if cared for, is known for its longevity and smoothness. Weaknesses that emerge over time primarily revolve around the electrical system and body corrosion. Seals, hoses, and rubber components will eventually need replacement due to age. The complexity of the V12 means that neglecting maintenance can lead to more significant and costly issues. Early intervention with any emerging problems is key to ensuring long-term durability. Cars that have been garaged and driven regularly, rather than stored for extended periods, tend to fare better.
What Technology & Safety Features are Included?
The 1986 Jaguar XJS, from a technological standpoint, reflects the luxury automotive standards of its era. Built-in tech and entertainment features were focused on comfort and convenience rather than cutting-edge digital integration. Standard equipment typically included an AM/FM stereo radio with a cassette player, offering a decent audio experience for the time. Power windows and power door locks were also standard, enhancing the sense of luxury and ease of use. Cruise control was another common feature, aiding in comfortable long-distance cruising.
In terms of driver-assistance features, the XJS was relatively basic. Power steering was standard, providing a comfortable albeit sometimes less communicative steering feel. The four-wheel disc brakes offered good stopping power, and the independent suspension, particularly the self-leveling rear, contributed to a smooth and stable ride. ABS (Anti-lock Braking System) was not a standard feature on the 1986 model and was not widely available as an option on the XJS until later model years.
Safety features were also characteristic of the mid-80s. Standard safety equipment included seatbelts (though not always the most sophisticated designs by today's standards), and the robust steel construction of the chassis and body offered a degree of passive safety. Crumple zones were incorporated into the design, but modern safety technologies like airbags were not yet standard, and indeed, were largely absent from the XJS lineup in 1986. Optional features were limited and mostly focused on enhancing comfort or aesthetics rather than technology or safety. Availability of features could also vary by market.
Crash-test ratings for vehicles from this era are not readily available or standardized in the way they are today. The NHTSA (National Highway Traffic Safety Administration) and IIHS (Insurance Institute for Highway Safety) did not conduct the same rigorous and comprehensive testing procedures as they do now. Therefore, specific crash-test ratings for the 1986 Jaguar XJS are not a reliable metric for comparison with modern vehicles.
