V-shaped engines like the one in the 2015 Range Rover Sport often experience oil leaks due to the complexity of the design and multiple seals and gaskets.

Supercharged engines may encounter problems with the supercharger itself, including bearing wear, belt issues, or boost pressure inconsistencies.

The V6 configuration in the Range Rover Sport can be prone to timing chain wear and stretching, which can lead to engine misfires or even catastrophic failure if not addressed.

Supercharged engines generate more heat, increasing the likelihood of cooling system problems such as radiator leaks, water pump failures, and coolant hose deterioration.

Positive Crankcase Ventilation (PCV) valves can get clogged or fail over time, leading to increased oil consumption or engine sludge buildup.

Direct injection systems in supercharged engines may experience fuel injector clogs or failures, leading to poor engine performance and increased emissions.

The direct injection in supercharged engines can result in carbon deposits on the intake valves, reducing engine efficiency and performance.

Complex engine management systems in modern vehicles like the Range Rover Sport can suffer from sensor failures (e.g., MAF, O2 sensors), leading to poor performance and diagnostic trouble codes.

Oil leaks can occur around the valve cover gaskets or the oil pan, leading to reduced engine lubrication and potential engine damage.

The timing chain can wear out or become loose, causing poor engine performance or even catastrophic engine failure.

Since this model has a supercharged engine, the supercharger can fail or experience wear, leading to reduced power and performance.

Fuel injectors can become clogged or fail, leading to misfires, poor fuel economy, and reduced engine performance.

Worn or faulty spark plugs can cause misfires, rough idling, and poor acceleration.

Problems with the radiator, water pump, or thermostat can lead to engine overheating, which can cause severe engine damage.

Faulty oxygen sensors can lead to poor fuel mixture and reduced fuel efficiency.

A failing MAF sensor can cause incorrect air-fuel ratio, leading to poor engine performance and increased emissions.

Leaks in the vacuum system can cause rough idling, stalling, and poor acceleration.

A faulty camshaft position sensor can cause poor engine performance, stalling, and difficulty starting the engine.

Misfires can be caused by various issues such as faulty spark plugs, ignition coils, or fuel injectors. In a V-shaped engine configuration, accessing cylinders can be more complex.

Some engines are known to consume more oil, which can necessitate frequent top-ups and monitoring to prevent engine damage.

V6 engines, especially in high-performance models, can experience timing chain stretch or wear, leading to engine noise and potential performance issues.

If the model includes a turbocharger, it could face issues like turbo lag or failure, often due to oil contamination or poor maintenance.

High-performance engines like the S/C LEV3 SULEV30 can generate significant heat, stressing the cooling system and potentially leading to coolant leaks or overheating.

Problems with fuel pumps or injectors can lead to poor engine performance or stalling, particularly if the vehicle isn't maintained regularly.

Modern engines often use electronic throttle control, which can sometimes malfunction, leading to throttle response issues.

As a SULEV (Super Ultra-Low Emission Vehicle), it has advanced emission control systems that can be prone to faults, leading to check engine lights and potential performance issues.

The DBS system, while useful for safety, can sometimes malfunction, leading to unexpected braking behavior or warning lights.

Over time, components in the exhaust system like catalytic converters or mufflers can wear out or get clogged, affecting engine performance and emissions.

DBS uses sensors to detect potential collisions and automatically applies the brakes. Malfunctions can lead to delayed or insufficient braking assistance.

The AJ126 engine has been known to develop coolant leaks, which can cause overheating and engine damage if not addressed.

The timing chain tensioner on the AJ126 engine can wear out, leading to timing chain rattle and potential engine misalignment.

Direct injection engines like the AJ126 can accumulate carbon deposits on intake valves, leading to reduced performance and fuel efficiency.

The 2018 Range Rover Sport with the AJ126 engine may experience supercharger whine or noise due to worn bearings or issues with the supercharger drive belt.

The AJ126 engine may develop oil leaks from valve cover gaskets or other seals, leading to oil consumption and potential engine damage.

For variants equipped with a turbocharger, there can be issues with the turbocharger failing, leading to reduced power and potential engine damage.

The 2018 Range Rover Sport is known for various electrical issues, including problems with the infotainment system, sensors, and wiring harnesses.

The air suspension system in the Range Rover Sport can fail, leading to a rough ride, uneven ride height, and expensive repairs.

The ZF 8-speed automatic transmission used in the Range Rover Sport can have problems with shifting, hesitation, and transmission fluid leaks.
