Rolls-Royce engines, including the 12-cylinder in the 2014 Wraith, can sometimes develop oil leaks over time, especially around seals and gaskets.

Given the power of the engine, cooling system components like radiators and water pumps may be prone to failure or inefficiency, leading to overheating problems.

The ignition coils in high-performance engines like the Wraith's can wear out, causing misfires and reduced performance.

Issues with the fuel injectors or fuel pump can occur, leading to poor fuel economy and engine performance.

Over time, the timing chain may stretch or wear out, potentially causing timing issues and engine noise.

If equipped with a turbocharger, it may experience wear or failure, leading to reduced engine performance and efficiency.

Common in high-performance engines due to the high pressure and temperature in the engine, leading to seals and gaskets wearing out.

High-performance engines like the 12-cylinder in the Rolls-Royce Dawn generate a lot of heat, which can overwhelm the cooling system if not properly maintained.

The powerful 12-cylinder engine consumes more fuel, making it less efficient and potentially leading to higher costs and more frequent refueling.

High-performance engines can suffer from carbon deposits on valves and pistons, which can affect performance and fuel economy.

Could be due to issues with spark plugs, fuel injectors, or ignition coils, especially in a complex 12-cylinder configuration.

High-performance engines can place more stress on the timing components, leading to potential failures if not regularly inspected and maintained.

Issues with the Dynamic Brake Support (DBS) system can include sensor malfunctions, software glitches, or failures in the electronic control unit (ECU) that manages the system.

High-performance engines like this can experience problems such as overheating, excessive wear and tear on components, and potential issues with the turbocharger or supercharger.

A V12 engine can encounter problems such as misfiring, imbalance in the cylinders, or difficulties with the timing chain/belt. Maintenance can be more complex and costly due to the number of cylinders.

Rolls-Royce vehicles, while luxurious, can have issues related to their complex electronic systems, air suspension, and high cost of replacement parts and service.

Convertible models like the Rolls-Royce Dawn can face problems with the convertible top mechanism, including leaks, motor failures, and issues with the seals.

As vehicles age, common problems for a 2017 model year can include wear and tear on the suspension, issues with the infotainment system, and general degradation of rubber components (seals, gaskets, etc.).
