2012 Jaguar Xj problems

Common 2012 Jaguar Xj problems

The Jaguar XJ, produced from 2010 to 2019, is known for its luxurious design and powerful performance. However, as with any vehicle, it has its fair share of common problems.

One of the most significant issues reported by owners is related to the electrical systems, specifically around the sat-nav and infotainment systems. This can manifest in various ways, such as malfunctioning touchscreens, unresponsive buttons, or even complete system failures. It's crucial to thoroughly inspect these components during a pre-purchase inspection, as electrical issues can be costly and time-consuming to repair.

Another common problem is related to the diesel engines, particularly the DPF (Diesel Particulate Filter). This filter is designed to reduce emissions, but it can become clogged or fail, leading to reduced performance and increased fuel consumption. It's essential to verify that any necessary repairs or replacements have been carried out by a Jaguar dealer or a reputable specialist, as improper maintenance can exacerbate this issue.

For petrol models, particularly the 3.0 Supercharged V6 and 5.0 V8 engines, coolant leaks are a well-documented issue. The water pump is a known failure point, but other parts of the cooling system can also fail, leading to overheating and potential engine damage. Regularly inspecting and maintaining the cooling system is crucial to prevent these issues.

In the 2012 Jaguar XJL Portfolio, there are specific components that owners should be aware of. A small plastic transition piece that connects the water pump to the oil cooler is prone to catastrophic failure, making it difficult to detect leaks unless the system is pressure-tested. Additionally, there are numerous small plastic lines in the driver's side of the engine bay that can crack and cause fluid loss. These issues can lead to overheating and engine damage if not addressed promptly.

Lastly, it's worth noting that the XJ saloons are built for long-distance cruising and are generally reliable for this purpose. However, regular maintenance and prompt attention to any issues are crucial to ensure a trouble-free ownership experience.

What is the best Jaguar XJ engine?

By far the most popular engine choice is the twin-turbocharged, 3.0-litre V6 diesel – found in various Jaguar Land Rover products – and this 300hp engine is superbly refined and near silent at cruising speeds.

Are Jaguar XJ expensive to maintain?

In short, yes — Jaguars cost a pretty penny throughout their lifetimes. On average, Jaguars cost $1,123 per year to maintain and repair, according to RepairPal (a site that estimates automotive repair costs).
